I’ve noticed on some prints with a lot of circles and arcs that while the resolution setting for arc fitting can affect your ratio of G1 to G3 movements, it seems to have no effect on the tree support movements.
This is the inspection for where its drawing lots of tree supports with arc resolution of 0.02:
and this is where its printing the actual object, using an arc resolution of 0.02:
and here is with the default arc resolution of 0.012:
i’ve fiddled the numbers quite a bit but essentially, it does not seem to apply arc fitting to tree support movements, which is a large opportunity missed in my opinion in terms of print speed and noise generated by the printer etc.
thoughts?
I have also been troubleshooting the same problem. The machine is always going to sound horrible when going fast on that many small G1 moves. Like its grinding. Not many users on here understand Gcode but as a machine shop owner I can tell you there are HUUUUge improvements that could be done to the gcode output of these machines and hopefully they will be able to continue to improve things.
So I found the bug I think. You need to uncheck arc fitting and then recheck the box for it and slice again each time you change anything. It worked for me at any tolerance I set.
I also found a bug if using Orca slicer that if you set extrusion rate smoothing it will also disable arc fitting for some reason.
