Also, I have a few questions
5. Does anyone have a recommended print to help calibrate PETG first layer settings?
Oh boy, printing PETG... Now there is a wall I’ve banged my head against the past year.
The Prusa Mk3 is making things a lot easier! PEI with a THIN coating of window cleaner, in difficult cases a wide (10-12 rings) skirt to increase the surface area, 220-240/60˚C, and finally print s.l.o.w.l.y. , as the others say.
This way I’ve printed first layers that are between 0.18 and 2.1 mm thick, measured with calipers. Started out with 0.15 layer height and then add a tiny bit of nozzle height with Live Z.
5. > Yes, I read it in a forum here, but I’ve forgotten the inventor’s name unfortunately...
I make a massive 60x60x60 mm cube, slice it @0.15mm layer height and just print the first layer. Pick a first layer height of, say, 110% and see what happens...
Edit: Oh myyy, it just struck me, I have a 0.3mm nozzle on the Prusa! I don’t know how that affects things, but my guess is: increase all numbers by 30% for a 0.4 mm nozzle....
