so, uh, anyone know how to get out a prusa mk3s brass nozzle that sheared off inside the heatblock while being replaced despite being torqued to prusa's specifications? asking for a friend

Sagebrush posted:And just to be sure, you are heating the nozzle up before trying to take it out, right? Because I don't see how you could have sheared the brass apart unless you tried to unscrew it cold, and you will have an absolute gently caress of a time getting what's left of it out if you try to do it again. The brand new one sheared while I was putting it back on. Despite using a properly set torque wrench. Maybe my torque wrench is broken. And yes, it was at 285. I'm just gonna replace the heatblock, and potentially break. Deviant fucked around with this message at 04:02 on Jul 20, 2021 |

Sagebrush posted:That's wacky. I'd double-check your torque wrench, definitely. And make sure you're not, say, accidentally using foot-pounds when you should be using inch-pounds. It's possible that you just had a freak bad nozzle but I've never seen that happen before. Their doc says 2.5 Nm, so I set my wrench to 22 inch pounds:  but i'll just use your method on the replacement. Garage edit: never buy a harbor freight torque wrench.

it's fine. i'll get it fixed thursday and have learned a valuable lesson. and maybe try an extractor to save the old heatblock/break.

welp, they laughed at the screw extractor, so i'm down until my new block and break arrive. let this be a lesson about properly calibrating and checking precision tools.

Ugh, I replaced the hotend on my prusa mk3, redid first layer calibration to look beautiful, and have a spotless and freshly washed build plate, and the front corners of my calibration cat are lifting. I'm starting to think this is a roll of dodgy PLA, despite being jessie transitional. Any thoughts?   he's being printed at default size, at 215/60 degrees. i'm trying with a roll of black hatchbox right now to see if it fares any better.

ImplicitAssembler posted:Did you redo your hotend PIDs? (That is a thing on Prusa's, right?) I did, recalibrated at 215. It also has a Temperature Calibration feature for the pinda sensor, but the one time i calibrated it and turned it on, i made air spaghetti, so i don't use it. The hatchbox test has only printed his little feet so far, but they appear to be sticking. I may have just gotten a dodgy roll of jessie transitional. More on this as it develops.

It's also harder to see potential warping on black filament, so i'll have to wait for him to finish to really compare the two. Edit: hmm, he doesn't seem to be any better. I think I'm gonna send this printer through a full refresh to eliminate any possible gremlins from firmware, calibrations, etc. https://help.prusa3d.com/en/article/full-system-refresh-original-prusa-i3_133258 i dont have a photo, but the angle of warp is about the same from the jessie to the hatchbox, so i think something about my settings might be off.

Well, I don't know if it was firmware cruft or just doing a full recalibrate, but cat appears to be sticking properly now.

so i'm now trying to see if printed solid will exchange this roll of transition PLA for me blue: jessie transition PLA, 215/60 black: hatchbox black, 215/60 identical gcode, similarly stored filaments. I think i just got a dodgy roll and it's been causing issues. at their suggestion i went up to 220 and it looks identical. someone else here said the quality of their transitional PLA had dropped off, too? If I have to go back to hatchbox, i will, but i will grumble about the price. Deviant fucked around with this message at 19:29 on Jul 27, 2021 |

Printed Solid's CS team has been stonewalling me on trying to exchange this roll of PLA I think is bad. "Try at 235. Lower your nozzle" dude, i've got a perfect print with other brands. just replace it. i can no longer recommend them as a vendor.

The roll is basically brand new and it's been lifting on prints since I opened it. I know of two other goons that are now having issues with their Jessie pla and I suspect something has changed or they sent out a bad run

Randalor posted:I know this is a dumb question, but if it's just the front feet each time, and it's always happening in the same spot on the printbed, have you tried printing it elsewhere on the bed and seeing if it still happens? If it's a heated bed, maybe the front feet are just in a cooler/cold spot. I've said most of this already but: - It doesn't happen with hatchbox PLA. - The bed has been cleaned repeatedly with dish soap - It's dead center in the bed, so I don't see how it could be a cooler spot. - It only happens with this roll of plastic.

It looks like the sunlu filadryer s1 took about 2g or about 2mL of water off the roll in 6 hours. I have to assume that's liquid volume, so we'll see if it prints any better.

I keep all my non-in-use rolls in gallon bags with dessicant, which has been fine. This roll was definitely moist directly from the mfgr, though.

I am at my wit's loving end with this printer. This roll came out of its bag within 5 minutes of this print.   i have tried a higher nozzle. i have tried a lower nozzle. i have run first layer calibration more times than i care to think about. i have washed it. the filament is in a heated drybox. i am using default prusaslicer settings. i do not understand the loving problem. the layers stick fine. it is JUST the support material that does this poo poo. i'm starting to think that i, or the printer have a screw loose. possibly both.

Deviant posted:Yes, I've gotten consistently inconsistent results on both sides. Okay, so my calipers only go to .1 increments, but I printed that and got 0.2, 0.3, 0.5, 0.7, and 0.9mm thick. ie -.1 the whole way across except layer 1, meaning i'm a tad too close? averaging that out we get -0.08. My sheet profile is currently at -0.850, so i'd want to tweak to what, -.780ish? am i parsing this right mentally?

Sockser posted:That’s right, yeah So here's my concern with that. I adjusted my Live Z from -.85 down to -.78. the reprint came out more accurately, at .2, .4, .6, .7, and .9, giving me an average of -0.04 However, even the -.78 version looks like it may have been a bit too far off the bed?  this first layer isn't very well 'squished together', to use prusa's words, and the individual strands seperate fairly easily.

Sagebrush posted:Incidentally, I notice you aren't having any adhesion problems with these layer test files and the same black filament. I was only having adhesion issues with supports when i started this mess. If i let it run long enough to try and lay down 'real' bits, they stuck just fine. but that still doesn't address the fact that this methodology seems to be making me back my nozzle out too far?

Well, a few tweaks later, and pulling my nozzle way further back than I thought, I have beautiful bottom layers and supports. Ended up at .775, which is way higher than i expected.

Sagebrush posted:Heyy nice. It's what I said in my first post. Having the nozzle too close can physically peel the traces off the bed. though I did tell you not to read that part so my bad i place the blame squarely on prusa's live z calibration feature. it tells you to look for squished lines, which had me going far too close (closer to 0.850)

So, the results are as follows on my stuff: - leveling my live z helped with supports - the transition PLA from printed solid is still definitely a little dodgy - they're sending me a new roll to try out, apparently they say they have made changes to their manufacturing process and would like me to review/report back. - i ordered a new steel sheet from prusa just in case my PEI is on its way out, if not i'll have it. But i'm still using hatchbox et al for anything critical in the meantime Deviant fucked around with this message at 17:32 on Aug 4, 2021 |

So I definitely got something new from Printed Solid they aren't offering yet and have asked for my feedback. It's labeled "Jessie 2.0", and I'm going to give it a try after i burn out what's left of my old stuff, I found settings that play finally, if only barely. Any suggestions for test/calibration/etc prints? After a temperature tower to see where it likes to live.
