Best I can tell, my z-seam after a hop is under extruding? I tried looking at all3dp’s troubleshooting page, but couldn’t find this specific issue. Can someone fill me in on the name of this so I can best Google it? I’d also be happy to take pointers, but I do try to be self sufficient.
That’ll be your retraction settings that need to be tuned. The pressure inside the nozzle isn’t getting high enough when starting a new layer. Took me a couple minutes to see the issue since it’s black and shiny. I’ve used http://retractioncalibration.com/ before to help get my retractions tuned
Hard to tell, but obviously your printer is struggling on layer change and/or retraction. Assuming its not play in your mechanism, Id fitst try printing just that part of the model without retraction and see is the problem gone. If it is, maybe you have too high retraction distance that can cause partial clogs. If the problem persist maybe you are overextruding a bit and then nozzle drags that corner out of the position. Tiny overextrusion can be a pain when printing “walls only” models. Its more guessing than anything, it would be useful to see your calibration models
I think you might be on to something with retraction. The open cubes didn’t show it with the solid corner. I’ll be able to print another test print tomorrow once the second copy of this print is done. I’ll make a smaller cup tomorrow.
One question, when I manually feed the PETG into the 0.8 nozzle, the filament feels… Gummy? Springy? Not at all like when I’ve typically fed PLA into 0.4mm. I wonder if the springyness is leading to weird retraction
You properly calibrated esteps? Also check your combing settings. I don’t think it’ll be that tbh, but there’s a chance it is
I’ve been meaning to do e-steps but haven’t got around to it. I did do a flow-rate adjustments which had me drop it to like 93%, which should compensate for any e-step issues.
I’ve not checked combing. Honestly never heard of it before this.
Whatcha making there? It looks like a shrews fiddle 😉
It’s a stroller cupholder for some dude on my town’s Facebook page. A 3d printing Etsy page wanted $35 for this, so I showed him how he can save money by spending $70 on filament, new nozzles, and a new hotblock (see my other post here). Overall I’d say the print came out well enough (🚢 🐿️) but I’m just curious on better settings for future prints.
How’s your humidity control?
