Comment on Prusa MK3s+, PETG and a 0.6 nozzle
InattentiveRaccoon@lemmy.animal-machine.com 1 year ago
I got PETG working on my Mini clone by basically just switching to 0.6 nozzle profiles from the wizard and using the generic PETG profile.
But, if you’re new to PETG, know that it gets real moisture sensitive, real fast. Sounds pike you might benefit from trying try the filament out, check the web for more on that.
After making sure the filament was dry and that my initial layer is good, because changing nozzles means you need to fine tune the z offset again, I would print a retraction tower test and dial in retraction length settings.
That a good basic troubleshooting list.

Z was recalibrated already. I’ll try a 50c bake for a few hours to get rid of moisture.
Ordinarily, I’d expect to see evidence of bubbling/snapping at the nozzle as water boils out while laying down plastic. No obvious signs of that though.

Stringing and nozzle buildup are the general signs I get with petg being damp, extreme cases it’ll have noticeable bubble, I’ve found that I need to run 12+ hours at 54c to dry it sufficiently, even on relatively fresh spools depending on the supplier, age etc. I also recommend securing your spools if they’re paper based, had the adhesive melt on one and the entire thing fall to pieces, I just rewound it onto an empty plastic spool I had.
