From time to time have been having issues with overhangs but never critical but worse than Prusa and today 3dsurfr reported an issue and tried to check it on my machine from curiosity and yes it is an issue and finally discovered what is the actual problem slicing . Googled and found this thread
Have found a couple of work arounds but not happy with the solutions . Changing the layer height on some models helps , but working with 0.2 is the common , I know that 0.12 and 0.08 most of the time solves it , also orca slicer has a nice feature as well which i think works always
Any one found a solution of the slicing in the air when the angle is above 65degress some times less with 0.2 layer height ?
My temperature profiles and filaments are very well tunned , so not related to fan, temperature for filament tuning , and pretty sure that 3dsurfr is an expert in that area as well.
