Alice Averlong🏳️⚧️I have resumed the folly of 3d printing after a nearly year long hiatus
place your bets until how long it'll be until I'm ranting about how printers are a sin against man and god
crashed my slicer
I'm printing a calibration cube because I don't know what state I left this printer in.
presumably in the standard state of "it kinda works but I don't trust it"
crashed my slicer again
and again
and again
third attempt worked.
I probably should have updated octoprint before hitting go, and I probably should have done some manually leveling, but hey, it seems to be printing so far.
also the filament has been sitting in a garage, loaded into the printer, for a year.
it's probably really shit by now. as soon as the cube finishes I'm gonna need to swap to something, anything, else

there's a lot of work that can and should be done on this printer, but it's all gonna be limited by the fact I can't stand up for more than 5 minutes
well, there's something going on with the z-axis, but it printed more or less.
I've also got to switch to a different power supply for the pi that's running octoprint, and upgrade the pi to a new OS (which requires backing up and restoring existing octopi settings) because my python is EOL.
so it's working, but I'm still sighing a lot
anyway I loaded new filament and I'm printing a chep cube again!
okay I printed a CE5P calicat after attempting to fix the z-offset issue. It still is horrible.
possibly this is mostly a temperature issue: I'm using the stock temperatures but I think I upgraded this to an all-metal hotend that needs to run higher?
reprinted with higher temp. it's better, but still bad.
so probably there's another issue. I remember I did a lot of rebuilding of the hot end in the final days of using this before, so who knows what's clogged in there?
I printed on a raft because the z-offset is still fuckt
a higher temp (220°C) and 110% flow rate seems to be working well enough.
Phil Nelson@foone Looks like an extrusion issue to me, yeah
michel v@foone I would recommend doing calibration prints with https://slic3r.org/, it shouldn’t take much time and it’ll help you get a working profile. (One of the calibrations is about extrusion rate, which may need adjusting here.)
makkin thing@foone any chance this is a creality printer with the stock extruder assembly? Random underextrusion could be caused by the plastic extruder arm cracking (common failure)
@gbrnt it is a creality (ender 5 plus/pro, I don't recall which) but I believe I've replaced the extruder hardware

Plan A to Y@foone a few random things that might help:
-gently tug the filament line to make sure that it takes as little force as possible to pull it off the spool
-check the extruder tension (haven't seen what kind your printer has but there should be some kind of idler gear)
-bump up the extrusion multiplier a few percent if none of that works
-If the Z level is too low it can create what looks like a clog so maybe try raising it higher than you'd think? I dunno, that depends a lot on how you have been calibrating it.
-Printing a flat 1-layer square to check how much it's squishing the filament is probably the best way to test Z axis calibration
Edit: also it's possible it's that the room is too cold or the filament is old. I've had prints like that because of those two factors

Kranston@foone i dont know what those rings around the print are for, i assuming that they're an extra way to make sure the print bed is level. but it makes me think that the printer is making a summoning circle to conjure the print lol
Michael Cook@sudo_EatPant It’s a border. Mostly I think it just gives the extruder more time to prime and get flowing before the real action starts. Otherwise the first few mm may not extruded well if it didn’t fully self-prime.
I love thinking of it as a summoning circle though! That’s great.
@sudo_EatPant yeah they're a summoning circle. 3d printing is forbidden magic
Bits&Terminal Jeff@foone You may need to dry that filament. A food dehydrator running for a few hours would probably do, but an oven that can be set at 120F (140F is a little high but would do) (not C!) for a couple of hours can work as well at least for PLA.
Alternatively you can print with filament that is still vacuum sealed.
Note that at 140F in an oven the spool itself if in plastic may start deforming. Make sure it's on a cookie sheet (or other metal flat surface) and flip it upside down every half hour.
@jf_718 This red filament is brand new, I only unsealed it before doing these two prints
@foone Ah, in that case I'd bump up the extrusion temperature by 10C and see how that goes. Sorry, I read earlier in the thread that the filament had been exposed for a year but didn't realize it was another spool. My bad.
@jf_718 no worries. that's what I'm doing now, yeah: I bumped up the temperature to 210C and lowered the retraction distance a little. it's printing now
Jim P.@foone @jf_718 Unfortunately it's possible to get wet filament straight from the original vacuum sealed bags. They use water to cool it when making the filament, so it can retain moisture straight from the factory.
But this does seem more like something impeding the extrusion more than the filament itself since it seems to be somewhat consistent with both types.
Wouldn't hurt to do a cold pull/atomic pull to make sure there isn't a partial clog since it sat for a while.

The VHS Wizard 🦝📼🧙@foone X gonna give it to you. And by "it", I mean, whatever that is.
Kawaoneechan@foone Oh, I have one of those. Mine's blue.
It's kind of an heirloom from my dad.
@kawa your dad was a 3d printerer?
@foone He dabbled. I helped blender up some simple models for some of his projects, and he got me a green scale model of the #Asspull3X. Which is *slightly* peelable compared to the cube, Grogu, and prototype device faceplate, and the only green print of his that I have, so that's interesting.
I wonder who got his printer?
@foone I also wonder where the fuck the calipers he left me to measure out that device faceplate went off to. Should be *somewhere* in my apartment...
anna, a criticality incident at the gender accelerator@foone why i have no desire to get into 3d printing. 2d printing is bad enough
Stewart Russell@foone under-extrusion can do that

Graham Sutherland / Polynomial@foone ah, 3D printing. it's like being into denial kink without being into denial kink.
✧✦Catherine✦✧@gsuberland @foone it's kinda nuts how i've always experienced it like that, and my headmate just... sends a print to print, and it simply does the thing. unbelievable honestly
Leona Rainside@foone With this build quality, I see what the X box kerfluffle is about.

Clara@rallias I hate it when my dimensions rotate through the 4th dimension!
Renalia - #1 pizza downloader@foone that's probably slight delamination. Possible the head is calibrated slightly too far away from the print bed.
@foone ooh actually, I missed the warping at the bottom there. Possibly too CLOSE to the bed actually
@Nine that's after a raft, so I'm not sure it's indicative of bed issues. The calibration distance is likely, I seem to recall it's insane on this printer (you have to calibrate it on the touchscreen, then reverse-calibrate it in the gcode? something like that?)
@foone yeah my neptune 4 used to have this issue. I actually nearly destroyed an entire printhead before I realised the issue I'd caused by pushing the head too close to the bed. The rafts LOOKED fine but because it was too close, as it extruded, material progressively oozed up around the nozzle, causing slight adhesion of freshly printed parts to the nozzle as it moved, causing lifting in places as well as it pulled apart the still not fully set layers a little... Eventually I got the blob of death. Had to replace the whole printhead x.x
@Nine that sounds very likely to be my issue, yeah.

@foone Looks like underextrusion, which could be any number of things, but it could easily just be the filament degraded sitting there so long.
Argonel@foone @Argonel It tests more things than the cube does, and it's better than benchy for certain tests, but if you're just looking for a basic dimensional and flow test the cube is still good.
If you aren't yet interested in diagnosing things like overhangs and so on then I'd just keep running the cube until you sort out the extrusion issue(s).
The CaliCat is definitely cuter, though, and easier to pass off to people instead of throwing out.
