New here, but have been working with a UM3 extended for several years at work. We have always just printed using ABS, however I am working to try out PETG. I have done several test prints unsuccessfully. I have the print bed at 85*C, and have tried printing at 235, 245 and 255*C at the print head. Started out at 80mm/s and also tried 50 mm/s. Layer height at 0.15, material is the UM translucent blue. AA 0.4 nozzle
Underlying issue seems to be the material stops feeding and is getting bound up which causes the feed wheel to chew up the filament and stop feeding. It seems to print fine for the first few minutes, then starts having issues after maybe 30 mins. Initially, I thought it was because filament wasn't getting hot enough, but at 255, seems like it should be plenty hot? Material feed tube is fairly new and hasn't had any issues feeding ABS.
Any suggestions?
