My XL generally prints a little hot. I usually need to dial down the extruder temperatur 5 c° down. This seems to be a hardware thing. On my Mk3s that was not the case.

Usually it isn't a problem, but for some prints it is. You case is not an easy print because of warping.

Too me IT Looks Like you might a little hot and that shrinking ist causing Problems.
The Problem in the first picture might be because of partial disattachment from the build plate die to shrinking. But it is hard to say for sure.

Are you saying that default Prusament PETG settings in PrusaSlicer is wrong?

Hi All!

I'm having trouble with prints for quite some time.

This model is not so complicated. Slicer is PrusaSlicer 2.9.0 with pretty much all default paramters, 20% infill, gyroid.

Filament is Prusament PETG, freshly opened just before printing.

Any help is appreciated!

Thank you in advance!
