Print Z-PETG on M200 Issue

My M200 prints really well with Z-ABS, Z-ABSv2. I had troubles printing with Z-PETG though.

With the default settings for Z-PETG I first had extruder skipping noises like discussed here:
(Troubleshooting: Extrusion Problems in 3D Printers | Zortrax Support Center)

after that I checked everything, cleaned the nozzle and hotend but my prints turned out like this:

I replaced hotend, nozzle, thermocouple and heater but issue persists.

Any ideas?


Did you take down the side covers while printing with Z-PETG?

Also check if your fanshrouds are in good condition and fans are working properly.

Best Regards
