Basically the main problems I have:

  • Overhangs burbles when the overhang angles is 30 or higher
  • The bridge in the benchy is a disaster, there are a lot of filament delaminated an falling down
  • During the print some plastic is attached to the nozzle and dispersed over the plate
  • There are some artefacts in the surface and the surface is not smooth

I use bambulab PETG-CF filament. Flow Dynamic K = 0.35

Could anyone help me?

I’ve had issues with purple petg-cf when I’ve tried printing it with 0.08mm layer. Increasing layer to 0.16 helped in my case.
