mm? thou?

#

mil?

fiery pecan
#

0.3 of a millimeter yes for milling 😃

versed wren
#

so about 12 thou, that's going to be tough to mill without binding

#

you might be able to use a drag knife, but that will throw a lot of accuracy out the window

#

the forces will be a lot higher with tin, you'd want to make something a lot shorter, and maybe have a roller platform to resist tilting

fiery pecan
#

12? I want to cut 10 x 10 cm cheets, and I aim for detail.

fiery pecan
#

@versed wren what did you mean by 12?

#

And what is a roller platform?

versed wren
#

12 thou

fiery pecan
#

ty Geys, so two questions remain for me, what’s a roller platform, and what kind of binding options are there?

coarse ruin
#

0.3mm = ~ 0.012"

#

moving tin on a roller seems like a bad idea as it doesn't like to be flexed a lot.

versed wren
#

the roller platform would move over the tin on a table, the idea being to give the cutter head a tripod to distribute force and relieve the gantry

#

a drag knife cuts exclusively with tool force perpindicular to the spindle axis, while a spinning cutter mitigates much of that torque

#

the roller platform would stand around the spindle and apply a counter torque to support the gantry, reducing force A and B by creating forces perpindicular to the table, resulting in a reduction of Moment A and improving stability of the whole system

#

imagine you had this mounted to the spindle such that if the spindle tries to flex on a plane perpindicular to the gantry axis, one of the wheels will press down into the table

#

it will also to a degree resist flex on a plane parallel with both the gantry and spindle axis, but those are going to be a problem no matter what

#

the problem with cutting such thin tin is that the material doesn't have enough strength to resist being pulled up by the endmill, which would cause it to get dragged into and bind on the endmill. To mill it you would need a downward cutting endmill with a high pressure air clearing system because downward cutting endmills shove chips into the cut instead of clearing them, or you would need to adhere the tin to a sacrificial table somehow; The typical means are to own a vacuum table, or to glue it down. Glue can be a problem to remove and typically doesn't work well on metal

#

No more printing services for me, my brother in law is getting a printer and offered to print anything I need out of petg 😁

coarse ruin
#

@versed wren the primary issue with any cutting accuracy on thin metal is tearout... so very high speed, very sharp tools (all of which are $$$ and wear out quickly). you might notice i been working on related methods for some time. (https://www.thingiverse.com/thing:104678)

#

for hold down i have used frostking tape, as it has just the right level of strength, very thin, doesn't compress, cost effective. But you have to cover the entire area to be cut. It also doesn't gum up the tool much when you go though it into a backer.

coarse ruin
#

flatness of the work piece and work surface... make a big difference in the quality of the result is several ways. Tape and glues don't help with consistancy in the ~.001" range.

karmic brook
#

Cutting detail on thin metal is usually done with a laser, water jet, or plasma cutter.

versed wren
#

yea, but that's expensive

karmic brook
#

Laser and water jet is expensive (less so with the Wazer but still). Plasma heads can be fairly cheap.

coarse ruin
#

@karmic brook yes, laser being the best for accuracy in many cases, plasma being the worst. Plasma is generally the least costly and waterjet the most expensive.

karmic brook
#

For material that thin, you can also consider photoetching.

coarse ruin
#

you can figure it out by getting quotes from big blue saw

night kraken
#

:>

coarse ruin
#

yeah.... i did that some time ago with my little roland CNC.... so yes somethings can be engraved / cut that way... but not (most) metal. Metal needs x100 the power of one of those modules to even start with.

#

also it dumb to have a laser of this power in the open with no guards as even a brief reflected beam can cause blindness.

Just got my new printer setup and tested. I am looking for a good intro level CAD software package to create new pieces. Any recommendations? Thanks in advance.

gaunt shoal
#

@slate adder I would check out SketchUp for "entry level", but my go to recently has been FreeCAD.

#

IIRC, fusion360 has a community edition that's free

coarse ruin
#

but fusion360 isn't very "entry" level.... depends on yo skilz

neither is FreeCAD lol

Trying out some new PLA filament from Adaftuit today.

fiery idol
#

Tinker CAD is okay, that was my first CAD software. Now I use OnShape.

cobalt quarry
#

@supple stratus Just watched your snap fit tutorial. Enlightening.

#

@supple stratus Now to make it work on my project (which is a round enclosure).

violet needleBOT

#

I must say, the new filament from Adafruit is working perfectly. No bed adhesion issues 5 relatively large prints in.

coarse ruin
#

@cobalt quarry I've had some strange PLA adhesion issues after using the (PLA/PHA print in Z at adafruit ) on buildtak. Never have figured it out... just goes away after a bit of use /cleaning. I've had worse issues with HIPS and PLA, also never figure that one out, just stopped using HIPS (gave it away).

#

textured surfaces (buildtak) or PEI... has made a big difference to eliminate adhesion issue for my printers.

cobalt quarry
#

I'm using the smooth springsteel heated Prusa bed. I've had ongoing minor adhesion issues. Less over time as I figure things out. I think switching to this new filament coincides with more rigerous bed cleaning habits.

coarse ruin
#

Yeah, i have the PEI coated spring steal heated plate on the PRUSA i3. So far the only failures it has for adhesion have been when oil contamination happened. It's open so that happens a lot. I need to build a box for it.

#

on the buildtak plate the same oil contamination happens... just much less often (enclosed Rep2).

#

oil contamination = smoke, cooking, touching.

#

IPA cleaning or soap and water = fixed.

cobalt quarry
#

@supple stratus Yay! I found your circular snap fit tutorial!

cobalt quarry
#

@supple stratus Alas, I can't seem to get it to project from the inner surface. It always uses the outside surface.

supple stratus
#

@cobalt quarry nice, happy to help! that circle one might be a little tricky. Can't remember which method I used in that but the dice roller project uses it a lot.

#

I've been having a problem with my monoprice maker select recently. Only when printing using Cura (I tried Octoprint and Astroprint for a while but had to use my pi for something else), my printer will act strange. There are two types of things it will do when printing the first layer. 1. The nozzle will seemingly randomly go to edge of the bed and back and 2. when the printer is printing a corner it will slow down and retract and then extrude the filament for a second or so each. The first doesn't fail the print at all, but the second will cause the print to fail on the first layer if I have corners, as it will sometimes move the filament past the gears making the filament pop out of the top. Does anyone know what's wrong and what can be done to fix it?

cobalt quarry
#

@supple stratus I think I got it. Printing the first part now. Once the second is done, I’ll find out.

jolly silo
#

Update: I got past the first layer on a print and learned that the print head will randomly go to the sides of the build plate on all layers, not just the first.

coarse ruin
#

problem #1 sounds like a bad slice / bad model. Have you tried a test print?

#

problem #2 sounds like possibly a bad SDcard...

jolly silo
#

I'm not using an SD Card. The port doesn't work on my printer (probably should figure that one out...)

#

Every print I use does it @coarse ruin

#

Except I just figured out that it doesn't happened if I save the file as gcode and then load the gcode into cura and print from there

coarse ruin
#

so some connectivity issue with the usb.

#

SD card or print server is useful for long prints where having a computer connected for long time isn't useful.

jolly silo
#

I don't think it's with the USB. It works if I export to gcode and then print over USB @coarse ruin

coarse ruin
#

connectivity includes drivers and software... in this case very likely something is messing with the messages on the PC side.

molten saffron
#

@jolly silo export gcode, load into cura and then print?

#

oh I see you said that earlier

coarse ruin
#

^ very likely there is something else running and messing with the port

#

or the printer firmware has bugs with handling the usb.

molten saffron
#

I was thinking flow control because of my experience with Repetier Host but if they can run an exported file fine...I dont know

#

I would recommend getting a Pi Zero and going back to Octoprint or Astro with the shortest USB cable you can get

cobalt quarry
#

@supple stratus Snap fit worked perfectly.

molten saffron
#

started print, nothing coming out, extruder going backwards...

#

no idea how I managed that

#

I need a 24v PSU, 600 watt, 5v standby and ps on support

#

@supple stratus and @idle crest if you're working on a housing for the MPRLS port, let me know so we don't overlap

glad loom
#

Anybody have a buildtak setup? Considering it for the tevo tarántula but the website isn’t very specific.

coarse ruin
#

i use buildtak on my Rep2's

#

i use PEI on my Prusa... both work well.

#

find a sheet that is about the size you need or slightly larger....

#

The surfaces do eventually wear out but should last a long time.

#

They must be kept clean (washing or alchohol wipe).

coarse ruin
#

PEI requires heated build plate, Buildtak does not. PEI is supposed to work with all materials, buildtak works with PLA and PETG.

#

buildtak probably works with other materials when you have heated build plate

glad loom
#

@coarse ruin I’m curious what the buildtak is comprised of? Does it transfer the heat from the heated bed well?

violet needleBOT
coarse ruin
#

@glad loom I would guess some kind of textured vinyl with additives. I made the mistake of trying to clean it with acetone and it partly desolved. It does ok with the heat... most things do ok with heat transfer at moderate temps that don't involve gases.

glad loom
#

@coarse ruin any preference of the buildtak vs PEI for a cheap kit like the Tevo? I appreciate the help

coarse ruin
#

@glad loom they have a 5 pack for 45$ 203mm sqr, unless you print a lot this would last YEARs of PLA type printing.

#

i would say IF you are going to materials other than PLA... get a PEI kit from someone you can trust... other wise PLA / PTEG mostly get the buildtak

#

they list it works with the other materials... and it probably does... but i don't have personal exp with that....

#

either one of them is 10x better than blue tape...

#

makers muse did a vid on how to clean them...

#

@idle crest have you guys done a survey of your printer farm / video of what is the best practice for build plate adhesion?

#

i have less than 5K hours of run time on my Rep2's most of which is buildtak. only ~ 100 hours on my PRUSA MK3 i3 with PEI.

TAZ dual print head arrives tomorrow. I couldn't delay any more 😃

pseudo tide
#

is 287 USD for a creality ender 3 a reasonable price?

#

Including shipping from china

#

I've been eyeing it for so long

crude kettle
#

I would say the reguare Ender 3 works. The magnetic build plate on the Ender 3 pro(what you are proproble looking at) seems like it would go down eventually. Magnetism is lost because of heat and over time..............yeah. I been using glass on mine and AS LONG as I wiped it down with a wet cloth the first time prints stick and pops off once it cools down. For ABS I heard fogging (sanding the glass) helps.
@pseudo tide

pseudo tide
#

@crude kettle thanks! It's actually just the standard model

#

Shipping is about 100$

#

from China

#

To South America.

crude kettle
#

......What website are you using? I used gearbest. Then again I'm in North America @pseudo tide

pseudo tide
#

yep.

#

Gearbest.

crude kettle
#

hmmm.... is there different shipping option on their site or is it the import that happening.

#

@pseudo tide

pseudo tide
#

I live in colombia

#

it's the shipping from china

#

that costs that much

#

plus customs and all

shy kelp
#

@pseudo tide i don’t recommend gear best

pseudo tide
#

why's that?

shy kelp
#

Well, for starters there were many peoples ordered taht have taken months just to process and there coustomer support is more than terrible

#

I would go with Banggood or aliexpress

pseudo tide
#

I think I might go with aliexpress best

#

honestly

shy kelp
#

If you order from Banggood you can also ask Rudy ( worker for Banggood...on his discord server) and he can give a coupon code

#

If you would like i can PM you an invite to Rudy’s coupon-asking discord

(He is a verified worker, the 3d printer discord and electronocity server has him as a “verified vendor”)

pseudo tide
#

I mean, I don't have 300$ on me to drop on a printer right now. But sure, go ahead

#

I might actually order one soon enough

how long does it take for you guys to get it from Gearbest?

#

It takes 4 weeks for me until it arrives

#

@pseudo tide

pseudo tide
#

no idea. Never ordered from them.

night kraken
#

ooh 😛

stray spruce
#

@pseudo tide I also have ordered an Ender 3 :)

#

Yes, GearBest is not my favorite, I never order anything there.

#

Well, since you just ordered there I don’t want to make you feel nervous. I just trust BangGood more. Good luck.

#

Lots of yourubers get printers from GearBest

#

Look at what I am working on! Designing a kossel 3D printer lol.

Don’t know what that is but I’ll say, cool!

sonic plinth

This is a kossel.

@stray spruce

stray spruce
#

Ah

#

I don’t really like deltas

sonic plinth
#

Yep it is the bottom plastic part of the frame you are seeing there. Never used one lol.

stray spruce
#

Circles are really inefficient

sonic plinth
#

Probably.

stray spruce
#

So you are designing and making or just designing for fun?

sonic plinth
#

Both.

stray spruce
#

That’s logical....should have made that an option

sonic plinth
#

Gonna see if this could be something worth making for other people.

#

I am in the middle of a 20 hour 3D print.

stray spruce
#

Just kidding, probably trash

sonic plinth
#

No way. That is a terrible way to go.

#

Oh lol.

stray spruce
#

Ender 3 is like 80 more

#

And 200% better

sonic plinth
#

Yep lol.

stray spruce
#

Ok well, good luck

sonic plinth
#

Thanks!

fiery idol
#

@sonic plinth did you design that part in OnShape?

crude kettle
#

Yeah, Gearbest was not the best in shipping time. And two or three weeks I got it the price went down by 10 or 15 dollars. if you can get it on another site the has better shipping it would be good. Though I can't complain too much, other than their shipping time, they replaced my board that became faulty for free.

Is there a way to get access to solidworks without paying out the actual behind? Just trying to beef up the CAD part of my resume... I would love to have a snoop around inside the software and eventually properly learn how to use it

what's the control software people use these days?

#

i have an old i3v printer

warped hemlock
#

So I think I am going to try out wire printing to see if I can use it to test size solids before I go ahead with 3+ hour prints

eager juniper
#

@worn mason control software? Like a slicer? Cura is pretty widely used, though a handful of people prefer to use a combo of Repetier/Slic3r (though I can’t stand that). Since I primarily work with Flashforge and QIDI Tech machines, I use Flashprint, and I’m pretty satisfied with it for most of my printing tasks.

worn mason
#

@eager juniper software for controling, not slicing. like pronterface or octoprint

eager juniper
#

Oh, don’t Repetier and Cura also do that?

#

Octoprint is commonly used too I know that

crude kettle
#

Yeah, cura has joggling in the new version @worn mason

Why are 3d printers soooooooooo musical while printing????

crisp wagon
#

they like to whistle while they work

serene laurel
#

ive noticed. its great

serene laurel
#

I want to know everyone's favorite print to make! preferably smaller stuff

coarse ruin
#

no favorite... printing is best when it is a one off... but of late i have been mass printing snow flakes and snowmen prepin' for nashua nh holiday stroll / winter fest.

#

and strechlets as test prints...

versed wren
#

because, and I think this is great, sound is just the concept of things repeating at a pace

#

steppers step, but to do useful things most of the time they have to step repeatedly, and they can do so at a given pace, one step doesn't make a tone at all, but move around and suddenly it's a youtube channel reproducing videogame music by moving different directions at varying speeds

coarse ruin
#

not the printers that use the trinamic drivers...

versed wren
#

that is probably not true

#

just about every moving system emits sound, the trick is to make that sound inaudible

#

if you can microstep small enough, and increase the frequency of steps to over about 25kHz, most people won't hear anything at all

coarse ruin
#

the fans are louder than the stepping on the Prusa MK3 i3....

#

i.e. not musical anymore... still sound....

#

same is true for most 3+ axis CNC's... so loud you can't hear the music of the steppers.

tardy fox
#

I've found certain movements on the Prusa MK3 produce a fun series of (subtle) tones...medium to large circular (XY) movements usually do the trick but only at the right speeds 😄

eager juniper
#

The Flashforge Finder at my work is hardly musical at all but my QIDI Tech I is beep boopin all day long... I kind of prefer the musical humming but only time will tell if it gets annoying or stays fun lol

serene laurel
#

question about filaments. If im looking on amazon for filaments what do you recommend looking for and what do you recommend steering away from? It also doesnt have to be amazon specifically.

eager juniper
#

For PLA I like hatchbox, Asani, AIO robotics, Esun, Flashforge...

#

Not much experience with any other filament types other than ultra-flexibles, which you’d need a specific extruder for. Ive heard generally you can’t go wrong with hatchbox filaments

serene laurel
#

My friend said hatchbox and inland

#

said those are typically the 2 better ones

versed wren
#

inland is microcenter's rebadge brand, not to knock it as I haven't tried it, but as with all rebadge brands there's a limited ability to say anything that will remain true

serene laurel
#

ahhhhhhhhhhh ok. so far Inland is working decently for me. but i havent done anything crazy yet.

#

How is proto-pasta? they have sparkly shiny glittery filament and it looks great

tardy fox
#

I've been using Inland's PLA for a while now. it's ok...if you spend some time tweaking your temperatures just a few degrees up or down you can get some nice results. be careful because not every spool of their PLA uses the same temperatures. I have a few spools labeled "190-210" but most others are marked "205-225" and yet a few others marked with temperatures somewhere in between those others. generally speaking I've found the first layer turns out best about ten degrees above the minimum and then I print the other layers at the minimum temp on the label. cooling fan at 100%, of course. YMMV

#

(this is on a Prusa MK3)

serene laurel
#

Interesting. I just recently got my first ever printer. so I dont know everything about them. but I will definitely look into that

tardy fox
#

I'm fairly new to this stuff, too...only had my printer about two months. in any event, honestly the Inland stuff is a great deal if you just want cheap. just be prepared to have to fidget with it a little bit because it's just not very consistent

serene laurel
#

Alright

tardy fox
#

that said, once you get it dialed in and are aware of the temp differences spool-to-spool, it'll turn out well. PLA is pretty easy 😄

#

as you're new to this...one thing to really dial in is the first layer. if that's not right, it'll fall apart on you quick. 😉

#

so pay close attention to that 😄

serene laurel
#

cool beans! at the moment im just printing crap to print hahahahahaha

crisp wagon
#

re-asking from above... on the Crickit Lego rover page they mention .25mm nozzle size. What do I do if I only have .4mm nozzle?

tardy fox
#

yeah that's what I did 😂

#

@crisp wagon unless it's got some crazy detail or something unusual you can probably just change the nozzle size to match what you're using in your slicer app

serene laurel
#

Im printing an articulated feesh right now

crisp wagon
#

it's lego, so size would be a bit sensitive

tardy fox
#

ah yeah, if it's a tiny figure or something, you might have trouble with the larger nozzle

crisp wagon
#

I haven't done any calibration prints to see how close it is

tardy fox
#

honestly I've only printed with the .4 mm one that shipped with the printer so I can't speak to different nozzle sizes much

#

but

#

if it's small, I say try it and see how it works

#

worst case, it's crap and you have to toss it. if it's small, it shouldn't be too much waste

crisp wagon
#

it'd still work as a mounting base, just might not fit legos

tardy fox
#

idk, I bet it'd still work...you just might lose some detail

serene laurel
#

da fudge????? benchy doesnt float

tardy fox
#

lol

crisp wagon
#

page says

    0.25mm nozzle for fine quality
    0.10mm layer height for LEGO studs/tubes
    0.38mm line width / 2 wall line count 
    60mm/s printing speeds

kinda hard to get .38 lines with a .4 nozzle

tardy fox
#

benchy is sort of a demo model..."test your printer" kind of thing. I don't think it's intended to be a usable floating model 😄

crisp wagon
#

but I'll give it a try

serene laurel
#

i know......... but come on...... if youre gonna make a boat.... it should float.....

tardy fox
#

ah, yeah if you have to meet those numbers...might not work. I'd still give it a shot though

crisp wagon
#

a guy on youtube printed a RC boat, first try had to be sealed to keep water out

tardy fox
#

yeah printed objects aren't water-tight. you have to seal them if you want them to be

serene laurel
#

I saw a guy on thingiverse that made a giant benchy and made it remote controlled

tardy fox
#

haha that sounds like a fun project

versed wren
#

they can be

serene laurel
#

lemme find it

versed wren
#

you have to design them to exploit how the printer prints to create a solid hull

serene laurel
versed wren
#

basically, the hull has to go up, if you print it horizontal like the boat will float, a lot of bad stuff happens to create gaps in the hull when going around any kind of curvature, but if you print it vertically then it all stacks really tightly

crisp wagon
#

I've noticed in videos of multicolor prints that they are pretty wasteful of filament

tardy fox
#

yeah, you have to (at very least) purge the extruder of the previous color which results in at least some waste

crisp wagon
#

a tower of waste

tardy fox
#

I've got the Prusa MMU 2.0 due to be shipped late this week or next...they have "wipe to infill" now so that can help reduce the waste if you have an object with any amount of infill

#

idk if you've seen any of their demo videos but it looks pretty sweet

serene laurel
#

My printer is a wanhao i3 plus.

#

i think thats how its spelled

crisp wagon
#

Tevo Tarantula

#

been thinking about getting other nozzle sizes to have available

serene laurel
#

Ok so what about Glow in the dark filaments??? i wanna make something that glows. not just in the green but maybe in another color if possible

tardy fox
#

I've heard most glow-in-the-dark filaments erode the nozzle away

serene laurel
#

realllly???? i just ordered some hatchbox glow in the dark. it had good reviews

tardy fox
#

so your .4 mm nozzle will turn into a 1 mm nozzle 😆

serene laurel
#

da fudge....

tardy fox
#

order a spare nozzle or two. just in case.

#

I honestly don't know for sure, it's just something that another...much more experienced...person told me not too long ago

serene laurel
#

actually, ive got my all metal upgrade kit to install too. so that will be an extra nozzle i gues.

#

I wonder how the amazon basics filament is lol

tardy fox
#

not sure! I want to try it...one of these days 😄

serene laurel
#

between my dad and I we've tried a handful of amazon products, mostly the cables. but hey who knows, it could be worth a shot!

That would be amusing having a camera mounted inside of that to actually watch it to your computer

Does anybody make filament with enough metal in it to print RF wave guides?

#

Trying to get a new spool holder started. but Im not having much luck actually getting it to start.

serene laurel
#

so im having a weird issue with some filament. I have 2 filaments right now. Both are Inland PLA with the same running temps. With my purple filament i was having no feeding issues at all. it feels kinda smooth. I was trying to make something with my blue filament and it started fine but it stopped feeding at some point. I felt my blue filament and its kinda rough feeling. Could that cause feeding issues? because it definitely seems to be having a feeding issue with the blue.
im running a print with the purple right now and theres no issues what so ever

tardy fox
#

@serene laurel I've been using the Inland PLA, too. double-check your temps. some of their PLA has higher/lower temps on it. I've even had a couple cases where the temps on the box do not match what's on the spool -- I go by what's on the spool.

#

most of my spools have 205C as the minimum temp, but at least a couple have 190C as the minimum temp

#

the light blue color I have is slightly more coarse-feeling than some of the other colors

serene laurel
#

See i was going by whats on the spool. but i just noticed that on the blue there is a sticker that is plastered over the original sticker on the box. it says the optimal temp is 215-225 C

#

Which blue is it? I got the Egyptian Blue

#

i finished a print with purple succesfully. So i loaded up blue onto the same print file. but set it to a bit higher temp

tardy fox
#

yeah they have different temperatures for both PLA and PLA+. i’ll send a picture when I get home…I’m on my way there now lol

serene laurel
#

Woooo the print with the blue was mostly successful. it got a bit funky at the end though. but oh well

coarse ruin
#

ordered up some of the amazon filaments..... should be here thrusday (back ordered for a month).

serene laurel
#

Ohhhh please do let us know how they work for you @coarse ruin

tardy fox
coarse ruin
#

as a note about temperatures on filaments... each printer has a slightly different thermal path from the sensor to the actual plastic. It would be very easy to see for a 5C difference. I work with thermal sensors for one of the day jobs. Additionally the different head types will impact thermal transfer also. The end result is a setting that works for one printer will only be close to the setting for another printer.

@tardy fox I dont have any of those blues. I have "Egyptian Blue"

tardy fox
#

you can’t tell in the photo but that middle spool is sort of a translucent blue and it actually looks pretty cool after prints which is probably the only reason I bought it lol

serene laurel
#

lol

tardy fox
#

I have by far the most trouble printing that light blue on the top…it tends to not stick very well to the bed

serene laurel
#

I have white and glow in the dark filaments that are about to arrive in just a little bit hehehe

tardy fox
#

but yeah I saw the Egyptian blue last time I was there and it looked pretty cool 😄

#

nice haha

serene laurel
#

or right now!!!

tardy fox
#

lol yayyyy

serene laurel
#

ok so whats the recommended way of storing filaments when not being used?

#

in the baggies they come in I assume?

tardy fox
#

generally speaking, dry storage is recommended

serene laurel
#

ok.

tardy fox
#

most of the plastics will (slowly) absorb moisture which sort of ruins your ability to print with them

#

some are (much) more sensitive to this than others

#

I hear most nylon goes bad in hours

serene laurel
#

holy fudge

coarse ruin
#

PVA even faster

tardy fox
#

PLA will probably be good for at least a couple of weeks before it spoils.

serene laurel
#

im gonna have to get a new ziplock baggy for one of my spools then

tardy fox
#

honestly I've just been keeping them in the resealable bags with the silica gel packets

serene laurel
#

the spool of hatchbox i got doesnt have a resealable bag! so i gotta get a baggy for it

coarse ruin
#

PLA goes off after a year or so... if not in a dry box. At present count i have ~ 30kg of different PLA colors... so use it up or give it away....

serene laurel
#

geeeez

coarse ruin
#

for the nylon i use a dryer oven to prebake it.

#

and a dry box

tardy fox
#

I mean, the good news is that I don't really care much if the super cheap Inland PLA goes bad. it's just not all that expensive. so far I've been pretty good at using it up so...

#

I've only printed PETG and PLA so far. I'll take a stab at ABS when I finish my enclosure 😄

serene laurel
#

all of my spools are inland. except for the glow in the dark Hatchbox i got today :3

coarse ruin
#

PETG and Nylon have a lot of overlap in use cases. PETG is easier to print. I still haven't printed 1 Kg of either.

tardy fox
#

the spool of PETG I have right now is Inland. it actually seems to print really nicely 😄

#

but yeah I haven't printed much with PETG. the main reason I've used it so far is when I need something that's a little less rigid than PLA

coarse ruin
#

PETG has a lot of nice properties and is much less difficult than most other materials. Tom S's filaween series does the best and talking about it. CNC kitchen does the best at showing and quantifying the difference.

#

less rigid but also has a better "plastic region". I use it for hardwearing mechanical parts that need to take impact. PLA doesn't do well with impact / shock.

tardy fox
#

definitely, yes 😄

coarse ruin
#

one of the best parts i did with nylon was the "rubber" part of a spider motor coupling.

tardy fox
#

I haven't tried anything nylon yet. perhaps someday 😃

serene laurel
#

ughhhhhhhhh my printer just doesnt like this blue filament

tardy fox
#

@serene laurel the Egyptian blue?

serene laurel
#

yeahhhhhhhhhhhh

#

I had it going pretty well. then the nozzle jammed

tardy fox
#

oh it’s jamming in the nozzle?

serene laurel
#

it jammed up in the nozzle.

tardy fox
#

did you try bumping the temp up a little bit? maybe 3-5 degrees?

serene laurel
#

not from the like 220 i was already running it at. but I will go and give that a try real quick

#

Actually, 225 is the max optimal temp of the filament

#

Well im giving it a shot at 224C

tardy fox
#

it's weird that it's getting jammed. I always print mine at the lowest temp on the label and I've never had problems with jamming

#

what kind of mechanism does it have? and is it jamming in the extruder or in the mechanism that feeds it into the extruder?

#

is it a bowden setup?

serene laurel
#

its jamming somehwere in the extruder/heating element

#

bowden setup?

serene laurel
#

ohhhhhhh. nah it doesnt use that. the extruder motor is basically right on the hotend

tardy fox
#

hmmm, what printer is it?

serene laurel
#

Wanhao i3 plus. its the Powerspec version which is micro center's version of it. but its just a wanhao i3 plus with their name on it lol

tardy fox
#

seems weird that it's jamming

#

what happens when it jams? it just stops extruding? is it grinding down the filament with the gears?

serene laurel
#

yeah. ive got the all metal hotend upgrade for it too so i can do the higher temps/

#

And i think it is just grinding down on some of the filament when it jams because it just stops extruding. works just fine for the purple. I'll have to run a print with either my white or the glow in the dark to see if they jam at all

tardy fox
#

it's weird that it only happens with the one color

serene laurel
#

yeah. im about to run the glow in the dark on a test

crisp wagon
#

If I overlap 2 pieces in Cura (or any other slicer), will it print them as one piece as if designed that way or will it try to double print where they overlap?

serene laurel
#

Ok my cura it won't let you overlay 2 things

tardy fox
#

no idea...I've never tried haha

serene laurel
#

Well the glow in the dark seems to be printing much better than the blue

tardy fox
#

maybe I'll pick a spool of that egyptian blue up and see if it gives me any trouble, too 😏

#

although

#

I have

#

so. much. blue. 🤣

serene laurel
#

lol

#

on a good note though, the glow in the dark test print turned out great!!!

#

I held it under a lamp for maybe 30 seconds max.

tardy fox
#

sweet! 😄

crisp wagon
#

tried an overlap in Cura and it didn't complain when I lapped nor when I then sliced

#

(white) LED appears to charge as well or better than incandescent

#

UV would probably be best

coarse ruin
#

the filament might have some material in it that is ~ 0.4mm. I've found paint chips in some spools. But once jammed it usually stays jammed. (under extrude).

#

if it doesn't happen right away... i.e. takes 10's of minutes to jam, it could be pre-melt issues.... i.e. the fan on the heat brake, or to high temp.

#

and lastly... have you checked the diameter.... if it is undersized it might not feed. Check several places on the filament. I've had some spools that clearly got exposed to a lot of heat and made the filament oval.

#

there are several other options but the above are some of the most likely

serene laurel
#

im going to let one of my friends try the filament in his printer as well. see if he has any of those issues. But thank you very much you guys for helping this noob try to figure it out.
@coarse ruin I will probably try some of those things in a bit as well

What size touchscreen do you all use on a raspi running octoprint?

#

or what do you recommend for a screen size. my buddy says to get a 7 inch touchscreen because apparently touchUI is messed up and doesnt work so well with octoprint?? I was looking at getting the HyperPixel display once Adafruit got them back in stock

tardy fox
#

I don't have a touchscreen on my printer. I just use the octoprint UI on whatever computer I have near me 😆

coarse ruin
#

same... Rep2 and Prusa have simple displays. I've been looking for a graphical solution that does not involve much work, reasonable simple UX, not more than 100$ project cost... still haven't found it.

there are 3 main approaches: 1) web + server, so octoprint and a tablet old laptop, 2) direct connect... depends on the printer controller brains as to the solution, 3) other special solutions.

@crisp wagon Tinkercad probably needs a name placeholder to start off a new project in its database. You should be able to double-click the name and change it. I guess it's more interesting than a random string of characters that gets generated.

crisp wagon
#

This is odd... In Tinkercad I make a cone with top radiius of 50 (diameter 100) but when I make a cyllinder 100x100 it is smaller than the top of the cone (and yes, the workplane is set to the top of the cone, so it's not just perspective).

#

What is going on here?

eager juniper

Not sure specifically but tinkercad is pretty garbage in terms of precision design. After my first two designs I switched to Fusion 360 (did the thing to get it for free) and never looked back. Way better for when you need measurements to be on point.

Nice! they look good!

#

Soooooo quick question, ordered some filament not realizing it was ABS. my printer is in my bedroom, is that going to be an issue with ABS? ive never printed it before

coarse ruin
#

ABS is 10x worse for particals given off while printing (studies say).... also it smells like burning styrene (because it is).... it won't kill you... but you won't like it and it won't be good for you... so don't do it often.

#

if you can vent the room (open a window?) it might be ok.

#

note that the printing speeds and material properties of ABS vs. PLA are not even similar. Each has their uses and many parts could be either... but ABS is less than half the strength of PLA, but it is not brittle like PLA. Print speeds of ABS tend to be 2x slower than PLA.

#

For ABS you have to have a heated bed (for larger prints enclosed) to keep the part adhered to the print surface. Otherwise warping and peeling will be an issue.

wicked shard
#

anybody here have any experience printing snap fit joints?

shy kelp
#

@coarse ruin bit of overextrusion, whats ur filament?

#

for ABS you also need al enclosure, however an open frame non-heated bed 3D printer could work with 3S-EEZ and a sticky surface

#

ABS is fine if you have an enclosure

#

ABS can also be printed at up to 100mm/sec, you just need the right extruder.

I have a CTC Formaker 4 in 1 3D Printer. It has worked great for a long while but now it is messing up. It will print fine for awhile and then the filament will stop coming out but the printer keeps moving like it thinks it is still printing. If I clear the print job and start over, it again prints fine at first but then I get the same end results. Please help me fix this problem.

coarse ruin
#

@shy kelp The image is from a prusa i3 MK3 that persistantly has low quality extrude control (over and under) due to a varity of factors.(mostly settings). I've been tweeking and improving it over time (see issue 602). The image is an example of test print with 20$ "amazon" filament no setting change... quality is "ok"

#

I've purchased a few more spools for testing.

#

Whats your slicer?

Have you calibrated extruder esteps?

#

yep

shy kelp
#

coarse ruin
#

p.s. i will also do some testing on my old Makebot Rep2 with this filament when i get time (next week)...

shy kelp
#

Do you have linear advance on?

#

Or coasting?

coarse ruin
#

both

#

coasting is difficult to calibrate because it changes with temp and material.

#

with out coast the is MASSIVE over extrude....

#

i also need to update to cura 3.5

shy kelp
#

Disable any settings that arent critical to getting a finished print

#

Then add 3 or 4 features after every successful print

#

Also i recommend a 0.6mm nozzle, coasting disabled, linear advance on, combing on, and an extremely calibrated extruder

coarse ruin
#

"finished print"? all prints finish... poor word choice. I've been moving step by step for 2 months... I'm not a noob. I've been printing for 7 years now... from back when replicatorG was the interface.

shy kelp
#

I mean any features like coasting or any of curas expermental stuff

coarse ruin
#

also the prints shown are give aways... that i try to crank out at max speed and not my best quality settings.

Prints like that shouldnt be coming off a mk3

yeah the objet is good for very fine detail complex stuff.

Its meant for 100mm/sec with prints better than a mk3

But it has no manual

#

i just canceled the maintance contract on it because.... it was more than the cost of the form2.

#

no thanks...as you can see i already have enough work keeping the ones i have going and 2 other project printers i didn't even mention.

#

the PRusa Mk3 is my "high reliablity" long run, "strange materials" printer...

#

it "can" produce good quality stuff... when you spend the effort on tweeking settings.

#

the Rep2 produces above average stuff... but anything beyond 4 hours and the risk is high that it will fail.

#

I've modified the Rep2 a lot to increase reliablity... out of the box it would fail regularly.

#

p.s. that is from the class i teach

#

will be setting up the CR10 with a 0.6mm nozzle soon

Cracking noise? What type of filament are you extruding?

#

Also for your earlier question does it extrude before you hit “print” or is it during the print, but at a point where it’s not supposed to be printing? (like the very beginning, during a pause or movement to another area, or if you have multiple extruders when the other one is supposed to be printing)

@Luckie12345 🐺 try slightly lowering the extruder temperature and increasing the retraction length and retraction speed. Seems like it may be melting out faster than it can suck it back up when it’s supposed to be waiting or traveling instead of actually extruding.

Hi guys, I have an odd problem, I want to use grbl firmware for cnc positioning of a sensor, but I want to sync the position of the sensor with other data from DAQ, how I go about doing that?

coarse ruin
#

you could time stamp x y position much like is done with xml GPS data.

#

output it to the DAQ as serial data.

#

assuming the data in the DAQ is timestamped you can get both in the same data set.

#

it assumes you will extend grbl with your own code for this process.

#

there are likely several other ways.

strong idol
#

There are discreet positions for the sensor that I will define and move the sensor with gcode, I need those positions onto the DAQ, DAQ only reads voltage.

#

I also want to use grbl controller, so one way of doing this could be writing some predefined voltage values after the g code has run and position is achieved. For this I will need to modify the grbl code? If you know the code part I will need to change, kindly let me know.

#

So as my 3D printer nears it’s shipping date I’m starting to consider filaments. So far I’m planning on trying two spools of PETG filament instead of PLA. Should I start with PLA instead? They have similar properties but I hear PETG is stronger.

Amazon says, “offers the best of both ABS and PLA for a win-win alternative to choosing one or the other.”

#

Also PETG comes in nice colors including translucent.

#

I watched it

#

that is why i was asking for it

coarse ruin
#

so i think the method you could use to fix the warping he experienced is to use a method i use for glass... you pack it in a removeable material that is a powder...

#

the powder supports the thing that is melting...

#

i use silica for glass because the temp range.

#

but at these lower temps maybe just plaster powder would work.

#

tom gave a link to the material he used. but i generally don't think of the filament he uses as an option due to the euro shipping issues.

#

so it looks like proto-pasta is the main source... or at least to use that terminology.

is there some kind of UHMW or teflon filament?

or anything else that's exceptionally good at ignoring chemicals

seems like the big problem is 'molten' UHMW doesn't 'flow', so your extruder needs to be able to apply a very high pressure to move it through the nozzle

I did see some UHMW filament on something like aliexpress, but existing is not proof of suitability

can you just thread an M3 bolt into an appropriately sized 3D printed hole?

i sometimes use heat-forming threads... i.e. metal screw upto 100C, thread it into the plastic.

it works best for smaller threads or fine pitch. If it is a long thread, back the screw out heat up again and repeat.

this is for a little adjustable catch thing, so it would probably contact at two positions with a depth of about 3~4mm each

First time using petg. ive got a heated bed and its covered in painter's tape right now. first test (extruder: 235c, bed: 65c) started to stick fine but separated from the tape after a minute or two. second test (extruder: 240c, bed:75c) it never really stuck to the tape to begin with, it got stuck to the extruder at one point. Am I doing something wrong? should either the extruder or bed be hotter/colder?

serene laurel

my printer. i dont have a glad print bed on it

coarse ruin
#

blue tape is questionalbe at best. printed onto a alum surface will fail most of the time unless it is coated in PVA or something similar.

#

PETG is very much like PLA for adhesion... any oil on the print surface and it won't stick.

#

PVA = clear school glue / glue stick

#

heated bed between 65 and 75 helps most prints adhesion.

What is auto-leveling? I have not had time and $$ to get into 3-D printing yet

fiery idol

Auto leveling is a feature that some 3D printers have that level the print bed. It is called auto bed leveling. This is typically done with a proximity sensor and the bed (I believe) is leveled in the code. (Adjustments of how to print on the unlevel surface are tweaked on the software side to counter the unlevel surface). I could be wrong. Just google it to be sure.

quarternions! the best of all gimbals!

up down left right strange charm

fiery idol
#

Lol, okay.

versed wren
#

now imagine a fourth spatial dimension

#

we'll call it k

fiery idol
#

Can I call it s?

versed wren
#

with a normal 3D gimbal, a system that is able to rotate on N dimensions

#

no s is seconds

fiery idol
#

How about m/s?

versed wren
#

uh... brain, witha normal 3D gimbal, you can rotate around all the spatial dimensions, and rotating around one moves the other two, but no matter what every axis is perpindicular to the plane formed by the other two axis

#

so there are positions you can put the system in where it becomes ambiguous how you would rotate it to get anywhere, and conversely how rotating it any way would result in it being

#

with 4 perpindicular spatial dimensions, this doesn't happen

#

don't imagine it too hard, you'll break spacetime

#

so then a transform is a change in position, say if you move one meter forwards, that's a translation, but a transform doesn't need to be limited to any particular kind of change, you could move a foot in several directions and spin about 5 times before landing on your face

#

if you assume the 3D printer's axis are perpindicular, which probably isn't true but you have to take the assumption, then it doesn't matter what angle the bed is at

#

what you need is the layers of the print to be parallel to the bed, so if you transform the print job to match the table, the print head will move up and down along the table's slope, and everything will work just fine (within limits)

#

imagine you have an object and you're holding it perfectly vertical; and you have a table that isn't perfectly horizontal, when you set it down, the object will transform via gravity to rest on the table. same thing

#

the only down side is that rotation along one axis in a 4 dimensional quarternion doesn't traverse a plane like rotation along one axis in a 3 dimensional cartesian coordinate system

It was a pain to get the light strip in on my printer because my light strips have some sort of rubber or silicone over the LEDs. I had a light strip in before, but I decided to redo the lights so I could have a longer strip in it.

Ooooh, nice! My leds are in the top of my printer. I have not put any on the X axis yet.

I also 3D printed a little status light for my printer.

green pine

oh nice

#

what's that hook into ?

fiery idol
#

The T-Slot in the extrusion.

green pine
#

sorry, I mean electronically

fiery idol
#

The status light and the light strips tie into a mosfet board I made, that is then connected to a Arduino which is send commands from my computer. The computer sends the Arduino commands and the Arduino sets the color of the status light based on the received command.

green pine
#

fair enough

#

love to see a demo

fiery idol
#

I have to use OctoPrint though to get the status of my printer, which means that I have to use my printer over USB to use the signal light.

#

I'll send you a video in a little bit.

I still have to rewire the LEDs, I won't start a print yet, but I can still commands to the lights to get them to do stuff. I might send you a video of the whole system working while something is printing.

cool bad idea, 3D printable 'joystick' with adjustable rubber feet and adjustable finger things, you adjust all the adjustments and sit it on top of your mouse, then a system of linkages transmit 2 triggers down to click the mousebuttons.
for when you use computers too much and need to not hold your forearm pronated that far all the time, without needing to buy a fancy, expensive, and probably not good vertical mouse

#

maybe having it sit next to the mouse with a couple of sliders of it's own and then rest as a tripod on the mouse's palm with some arms to 'clamp' onto the sides would work better, it'd certainly put your arm in a more horizontal position which is good

@sullen zinc this is an inherent design issue copied from previous versions... well known. Both of my Rep2's have been running for thousands of hours... before it happened to one. There are several ways to fix this that are reasonably easy, including just replace the cable.

sullen zinc
#

@coarse ruin indeed, I have a new motor cable on order and am looking at printable drag chain designs. Thanks for the reassurance that I'm not alone

violet needleBOT
coarse ruin
#

@sullen zinc the nature of the failure is related to using cable and connector that isn't design for / rated for lots of flex. Cable management solves another issue which is pinching / min bend radius. The solution I used was to splice in a section of cable like this https://www.adafruit.com/product/3891

#

of course if you can source the cable complete... that would be better.

violet needleBOT
sullen zinc
#

@coarse ruin yeah sourcing the right housings, crimp-on connectors, and an effective-enough crimp tool is enough to run the hobbyist's month.

#

It also makes me understand why designs like delta and corexy get so much excitement, what with the reduced or eliminated count of wires that are flexing all the time. (well, motor and home switch wires anyway, unless you figured out how to run your hotend without wires)

#

what the heck, let's just treat it as a consumable instead

coarse ruin
#

have you seen the extreme wire support of the PRUSA i3 MK3...better than most. I would never recommend a human to crimp wires, robots only. the silicone wire splice would have to use the old crimps. p.s. I design electronics for the day job. I'll see if i can take a pic of the one i have done.

sullen zinc
#

so you keep the original connectors and make two sets of splices with the flex-rated wire?

coarse ruin
#

yeah... that is what i did for this one... not suggesting it is best... just what i could get done and would perm fix the issue.

guys anyone had a go with grbl code before? i want to take out current position out with PWM, I dont understand the code structure, if anyone has done anything similar, please let me know.

shy kelp
#

Grbl is for cnc's. 3d printers use GCODE

versed wren
#

CNCs use GCODE

#

it's in fact where GCODE comes from

#

first result for grbl on google [grbl is] an open source, embedded, high performance G Code parser

shy kelp
#

Wow. Didn't know that

#

As of right now l, however, grbl dominates cnc and gcode dominates 3d printers

versed wren
#

grbl is a parser, gcode is a language

#

it's like saying mono is better than C#

shy kelp
#

No idea what a parser is but ok

#

Just stating what I know

#

Or what I think I know

#

You never know

versed wren
#

the parser takes g code and turns it into machine instructions

#

mono takes C# and makes the processor do stuff

shy kelp
#

Seems legit

versed wren
#

tldr, the servos on your 3D printer don't know what to do with G1 X19

coarse ruin
#

there are G codes that are specific to machine, and use... i.e. most CNC's don't have a nozzle heater PID, and most 3D printers don't have a tool changer. grbl can and is used for additive and subtractive systems. There are plenty of common G and M codes used for all machines (e.g. go to x, y, z)

versed wren
#

even on machines with machines that share 100% of their functionality, G code support varries an embarassing amount

#

used to work in a shop with 3 mills and 7 lathes, no two machines supported all of the same codes

coarse ruin
#

yep.... nothing "standard"... just very very similar...

#

and of course if that was not enough there are other machine interfaces that do the same thing... but change the syntax and encoding... like HPGL and RML1

(p.s. i really need a G-code to RML1 converter... can you say roland MDX)

versed wren
#

is there any kind of elastomer filament that could be used to print custom elastomer pads for the trellis grids?

#

I'm thinking elastometer key sheet with rigid plastic on top, probably rubber cemented together

versed wren
#

working on making molds out of the elastomer files, this looks cool

coarse ruin
#

There are a lot of silicone's to pick from when molding. PUR is cheaper but tends to stick to everything.

#

i can see some fine detail in the above image you will want to avoid for either 3D print or casting.

#

most rubbers have a high viscosity... so you likely will need to vac degas them to get a bubble free result.

#

PUR sticks to PLA... so maybe you could print on fabric, ninja flex, and top it off with PLA?

versed wren
#

the fine detail isn't super important

coarse ruin
#

in the image these are folds that make a flexible long travel button...

versed wren
#

the first image is the negative mold of the bottom of the elastomer sheet

coarse ruin
#

yes... those little folds near the main central tower are where bubbles with get trapped.

versed wren
#

that won't impact functionality

#

the ring next to teh tower is there exclusively to hold the carbon rubber ring, if the space it goes in isn't that clean, it'll still work fine

#

tldr, they're not folds

#

TrueCast20 has a working life of 45+ minutes, so it would be reasonable to fill small details with a syringe for optimal results, the plan is for normal results to pour the resin into the bottom mold, shake it a bit, and then press in the top mold, the towers will be coplanar with the back of the top mold once assembled so depth can be set just by clamping flush, and XY wise there's .25mm play at each edge, so basic shims can be used to center

#

looks like standard aluminum soda cans are 0.1mm thick, so 2 layers of shim on each side, probably a pair of shims on either side of each corner, would ensure that the folds come out uniformly

serene laurel
#

@stray spruce Give me your shiny filaments!!!!! Or at least a url of where to buy them!!! I need Shiny cats!!!

stray spruce
#

Some tips with this filament:
-layer adhesion is not great
-you’ll notice it’s a bit more flexible than normal PLA, on the spool. It’s not flexible filament but it just feels less brittle than normal PLA.

#

So print nice solid objects with inner infil

#

Not thin things

#

Also be sure it’s properly secured to the build plate....has a bit of trouble with that too

#

It’s pretty good if you consider the limitations

#

I’ve only had one failed print I think
