Ender 3 micro swiss issues w PETG

Petg doesn’t like being cooled too quickly. I print it with an enclosure and with out. That said the room the printer is in with no enclosure is around 30C. Far from cool. The enclosed printer air temps sit at least 40C + .

It is an easy thing to try. Drop the part cooling fan and maybe try a temp enclosure and see if that helps. I use pei on most of mine and pritt stick on the glass bed. I have never used tape. Tape will alter the z calibration. Pita.

my ambient room temp is more like 20 degrees which may be causing the issue. I will try to enclose it and see since it is only on petg prints that I am having adhesion issues. PLA and flexi pla print fine.

Try 230 on nozzle and 70 to 80 on bed with 40% fan for part cooling
