trying ABS now but can't get dang thing to stick to bet, going to try this acetone abs method

modern nacelle
#

PETG is definitely really good for snap parts, it is a bit springier than PLA

golden mica
#

Ey,

#

Im taking a class in school called Manufacturing. Its really fun and we are getting into stuff like CNC machining and other methods of prototyping. We have several 3d printers too, and we will be getting into those later. Im really interested in 3d printing because of its ability to take 3d models on a computer and make a physical model of that computer model surprisingly fast, something that would prove very useful for me as I have gotten into 3d modeling using blender and Autodesk CAD. I was hoping someone with a lot more experience in 3d prining could make some suggestions on what printers are cheapest yet still relaiable and at least decent quality

pale python
#

@modern nacelle thanks, i'll order some and try it!

modern nacelle
#

@golden mica how much are you willing to work to keep the machine running?

#

We have some machines that never need service, but start at 30k

#

If you are willing to put in the effort, a good starter would be a Monoprice Mini, or a Makerfarm Pegasus if you want a bit bigger.

The prusa i3 mk2/mk3 are highly reviewed and positively regarded consumer printers that are sub $1000 usd.

boreal lava
#

@viscid kelp I have a two-up that I am in the process of upgrading, but is getting pretty solid prints. I'm happy to help where I can.

#

@golden mica @cloud halo yes. it's really hard to go wrong with the prusa design. There are so many mods and adaptations, that you almost have to fall on something that works for you.

golden mica
#

Hmmm, Ok, ill take a look around and ask some of my neibors and friends that have them, thanks for the advice tho!

cloud halo
#

@boreal lava That's what I love, the large userbase. Just like the old saying "No one ever got fired for going with Microsoft/IBM/EMC...", it's hard to go wrong with choosing a popular development/prototyping platform. So many people use Arduino/RaspberryPi/Prusa/etc that you have security in numbers.

modern nacelle
#

I'm not a huge fan of the Mk2/3 personally.

#

They can be finicky at times, and many parts are hard to come by spares.

#

The MMU is fantastic though

uncut ledge
#

mk2 outclasses practically every machine sub 1500

#

mk3 is.. personally a bit more than i want from a printer to the point of it being a burden

#

and PETG is my go-to plastic these days for anything that isn't a show piece

#

there's no reason to not use it over ABS unless you want to acetone smooth or it needs to survive above 75c

covert ferry
#

I ❤ my Mk2. Haven't done the S upgrade nor the multi-color (yet?) Was finnicky until I got the Y-axis perfectly aligned. Hasn't had an issue since February. I love my Proto-Pasta, their matte filaments are amazing

#

I looked at the Prusa but it looked like the frame wouldn't be as rigid as a box frame design.

boreal lava
#

@karmic brook The box ones do seem stronger, which is why I am going for that design on my next build. Honestly though, the standing frame design is plenty rigid. It just becomes an issue at higher speeds if it is not reinforced well. As long as you go at a moderate pace, they are great.

devout sable
#

I run my mk2s at 120mm/s and it’s perfectly fine, no issues with ringing or the frame flexing. The mk42 head bed is incredibly light so there’s way less stress on the frame than some of the heavier glass beds. The only issue with the frame is the initial setup and getting everything square but that’s just a bit of patience and measuring stuff a few extra times to double check

#

@uncut ledge look where i found you...

#

currently my printer is broken, its just turning off midprint, and going to its loading screen.

modern nacelle
#

sounds like you're drawing too hard on the power supply. happened on one of my printers

weary lichen
#

This printer is currently $154 on Amazon

#

Has anyone dealt with it?

modern nacelle
#

@harsh laurel I own 3 of them, really good starter printer

sacred oyster
#

@modern nacelle

#

other people have had the same problem on the same printer

#

hwo would i fix it?

modern nacelle
#

Hm. What printer is it?

sacred oyster
#

The Microcenter rebrand of the duplicator i3 plus

#

the Powerspec Duplicator i3 Plus

#

@modern nacelle

modern nacelle
#

Hm, I'll do some digging and see if I can find a fix. I'm guessing you're in the US, so 110v power input?

sacred oyster
#

Pretty sure, idk 😛

#

@modern nacelle

#

It started right as i was gonna start building a nice robot arm

#

Rip

modern nacelle
#

Hm, what material were you printing at the time?

sacred oyster
#

Pla.

modern nacelle
#

Alright. My best guess is that the power supply can't provide the power needed, which is unlikely. Could also be a firmware bug. Try running the print again, keep an eye on the temperatures. That'll tell you the issue.

sacred oyster
#

Printers not here 😛

#

It printed one thing fine

#

I mean the quality was crap

bright olive
#

Venting: I'm doing a model and it's incredibly detailed considering my lack of inexperience, and fixing all the geometry whoopsie-daisies in Sketchup is nine kinds of a chore.

#

That instantly went better by exporting a different format and letting Shapeways handle the conversion and slicing.

weary lichen
#

I did end up buying that 3D printer. And some filament. It will fuel all sorts of shenanigans, I am sure.

uncut ledge
#

You should probably steer away from sketchup as well

weary lichen
#

I've personally used FreeCad in the past

#

Noted, thanks

@modern nacelle

modern nacelle
#

Yo

#

How'd the print turn out this time

boreal lava
#

For designing mechanical/functional items, Fusion 360 is hard to beat. It is a bit more fidgety when it comes to organic shapes, but is still workable.

#

@modern nacelle

#

i still havent got it working, i opened up the back and nothing look burnt, hm

Not sure if velocity painting is a new technique for this crowd, but I haven't seen it before.

Here's an example with Repetier Host, video in spanish but should be pretty clear even in mute 😃

#

Sweet. My printer arrived a day early

#

Buuuut I don't have much in the way of filament until tomorrow

boreal lava
#

@weary lichen I have nothing but good things to say about Hatchbox filament. I've never bought $30 a kilo spools, so maybe my view is biased, but at around $20 a kilo I have had good results.

weary lichen
#

The filament that's arriving tomorrow is Hatchbox

boreal lava
#

Awesome

weary lichen
#

And now, for a super small tiny test print with the included "sample" filament

#

It moves! This is all so exciting.

willow sedge
#

@weary lichen Nice!

weary lichen
#

It's tiny and, uh... stuck.

#

Scraper is not working. Seems to be super thick plastic so not surprised. Best idea?

#

Got it! Pair of pointy tweezers

#

I love that I can just drop things on a SD card and not have to worry about location.

#

Hmm, that'll have to be addressed. Started printing but only came out with a glob at first. Nozzle seemed too high?

#

I'll have to fiddle with it tomorrow. I'll finish this print but then it's sleep time.

tribal egret
#

@weary lichen did you level your bed?

boreal lava
#

@weary lichen There's a lot that goes into setting up a new printer. Don't get discouraged.

weary lichen
#

@tribal egret I leveled the bed firsr thing but that's also the first thing that came to mind. Print quality otherwise seems grand though

#

And @boreal lava given the great super simple prints I have had so far, I am anything but discouraged.

tribal egret
#

that's great @weary lichen 😄

weary lichen
#

Indeed! I'm excited to get home and start fiddlig with it

unkempt remnant
#

Hey, group mind--any suggestions for 3D printers <$200?

#

Looking for a starter to see if it's something I'd want to invest more into.

bright olive
#

The Monoprice Select Mini at $230. Maybe you can find an open box for less if you want. But I wouldn't go lower

unkempt remnant
#

Yeah, it was a relatively arbitrary pricepoint

weary lichen
#

@unkempt remnant I just got the V2 mini on Cyber Monday for 165ish

#

Seems solid and well built

unkempt remnant
#

Looks like they've got a promo code all week

weary lichen
#

Mine was from Amazon, so it arrived next day. Which was awesome

unkempt remnant
#

Lemme know how you like it!

#

Well, it looks like (so far), the web uploading is working.

#

Waiting for it to heat up before I will hit print, though.

#

Well, it's been printing for a bit now

#

I love the sounds it makes

supple helm
#

hehe, totally

#

oh yeah those monoprice minis on amazon were a great deal

weary lichen
tribal egret
#

@weary lichen are you aware of the heated bed fix you might (should) do eventually?

#

@weary lichen thankfully its an easy fix, and you can skip drilling a hole through the body by printing a side plate or other workarounds on thingiverse

weary lichen
#

@tribal egret I had not seen that

#

Printer in the vid isn't exactly the one I have. At the very least the plate attachment is different.

tribal egret
#

@weary lichen doesn’t matter if it’s v1 or v2, — the video shows a v1 before the v2 came in white. v2 has the design slightly adjusted but the mod will still need to happen eventually.

weary lichen
#

I'll have to look in to what's the easiest method for doing so. Definitely don't want my printer breaking from an "easy" fix

halcyon hedge
#

How much of an issue are fumes assuming you stay away from ABS?

weary lichen
#

Doesn't seem to be an issue to me so far.

weary lichen
#

Ack! Is sph
Ack!

#

Is spaghetti from a too high extruder temp?

tribal egret
#

@weary lichen I have the same V2 printer, had it for ~ oh less than a month, then the heated bed stopped heating up. If anything just be mindful of the bed temperature, if its not "Heating up" then you need to consider looking at the wiring. Mine frayed (check the facebook group for the printer for similar threads) -- learned how to properly splice wires because of it xD

weary lichen
#

Spaghetti was from filament being a little too far forward.

#

Also, I'll take a look at the wiring

tribal egret
#

@weary lichen just lookin' out fer yah !

weary lichen
#

Sensible!

weary lichen
#

So, the "Underside" of my prints (With support) are looking like hot garbage. Is this normal?

tribal egret
#

@weary lichen hot garbage? Like?

weary lichen
#

So, I printed a gear out. The top looks nice and smooth. The bottom has lots of lines going everywhere, they're not regular, and it's very rough.

tribal egret
#

@weary lichen my workflow for good first layer is rubbing the bed with isopropyl alcohol then preheating the bed and hot end to 200 (PLA) and 60 on the bed. After it’s “warmed up” the first layers tend to adhere better

#

@weary lichen ah, may need to get a glass pane to make it smooth

weary lichen
#

No, not for touching build plate

#

That ends nice and smooth

#

It's stuff above supports

#

One on right HAD a peg, but it was too small and broke off. The back of the one on the left looks just like that, too

tribal egret
#

Using which slicer?

#

Use a different support pattern

#

What’s your temperature settings?

weary lichen
#

Support is "Everywhere"

#

190/60

#

I had previously been using 210/60 with the included filament but the recommendation for the Hatchbox stuff was 190

tribal egret
#

Everywhere in the setting but the pattern

weary lichen
#

I didn't see a pattern setting in the program.

tribal egret
#

Would say something like “zig zag” etc

weary lichen
#

Cura is what I'm using.

#

aha, there it is

tribal egret
#

Which version?

weary lichen
#

15.04.6

#

The newest version yelled at me and wouldn't start, so I installed the one that came with the printer

#

I just wanted to get the printer working first.

#

Strucutre Type is "Lines" with overhang angle of 60, 15% fill amount, 0.7mm X/Y distance, and 0.15 Z distance

weary lichen
#

It only has "Lines" and "Grid" available

tribal egret
#

Latest one should work. The quirk there is you have to select the printer on the menu before you can slice it

weary lichen
#

Oh, it was an OpenGL issue.

#

Said something about not being able to find something and just wouldn't start at all

tribal egret
#

Hm! Not familiar with that

weary lichen
#

I did a google search and found absolutely nothing, so I gave up and tried the older version.

tribal egret
#

Yeah, can’t help with that atm sorry

weary lichen
#

No worries.

#

I'm more worried about things looking awful.

tribal egret
#

Also how fast are you printing?

weary lichen
#

30mm/s

tribal egret
#

Hmmmmm

weary lichen
#

Infill at 50mm/s

tribal egret
#

Should be aight. Only thing I can’t think of is the pattern

#

Maybe lower the travel speed to like 30mm

#

The z axis only has one arm support

weary lichen
#

The gears I printed with the included filament look fine. I'm going to print one of those with the same settings as the old filament.

weary lichen
#

I know I have printed with higher layer height, which is the first thing on the list.

tribal egret
#

Yeah leveling the bed 🛏 is a crucial step

tribal egret
weary lichen
#

I ran into that earlier today.

#

Super useful info

weary lichen
#

@tribal egret New prints look next to identical to the older ones. Definitely going to call it a layer height issue

#

Huh. Neat.

#

Not going to need that anytime soon, but still neat

vast salmon
tribal egret
#

@weary lichen :3 definitely something to consider if you wanna try filaments with additives 😄

weary lichen
#

Yeah, which isn't something I'm going to be doing soon.

still panther
#

@vast salmon , very cool. Next step, let it turn itself based on who is talking.

vast salmon
#

it's cool that it even use adafruit tutorial diagram

weary lichen
#

Had my first print failure today. The bed was never set to heat (oops), and somewhere after the first few layers the whole thing got knocked off the build plate. Cue a bunch of spaghetti.

#

On the plus side, what did print was plenty enough to check my measurements and verify that mount hole placement and the like was correct, so that was great.

#

The re-print of the part is almost done, according to the web interface. I should probably go check it.

slim escarp
#

Much like @weary lichen I also jumped on a monoprice 3d printer sale last weekend, only I got the mini delta. Had some issues with the auto bed leveling where it would aim off the build plate, but removing that line in the gcode & doing a manual homing before starting a print seemed to fix the issue but I have a question about it in the facebook group for the printer

weary lichen
#

Nice! I was wary of the Delta printers. They look cool but as far as mechanical complexity goes, there's a significantly large amount of things to break.

slim escarp
#

@weary lichen yeah it was definitely a calculated risk but I liked the form factor & the review from Hackaday was very positive

weary lichen
#

The Mini V2 has an issue which I plan on addressing, in that the wires for heating the bed are poorly placed and will eventually kink and fray.

slim escarp
#

That's one thing that I think is so cool about 3d printing, that you can upgrade or fix basically any issue yourself so then you don't have to go crazy for an expensive machine if you don't want to

#

hey all, I'm thinking of making a Zelda chest as a secret santa preset (complete with chest opening jingle and lights inside)

#

I'm thinking of making using popsicle sticks and a 3 print

#

So print a a sorround and stick popsicle sticks to the inside

#

So I would cut and stick popsicle sticks to the inside to hopefully give a nice effect

#

Does anyone have good recomendations for the hinge part?

opal shale
#

Print failed, but it was only a tester anyways, I think it looks pretty good

weary lichen
#

@opal shale For the hinge, you can usually go to craft and/or hardware stores (And/or walmart maybe?) and get tiny hinges.

tribal egret
#

@opal shale maybe something like this? https://www.thingiverse.com/thing:82533

I searched the Thingiverse for a simple hinged box that was parametric and printed all in one piece. I couldn't find one. I did find some really neat parametric boxes and lids though. I used none of their OpenSCAD code for this.
I've printed probably a dozen one piece boxes with hinge during my testing. I wanted a tight hinge that would reliably print and NOT fuse together. During my testing I experimented with different speeds, temps, and tolerance values in my SCAD files. The attached OpenSCAD files prints reliably on my printer. The resulting hinge is a bit loose but it reliably does not fuse. Changing the tolerance by .1 does make a much tighter hinge, but sometimes I could not break it free. YMMV.

#

just the hinge part - maybe you could build it into the frame?

opal shale
#

Yeah that seems good!

#

Thanks @tribal egret

#

I use thinker cad 😋

#

Terrible quality, but I was playing around with the circuitry for this

#

I need to get a normally closed reed switch though

weary lichen
opal shale
#

I dont know @weary lichen but i am curious!

#

I have the same slip ring adapter that i got for a project and curious to see what you do with it

#

would you mind linking to the STL?

weary lichen
#

Sure, I can put it up

#

It's the gear for a turret ring for an RC tankbot I'm working on

#

Agh. Time to type all of that up again

#

AGH

#

Thingiverse is NOT liking me

#

A gear designed to work with this slip ring.
It's a 1mm pitch, 54-tooth gear. The grommets and washers allow for use of M3 screws without nuts.
The holes don't line up perfectly, but you can convince the grommets to go through with only a little effort.
I didn't think about the difficulty of holding the grommets still while inserting the screw, so they'll have to be gripped with a pair of pliers or something similar.

#

@opal shale It's up on Thingiverse, despite the website trying to fight me the whole way

serene basin
#

Does anyone know where I can find a sled to hold my Adafruit Metro that I can 3d print?

tribal egret
#

@serene basin isn't that the same formfactor as an UNO?

serene basin
#

Yeah I think it is the same shape

tribal egret
#

that's great @serene basin 😃

shy kelp
#

Just measure it first.

weary lichen
#

Finally got the stepper motor lined up

shy kelp
#

How much do the wires twist, if at all?

weary lichen
#

It's a slip ring.

#

They don't.

#

The top part (Connected to the gear) can spin to its heart's desire.

#

Except it doesn't have a heart.

opal shale
#

Do you have a link @weary lichen that looks exactly what I was after for my project!

weary lichen
#

@opal shale Thingiverse link for the gear is above

#

I'm still working on "perfecting" the mount.

opal shale
#

oh sorry!

weary lichen
#

No worries!

opal shale
#

i scrolled up til i saw the pictures and i thought they were the ones you posted earlier!

weary lichen
#

Heh, it happens.

opal shale
#

My idea was a clock

weary lichen
#

What project are you working on?

opal shale
#

I was going to use UV leds and glow in the dark paint

weary lichen
#

Oh, neat!

#

I'm building a LoRa TankBot.

#

now that I have the 3D printer, I'm actually able to build the tank from the ground up instead of modifying something that already exists. Gives a bit more possibility.

#

I totally intend on putting the largest laser I can afford as the main gun. It probably won't be much, but it might be able to pop baloons or light matches.

opal shale
#

If you skip about two minutes into this video it shows the effect i was looking for

weary lichen
#

Oh, that is COOL

opal shale
#

The UV light leaves behind a "mark" on the glow in the dark paint

#

So I was thinking, one single hand continously rotating

#

would light up the appropriate places for the minute and the hour hand

weary lichen
#

I wonder if that Glow-in-the-dark paint would glow if painted on a translucent/transparent surface and illuminated from behind

opal shale
#

Thats interesting, I was going to face the LEDS back towards the surface

weary lichen
#

It might not work at all, but might be worth a try

weary lichen
#

It lives!

opal shale
#

Did a bit more work on the chest, will try print out the lid tomorrow

weary lichen
#

Man. It's amazing how much difference half a millimeter makes when it comes to gear meshing

opal shale
#

Probably need to reprint on its side as the support is tough to take off

#

But pretty happy with it

weary lichen
#

That is cool

#

Thanks @tribal egret !

#

I think I'll print the hinges tonight and see does that work out

weary lichen
#

Have to say, designing parts that need things in both millimeters and in inches... is very annoying.

#

Especially because FreeCAD does NOT like inches

weary lichen
#

5 iterations to get a mount for a feather right where I want it. Not terrible, but if FreeCAD had worked better in inches it wouldn't have taken that many

karmic tapir
#

🎉 at least it didn't eat up to much plastic. How come you didnt want to try fusion?

weary lichen
#

BEcause FreeCAD works very well for the stuff I'm doing and is, well, free.

#

Also, almost everything I work in is metric, so FreeCAD is fine. IT's just converting the measurements that's annoying.

#

And yes, Fusion360 is "Free" for hobbyist use. I do have a company and would like to be able to sell the stuff I work on.

karmic tapir
#

Gotcha, makes sense!

weary lichen
#

So far, I'm absolutely loving FreeCad's "build-a-gear"

#

I designed and printed a gear that's a replacement for a metal one I had bought. First print, works perfectly.

honest haven
#

First print, works perfectly? Impossible.

weary lichen
#

I took many measurements!

honest haven
#

Ah, you are that Measure 50 times, print once kind of guy

weary lichen
#

When it can be measured easily

#

And/or if it requires longer prints

honest haven
#

True, for longer prints you want to measure a lot.

weary lichen
#

This was "only" about half an hour, but it's also right before bed.

honest haven
#

For my first acrylic box I got it right but a little too right

weary lichen
#

Haha, I've done that

honest haven
#

It slid apart just as easily (actually hard) as it was put together

#

No friction, and it was laser cut.

weary lichen
#

Mmm lasers.

honest haven
#

Also, my college is really cool. It got a Aluminum Laser Sintering printer

weary lichen
#

Ooooh shiny

honest haven
#

I'm waiting for it to get setup so I can get someone to print me something on it

#

I know the guys in that shop

weary lichen
#

Always a plus.

#

Well, the gear worked, and the nighttime cold meds are starting to kick in. Going to sleep some.

#

I'll take/post pictures and post up files on Thingiverse tomorrow

@supple stratus @idle crest for dock video think Microbit and aka.ms/devkit dock with edgeconnector bottom base

weary lichen
#

A gear designed to work with this slip ring, along with a mount and gear to use with a 28BYJ-48 Stepper Motor such as this one
The slipring gear is a 1mm pitch, 54-tooth gear. The grommets and washers allow for use of M3 screws without nuts. The gear for the stepper motor is a 1mm pitch, 15-tooth gear. Depending on print accuracy, you may require a M3 screw to keep it in place. Mine fit snugly over the stepper motor's output shaft with a small amount of force. The bracket also takes two M3 screws to mount to the stepper motor.
The holes for the slip ring don't line up perfectly, but you can convince the grommets to go through with only a little effort.
I didn't think about the difficulty of holding the grommets still while inserting the screw, so they'll have to be gripped with a pair of pliers or something similar until I update them.

#

@supple stratus from the USB dock i was thinking if you have USB-C booster and then modular dock to it like Usb breakout so it charge your device depend device charging like lightning connection or Qi charger or miniusb or usbc

#

one time i got this multicharger puck what have multiple charging modules so why not hack it and modernize it

shy kelp
#

@supple stratus @Pedro The slider needs to withstand outdoor use, is it possible or too late to review/comment/augment the design before publishing?

supple stratus
#

@shy kelp sure i'm open to the discussion. I've been testing it quite a bit inside and once outdoors (i posted a test shot on instagram). The latest CAD model is public here ehttp://a360.co/2AMIomg

shy kelp
#

@supple stratus Whoah, very nice! My main concern is dirt and water/snow, but at first glance, I don't see much problems. My hobby is nature timelapses, so yes, I take pictures when it rains 😉 What are you planning on using for the electronics and power? Edited: OK, I found out -> Metro 328

supple stratus
#

@shy kelp Ah thats very cool hobby! Most of the electronics are housed in the case but some things are exposed like the belt, pulley and bearing. Not sure what type of metal the support rail is made out of but the aluminum extrusions (hopefully) don't rust. To power the boards + stepper motor i just have it plugged into the wall with a 12v adapter but could also use a 8x AAA battery pack.

opal shale
#

Got some hinges for my Zelda chest, these are just temporarily double sided sticky taped on but the seem to be working well

#

2mm hole in the hinges and I'm using some filament as the bar

#

I melted one end with my soldering iron to keep it in place, once its in its final resting spot I'll melt the other side

shy kelp
#

@supple stratus No one needs legs on the bar mounts? Having 2 2-inches stubs on each end would allow us to put the slider on a surface and be stable rather than resting it on the tripod pad?

opal shale
#

Bottom part of the chest printed out so I now hopefully have everything printed

#

It's going to be a tight enough squeeze though so hopefully its big enough!

@opal shale That looks great

#

Thanks @weary lichen , I'm thinking of staining/varnishing the wood to make it darker

weary lichen
#

That will look grand

rough marlin
#

@opal shale What did you use to hold the popsicle sticks together? In the back of the box I see a thick grey line, Is that clay or something like that? Or did you just use super glue.

opal shale
#

Hey @rough marlin my plan is to use super glue, but what you see there is called blu-tack , that's just a temporary thing to see what it looks like

rough marlin
#

oh, cool

opal shale
#

Its kinda moldable putty or something

#

You might use it for hanging posters on walls

rough marlin
#

yeah, it kind of looks like clay

opal shale
#

Its really good for soldering too

#

You can hold things in place

rough marlin
#

oh ok

#

btw i like what you made its really cool

opal shale
#

Thanks!

wow that looks great 👍 👌

#

@opal shale you see the side on this chest, there isn't a metal part. On yours the side is all 3d printed, maybe you could make the frame 3d printed and everything else wood

weary lichen
#

@rough marlin Brian's grey frame is 3D printed. Then he put popsicle sticks in for the wood

rough marlin
#

i think it would look better if it were just wood

vast salmon

looks like @glossy light mystery Chest

weary lichen
#

Ah, I see what you mean. But the chest is very small so I'm not sure how structurally sound that would be

opal shale
#

That was my original plan @rough marlin , I might try another print where I take out a piece in the center, I'd probably only fit one stick in there though

#

I might not have time though 😂

rough marlin
#

its okay, yours looks great

#

did the video game and the electronics fit in?

opal shale
#

I have to solder up the electronics yet, I think they will

#

I can change to a coin cell battery instead of the Nintendo D's battery if I need to save space too

#

okay

#

Attinys are crazy flexible with what voltages they accept!

thats perfect for the box then

@supple stratus @idle crest how you guys would 3D Print mailbox? as I was thinking to include the MXChip IoT Devkit what i put #show-and-tell as it have magnetometer so when the mail is delivered it notify house

hmm, maybe with the back end of it on the bed and then have nubs on the sides for the door hinge?

@vast salmon depends on the shape but maybe best to print in pieces. could do all-in-one tho

oh thats a neat kit. would be easier to stuff the board into a waterproof project case and mount it to the mailbox

@supple stratus it comes with adafruit driver

Hi, NOOB to 3D printing, so this may be obvious to someone else, but not to me... or it may be a design flaw (ouch).

#

I downloaded the 3D printable cases for circuit playground. Then I built the round one with PLA filament. I was easily able to affix the circuit board to the new case with number 4 sheet metal screws. Next I built the HEX case, also from PLA (different color). When I went to install the circuit board, a problem arose. The holes in the case were too large of diameter for the M3 screws specified, and they are also too large for the #4 sheet metal screws. Any larger screw will not clear the holes in the circuit board. . . Now my question - Has any one else had this issue? Could it be slight diferenced in the two different PLA filiments (other than one's gray, the other is orange)? The only other soltion I can come up is fill the hole with epoxy, let it dry, and then drill to a more reasonable diameter. Comments, please.
😩

weary lichen
#

@trim sail There's going to be some minor inaccuracies for 3D printing, so screw holes may not be perfect. Do you have a link to the case?

uncut ledge

that's pretty weird, most printed parts tend to be slightly too small

Ooh, that looks nice.

@trim sail It was @supple stratus and @idle crest who designed that case. They may have made the holes a little larger than normal, so you may need to asjust things.

And the CP case saga continues... Today I printed the third case (of the three). It works magnificently. So now, for those of you keeping score: Square & Round are tied with 1 each (they both worked) and Hexagonal has 0 (as in FUBAR).

#

@trim sail I also got myself a MonoPrice Select Mini V2! In the Black Friday sale.

#

So far it's been painless for me, but I haven't tried printing any enclosures yet

#

I say typing on my laptop right next to the printer that's trying to run off one of the Micro USB cases from this week's 3D hangouts.

#

Not cases, docs.

#

docks.

#

Sorry, too much blood in my caffeine system.

#

And, my first print nozzle jam, I think.

#

help, how does one clear a jammed up nozzle?

#

Or am I just going to have to wrench out the nozzle and replace it?

weary lichen
#

@silent veldt Are you sure it's jammed? Have you tried heating the nozzle and pushing filament through by hand?

#

I haven't had a jam/clog on mine yet.

#

So my recommendation is to look it up via google. There's also a Facebook group for mini V2 owners that has been super helpful

trim sail
#

@pcurryinahurry @weary lichen No nozzle issues here. Just make sure you preheat it then run some filament through it (I usually use the Move-Extrude menu).

#

OBTW, I have not had any luck with USB printing. Are there some magical incantations I need to know. My setup is PC - USB hub - 3D Printer. out of a dozen or more prints I have been able to get USB printing to work only once.

weary lichen
#

I use WiFi

#

Haven't tried USB. No room.

silent veldt
#

I haven't tried USB. I haven't cracked the case open to enable WiFi.

#

I think I have a nozzle jam, because it stopped passing filiment in the middle of a print run. I thought I had preheated it enough, but apparently it cooled too much.

#

Won't extrude at 220C with manual control on the extruder motor. I couldn't get it to move forward by hand.

#

Then I left for 4 hours.

#

So I can reheat the block and see if that makes a difference.

I'm using the low poly Pokémon models by Flowalistik to fine tune my printer & also get a little bit more used to 3d printing in general. Also I just love Pokémon haha. But I wanted to share some mistakes I made because I think that's important for learning. The left Bulbasaur is crooked as a result of improper leveling. The middle is a result of not wiping down the print bed & having temps a little too low. The right is a successful print 🙌

Has this already been mentioned here? https://www.thingiverse.com/thing:2676324

The Measuring Cube | Original:

1 cup, 1/2 cup, 1/3 cup, 1/4 cup, 1/5 cup, 1/4 teaspoon, 1/2 teaspoon, 1 teaspoon, and 1 tablespoon containers. Size: 90 mm (3.5") cube.

The Measuring Cube | Version 2:

1 cup, 1/2 cup, 1/3 cup, 1/4 cup, 1/8 cup, 1/4 teaspoon, 1/2 teaspoon, 1 teaspoon, 1 tablespoon and 1/2 tablespoon containers. Size: 89 mm (3.5") cube.

The Measuring Cube | Metric:

250 mL, 125 mL, 100 mL, 75 mL, 50 mL, 1/4 teaspoon, 1/2 teaspoon, 1 teaspoon, and 1 tablespoon containers. Size: 93 mm cube.

All containers share (within reason) common walls for the most compact shape and the minimum filament use.

How to use: fill all the way up for the correct volume for each container.

We printed at 0.1 mm layer, 12% fill, 0.2 mm layer should also be fine. Supports: NONE.

Please see our popular binary titanium key carabiners made from pure titanium, with the safety cage to keep your keys secure, and the built-in bottle opener.

Printing one out right now. It's only 90mm, so it should print on just about any printer.

So, after re-heating and manually pushing filament, extruder is working again! Printed the lid of the project.

@silent veldt WIFI on the MonoPrice Select Mini V2 is easy. Follow the directions on pg 11 of the manual . It requires you to install an IOS or Android app on your phone/tablet. But after that its a snap. What the manual doesen't tell you is how to send files. With a uSD card installed that has room for the gcode file, point your PC or Mac's browser to the IP address shown on the printer's display (10.10.10.106 in my network). No need for http... or port numbers, etc. A web page should pop up that's so easy to use (albeit slooow). Drag and drop your gcode file, set your temps, then click print. Should work!

weary lichen
#

@trim sail has it right. It's super easy to set up with the android app.

#

Printing is weird. Sometimes you'll upload and it'll auto start. Sometimes it won't.

#

Also, if you set the temps to preheat it, then upload, the preheat is turned off at the conclusion of the upload.

#

As with normal prints, gcode will set the temps for the print just fine, but you can override it

vagrant ridge
#

I really recommend just setting up Octoprint rather than using the built-in wifi on the MPSM. Heck, the newer versions of Cura even allow you to skip the drag and drop phase of uploading gcode.

weary lichen
#

I'll be upgrading to OctoPrint eventually, since it lets me have cameras and such

#

But the onboard WiFi is perfectly functional and works great

Hmm. I want to talk design of a 3D printer. Anyone have any Facebook groups/forums/etc dedicated to that sort of thing?

Achievement Unlocked: After a year of 3D printing, I just had my first print failure due to loss of bed adhesion.

I've had to stop prints from time to time due to a curled corner or a failed first layer. I've also had them fail halfway through due to bad supports. But never had the model actually tip off the platform till today.

#

You can't say I'm heartless

shy kelp
#

Thinking of buying a monoprice select v1. Good idea?

weary lichen
#

@shy kelp I'd recommend the V2

#

The mini V2, at least, over the Mini V1

#

Be aware, though, that both versions have an issue with the wiring for the heated bed - Two, actually. One is a location on the wires where they bend a lot more than they should, which can cause them to break. And two is a location where the wires can rub up against the bed's belt, which can cause the wiring and/or belt to go bad.

#

It's a fairly easy fix, although I have yet to do it

shy kelp
#

Can't afford a v2

#

Yes the one I found bed does t heat

#

Doesnt

#

But seems like an easy fix

weary lichen
#

Oh, getting it used?

shy kelp
#

Yep, can't afford it new

weary lichen
#

Replacing wires should be fairly easy (Especially if you're in this Discord server), and you can easily run the wires in a better location while you're at it.

shy kelp
#

Nice

#

Doesn't a no heated bed affect prints that much?

weary lichen
#

With PLA? Not really.

#

The larger concern is the belt for the bed. I'd at least make sure the wires aren't chafing on that.

shy kelp
#

Any big errors with the v1?

weary lichen
#

None that I know of

shy kelp
#

Last question

weary lichen
#

I only got my V2 a month or so ago, so I'm fairly new to it

shy kelp
#

Is a computer connection required or can it rely on sd

weary lichen
#

If I remember correctly, the V1 doesn't have Wifi, but both the V1 and V2 can print directly from a SD card

shy kelp
#

You just move the stl to the card?

weary lichen
#

You have to run the stl through a slicer (Such as Cura or Slic3r) first to generate the gcode file

#

But then you put the gcode on the sd card and put the sd card in the machine

shy kelp
#

Alright, I use slic3r with my laser so I'm good with that

#

Alright

#

Is it mostly plug and play?

#

Or does it require tons of setup?

#

It comes calibrated

weary lichen
#

You'll want to level the bed

shy kelp
#

Is that hard to do?

weary lichen
#

nope

shy kelp
#

Is there a way to accidently ruin a 3d printer?

weary lichen
#

Many, but none that I'd be worried about.

shy kelp
#

Thanks for the information

#

Gonna purchase now, comes with 2 spools of plastic

#

Always useful.

#

They're a HUGE trove of information

#

Awesome

#

I already joined the subreddit

#

Thanks for the help, going to purchase now.

weary lichen
#

There's a few of us on here that have the V2. so we should be able to answer most questions you have about the printer

shy kelp
#

I see the most complained thing about is speed

#

Everyone says it price ts slower than others

#

I don't care for speed so won't be a problem

#

Think you can help me fix the bed heating issue when it gets here?

weary lichen
#

Sure!

#

I intend on doing that soon to mine as well

shy kelp
#

I still wonder how the company missed the issue where the zip tie causes the cables to be damaged

weary lichen
#

the Monoprice printer is a rebrand of... Malayan?

#

Which in itself is a cheap-ish Chinese manufacturer.

uncut ledge
#

no, both are rebrands of wanhao

#

which by itself isn't the worst machinr you can be stuck with

#

$100 in mods and it's a very good machine

weary lichen
#

They seem to be a pretty solid design, minus the bed issue

shy kelp
#

So I was wondering

uncut ledge
#

that's factored into the $100 😂

#

there's a $25 plate on amazon that's much thicker and about 100g lighter

shy kelp
#

Someone mentioned something about how the spool was perpendicular to the head and how it's better to have it lined up so there's less tension on the plastic and motor

#

Is that something to worry about?

weary lichen
#

@shy kelp I haven't had any issues with it so far.

#

Would it be better to have it rotated? Sure. Seems to work just fine as is though

shy kelp
#

Ok

#

What would count as "extended use" for a 3D printer? Since I've seen things that take like 26 hours to print

uncut ledge
#

add a mosfet for the bed and it should be fine indefnitely

#

well, usually you run out of filament first

shy kelp
#

Alright

shy kelp
#

@weary lichen whats the best slicing software for this printer? Can I use slic3r?

weary lichen
#

@shy kelp I started using slic3r yesterday. I can give you my settings when I get home

shy kelp
#

Thanks

#

I've got most things set up

#

The biggest drawback with this printer is the direct upload from computer is broken

weary lichen
#

Well. Maybe "The other day" is more accurate. It's all running together

trim sail
#

About the comment on printing from an sd card... I generally use the WIFI on my V2... with occasional transfer failures. Its convenient, but SLOW!!!. Sneakernetting a uSD card is actually faster, but far less convenient. The web interface is clunky (or is that Klunky?), but it works.

shy kelp
#

The v1 appears to have wifi. Am I right?

#

All the video I've seen the LCD at the top says "No connection" and has wifi bars next to it

#

At least I hope so, I'm not a fan of having to move files onto an micro SD card adapter then to the printer then back each time

#

@weary lichen

weary lichen
#

Let me see

#

Yep, looks like it

shy kelp
#

So you upload the gcode Trough that?

weary lichen
#

Yes. And @trim sail is VERY right about the slowness of it.

#

And it occasionally likes to be stubborn and I'll have to go over and turn it off and back on.

shy kelp
#

How slow we talking? Like super unreliable?

#

Wonder if the wifi chip can be replaced with a Esp8266

weary lichen
#

Oh, no. Just... far longer than it really should take for a file transfer.

#

Unlikely.

#

However.

#

People HAVE replaced the entire driver board

shy kelp
#

Is it like an app or program to upload gcode or an online interface?

#

Yeah not looking forward to replacing a whole board just for uploading speeds lol

weary lichen
#

Web page. You type in its IP address and it brings you to a super simple page.

weary lichen
#

A lot of people use Octoprint for the wireless + other bonuses, but I've heard octoprint can have issues connecting to the printer's USB port sometimes.

#

That is the app that you use to set up the wifi

#

That's all it does, though.

shy kelp
#

Wow

#

I was thinking about using my Pi for octoprint

#

For now I just want it to print lol

#

Wireless upload is going my main mode

weary lichen
#

Yeah, my printer's upstairs. Not far - It's at the top of the stairs and my room's at the bottom, but it's still annoying to have to drag the SD card back and forth.

#

Also, the SD card slot is set in a little bit too far and is annoying to take in and out.

shy kelp
#

I'm really bad when it comes to inserting micro SD cards

#

I broke 3 in half trying to get it in the Pi with a case lol

weary lichen
#

Wow. I've never once broken one.

#

I HAVE launched them across the room, never to be seen again, though

shy kelp
#

Lol

#

I was looking a videos and almost everyone mentioned how bad the thermometers were

#

How the temperature reading fluctuates from 1 sec to another

#

Is that a hard thing to fix?

weary lichen
#

Not sure.

shy kelp
#

So I would go to the little web interface, upload the file and hit print?

weary lichen
#

Yep

#

You can also use the web interface to pre-heat it

shy kelp
#

So since the bed on the one I'm getting won't heat until I fix it, should I set the bed temperature to 0 in slic3r?

weary lichen
#

Yeah

shy kelp
#

Oh, last question

#

I was reading that it's better to have this printer in a room without direct sunlight and lots of drafts

#

Something about plastic warping

#

Should I follow that advice?

weary lichen
#

UV and humidity degrade the filament

#

So try to follow it as best you can.

shy kelp
#

Oh speaking of filament, does PLA smell a lot when being melted? If so does it smell bad?

weary lichen
#

No, it doesn't smell a lot

shy kelp
#

Thanks for all the help Andon

weary lichen
#

To me, it barely smells at all

#

Not a problem

shy kelp
#

Lol I hope all it needs is bed leveling when it gets here

#

The smell of melted pla is great

#

Sweet smell

#

It’s corn based that’s why

#

Adafruit also carries coffee-scented filament.

#

Don't the filaments that are infused with other things damage the nozzle?

#

For brass nozzles, yes

Adamantium nozzles are wolverine-strong.

uncut ledge
#

i would be more in favor of nickel plated nozzles instead of A2 unless you print metal filament or glow in the dark

south elbow
#

Quick question: Is this bad?

#

Theres weird powder (i assume from the filament) on the side wall there and filament shards next to the tube

shy kelp
#

What filament you using?

south elbow
#

I checked because im having problems with extrusion all of a sudden

#

Cyan PLA

shy kelp
#

Could it be from retraction?

south elbow
#

I honestly have no idea, the fan covers it all when printing

#

I was actually trying to print a mount for the fan so it can be installed above when it started stuffing up

shy kelp
#

What printer is this?

south elbow
#

Anet a8

shy kelp
#

No idea

#

My guess is something having to do with retraction

#

Ask @weary lichen

south elbow
#

Ok the powder on the side is actually just dust blown in by the fan

shy kelp
#

Oh lol

south elbow
#

Cos its all in the fan heatsink for some reason

shy kelp
#

That's weird

#

Is the dust filament? Or is it just random duat

south elbow
#

So reading a thingo online, these little shard things are from the extruder grinding on the filament and they might have gotten into the tube blocking it

shy kelp
#

Makes sense

south elbow
shy kelp
#

Wow

#

How do you plan on. Among it so that doesn't happen again?

#

Just a dust cover when not in use?

south elbow
#

Idk cos the room is fairly dust free. But i guess i could get some paper or something and stuff it in the gap

shy kelp
#

That's kinda strange

south elbow
#

I think all my problems come down to the bowden tube. Ill clean that and see how it goes

#

And find out why its grinding

#

And find out why an absurd amount of dust is being blown in

shy kelp
#

What is the bowden tube? I don't even have my own 3d printer yet lol

south elbow
#

I meant throat tube

#

Apparently its not a bowden tube

shy kelp
#

O

south elbow
#

There is also some wierd black crud coming out of the top of the heat block, probably burnt filament but why tf did it come out

shy kelp
#

Yeah that's real weird

uncut ledge
#

can't even print above 30mm/s with the wonky af setup I have now, need to find a more appropriate extruder motor 😔

weary lichen
#

@south elbow weird black crud on the top of the heat block? That sounds like heat creep to me.

#

As for the dust, I've heard that some people put a small amount of oil on their filament/in their bowden tube to prevent dryness/chafing.

south elbow
#

After pulling it apart, theres black crud all through the threaded parts that go in the heat block and i dont have anything (i dont think) that can clean it.
A few weeks ago i pulled it apart because i thought the nozzel was blocked (which i blow torch cleaned) and after puting it back together it leaked everywhere (cos i didnt know it had to be tight n stuff) SO i cleaned the plastic off the threads to the best of my ability by heating it up and trying to scrape the plastic out. but i guess its all charred in there and stuffed it.
So i think ive just done a few too many things wrong and am gonna buy a new heating assembly so i dont have to clean it all to fix the blockage.

#

another thing wrong is that the 'atomic' method of cleaning doesnt work, and i can not get filament out of the tube. it always gets stuck right at the opening for some reason

#

but i dont even know that the thing was blocked in the first place, filament comes out when you manually push it through. Just the machine cant get it out when its running for some reason

#

god ive rambled

#

TL:DR black crud all up tube from botch clean job prior, filament wont come out tube (but goes in fine), guessing its a blockage making it not print properly, dont have cleaning equipment, buying new assembly to hopefully fix

weary lichen
#

Definitely sounds like heat creep. The filament gets heated further up than the nozzle and expands to larger than normal size, so it can't be pulled up. Heat creep can be caused by incorrect assembly and is a giant pain to clean

shy kelp
#

@weary lichen you at home?

Oh, hey. West Chester's not that far from me.

For the wifi file upload, I just need a SD card in the printer?

Just keep the SD card in the printer

And it downloads the file onto it as cache.gc

shy kelp

Does it have to be blank? I only have 1 which I use for my Raspberry OS

I would not recommend using the one you use for your Pi

#

Would it work? Probably.

#

Would it screw over your Pi's files? MAybe, who knows.

#

The V1s and V2s have, IMO, a dodgy repuation for SD cards. A lot of people say it's the SD card that has the issue, but having fiddled with a few hundred SD cards for various things, I'm more inclined to say the printer doesn't treat them as well as it should.

#

But people have come across issues to which the solution is to reformat the SD card.

shy kelp
#

Rip

weary lichen
#

You don't want to have to reformat the SD card you use for your pi

shy kelp
#

Well guess I'm not using my Pi anymore

weary lichen
#

That said, the SD card that came with my V2 has worked just fine so far.

shy kelp
#

Does the printer destroy SD cards? Or just glitches while reading them?

weary lichen
#

And it doesn't need a large one, so you can probably get a <1gig one for dirt cheap somewhere.

#

Glitches while reading.

#

It'll stop mid-print, from what I've seen

shy kelp
#

Is there a fix?

weary lichen
#

Formatting the SD card is the go-to fix for it from what I've seen

shy kelp
#

I mean for the printer

weary lichen
#

Not that I've seen. Pretty much everyone blames it on the SD card, which could well be true.

#

I'm just skeptical of that claim.

shy kelp
#

I have a 32gb perfect SD card so if something goes wrong I'm blaming the printer

weary lichen
#

Seems perfectly fair to me

shy kelp
#

I'm tired of waiting, I want my printer yesterday

weary lichen
#

That is totally understandable

shy kelp
#

So besides the 20mm calibration cube what are some good things to print first

#

I heard people say to print a copy of the spring loaded thing since they say it breaks easily

weary lichen
#

Calibration cube is a good one

#

Platform Jack [Fully Assembled, No Supports] found on #Thingiverse https://www.thingiverse.com/thing:925556

This functional platform jack prints fully assembled without supports.
UPDATE [7/21/2015]: We have uploaded an updated platform jack with stronger scissor arms, improved axles to stop the arms from separating, and a larger gap between the screw and crossbeam to fix the fusing issue. We printed the updated version with a 0.3mm layer height and 15% infill in 4 hours.
UPDATE [7/22/2015]: For anyone having problems with the scissor arms fusing together we have uploaded a modified file with the tolerance increased from 0.5 to 0.65 mm (The axle tolerance is unchanged).

#

I want to print this lol

weary lichen
#

Friend of mine printed that. It's pretty neat

shy kelp
#

Raspberry pi zero?

weary lichen
#

The jack, that is

#

Yep! Zero W

shy kelp
#

That's a cool case

weary lichen
#

It's part of the Christmas gift for family.

#

Yeah, I've been tweaking the design for the past few days

shy kelp
#

Nice

weary lichen
#

Now to design the top piece, the bit that'll hold the APA102 LEDs

shy kelp
#

Oh

#

Could I print water tight cases with this printer?

weary lichen
#

Watertight will require a gasket of some sort.

#

Can PLA be printed to be watertight? I believe so, although it might require some heat treatment.

#

It's not something I've looked into much

weary lichen
#

LED holder mostly done

#

This print ended up looking like crap on the outside, so I'm testing printing the other way

#

I also need to add buttons to the top as well.

shy kelp
#

What is this going to be?

#

And why does the Pi zero w have 2 micro USB ports?

#

One is power, one is data

#

The one closer to the middle os used to power the device only

#

The other one can be used to connect usb devices

weary lichen
#

@shy kelp You've got them flipped. Interior one is USB, exterior is power. But aside from that, spot on

#

As for what it is, each of those holes will have an LED

#

There will be four devices

shy kelp
#

My bad, thanks for correcting that.

weary lichen
#

And each will have its corresponding LED. Buttons will allow each individual unit to change its color

shy kelp
#

They should be labeled on the PCB anyways

weary lichen
#

This will go via the InterTubes so that each unit will display all units' colors.

#

I'm giving one to my parents and one to each sibling/family group.

timber niche
#

@shy kelp @weary lichen PLA is hygroscopic, by the way, so I would avoid water. That's why PLA should be stored in an airtight container with dessicant.

uncut ledge
#

this is true but most PLA is pretty water tolerant

#

if you dont live in anywhere particularly damp or tropical its fine to leave out

#

i get more issues from leaving it unwound and snapping under stress, lol

weary lichen
#

@uncut ledge I think @timber niche was more referring to the question of "Can you print waterproof things"

uncut ledge
#

ahh, yes, i can't read too well

weary lichen
#

There was a bit of conversation between then and now!

uncut ledge
#

no idea tbh

#

watertight sure idk about waterproof

weary lichen
#

If PLA absorbs water.... you shouldn't attempt to print water-things with it.

uncut ledge
#

lacquer or polyurethane 👌

shy kelp
#

So since pla absorbs moisture, how should spools be stored?

weary lichen
#

As dryly as you should.

#

You're in Texas, right? You shouldn't have much of an issue

cobalt quarry
#

@weary lichen Nice Pi0 case. I wouldn’t mind printing a few of those as an early printing project.

weary lichen
#

I'll upload them eventually

timber niche
#

@shy kelp @weary lichen
Yeah, I should have clarified that I was refering to the earlier conversation about whether a water tight enclosure could be made from PLA. PLA can absorb water. Of course, feel free to do your own tests to see to what extent that affects a printed part. It may well be possible to coat PLA in something to make it waterproof. One thing about PLA is that it doesn't react much to common solvents. Ethyl acetate has a little bit of an effect on it, but to much, much less of an extent than the effect of acetone on ABS. So there probably wouldn't be too much risk of a sealant disolving the PLA.

I saw the discussion on Slic3r for the MP Mini V2. Then I spent way too long on the Slic3r website. Totally unsaid, but I gather it only runs on Intel/AMD architectures under Win, MacOS, or older Linuxes (e.g., Debian Wheezy or Jessie... not Stretch). No ARM (RPi) support???

#

Another topic... does anyone know if there are recommended preventative maintenance procedures for my MP Mini V2, and if so where do I find them?

weary lichen
#

@trim sail Look up the bed rewire.

#

That's the most important and significant thing that'll need to be done eventually

shy kelp
#

Bed wiring is also an issue on the v2?

#

@weary lichen whag exactly is fixed or new on the v2?

weary lichen
#

I believe it's mostly driver board updates

#

The control knob on the V2 is apparently much, much better than the one on the V1

#

Ah, the V2 has a better bed surface, a (better? Existing? Not sure) cooling fan, and an improved hot end.

#

Those are all things that can be improved/replaced/upgraded as you go, and a lot of people have done so

uncut ledge
#

it needs a mosfet for the bed

#

the board is an example of wishful design

#

its not really cut out to push 200w of power

weary lichen
#

200W... eesh

uncut ledge
#

mosfet, real belt tensioners, z braces, and microswiss hotend and it's a very good printer

weary lichen
#

I have to say, the V2 is a solid printer from what I've done with it

shy kelp
#

Why does PLA smell like pancake syrup lol

trim sail
#

PLA is made from corn (or so I've been told). Last Friday I did a lot of 3D printing. Saturday morning my MP Mini V2 just wouldn't fire up. It took several power cycles over an hour or so before it was back to normal. Maybe the corn fermented, and the poor thing was hung over.

shy kelp
#

Lol

shy kelp
#

@weary lichen

#

Finnaly

weary lichen
#

An only-slightly-late christmas gift!

shy kelp
#

Yep

#

So

#

I should first level the bed right

weary lichen
#

Absolutely

#

It should be to the point where you feel some resistance from a sheet of paper between the bed and the nozzle, but not where you need to use force

shy kelp
#

Lol the seller just messaged me an he said he forgot the spool holder and sent it today

#

Alright

#

Can I print without a spool holder?

weary lichen
#

Maybe?

#

I've never tried.

#

Can you improvise one?

shy kelp
#

I'll try to

#

Let me get the bed leveled 1 sec

#

Bed is leveled

#

How do I set up the wifi for uploading files?

#

Needed up luxky

#

Found the holder in the box

#

Also came with an SD to micro SD card adaptet

weary lichen

#

@trim sail There's an old joke about a preacher that was interviewing for the pastorate of a church. While having dinner at the home of one of the deacons, he was asked if he would like some corn and absentmindedly passed his glass instead of his plate. He didn't get the job.

shy kelp
#

Should I pre heat extruder for loading filament?

weary lichen
#

Yep

shy kelp
#

220 good?

weary lichen
#

PLA? Too high.

#

I print at 190-200

shy kelp
#

I'll heat to 200

timber niche
#

If your filament gives a range of temperatures, start near the bottom of that range. The filament I buy from Microcenter has a sticker on the reel with the temperature range on it.

weary lichen
#

I tend to feed it manually until it comes out the nozzle, then use the controls to pull it back a step or so.

shy kelp
#

Now the y axis won't move up, is it supposed to when pre heating?

weary lichen
#

Preheating only heats the nozzle.

#

The Z-axis (Up/Down) can't be force-moved. There should be a thing somewhere in the controls for moving it.

shy kelp
#

Well now it eorks

#

Plastic went trough successfully

#

Am I ready to print something?

weary lichen
#

Sounds like it

shy kelp
#

I'll print the 20mm cube

#

So once is slic3r, do I quick slice and save to SD card?

#

I mean

#

Exposición gcode?

#

Export**

weary lichen
#

I've never used quick slice. Export G-code is where I go to.

shy kelp
#

Alright it loaded successfully

#

Should I go to home axis or will it do that on its own

weary lichen
#

That's part of the gcode normally

shy kelp
#

Forgot to level one of the corners lol

timber niche
#

You can search thingiverse for "bed level calibration" and find lots of flat items that can help you see if it is printing evenly across the bed.

shy kelp
#

I just noticed

#

Wow lol this is the dumbest mistake ever

#

I never leveled the bed

#

None of my screwdriver bits fit

timber niche
#

Look under the bed, there are probably finger tightenable knobs for leveling.

shy kelp
#

Nop

#

It's some plastic thing

timber niche
#

And, if all else fails, read the manual. 😛

weary lichen
#

If the bed is like the V2s, you'll need a hex bit for the four corners.

shy kelp
#

Found a bit lol

#

Lol the knob is so unc

#

Uncomfortable

#

Why are controls so delayed lol

#

Alright should be leveled now

weary lichen
#

Oozing out?

#

Heat too high is often the culprit for me.

shy kelp
#

I mwan

#

When I start the print it just y ticks to the nozzle

weary lichen
#

I'm not sure.

timber niche
#

Maybe lack of bed adhesion.

shy kelp
#

Lol having so much trouble leveling bed

timber niche
#

It's probably a good idea to go around twice when you're first getting the hang of bed leveling.

shy kelp
#

How much force should it take for the paper to move

#

It doesn't want to stick to the bed

timber niche
#

It's a bit of a judgement call. I'd say when you can feel a difference in sliding the paper, you're there.

#

Does it have a heated bed?

shy kelp
#

Yeah but it doesn't work

#

I have to fix wiring

#

I'm going to put it super close to the bed to test

timber niche
shy kelp
#

It's starting to work

#

The filament is actually sticky and forming a square

timber niche
#

If your slicer has an option for a skirt, use that. It will print a box arounnd the outside of where the object will be printed that will help make sure the filament is extruding properly before attempting to print the object.

shy kelp
#

I'll check, thanks

#

What should I use for these parameters

timber niche
#

I'd try it with those settings. That's probably good.

shy kelp
#

Got it to work :D

#

Is there a way to see estimated time?

#

Only shows percentage

timber niche
#

Probably not on the printer itself. Your slicer might make some guesses as to time frame.

shy kelp
#

So the print looks chopped

#

How can it be fixed?

timber niche
#

Not sure. I can't see to clearly exactly what is happening there.

shy kelp
#

I'll take a pic when it's done

#

It looks half way done

shy kelp
#

I fixed it

#

Changed infill to 40% instead of 15%

#

And the settings I was using had the filament size wrong

timber niche
#

Cool. Yeah I was wondering if it could be an underextrusion thing. If it was set for larger filament it could have been underextruding.

shy kelp
#

So is PLA supposed to avoid contacting water at all times?

#

I was thinking of printing this but and bolt I need but the nut is going to be underwater

weary lichen
#

@shy kelp PLA is not the best for water

#

It works, sometimes

#

But I wouldn't rely on it because it's only "Sometimes"

timber niche
#

There may be a way to waterproof it.

weary lichen
#

@shy kelp What sort of "Underwater" is it going to be?

shy kelp
#

What do you mean?

weary lichen
#

Where do you need to use it?

shy kelp
#

Inside a pool

#

About 4 feet down

weary lichen
#

Hmm.

shy kelp
#

Well not pool

#

Like a pond

#

Not chlorinated and doesn't have any additional chemicals

weary lichen
#

The water itself isn't the problem, according to that link. PLA will absorb water, but it's the other things that cause issues.

shy kelp
#

What about maybe coating the 3D prints with the clear nail polish protector?

weary lichen
#

Which in a pool shouldn't be an issue, but a pond probably wouldn't fly.

#

That could work.

#

I've never tried it though.

shy kelp
#

What would affect it in a pond?

#

Bacteria eating away at it or something biological?

weary lichen
#

That's exactly it

#

At the end of the above link, there's this:

#

PLA will absorb water, meaning water molecules diffuse between polymer chains causing volumetric swelling. PLA will NOT be affected otherwise by pure water. When in the presence of certain compounds that are in soil, the polymer chains actually degrade into smaller and smaller pieces until they are (approximately) tetramers (4 monomers). At this size, the PLA can begin to be eaten by microorganisms in the environment causing it to compost. So unless these chemicals are present in the environment that the PLA is in, it will not be affected other than swelling, which can be remedied by drying it with desiccant in a box or through heating to a low temperature (<50C) and letting the water evaporate out naturally.

shy kelp
#

Oh

#

Thanks, I'm going to try the nail polish protector thing

#

So far the printer is working perfectly, no problems

weary lichen
#

You mentioned the knob was terrible, right?

#

There's many designes for knob improvements on Thingiverse. Might want to print out one of them for a good functional print

shy kelp
#

Yeah saw, them

#

Oh also, comment on your slic3r settings @weary lichen , you had the filament size to 3mm that's why my test cube came out all squishy, I s hanged it to 1.75 and it came out great

weary lichen
#

My filament is set to 1.75 locally, I'm guessing it didn't copy that over.

#

You'll probably have to tweak certain settings for your printer anyway. I usually run at 30% infill. Except for things like gears, then I go up to 75% or so

shy kelp
#

Word you recommend printing spare parts for this printer just in case?

weary lichen
#

It's not a bad idea

#

Especially as you can use it to check printing accuracy and see if things need tweaking

shy kelp
#

Why does everyone always 3d print a boat as a test? I think it's called bench y? What's the big deal about it?

weary lichen
#

It's a known quantity.

#

Everyone knows how it should look

#

It also incorporates certain design things into it.

#

IE, overhangs, bridges, etc.

shy kelp
#

Oh ok

weary lichen
#

Putting up pictures of said boat can allow for easy guidance on how to adjust settings for your machine.

#

That said, I've not done it.

shy kelp
#

Neither have i

weary lichen
#

But hey. Whatever floats your boat.

shy kelp
#

Lol

#

Currently trying to print the nut and bolt I was talking about

#

Really wish the printer had an ETA time thingy

weary lichen
#

This can tell you an estimated time for printing

shy kelp
#

Is there some way that I can make the LCD display show time instead of percantage?

#

Or have slic3r give an ETA?

weary lichen
#

Not that I'm aware of.

#

Slic3r doesn't do times, AFAIK

#

I use the linked gcode tool to figure out roughly how long it'll take

shy kelp
#

Is it very accurate?

weary lichen
#

Ish.

#

It says one of my prints should take about 1 hr, 40min

#

It took slightly over 2 hours.

shy kelp
#

Good enough for me

weary lichen
#

When I used Cura, I knew to add about 50% more time with what Cura said it would take.

#

For Slic3r and the Gcode viewer, it seems to be about 20-25%

shy kelp
#

Oh ok thanks

trim sail
#

I just installed Slic3r this afternoon. It defaulter tp 3mm filament. Probably a software feature (bug).

#

OBTW the slicer time estimates are like asking your programmers how long it'll take to do X. After a while you come up with a constant (finagle factor) for each engineer that you multiply their answer by to get close to real.

shy kelp
#

Lol I see what you mean by wifi upload is slow

#

I was playing around and it took 10 minutes for a 500kb file lol

@shy kelp What sort of location do you have the WiFi in? Mine's slow, but not THAT slow

shy kelp

Probably hardware limit then.

I'm heading out for the night. Have to be awake in about five hours, so I can't do much. Wha'ts up?

shy kelp
#

For some reason all of a sudden prints are starting to stick to the tape

#

It's gotten to the point where I have to change the tape each tike

weary lichen
#

Blue tape is, if I remember correctly, only good for a few prints. That said, I've never used it.

shy kelp
#

Is having a glass bed good enough to never need tape?

weary lichen
#

From what I've seen, it's typically glass with some hairspray or a glue stick.
