Temperatures seem consistent (I did re-run the PID calibration, and the silicone sock should help).

#

I did put thermal compound between the heatbreak and heatsink.

#

My current guess is that the filament has absorbed some moisture, as it is some I bought before I got the airtight filament storage containers and dessicant. Perhaps it's time to build a filament dryer.

crude kettle
#

Is the temp sensor the same as the last one?

karmic brook
#

Yes, same temperature sensor.

crude kettle
#

Is the cooling fan okay?

karmic brook
#

Cooling fan seems fine, it's spinning, not obstructed, and doesn't seem to have anything tangled up in it.

crude kettle
#

Well what filament is it?

karmic brook
#

Makergeeks Raptor PLA

crude kettle
#

Is it an all metal hotend?

karmic brook
#

The actual hot part is (aside from the silicone sock), but the framework is mostly printed.

crude kettle
#

Is you retraction distance the same? I'm asking because my printer is doing well with PETG but can't do PLA because the filament gets stick in the heat sink. The heat is not being cooled enough or the fan is not consistently keeping it cool.

karmic brook
#

I was having that problem previously, which is why I rebuilt the hotend. The retraction distance shouldn't have changed.

crude kettle
#

Now that I recall I put connecters on my wires. It may be that is my issue.

For you try out an other roll. It may be the roll or a heat sink cooling issue

karmic brook
#

Yeah, I think the easiest thing to try next is another roll.

crude kettle
#

Yeah just did the straight solder and the fan sounds like it's spinning faster. Listen to the fan speed as it prints for the heatsink

karmic brook
#

Before I rebuilt the hotend, I had lowered the print (not heatsink) fan speed to avoid the "thermal runaway" problem. It sounded like a tiny haunted leaf blower as the fan speed varied.

crude kettle
#

What's your printer again?

karmic brook
#

Prusa i3 MK3S

crude kettle
#

Most likely a bad roll

karmic brook
#

I'm beginning to think so. I'll try some different filament, and if that helps, I'll see if drying the misbehaving roll helps.

crude kettle
#

Mine is an ender 3 with an all metal hot end mod. The heat sink needs work on my part.

#

It may be the aluminum alloy transfer too well.

#

On the e3d clone hotend

karmic brook
#

I picked up one of the beta heatsinks https://www.printedsolid.com/products/e3d-beta-threaded-heatsink-1-75mm when I was buying hotend parts, I'm seeing if I can integrate it into the Prusa.

spice estuary
#

To show how tired I am, I thought that was a dummy load from first glance

crude kettle
#

There is a screw top there. Interesting to see that put in the Prusa

#

Been trying to print a nerd gun from Thingivers. Tried pla and that fail at first. A tip I found was to lube the filament with vegi oil

#

No complaints about the oil yet

karmic brook
#

The Prusa currently has a groove mount, so I'd have to make a modified hotend to use the screw mount heatsink. It comes with the matching nut, so I wouldn't necessarily have to supply the threaded mount myself.

crude kettle
#

Sounds like a cool idea. I'm going to experiment with water cooling. The top layer of that cube didn't go well. I like PETG and my printer does very well with it, but I have a lot of PLA and I want to print with that. It may be over kill but it will make my printer look cool.

karmic brook
#

I have upgraded my filament storage. Instead of a wall rack, they now live in weather-tight boxes with foam gaskets, along with some indicating dessicant.

I just started using my 3D Printer again today, (it has been in it's box for a couple months due to me not having room for it and other reasons). The print started out rough but now it seems to be going well. My 3D Printer sure is jumpy! 😆

fiery idol
crude kettle
#

Check flow rate

fiery idol
#

It was an old model, it actually printed pretty well. I updated Cura recently, testing out another print. Seems to be going a lot slower than before. But I am using different settings because the settings I had before would make the print take too long.

empty sedge
#

So it's likely the extra pressure in the nozzle putting out extra plastic when you slow down to change directions

fiery idol
#

Huh, cool.

#

I use Cura with my Creality CR-10. Just finished another test print. The quality is great, I had it set to the Standard Quality - 0.2mm. Time to see if the hex nuts fit in the cutouts I made.

#

I think my printer bed was not properly leveled, thank you all for the input.

shy kelp
#

i want to print this wall mount: https://www.thingiverse.com/thing:216329 but i'm not sure if is better pla or abs. may someone help me?
is it safe to use this project?

crude kettle
#

How heavy is the monitor

spiral laurel
#

if your printer is performing well and you take care to print in the right orientation I think that would work ok for a 24" monitor. I wouldn't try it with a 50" TV

crude kettle
#

@karmic brook
BTW what happened to the EXTRUDER

karmic brook
#

I'm not entirely clear what happened. It seemed to be printing fine, so I went away for a while to do other things. When I came back, it had knocked the print off the bed and the extruder was encased in this glob of plastic.

crude kettle
#

Nozzle may have been loose

karmic brook
#

Hmm, are there any specs for how tight it should be? I just reassembled it, so it's entirely conceivable I didn't do so correctly.

crude kettle
#

I normally tighten my when I install it and a little more after heating it. The heat expansions can ruin a tighten nozzle

#

That my also explain the bad prints form earlier

karmic brook
#

I'll try tightening it. The test print looked better but (of course) the real print failed.

crude kettle
#

Yeah, in my experiments be for hand a loose nozzle can do small print be ends in horrible mess with bigger jobs. Right now I was trying to do a print that was going to be like 15 hours but, 5 hours in, it looks like the all metal hotend hates every PLA roll I give it. May need to switch to a hotend with the PTFE tube inside all the way through set aside just for PLA filament. The all metal love the PETG though.

karmic brook
#

I haven't worked with PETG yet. I'm tempted to redesign the part to be several smaller prints. I don't have the original design (just the STL), so I'd have to draft the whole thing again, and figure out how to partition it.

crude kettle
#

There are step file here for it including the hotend

karmic brook
#

No, the object I'm trying to print.

empty sedge
#

@karmic brook yes there are specs for how tight the nozzle should be. I doubt you had it too loose

#

you probably didn't heat it up to max temp, then tighten the nozzle again. Probably should take out the PLA before you do this

karmic brook
#

Hmm, 3Nm at 285°C, yeah PLA would burn at that temperature. Happily, I have a miniature torque wrench with a 7mm socket, thanks!

crude kettle
#

hope it prints well

ornate raven
#

@fiery idol Your print looks like the layer starts in the same place each layer. I've seen that on many of my prints. There's supposed to be a place in Cura to change that bot I haven't looked into it. Can you adjust in your slicer where each layer starts?

fiery idol
#

@ornate raven maybe, I'll have to check. My last print came out well, (had a slight bed leveling issue), but overally it looked nice. I am using the latest version of Cura. Well, unless they updated it within the last two weeks.

#

I can't test anything right now. I took apart the control box for my printer. I am try to hack the control board to get more I/O pins. Figured out I can do it through the SPI bus.

ornate raven
#

My Cura is about two weeks old as well. Look for the YT from some in Canada, does a Friday night show. CHEP, I think is his moniker.

#

I'm too scared to delve into my control board. I replaced it once (Ender 3 Pro) to get the one with quite stepper motor drive. Cut out 95% of my noise whiule printing.

fiery idol
#

I need to replace my Creality CR-10 control board, the USB Port is damaged and I have tried repairing it, but I think the circuit board is also danaged.. I was thinking about getting the one from TH3D, but I have not really looked into it.

ornate raven

#

@ornate raven thank you, I will have to take a look into that.

#

You are welcome. @fiery idol

#

@karmic brook can filament be TOO dry?

karmic brook
#

I suspect not, but I'm not an expert. Apparently absorbed water can boil when it's heated and cause random pressure changes.

devout pewter
#

@karmic brook the nozzle should be tightened while the printer is on and heated to around 230-240C. As for filament being too dry, not really. It will probably start absorbing moisture through the air before it gets too dry.

ornate raven
#

Thank you @devout pewter. I'm thinking of putting in a big nozzle and trying to print with some filament that has a lot of carbon in it and keeps plugging up my regular use nozzle. The torquing tip will help.

devout pewter
#

You're welcome. I just changed a hot end (along with nozzle) recently, so I was pretty up to date on the procedures.

ornate raven
#

I used to work in the plastics industry. I've had to learn new nomenclature for the home 3D printing world. Actually not new, just used differently. An "Extruder" for me was a big heated screw chamber that mixed and melted plastic. The "Hot End" was a "Die". But, I'm getting there.

molten sandal
#

@karmic brook Sorry I didn't catch this discussion going on

#

What @devout pewter said was right, you need to hand tighten the nozzle, reverse turn a quarter turn

#

heat the nozzle and then tighten the nozzle up (but don't wear out the threads)

#

The block is usually made of alu and might wear the threads out

karmic brook
#

I think you folks were right, thanks. I heated up the hotend and then tightened the nozzle to 3Nm with a miniature torque wrench. Took almost 3/4 turn, so it was a lot looser at operating temperature than I realized. Then I redid the first layer calibration (I had wondered why it seemed to be varying, this would explain it), and now I'm doing a test print to see if it's behaving better.

crude kettle
#

I learned this lesson several times before. One time at my college I was helping with getting their 3d printer maintained and we have issues with accuracy for months. turns out it was a loss nozzle that was our issue. An issue I over looked

karmic brook
#

Test print went fine for the first couple of hours, just a couple of nits, when I went to check on it again, the nozzle was again encased in a giant blob of plastic and it had knocked the print off the bed. 😦

crude kettle
#

Check to see if the lead screws are loose

karmic brook
#

Which lead screws? The Z axis?

crude kettle
#

Yeah

karmic brook
#

They seem solidly joined to the steppers. Not sure how that would blob up the hotend, but I'm still learning about these beasts.

crude kettle
#

I may have jumped a tangent there. Are you sure the print is being knock off VS the print not sticking

karmic brook
#

It looks like the print and/or head gets blobbed up, then it crashes and yanks the print off the bed.

#

There are a few big blobs of plastic on the print and of course the large one on the hotend.

crude kettle
#

Hmmmm....what temp is the roll rated?

karmic brook
#

220/240

crude kettle
#

Brand?

karmic brook
#

colorFabb

crude kettle
#

I would think that would be fine filament. The wires to the extruder I guess at this point

karmic brook
#

Hmm, there are a bunch of wires to the extruder (stepper, heater, thermister, heatsink fan, print fan, filament sensor)

crude kettle
#

The stepper

karmic brook
#

Hmm, I can see how that could cause it to miss steps, but I don't see how missing steps would make a filament blob (unless retraction totally failed?)

crude kettle
#

What is the job of the filament sensor again? Does it adjust the speed of the filament?

karmic brook
#

No, it just notes whether the filament is present (designed to detect running out or breakage), it has no notion of speed.

#

There was talk of a fancy laser based filament speed sensor but apparently it was impractical, because it was quietly dropped.

crude kettle
#

With the stepper there could be a chance that it is pushing too much filament at one time

karmic brook
#

Hmm, could be. I wonder how to figure out what the extrusion ratio should be.

#

Or perhaps the new nozzle isn't quite the right size, which would give similar problems.

crude kettle
#

Did you update your slicer

karmic brook
#

No, last update was about 3 weeks ago.

molten sandal
#

@karmic brook sorry to hear about the blobs, these are by far the most frustrating problems do you have a picture of the mess this time?

empty sedge
#

@karmic brook Is the shoulder on the nozzle bottoming out on bottom of your heater block? There should be a gap between that shoulder and the heater block so the nozzle seals against the bottom of the heat break

karmic brook
#

I suspect what happened is that I got a blob on the print, which then caught on the silicone sock and pulled it out of position, at which point, the nozzle was extruding into the sock.

crude kettle
#

Ah, just an unfortunate series of events while printing

devout pewter
#

Perhaps the Silicon sock just wasn't on well enough. Also, maybe try printing without if on to see if that helps.

karmic brook
#

I didn't get a picture of the second mess, here are the pieces after I carefully hacked it off the hotend while trying to avoid destroying the thermistor and heater wires.

#

It's a little hard to tell whether the nozzle has a gap or not, but the information that it (more or less) seals to the heatbreak, not the heat block, is good to know.

#

You can see that there's still hardened plastic on top of the heat block, that's going to be annoying to remove. I may have to completely disassemble the hotend again, in which case I'm tempted to just go whole hog with a titanium heatbreak and vanadium nozzle, but I'm also wary of changing too many things at a time.

#

I am planning on giving it a go without the sock for a while, at least until I tame the blobbing problem. I'll have to remember to reduce the fan speed so I don't get the thermal runaway issue without the sock.

#

Huh, it does not like they did much to it. I am adding in some extra features to my CR-10 right now (RGB LED Support, modified the Firmware, built my own LED Driver Circuit, now Assembling everything). Back to the Creality CR-10 V2, it looks like there was a problem that made them add in those front supports. I wonder why they need those.

cunning oyster
#

I'm new to 3D printers. Looking to buy my first one. This looks like way more than I need to get started, honestly, but they did such a nice job talking about it that it made me start looking at them. I don't plan to make anything nearly that tall out of the gate.

I'm open to recommendations in the "My First 3D Printer" category.

fiery idol
#

A fairly popular 3D Printer is the Creality Ender 3. I am not a 3D Printer expert, but they do seem to do a decent job for their price. You can find information on hack and mods people have done to the Ender 3. Prusa makes good 3D Printers for a reasonable price. They can also be upgraded.

cunning oyster
#

Great. Thanks! I'll check them out. I have heard the Prusa name before.

fiery idol
#

I know someone who has one, and they love it. Some parts on the Prusas are 3D Printed, so if there is a issue with a part or there is a better version, you can just print a new one.

cunning oyster
#

Well, that's handy.

fiery idol
#

I have the Creality CR-10, it's a big printer, too big. It's hard to find a spot where I can put it in my room. It's so tall and the control box is separate. It's nice to know though that if I need to print something tall I can do it.

cunning oyster
#

Yeah, that's where I get hung-up. I can't think of a good rationale for a tall printer other than, "...well, what if I want to print something TALL some day? Then I'll be READY!" But the pragmatist in me kicks in and starts questioning the $$ outlay.

fiery idol
#

Yeah, true. I got my printer for Christmas back in 2017. I think we paid $517.00 for it off of Amazon, the nice thing was that is was mostly assembled.

crude kettle
#

It is pretty big, not good for those who lives in small place.

fiery idol
#

Yeah, it's hard to find a good place for it.

karmic brook
#

The Prusa Mini is smaller, more affordable, and easier to assemble (3 pieces) than the Prusa i3, but it's not available quite yet.

cunning oyster
#

I had the idea that the Prusa printers were fairly spendy. Let me rephrase, the Prusa printers are more expensive than I was thinking for an initial printer. Is it worth the investment?

vast girder
#

Related question: Experienced users, how does the initial price of a printer compare to the ongoing costs of operating it? Considering consumables, upgrades, repairs, whatever else, is there a case for one or another being "cheaper in the long run"?

shy kelp
#

I'm just waiting to meet someone in a bar or a coffee shop who tells me about their ten year affair with 3D printing. ;)

fiery idol
#

@vast girder it just depends on the quality of the parts the printer is made with. I have already had to change extruder nozzle once, I have not really done much printing. There is not really a whole lot that can break on a 3D Printer. Replacement parts can be expensive at times and it could eventually cost more than half of what the printer originally cost.

#

Maintenance also plays a large role in how long a printer will last, if you keep everything greased up, don't leave filament in the extruder, etc., then the printer should last for a quite a bit of time.

#

@cunning oyster I have the Prusa MK3S and it's my go-to printer. I definitely think it's worth the extra money, especially if you just want to print and not have to worry about tinkering with it all the time.

cunning oyster
#

Thanks @devout pewter

#

Good feedback. I'll check it out

karmic brook
#

Agree on the Prusa

vast girder
#

So you're saying that tinkering with it all the time isn't the whole point? 😉

crude kettle
#

I got the Ender 3, but that's because I'm cheap. If you have the cash go prusa

karmic brook
#

I have a MPMD for that and the Prusa for when I actually want to print something

crude kettle
#

My current printer set up does petg flawlessly. However tuning setting was a pain. Not to mention the upgrades i did. It was fun though.

small heron
#

I think i have fallen in love with PETG

#

less fails then with ABS

crude kettle
#

What printer do you have?

vast girder
#

@crude kettle Actually I don't mind tinkering. I don't see any way I'll be turning a profit using one. The main thing I'd want out of it is some experience and understanding of how it works and what can go wrong, and how to get decent results I guess. I'm actually leaning towards the Ender-3 because it seems to be a semi-kit.

crude kettle

It is fun to work with. I don't regret buying it.

What's everyone's preferred PLA filament brand? I normally use matterhackers and was gonna buy a roll since it's like $20 for 1 kg right now but I wanted to ask what everyone else uses/recommends

fiery idol
#

I use 3D Solutech. I also have a spool of Hatchbox, it's more expensive and I don't really like it. Only have Three Spools of filament, but the 3D Solutech stuff has not been too bad.

I found like 1/3 of a 1 kg spool of ABS in the trash today 👀

I'm fond of Prusament, but shipping from the Czech republic is expensive. I'm experimenting with colorFabb and eyeing Atomic Filaments.

cunning oyster
#

What about design software? Is there a generally-accepted "best" option?

karmic brook
#

That varies a lot by user. Blender, Fusion 360, and OpenSCAD seem to be popular, they're all good at different things. However, there are dozens of choices out there.

#

If you do a Discord search for a particular package (those I just mentioned, FreeCAD, TinkerCAD, SketchUp, etc.) you can find peoples' comments about them.

Any chance you have an opinion on snow tires, because I am reviewing those, also! 😉

karmic brook
#

My Canadian friends love Nokian Hakkapeliitta snow tires.

#

I'm fond of Goodyear Assurance TripleTred, aside from the goofy spelling and CamelCaps.

cunning oyster
#

Been looking at Bridgestone Blizzak and General Altimax Arctic. Really any snow tire will improve on an all-season. But we digress...

karmic brook
#

Yeah, the TripleTred are all-season, which suits where I live, as we get mostly mud and slush.

fallow ermine

But really tho don't get creo

#

karmic brook

It's DOS-only, so I wouldn't use it anyway.

fallow ermine
#

What's that

karmic brook
#

Creo only runs on DOS/windoze.

fallow ermine
#

#

But beyond that it sucks as a program

forest wyvern
#

@fallow ermine Out of curiosity, did you learn Solidworks before Inventor? I am learning Solidworks right now after being an Inventor Professional and have the same opinion on the CAD softwares you mentioned, just with Solidworks and Inventor switched.

fallow ermine
#

@forest wyvern yeah, I've used solidworks for like 3 years now and I've minimally used inventor (my friend however uses inventor a ton) and even with the minimal experience I have with inventor I still prefer it over the piece of crap they call creo

forest wyvern
#

Neat, I haven't used Creo but I'll take your word on it. It's very humbling going even from Inventor to Solidworks, it is similar enough to make you feel like you should know what is going on but at the same time different enough to make you feel entirely new to CAD 😆

fallow ermine
#

The biggest complaint I have for creo is that if you want to make a cut you can't just make a shape on a plane and select it then click cut. You have to like negatively extrude it 🙄

devout pewter
#

I used to do all my stuff in openSCAD, but moved over to Fusion360 a couple months ago. I can design way faster with Fusion 360.

fallow ermine
#

When your class requires you to use creo so you just design the whole part in solidworks then import to creo 😂

karmic brook
#

I also started with OpenSCAD, now I'm dabbling with Fusion.

turbid hill
#

Don't recall Creo being that much of a pain compared to Solidworks. It's been a few years, though.

forest wyvern
#

@fallow ermine When you say negatively extrude, do you mean use the extrude tool and switch it from extrude mode to cut mode?

karmic brook
#

I assume it's like OpenSCAD, where you "subtract" the extrusion from the original piece.

fallow ermine
#

I honestly don't know man, I try to figure out what tool does what and it takes like 2 minutes of hovering over it with my mouse before a label pops up

turbid hill
#

Creo’s built-in documentation was pretty sparse last time I used it. But with a decent book, it was fine. I got burnt in my previous job by students (and a few faculty) always running down Creo in favor of SolidWorks (which we had no license for aside from donated licenses to vehicle design teams).

#

One thing I appreciated about Creo was that once you made a sketch, it threw all the dimensions required to lock down the sketch right in your face. If the dimensioning scheme looked like crap, you were supposed to fix it. Inventor at least tells you how many are left. Solidworks just color-codes the lines that are unconstrained.

Acetone will not work on PLA

heat and filling compound would work depending on the size of it, but you will loose detail

I just got a 3D printer with a heated bed. This is the first one I have used that has a heated bed. I cannot get the ABS to stick to the bed. Do I need to add something to the bed?

So, I’m definitely upgrading my CR-10S’s board, but I’m undecided on drivers. Recommendations would be appreciated. TMC2208s, 2209s, or something else? Is there accuracy to the widespread reporting that the Z axis and/or extruder are better served by a different model of driver than the X and Y due to skipping problems?

#

For that matter, MKS Gen L, or SKR?

empty sedge
#

I've been able to print ABS on: Kapton tape, PET tape, glue stick on glass, white glue (pva) on glass, and PEI

#

I've had trouble printing ABS on clean glass

#

if you have a taz, the adhesive holding the PEI down doesn't last very long at ABS temperatures and the PEI will bubble up

deft raven
#

@empty sedge Sorry, I got pulled away for a minute. I am not sure what the be is made of. It is a Airwolf3D HD. The software is saying the bed is getting the 115C

empty sedge
#

that's a few years old. It looks like a PCB heater with glass on top, and maybe a pet sheet on the glass (green)

deft raven
#

No pet sheet. I just have the glass

empty sedge
#

if the glass is bare you'll want to spread something on it to stick to. I've diluted white glue with 8 parts water 1 part glue and spread it on so it's a bit cloudy instead of clear

#

you could also use a glue stick when the glass is cold

#

airwolf3d also sells stuff you can spread on

deft raven
#

Got it. I thought the point of a heated bed was you didn't need an adhesive?

empty sedge
#

ABS shrinks too much when it cools to stay stuck to anything that isn't heated

deft raven
#

Got it! I have always used PLA on a normal piece of glass that I spray hairspray on.

empty sedge
#

it's possible to print ABS on clean glass if you get the temps and print speeds just right but you'll have MUCH better luck with some stickier layer to bond to

deft raven
#

Cool. Thanks for your help!

empty sedge
#

at this point, I'd recommend just printing PETG and ignoring abs: there is no smell, it doesn't shrink as much as ABS, and you can use similar prep to PLA

#

don't print PETG or PLA directly on glass. It can stick well enough to pull chips out of the glass

#

also, with wolfbite or dilute elmers glue or glue stick you won't have to re-apply every print

deft raven
#

Ok. I have PLA from our other printers and this printer was donated to us with a bunch of ABS. I will order some PETG and try that.

empty sedge
#

that old airwolf might not be able to print pla with the original buddaschnozzle-clone hotend.

deft raven
#

OK. Thanks. It was donated to us so i'm not out anything if I can't get it to work. It wouldn't even power on when I got it so the fact that I have gotten this far baffles me. I have experience using 3D printers but haven't build one so I was pretty happy when I got it to turn on and move

Thanks for your help with my printing issues. Ended up rebuilding the hotend twice. Now it has the stepless titanium heatbreak and is working reliably again. The base of this giant LED was a 16-hour print and ran just fine (the previous 8 tries all failed within the first 3 hours).

Glade to hear that your printer is working fine.

I too was having printer issues, but I found out my blower fans for part cooling was blowing on the brass nozzle and not the part itself. Works much better now that I printed a new fan mount that angles the air to where is needs to be.

Now make the Giant LED light up!

karmic brook
#

Oh, that's in the cards. I'm thinking of having a fairly bright LED underneath a chunk of acrylic to emulate the LED die, and a gold wire coming from the post to the anvil to emulate the bond wire.

#

The pieces are hollow so I can thread wiring through them. I'm also planning on printing another piece for the leads outside the body, and a chunk of solderless breadboard for it to plug in to (I'll hide the power supply there).

Okay, so, I need some advice if somebody has experience.
I have an ender 3, and the nozzle got clogged because of the fairly common disk-shape-clog issue. After a lot of work I managed to clean out the hot end completely and bought new bowden tube. Now when I'm trying to install it, it turns out the outer diameter of the tube is smaller than stock - and the coupler thing on top of the hot end doesn't grip to it at all. The coupler seems really janky in the first place but I have no idea where to look for more sturdy replacements. I've seen some identical couplers on banggood, but they come with tube anyway. Ideas? Just buy a set of replacement tube from china?

An idea I had was to thicken the outside of the tube with some electrical tape - it shouldn't get too hot since it's at the cold end of the hotend. But it seems... too hacky.

Does anyone have a reccomendation for a good first 3d printer to buy or make? I was looking at making a reprap but wasn't sure which model to get and whether I should get a kit or buy individual parts.

the prusa mini or prusa i3 mk3s

#

the creality machines are popular and cheaper but you'll waste more time tweaking them than a prusa

vernal panther
#

Ok. Thanks for the info

#

@empty sedge How important is it to buy one from prusa? I see clones on aliexpress for about half the cost, but I'd gladly pay the extra money for the real prusa if it was significantly better

empty sedge
#

get the mini from prusa if cost is a huge concern

#

the ones I've seen on aliexpress are missing very important parts like the control board and printed parts, and then once you get it you'll have to deal with every way they cut corners that isn't obvious like not doing a great job on the filament drive gears, linear bearings, screws, or hotend wiring and polishing

#

I could probably get an aliexpress one working, but I don't think it's worth the trouble for a first printer

#

[I've built several prusa i3 from scratch but still bought the official prusa bed, steel sheet and filament gears for upgrading one of my machines because it's so much nicer than the "glass on pcb heater" I had before]

#

[my current home printer is kind of a 12v i3 mk3s, built using an ultimachine einsy (same as mk3s) but 12V (using prusa i3 mk2s bed)]

#

the hackerspace printer is an i3 mk3s and it's been much more reliable than any other printer we had previously. before that we had an ultimaker 2

karmic brook
#

I started with a cheap printer (Monoprice Mini Delta). It does basically work, but it needed a lot of modifications before it would print reliably, and it still has quirks and limitations. After using it for a while, I waited for a sale and picked up the kit version of the Prusa with free shipping, and it's a great printer.

cunning oyster
#

@karmic brook - did you get the Prusa Mini?

karmic brook
#

I got the i3 Mk3S, which was the only one available at the time. It's more of a kit (took me a couple of days to put it together). The Mini looks like a good buy and is apparently just 3 parts to put together, so assembly should go quickly.

cunning oyster
#

Agreed, though their website says they aren't shipping new orders for MINIs until February

karmic brook
#

They also offer a SLA printer, but I don't know as much about those.

#

Yeah, the early Minis got snapped up in a hurry, and I'm guessing they're still ramping up production.

cunning oyster
#

The price point is interesting.

karmic brook
#

I noticed the same thing: there aren't many printers at that price point, there are a lot in the <$450 range, and plenty in the $2000 and up, but not a lot in-between.

cunning oyster
#

Have you seen the Railcore printers? More expensive, but look nice.

karmic brook
#

I haven't looked at those. I'd looked at Flashforge, Creality, Lulzbot, and Taz lines principally.

cunning oyster
#

Sheesh... Way more expensive.

#

Yeah, I have been eyeing the Creality options

#

Then I bought snow tires...

#

Those aren't as much fun

karmic brook
#

A lot of people like them, but they do seem to generally need some tweaking and mods before they work reliably. That's not necessarily a downside, just something to be aware of. I wanted to treat mine as more of an appliance, so a more ready-to-go unit appealed to me (this is also why I was eyeing the even more expensive ones as well).

cunning oyster
#

Understood. Have you ever tinkered around with a SCARA printer?

karmic brook
#

I'd had years of frustration with inkjet printers that always had clogged heads and finally sprung for a dye sublimation printer that's ready to go anytime and doesn't waste massive amounts of ink every time I turn it on. It was such a relief that when I hit frustration with a cheaper 3D printer, I was motivated to get one that wouldn't need too much ongoing effort (and fortunately, I had the means to afford one).

#

The Scara is the one that basically works like an Axidraw?

cunning oyster
#

Nice. That's great. That Prusa you bought comes highly recommended.

#

Yes, I guess so. But I confess I had to look up Axidraw

#

Looks like it though.

Right. It's an interesting approach.

Interesting idea - especially as the robotics industry continues to mature and evolve and get less expensive.

I'm keeping an eye on the Duet printer as well, they seem to have some clever leading edge design going on.

I had never heard of them until I watched a Hackaday video this week about CoreXY, and he did a brief mention.

#

Duet makes the boards, yes?

#

Are they making their own printer?

karmic brook
#

It looks like they're headed that way. I found them from a mention on this page for an improved E3D heatsink https://www.printedsolid.com/products/e3d-beta-threaded-heatsink-1-75mm

cunning oyster
#

Well, then.... That's a good catch.

empty sedge
#

the threaded e3d heatsink is used with a fancy delta printer effector that has a force sensor built into the effector by building the effector out of a PCB

karmic brook

Oh, neat! I had wondered how it was used (while considering printing a mount that would accommodate the heatsink nut for my current hotend).

I have been using "abs juice" for first layer adhesion on a glass bed, but after awhile I end up with a buildup of the stuff and that makes for ugly first layers. Any tips on removing it?

removing it mechanically (fingertip or plastic spudger) takes a long time and risks scratching the glass, and pouring a bunch of acetone over it and into the environment doesn't seem great either.

I'm guessing it's the fixed offset between the dual nozzles, so won't increase on larger prints, but I could well be wrong!

@fallow ermine You could use the search function for "ender 3" and you'll find a lot of comments.

@spring barn What hotend are you using?

I had this when I had retraction issues

My guess is it starts after a layer change (which typically does a retract)

shy kelp
#

Help, I am having problems printing with ABS.

karmic brook
#

What sort of problems? Adhesion? Warping? Clogging? Something else?

karmic brook
#

Hard to tell (the camera isn't focussing on the area of interest), but it looks like a bed adhesion issue. Could be a first layer height issue, a levelling issue, a bed temperature issue, an extrusion temperature issue, or bed prep or simple cold air. ABS often behaves better when printed in an enclosure.

shy kelp
#

Ahh.

#

My bed is at 80C

#

The recommended temp for ABS from the manufacturer is 210C.

#

I tried 230C still the same.

#

@karmic brook

karmic brook
#

80°C is a little cold for ABS, especially in a non-enclosed printer.

#

You can also improve adhesion by making an ABS slurry by dissolving ABS chips in acetone and applying a thin layer of it to the bed.

#

You could also try a brim or raft. This is all assuming the main problem is adhesion, which is just a guess on my part based on squinting at the video and trying to figure out what went wrong first.

shy kelp
#

I'll get a better video of it..

@karmic brook So....I've has this since Saturday it's the ender 3 pro it was a gift, I suck and didn't get it close enough to the surface.

It takes some fiddling to get it dialed in.

shy kelp
#

Yeah....

elder lintel
#

ABS does not make much sense as a printing material anymore, stick with PETG or one of the other high performance filaments...

#

Creality does have a low cost tent-like enclosure for the Ender # now though...

#

boreal wyvern
#

We print our abs at around 270C (probly 10C too high) with a bed temp at 110C. Wu is spot-on with the tent enclosure suggestion. It looks like the abs is cooling too quickly and you have to watch for AC vents blowing on your printer. Abs is pretty nasty and she is right, although you may print petg at 0.5 the speed of abs, it is more durable and probly has less health hazards longterm.

elder lintel
#

Prusa has some really elegant ones that might be adaptable.

karmic brook
#

I thought Prusa recommended buying a particular small table (Lack?) from Ikea, then printing some joining bits, attaching acrylic, and building an enclosure that way.

elder lintel
karmic brook
#

That's the one! It's a clever design.

elder lintel
#

Yeah prusa is so far ahead with stuff like that

shy kelp
#

After hours of messing with my printer, the extruder plate was wobbly, my room was -15 C, it's snowing, the surface wasn't level, didn't have right temps.

The business my family owns uses a lot of boxes so it's cheap and convenient.

@ornate raven Nice.

#

I'm just struggling with my ABS printing.

ornate raven
#

I'm strictly PLA. Were I to do ABS, I think I'd use an enclosed printer. That's what we had at work and it was very good, expensive but very good. For me (so far at least) the PLA has been a great way to break into 3D printing.

shy kelp
#

@ornate raven I need to build an enclosure.

devout pewter
#

Thanks @elder lintel! I'm honored.

#

@shy kelp and @ornate raven, you may want to look into ASA. It's supposed to have a lot of the good properties of ABS without as many bad things like warping. Some people consider it to be ABS 2.0.

shy kelp
#

@devout pewter omg thanks.

#

I'll look into it.

#

So, how is everyone today?

ornate raven
#

@devout pewter does it need a enclosure?

devout pewter
#

@ornate raven, I'm not sure. I have a roll of it, but haven't tried printing with it yet.

#

I would think no, since I've printed plenty in ABS without an enclosure.

I was just watching Thomas Sanladerers' video ab out it. Looks like an enclose isn't required but can improve build strength (if I read him correctly).

I need to do a heat map of my heated bed. One side seems to always curl up no matter what I do to clean and control temperature.

You could move your print in your slicer so it's on a different section.

@devout pewter , yea, I thought of that. I'm gonna try that after this print finishes. I have several silver dollars on hand that I put on the brim to hold it down :-).

#

others, not

devout pewter
#

If bed adhesion is your issue, have you tried putting things on your bed to help? If it's ABS, you could try hairspray (the cheap kind).

ornate raven
#

I did a raft on a fairly larg print and it still warped. Lot of wasted plastic on that one 😦

#

I clean it with alcohol and run fine sandpaper over it. I've got some of the purple glue some have recommended. No benefit to that.

devout pewter
#

Are you running a 12v or 24v system?

#

I used to do lots of ABS printing on a 12v printer and it was just an exercise in frustration.

Nowadays, my printers are 24v and I usually stick with PETG or PLA.

I think my U bolts might be slightly bowed out. One of them was straight up non-functional & I had to use a spare.

#

Probably. You might want a brim so it has good attachment to the platform

blissful marlin
#

Yes got that

#

Do you think it will also work with flexible filament?

#

Or would it collapse

karmic brook
#

Depends on a lot of factors 🙂

blissful marlin
#

only printed flexible filament flat before :S

boreal wyvern
#

I tend to get some wiggle for taller/thinner ninjaflex prints- at the top we get something that looks like underextrusion. When i printed untitled goose the neck and head were rough but didn't fall down.

shy kelp
#

@blissful marlin only one way to find out

blissful marlin
#

looks ok for a start

blissful marlin
blissful marlin
#

unfortunately it shakes quite a bit at the top

#

Can I avoid stringing with flex filament?

shadow mica
#

yes you can

shadow mica
#

@blissful marlin i think you just need to go slower

karmic brook
#

Agreed, I'd try going slower first, then maybe tweak retraction settings.

blissful marlin
#

hmm okay

#

at the moment I am printing at 20mm/s

#

uhm small problem

#

why is it printing the inside too

#

okay seems to be the infill

#

Not sure why it got enabled

blissful marlin
#

is it normal that the flexible filament is oozing out all the time

shy kelp
#

So I had to strip the end of a 3D printer heating element

#

It has like strands of stuff, is there a chance of the insulation being Asbestos?

#

It might also be fiberglass but I am a bit scared

#

I mean that red cable btw

empty sedge
#

The heater cartridge wires are fiberglass insulated

shy kelp
#

Thanks for the information

#

I am a bit relieved now :)

blissful marlin
#

help

#

it seems to print the brim fine

#

and then it goes crazy and drags everything around

karmic brook
#

Goes crazy how? The printhead zooms around, or the brim pops off or what?

blissful marlin
#

I am not quite sure - there are strings appearing and they get dragged around by the nozzle

#

here again in the middle

#

Center should be free, no?

#

and weird is that it worked earlier

wide otter
#

If you're using Cura, there is an option to only print the brim on the outside or print it on both inside and outside.

mighty gull
#

even still, at least from that gcode preview, it should be able to print that inside brim quite easily.

#

What is your first layer speed? Could be going a little too fast?

wide otter
#

Wait, that's not a brim inside. It's doing lines instead of concentric. Looks like it's printing a floor for some reason.

mighty gull
#

hmmm. might be easier to see what's going on with the color coded Gcode preview. There should be an option to set the preview colors to be by line type? brim should be light blue, walls red/green, infill/top/bottom yellow, at least going from memory.

blissful marlin
#

Yes cura

#

This is the STL file

#

Maybe it has the problem - can someone try?

mighty gull
#

I'll give it a shot after work

karmic brook
#

It slices okay with PrusaSlicer (a Slic3r derivative), but there's a hollow cylinder of material inside the mesh. It's also really tiny (perhaps inches vs millimeters?)

blissful marlin
#

Yes there should be a wall if that's what you are saying

karmic brook
#

Then it appears to have sliced properly, there's no top nor bottom lid. I could add a brim.

blissful marlin
#

Weird then maybe it's one of my cura settings?

#

Okay I think it's the model

#

This one I printed earlier

#

same settings

karmic brook
#

Wait, no, it is trying to do infill. Hmm, object shows 3 shells.

wide otter
#

Did you make this design yourself or download it from somewhere?

blissful marlin
#

Made it myself

#

I just exported it again and put into cura

#

now it has no top and bottom

#

but still seems difficult to print

violet needleBOT

#

Someone here good with meshmixer?

mighty gull
#

that's a voronoi pattern. They're typically randomly generated. Not too familiar with meshmixer though.

karmic brook
#

Tried to load filament to test my 2d-to-3d code and it utterly refused to load. Apparently the last time I unloaded filament, instead of coming out, it broke off inside and got wedged inside the PTFE tube. grump

empty sedge
#

I try to pull up on the filament while it's backing out to avoid that or the molten plug getting left behind

#

thankfully the mk3s extruder is slightly easier to disassemble than the non-s

karmic brook
#

The first time I disassembled it, I used the online instructions. By the sixth time, I had come up with my own, much faster approach.

shadow mica
#

lol my monoprice select did the same thing

sullen zinc
#

I just am NOT having luck printing these keycaps for the SICK-68 keyboard. They look OK but don't actually go on the keyswitch. If I break the bottommost part of the stem off, it will, but that usually breaks so much the key is unusable (won't stay on anymore).

#

it seems like a good geometry , the bevel on the foot part should make it go right on, but .. no. I wonder if my cherry-copycat stems are the wrong geometry...?

#

negative horizontal expansion seems like the next thing to try

#

dimensions of the stems do seem comparable to this unattributed image from the internet

karmic brook
#

I had some issues like that modelling servo horns so I could subtract them from objects so I could make things that engaged solidly with them. Even with quality digital calipers, it took a few iterations to get dimensions that would work well.

sullen zinc
#

yeah, in this case what I'm starting with presumably worked for someone else, whose 3d printer may be tuned quite differently than mine...

#

well that print was a fail, stem detached during the print

#

and the support didn't want to remove either

karmic brook
#

Get out the calipers, measure the mount and print, make corrections as necessary? Looks like a tricky print.

sullen zinc
#

"be systematic" is good overall advice isn't it 🙂

#

I disassembled a spare switch and .. the parts I have "fit", I can insert the stem into the printed part. But it's just snug enough that when I try to do it on an assembled switch, it presses the key instead..

karmic brook
#

Erf, that's annoying.

sullen zinc
#

I don't think that measuring anything is going to help, but adjusting it (probably negative HZE in cura) until it works seems viable

#

oh hmmmm that big rectangle at the bottom of the keycap's too big for my keyswitches

#

I wonder if the designer intends it to be broken off (like a brim, except it's really thick) or just has keyswitches with quite different geometry

sullen zinc
#

@karmic brook that's a nice surface finish on your part btw

karmic brook
#

I was pretty pleased with it, especially as it's some weird old filament I was using.

sullen zinc

Hi, does anyone know of something I can use as a resist for dying SLS printed Nylon parts ("Versatile Plastic" from shapeways)?

#

I have two areas close together I'd like to dye different colors

#

I'm hoping I can cover it in Elmer's glue or something but I'm not sure I can get it off without damaging the part

#

Any experience with that Creality Ender 3 Pro? The price seems a bit too good to be true. Related question: What does Adafruit like for quality 3D printing? I'm looking for a possible upgrade to the FlashForge Finder 3D. It would be nice to have a 3D printer that is more reliable. Often we spend too much time tinkering to get it to work.

vast girder
#

@full verge You can use the search widget here to find recent comments on it. Being in the shopping phase myself, my take is that there aren't any real horror stories, but in some ways it's a kit rather than a product and definitely built to a price. People who bought one with reasonable expectations are mostly happy about it.

karmic brook
#

According to the folks at SparkFun, the Taz Pro is very reliable.

boreal wyvern
#

@pale moth I have yet to dye printed nylon, but according to Matterhackers even hairspray might be enough to resist the dye, in which case you could tape mask and then spray it. (https://www.matterhackers.com/articles/how-to-dye-nylon-3d-prints). You might be able to borrow from watercolor painters where they use wax (not removable), "sizing liquid" / "masking fluid" (which might be removable), or potentially rubber cement.

pale moth
#

@boreal wyvern Hey thanks, I'll check that out. I'm guessing that rubber cement has solvents which will hurt the part, but I'm not sure,

boreal wyvern
#

No problem! Good point about the solvent, not sure. chemical resistance is probably dependent on the type of nylon it is (Nylon-6,66,or 12, or PLC). I have heard it is generally pretty resistant. Definitely an instance where sacrificial samples would be important.

pale moth
#

Good thing I remembered to add a couple extras onto the sprue, especially since this was a tiny part & adding more would still have left me under the minimum price.

#

I definitely didn't forget and am now trying to use a tiny sprue as my sacrifical sample.

Hi All - banggood.com has the Creality CR-10 Mini for $239 which seems like a decent price. However, they have the following note:

Notes:

  1. Do not include T-bracket(right side)
  2. The US/AU warehouse do not have the adapter

So...it seems like a part that may be important to putting this thing together? I'm not familiar with this printer - any thoughts?

karmic brook
#

I assume the "adapter" referred to is plug adapter to allow connecting to US/AU mains outlets. Presumably it has an ordinary ISO power connector on the power supply, so most of us probably already have suitable power cords.

cunning oyster
#

Ah... How about the T-Bracket? That's the one that stuck out to me.

cunning oyster
#

Managed to hunt this Q/A down on their site. Figured I'd post it in case anyone else looked at it:

karmic brook
#

Ah, good find. I had no idea about the T-bracket, just had a guess on the US/AU "adapter".

#

The Ender 3 is only $162 right now.

#

At that price, you could buy one and keep it in the glovebox of your car as an emergency back-up printer.

wet falcon

is the ender 3 an OK option for getting started with 3d printing?

karmic brook

It's an ok option if you're comfortable with a little tweaking and tuning before it works repeatably.

i mean as long as its not too insane i dont mind doing some things myself?

ive been hesitant to get into it all, but $162 seems like a really good entry point

silent iron
#

I wonder if there is a way to take the pins for a second extruder to make a spindle cutter to remove excess off of a 3d print with a end mill or something

karmic brook
#

There are some convertible machines were you can swap an extruder head for a carving or laser one.

silent iron
#

What im thinking about is using a regular printing extruder to create the original stock layer by layer as usual but then have a secondary "extruder" that functions as a small end mill to carve the perimeters of the layer for extreme precision as well as removing the need for sanding. The cuts would have to be layer by layer as well in order to reduce the resistance so that the print doesn't disconnect from the print bed.

#

alas there must be some way to do this with marlin

empty sedge
#

why does marlin need to be updated?

silent iron
#

no clue

#

as long as it works im good with it

empty sedge
#

you'd have to modify your slicer to generate the subtractive toolpath but I don't think you'd need to modify marlin unless you needed something like a special tool-change gcode or marlin to control the spindle RPM

fallow ermine

I personally like matterhackers filament, great price for the amount

boreal lava
#

I posted this in a couple of servers, but no one seems to be able to figure this out Maybe someone here will have an idea. Whenever I print something like a cup that has some regular infill, and then a transition to where the walled portion of the cup begins. I get a weird irregularity in the print where the outer wall is slightly wider in the cup portion than the section below where there is infill. This does not show up in the model or gcode. It has happened consistently across all filaments and temps.
Any Ideas?

boreal wyvern
#

@boreal lava We get a less pronounced version of this with ABS at lower temps (230-245C, bed 110C) on our Polyprinters. We were able to reduce it a bit by moving our extruder temp up (270C), but our cooling fan may still need to be fiddled with because it tends to still appear slightly in square corner containers. If your belts are tight, rods greased, steppers centered, and printer is enclosed; you might try printing a sample print that came with your printer (where the optimal settings are dialed in) and see if it is a physical rather than a slicing setting issue. ? What kind of printer do you have?

boreal lava
#

Thanks Sean. I'm using a pretty heavily modified Ender 5. The weird thing about the irregularity is that it just started a couple of months ago. I have printed some of the same files that worked fine before, but now they have that weird line. I think it may be something in Marlin 2.0, but not entirely sure about that.

boreal wyvern
#

Quite the mystery. Can you try using older gcodes or comparing the old and new gcodes for the same files? My first thought is over extrusion or temperature differences, the bottom shrinking at a different rate perhaps. It looks like you have 3+ shells, have to varied infill and shell count? prusa mentions something called "Z-hop distance", it might be something to look at https://www.prusa3d.com/layer-shifting/ Hopefully you won't have to move back to 1.1.9.

boreal lava
#

I've done identical gcode. That print does have three layers. I've tried it with 2 and 4. It's a very weird issue. That "ledge" shows up at the point where the insides change. I have other files with a thicker base, and sure enough there it is at the exact spot where infill ends. I'm up for trying anything at this point.

boreal wyvern
#

Even with the identical gcode! That's intense. at 10:00 he prints a benchy and finds "salmon skin " and some sort of z chatter. the z chatter might be good to rule out too, in addition to playing with the Vz jerk. https://www.youtube.com/watch?v=u0uxK_uRyjQ

#

@boreal lava what if you're just over-extruding?

ornate raven
#

@boreal lava what's your parts cooling fan doing at that stage? Does the gcode have a change in speeds and wall thickness? What slicer are you using?

boreal lava
#

@empty sedge I can't imagine that would be it. My layers look great, and the top layer is generally pretty awesome. If there were extrusion issues, I would expect them to show there as well.

#

@ornate raven I'm using ProsaSlicer now. I've tried cura as well with similar results. The fan runs between 80% to 100% after the second layer. Generally closer to the 80% unless it is bridging. The gcode looks fine. The previews in Slicer don't have the irregularity. And using the same stl files a few months ago didn't include it when printed.

ornate raven
#

@boreal lava , hmmm... I was wondering if maybe cooling effects might be impacting the different density of the layers. When I upgraded Cura to version 4.3 (I think it was 4.3) the print speed of the inner walls was different than the exterior walls by default and I had some issues with warping and shrinking. So I thought maybe...

boreal lava
#

That's entirely possible. I have other prints with 3mm walls, and approximately 70mm diameter that it does the same thing on at a similar transition point higher in the model.

ornate raven
#

OBTW, I use an Ender 3 Pro and PLA

boreal lava
#

I would think at that scale, and with dual fans, it should pretty well mitigate cooling issues, but I am at a loss

#

There's probably some setting in Marlin that got flipped somewhere that is just laughing at me right now.

#

It wouldn't be something in octoprint would it?

boreal lava
#

Update....tried sending the gcode through pronterface to eliminate octoprint as the culprit. Getting the same effect.

boreal lava
#

update #2....sliced it in Cura again, and while the irregularity is still there. It is much less pronounced.

#

Cura printed more slowly, and with concentric infill on the top and bottom layers, so that may be a factor as well

ornate raven
#

@boreal lava in cura (4.4.0) what are your Quality and Shell settings looking like?

#

You might also want to fiddle with the Infill density and pattern.

#

DISCLAIMER, I am by no means an expert or anything like it in Cura, I'm just sharing what I know has helped me.

boreal lava
#

@ornate raven just to update, someone on another server found the problem. Turns out, it was the infill. Switching from rectilinear to either gyroid or honeycomb mostly fixes it. There's still a small line, but much less noticeable.

ornate raven
#

@obtuse galleon , cool. Glad to hear you have a solution.

empty sedge
#

@boreal lava you might also try printing perimeters before infill

edgy steeple
#

@idle crest & @supple stratus have you guys done any mods or additions to your CR10 V2?

#

What's the sale price?

shy kelp
#

@faint comet IMHO, see if the Pro version is in your price range. Either way. The E3 is a good starter printer.

#

And beware. There are some " to good to be true" sales out there that I would be very suspicious of.

boreal lava
#

Just looked up the sale. It is about $40-$50 off on the creality site based on amazon prices. That's a good price, but given my experience with Creality customer support...I don't know if I would buy from them directly again. They are super quick to respond, and fix things. but lead time is about 3 weeks for a replacement. My first replacement was the wrong fan. The second arrived as an empty envelope. The third finally arrived with the correct item, but I had to sign for it. The delivery guy looked at me weird when I opened the package before I signed.

They're good printers, don't get me wrong, but it's information worth having.

TLDR; It took me over two months to get a replacement for a bad fan from Creality.

#

I upgraded my ender 5 from stock extruder to dual gear because the stock one cracked.

#

SO I'm over here doing esteps calibration

#

started at 92.6 (factory). I measured it, extruded 100mm. It was 17.4 short. So maths == new esteps == 111.97 aka 112.0

#

so i extruded another 100mm

#

it extruded 80.00mm

#

-_-

#

I did a whoopsie?

#

maybe the ender only decided to push 80.000000?

#

it was upsetting how accurately it was off by 20mm

#

i'm printing a test print now it looks... honestly, it looks perfect.

boreal lava
#

that's not a huge deal.

#

you're good

rustic pine
#

gave it another wack, maths came to 135

#

so i'm trying that now

boreal lava
#

so, you expected 100 mm, and got 80. So, (100/80) * steps = new steps

#

I would start by looking up the recommended settings of the extruder. It should get you very close. Then apply the formula of (expected mm/actual mm) * steps

rustic pine
#

@boreal lava I didn't even consider they'd have recommended settings. derp.

anyone know what is used for the whitish translucent parts like swords, etc that @supple stratus and @idle crest use in their projects.. the ones that need to let leds to show thru?

willow sedge
#

@edgy steeple I assume translucent filament. We printed a star for the tree using translucent filament. We had two, one more clear than the other (the clearer one is more expensive). The less clear one looks a little yellower on the spool, but comes out whiteish looking, and LEDs show through quite well.

karmic brook
#

I've used white and clear filament for the flame pendant, they both print as reasonably translucent. I also used white for a lithophane and it came out pretty well.

empty sedge
edgy steeple
#

that is really cool @empty sedge . Great idea to actually show how they would look

edgy steeple
#

I like the difuse feel of the eSun PLA ...but now to figure out which one it is

boreal lava
#

@edgy steeple i suppose it depends on the design. If it can be printed in vase mode, then really any single wall print will work.

edgy steeple
boreal lava
#

that looks awesome! The hardest part of that will be setting up the LEDs

warm palm
#

Woah cool!

boreal lava
#

but as far as filament goes, white or transparent will work

#

I would probably go with white just because it will diffuse the light a bit more

#

I think that photo may be an acrylic box.....but not sure

edgy steeple
#

would have to buy 5 of them.. so I am back to how to getting the perfect pla to difuse but to not overly strangle the light

#

idealy I would also be able to use the same PLA for @supple stratus and @idle crest projects that need some.. like their glowing swords, etc

boreal lava
#

You can't. Using those will be enormously expensive, but also give serious layer lines as the levels go up

karmic brook
#

It might be worth just using purpose-made diffusion material

boreal lava
#

That would be nice as a base....and could work, but if you want variations in the vertical layers, it would not be optimal

edgy steeple
#

I'm not understanding the "variations in the vertical layers"

boreal lava
#

@edgy steeple You could set that as a base, and it would work....but going up, it would not have the same pixelation I think you would want. So you would have to stack them...that becomes expensive, but also gives some very distinct shadows

#

@karmic brook velum is super under rated as a diffuse material.

#

it's pretty cheap, and works well

edgy steeple
#

I feel like a small kid that wants to be an astranaught but no clue what that even means 🙂

#

luckily my infinity cube is close to completion. and my first led project will be done

#

Pay me no mind. I think we all speak from our own experience. You need your experience. Build your thing. Then refine it. The best part of making things is finding out "holy crap, that worked". The second best is when it doesn't work, but you see why

I'm an odd person.. I have a 3d printer(creality CR-10 V2) still in the box unopened.. worried will I use it enought.. will I have enought worth printing out.. will I even figure out how to make it work ok.. they are so much more complicated than people make them seem.. the people on youtube have been using them for years.

If you put that much thought into it, and you are making things....yes; put it together and use it.

#

PLEASE do

boreal lava
#

Go through several assembly youtube videos. More importantly, take your time and make sure things are square

It will add an hour or so to the assembly, but it is well worth it

measure twice and cut once kind of thing

Heyyo, I have an extremely noobish 3D printing question 😅

It's like... 35-40° here (100°F ish I think) and I don't have aircon, are printers okay to operate in that environment? I read something about moving power supplies outside of enclosed chambers but not sure if heat is the reason 😅

spiral laurel
#

think of it as a REALLY BIG heated build chamber 🙂 The power supply and stepper driver chips might start getting cranky at those temperatures

warm palm
#

Yeah I might hold off then, little brother being cranky about waiting a day for prints might be better than harming the printer ^°^

#

Thanks!

spiral laurel
#

if you can get a fan blowing over the PSU & driver board without blowing over the print area you'll probably be fine.

warm palm
#

Ahh yeah I might look into getting a little fan for that

#

Weather this time of year is WILD and it'd kinda suck to not be able to print for a few months at a time because of ambient temperature haha

molten sandal
#

I don't think it would be an issue

#

I live in the tropics and we have ambient 24-35-ish temperatures. As @spiral laurel mentioned, the main problem would be getting cooling to your driver boards and extruder assembly

#

It would be a problem if it gets humid or you are printing weather sensitive materials like ABS

wide otter

I missed the transparent printing discussion earlier, but I've researched it a lot recently and it looks like Polyclear is the easiest way to get a clear print: https://www.youtube.com/watch?v=92C10-n21Po

In this video, I test out a way to make your 3D prints completely clear. Not translucent - but actually transparent.

Ever since I got my 3D printer, I have been wondering whether it was possible to produce transparent parts. While there are plenty of transparent filaments sold on the market, they typically do not produce transparent prints, but rather translucent ones. The difference betwee...

@wide otter : Any finds for translucent ? I'm trying to diffuse neopixels.. so enough opaqueness to hide the led, but translucent enough to not restrict the light too much. Like @supple stratus and @crystal ravine do on a lot of their projects. They seem to use some kind of white.

#

You could just print it fairly thin in white. Or maybe use clear and scuff it up evenly with fine sandpaper?

edgy steeple
#

interesting idea on the scuffing

#

If you need a flat diffuser, I find commercially available plastic diffuser material works well. For other shapes, something 3D printable is probably a good bet. I've had good luck with thin layers of transparent filament (like the flame pendant)

Can anyone recommend a decent site for Creality-specific parts and upgrades that isn't Tiny Machines (which I know and like) or TH3D (which I know and... less said there the better).

It's not exactly a 3d printing question because they came out great, but the bluefruit and tft don't really fit right

#

There's a screw in the way of one of the posts to fit into the board from the tft gizmo and I couldn't find any clear instructions for putting it in the case so figured I'd ask here. Any suggestions or advice is appreciated

#

it looks like the parts differ depending on whether you have e-ink or TFT, and also you omit 4 of the screws when assembling the gizmo to the circuit playground

#

Place the Circuit Playground Express over the standoffs with the USB port lined up with the USB label. The PCBs are secured with M3 x 6mm machine screws (included with the E-Ink Gizmo). In order for the Gizmo and CPX to fit the 3D printed ornament, use only 10 screws. Reference the photo for the correct placement of screws.

#

emphasis on "use only 10 screws"

half yarrow
#

Oh wow, I didn't see that. I had tried removing just the two screws that interfered and then the tft wouldn't come on. Ended up printing two of the backs and just clipping off the posts. I'll give this a shot next, thanks so much!

sullen zinc
#

make sure you have the right parts for your screen, too -- it looks like each one is specific to the display, I guess they interact with the bluefruit using different pins or something

#

Mine are the ones from the December adabox. Probably why I missed this guide. I was using the ones that were listed in the adabox page, but that comes with the clear plastic globe for it

#

I didn't like the plastic globe because of how much it'd move around in it

#

Yeah I don't think it would work for mine

half yarrow
#

I just have to keep the Vout screw in since the code I'm using is the "snow globe" ornament

#

so on my backup I only snipped one post and now it's perfect

Is there any global shortage of PLA?

onyx nova
#

getting the raw pellets of PLA is running into a shortage issue, yes, someone correct me if im wrong, it was because many companies realized PLA is a better bio friendly substance, so now many more things are being made from that, and pulling away from PET. since so few PLA pellet masking companies exist, 3D filament making is getting less to make their product, some companies have actually closed up shop apparently because they only made PLA, and had no diverse setup for other materials. thats the short version.

#

if anyone has any info or hands on with the "super cheap" EZT3D-T1 delta printer, and would like to have input on a better replacement controller board, please let me know. im shooting for the MKS Gen L 1.4, putting in a BLtouch or an inductive sensor. and the knob screen compatible with the MKS.

I got the Monoprice Maker Select Plus 3D Printer for christmas this year and it is my first 3d printer. The issue is with the nozzle not heating up when i preheat it. The base plate heats up fine but the nozzle doesn't. I tried heating it up with a blow drier to see if it was the thermostat that told me it was 0 Celsius even if it was heating up and it still stayed at 0.

#

and i have this problem

sounds like the thermistor cable came unplugged, or maybe the thermistor itself broke in shipping

rough marlin
#

where is the thermistor cable so i can try to attach

spiral laurel
#

since you're X-stop doesn't appear to be registering that thin-wide ribbon seems like a likely culprit. It looks like they have all of their connections running over that

rough marlin

should i just try to push it in more?

spiral laurel

yeah. I was looking in the manual to try and see where the other end plugs in but haven't found it yet

ill see what i can do on my own while you look in the manual

I think I found the problem

if that end was unplugged I think it would account for your issues

I'm trying to print this in vase mode and the printer keeps doing weird moves on some but not all layers. It'll either skip extruding for a little bit or pause, move back, and then continue. I sliced it in Cura 4.4.1. Anyone have any ideas?

Any tips on places to get parts and upgrades for Creality machines? I’m familiar with Tiny Machines and TH3D.

I realize I’ve asked that before, but I’m never sure whether to read a lack of responses as folks not having an answer or as folks just not happening to see the question.

What brand of filament do y'all use?

atomic and hatchbox PLA. I've had bad luck with super cheap stuff

I've used hatchbox pla for all of my printing

I use PrimaValue pla

#

Note: there are good filament producers in various parts of the world, and shipping can be a significant fraction of the cost, so people in Europe will tend to use different providers from people in North America, for instance. I love Prusament, but shipping from the Czech Republic is pretty expensive.

Mostly Hatchbox here.

@onyx nova posted an explanation here a couple of weeks back explaining that PLA is getting used by industry more, competing with 3D printing for raw materials.

ok, here is the fun question.
friend got me and EZT3D-T1 delta for sport after upgrading his ender3. the mainboard is trash and ZERO support or datasheets, and the steppers stutter once the old board drivers warm up, so i am upgrading the board to a BTT 1.4 with tft24-v1.1 screen, and TMC2209-v1.2. has anyone ever done something like this, or have exp with those boards, so i can double-check my new setup.

I have used btts Skr 1.3, and their TFT 24 before, I have never touched a delta though, or 2209s...

I'd recommend you flash btts new firmware to the TFT, its much better than the one they give stock and allows you to switch modes easily. Also, the display to enable in marlin configs for it is "rep rap discount full graphics smart controller" iirc

What well your prints look like when you need to replace your nosle

ornate raven
#

@faint comet I think that varies depending on what happened to the nozzle. I had one that got clogged with carbon. It wouldn't come out without marking up the inside of the nozzle. The prints started getting an unfilled and stringy look. Whole lines were missing and the walls got very thin. I actually thought it was my extruder at first. Then I saw a piece of black something go into the Borden tube a few minutes later the print started missing a layer. That's when I stopped and investigated the nozzle and found I couldn't put my cleaning needle into the nozzle anymore.

in the today's "Adafruit Daily - 3D Printing" they show a collapsing wand.. very cool. It would probably be trivial to add a single rbg led to the end of the wand like https://www.adafruit.com/product/159

#

wire it back to the prop feather.. and change color based on accelerometer.. and some sounds.. any harry potter fans would go nuts 🙂

#

use some silicone covered stranded wire.. that should move easily as the wand is extended or retracted.

@edgy steeple nice idea

#

Hello fellow 3D printing enthusiasts! I got a CR10 V2 for x-mars so I will doubtless be hanging here more often! I'm currently playing first layer whodunnit, trying to find a fix for some adhesion issues. Turns out BL Touch isn't a panacea.

My money is on me still not having the z-height offset/ first layer height quite perfect but who knows? This is the current torture test:

#

This is all new to me, so for all I know that's like trying to hit a 2 meter exhaust port in a T-16

karmic brook
#

Yes, could be bed heat, bed material, first layer height, extrusion temperature, or some combination. I've found hair spray is a hacky but effective approach to adhesion issues. For first layer height, I use filament with a contrasting color to my bed and a cheap pocket microscope like https://www.homesciencetools.com/product/pocket-microscope-100x/ to judge whether the profile is the correct sort of flattened oval, while jogging Z in increments of .02mm or so.

molten sandal
#

I use 3mm borosilicate glass sandwiched by a thermal transfer media

#

Don't use any binder clips as they will warp even 4mm glass

#

I know some folks have success with hairspray, but I found that you could print on bare borosilicate glass with the right bed temps and z-layer height calibration (always)

#

If you are going the hairspray route, you'd need a certain hairspray as well, like aquanet, I used a sticky one and it formed a gucky layer after a week.

edgy steeple
#

@brave mica I also got a CR10 V2 for Christmas

brave mica
#

@edgy steeple nice! we should start a club 😆

edgy steeple
#

I did a 20mm calibration cube.. and my z height is 20.07mm ! but my first layer did a Elephant foot and is 20.45.. then it goes to 20.25mm

#

I found some articles to help with accurate dimensionality so I am going to give them a try and see if I can get a little more out of it.

#

@idle crest also got a CR10 V2 🙂

@karmic brook that filament /microscope tip is a great idea! I'll have to buy some decent white filament; got the microscope already for board inspection

#

@edgy steeple oh yea? nice! I hemmed and hawed past all the sales as far as I can tell. Got mine from amazon for ~$520 though I unintentionally bought it from a non-Creality seller; Had some issues; scratches on the screen, missing z limit switch screws, and an apparently bent thing-that-attaches-the-bed-to-the-x-carriage. Nothing that a hammer can't fix and they gave me $50 back 🤷‍♀️

#

I have some fairly crappy white filament I use for bed levelling, as it's just a throwaway and I'm just looking at the head height, not extrusion quality.

There are some good drawings and explanations, but a dearth of useful actual photographs

One big advantage of a small handheld microscope is the ability to look at things at an angle, which is very useful.
