Yep overhangs have been an issue with ASA since I swapped the HF nozzle in 2 days ago. I printed the same part twice, same profile, (only change was the HF nozzle) redone the entire calibrations including vision encoder plate. Only change was the nozzle, but the overhangs (45 degree incline) were really terrible afterwards. Even the outer wall speed was identical (60 mm/s). So I think it’s safe to say that the profiles for the H2D will need quite a bit of tuning to account for the different thermal properties of the nozzle.
Does anybody have a good ASA profile for the 0.4 mm HF nozzle?
