I’m having issues with PETG and overhang curling.
Is anyone here able to print PETG with decent overhangs, and if so, what settings/slicer are you using?

I’ve tried to decrease temp (down to 220) and also increase (up to 245) but that did not help. I’ve also tried to increase/decrease layer fan cooling (ducted) and that also did not help.

I’m having the same problems. And tried the same.Maybe more cooling?

I’ve been able to improve this issue a bit by:

  1. Decrease layer height, now at 1.6.
  2. Tweaking extrusion widths manually in slic3r.
  3. Lowering bed temp a lot (from 100 to 70)
  4. Lowering extruder temp even further, currently at 215.
  5. Use layer fan on max at all times.
