I suspect the X-axis driver may be over-heating a little bit... https://files.facepunch.com/forum/upload/132319/5109d9df-755e-4ce5-8ea8-6830490aaa8a/20180730_025447.jpg The one on the right was printed first, only shifted the top 5-10 layers or so, it seems. But the second one was much worse. Kinda neat that it shifted right at the top of the X/Y, though. Guess I'm gonna have to print a different enclosure for the electronics now. Currently got an 80mm fan kinda propped up in front of it but it just looks tacky as hell. But at least the print quality is nice right up until the layers shift.
Are you sure your belts are tight enough? I had very similar shifting on the same place on the cube.
Belts are perfectly tight. Here's the same Gcode with an 80mm fan blowing on the board: https://files.facepunch.com/forum/upload/132319/26832dd3-d869-4683-8723-b4e173f6cba9/20180730_090135.jpg
Made a fancy RAM holder for a friend in IT Gonna print a bunch. http://puu.sh/B6xQL.jpg
I printed off some Dark Souls characters - the Elite Knight I found on Thingiverse, the pyromancer with a zweihander I made myself. I had a few issues printing the second one; the one-part model was a bit short and the sword experienced some glitch effect, I guess the print head overheated or something. The bigger print I split in two at the waist, but for some reason it failed the first time and stopped printing the lower half just a quarter of an inch or so away from the top. https://files.facepunch.com/forum/upload/236919/882a2384-7d8e-44f2-b92b-8747a951d969/image2.jpg https://files.facepunch.com/forum/upload/236919/f2c244a6-9727-4858-a3b2-5a0255616be4/image.jpg
Decided to finally get my printer up and running again after it got clogged up a few months back, threw a 8 hour print at it out of the gate. https://files.facepunch.com/forum/upload/164/3790ce34-a0db-4ecb-a9b0-d1463e4ddb21/2018-08-02 17.55.51 - Copy.jpg Looks like it's ready to go.
Gonna put more lipstick on the pig this weekend. Got some new nozzles, wires, yellow PLA+ filament (for printed upgrades), a new bed carrier that isn't made out of wibbly-wobbly timey-wimey bullshit, a BLTouch probe, and an E3D V6, also going to pick up a sheet of glass from the hardware store tomorrow.
I'm seriously having problems with starting prints, filament sticking to the nozzle making a huge mess and not sticking to the surface in general despite having a heated glass bed. I wonder if calibrating will help, barely read into this oops.
What material are you attempting to print? Certain materials stick better on certain bed materials/adhesives. Also...[inconspicuous whistling goes here] https://files.facepunch.com/forum/upload/132319/e34c194e-fccc-4424-aa5b-c76715f59581/20180803_020646.jpg https://files.facepunch.com/forum/upload/132319/d4bf8f7c-45d6-497a-a6f5-0c9fb98cca9d/20180803_020713.jpg
I'm currently printing with the black PLA the printer came with which worked really well at the beginning but now has trouble sticking. I'll try a few things later because today I want to try the 0.2mm nozzles that arrived weeks ago but was too lazy. Also I have to design a case for a LED controller that I've made with the ESP32, that will be a pain in the ass.
Cleaned the bed and nozzle with some alcohol and now it's just like on day one, nice. Now I have to figure out how to use the new nozzles, especially the 1mm one. I've heard that one is a lot of fun to print huge stuff with which this printer is made for anyway.
Holy shit. Replacing that bed carrier with the aluminium one has practically made this piece of shit into significantly less of a piece of shit. I can actually level the bed manually now without it wobbling itself out of alignment if I so much as look at it funny.
When it comes to levelling, I always level over-tight on all surfaces. I designed and 3D printed some simple "level lockers" to acts as lock-nuts for my bed levelling. M4 sized holes that lock the levelling knobs in place. They actually seem to do a good job! I've just discovered a way in fusion to wrap models around a cylinder, so I can make sweet bracelets for people. https://files.facepunch.com/forum/upload/703/23e906cf-ce4a-40e3-8f06-9b04bf785c77/image.png https://files.facepunch.com/forum/upload/703/a7dd3d66-38fa-4255-9a1f-685288b70325/image.png
Gave printing the lizard another go at a much larger scale, and with "Linear" supports rather than "Tree-like". Put a raspberry pi and a webcam onto it aswell for a bonus bad angle timlapse: https://files.facepunch.com/forum/upload/164/998558c3-9643-4913-a70d-2ad2c8dd8d33/lizardprint.mp4 https://files.facepunch.com/forum/upload/164/01a400ed-31c0-457c-af80-5de6e5bd3b91/2018-08-04 19.07.02 - Copy.jpg https://files.facepunch.com/forum/upload/164/dcc12824-0f24-4d99-a173-1cef941f35ff/2018-08-04 20.51.47 - Copy.jpg Success! I sure am liking Linear supports a lot more, a lot less accidental snapping off the model's parts, a lot more to clean up though I guess. Might also be time to invest into a dremel and such so I can clean up the model a bit better, only so far I can get with scissors and the included "chisel".
eSun "white" PETG: "Sure thing, boss! I'll stick to that painter's tape like you wouldn't believe!" eSun black PETG: "Is that a shitty 'PEI'-like bed liner? Fuck yeah I'm all over that shit!" eSun yellow PETG: "lol no"
the .2mm nozzle is the best, leveling the bed everytime I change the nozzle is going to be annoying though. Wish there was a better way. really want to try the 1mm nozzle now but I don't know what to print with that.
If you have clear plastic, try doing some vase mode stuff with the 1mm
I do, will try some laterrr
Finally got the yellow PETG to stick worth a damn The secret: 1) Raise nozzle temp to 245C 2) Lower Z-offset to -0.6mm 3) Slow it waaaay the fuck down on the first layer https://www.youtube.com/watch?v=p4V5AGo67WE&feature=youtu.be
And then the extruder jammed. :/
Attempt #2: Print came out, everything stuck to the bed nicely (perhaps TOO nicely, had to squeeze an X-acto blade under some parts to get them to come loose), but now I have this issue: https://files.facepunch.com/forum/upload/132319/9e754a98-1b22-481c-a9a0-01b3865406d2/20180809_230204.jpg
isn't that caused by inconstant filament supply? also I'm at my limits here, I can't get this stupid part to print properly because the nozzle keeps accidentally taking already printed lines with it during travel which is so damn annoying because the holes in the part I want are like 3mm in diameter. I might just give up with this one as it's already giving me a headache
Is that for the first layer? I was having the same problem with this yellow PETG. I had to lower the nozzle and slow down the print-speed to get it to stick.
I'm guessing it's only for the first layer. I'm using the normal black PLA that came with the printer which worked fine pretty much all the time. It's just now that the gcode for some reason traces over the already printed lines, so instead of just going straight to the wanted point it traces over the printed material which is thanks to the 0,2mm nozzle super thin and gets easily picked up by the nozzle. I also found out that turning the fan up on the first layer just blows the material away, was funny to look at but didn't help me get any further. I just told my dad the print has way too fine detail to even get it started so hopefully he won't bother me with that, it's not like the part is of any importance anyway. Sometimes I feel I should never tell anyone what I'm good at just so that no one would bother me in the future with stupid shit that will not only annoy me because I have to do 100% of the work but also them because they will only later find out that what they wanted wasn't actually that great of an idea, which would be already too late because I would've wasted all this time for nothing then. this pisses me off so much
About the only things I can think of are: Clean the print bed Adjust nozzle height (unless other prints with that nozzle diameter are turning out just fine) Heat the bed to about 35-40C Try a sheet of glass (I hear PLA sticks pretty well to glass) Other than that, what are you trying for bed adhesion? Clean bed, blue tape, glue stick?
idk if I've posted my printer here before but I have the anycubic i3 mega which has a heated glas bed. I've tried 1 but dunno if that changed anything, had to do 2 when I swapped the nozzle aka I adjusted the bed height, I might give 3 a try but the bed usually heats to 50°C which is the default which has worked so far, 4 is is build in anyway which also has a pattern that helps the material to stick better, 5 worked somewhat but 6 has to hopefully do the trick. I'm following the instructions that came with the printer, that is to just start printing which has worked good.
Damn the glue stick method is rather messy but hey now it prints the first layer just fine, but maybe it had also to do with me setting the speed to 60% on the printer. Heh
I always use glue stick on the glass bed of the FlashForge Finder, I've never really had a problem getting anything to stick with pretty much any settings though. Anyways, since it's a removable bed I just take it off and clean it in the sink now and then. I use the sort of glue that shows up as purple when it's wet, so it's super easy to see where you need to clean. I imagine that for fixed beds, it's pretty easy to just use a towel now and then.
Shit, I ruined my printer. I shouldn't have used the super strong one but that's all I had. https://files.facepunch.com/forum/upload/483/561b3cd1-bce6-4037-a5f8-3dabd823c326/20180811_203047.jpg But not all is lost because my dad is satisfied with the print despite it being absolutely awful in both design and usability which I called out for him but nah.
Oh god, what did you use?
