I'm testing out MeshCam 4 and it's kind of frustrating me. The part I'm cutting has a lot of flat areas and they come out looking great after roughing with a 1/4" end mill, then the "finishing" path comes along with a 1/8" ball mill and ruins the surface finish. I already have the ball mill stepover set to 0.02" (!) and you can still see the cut lines left by the ball mill.
I realize this crappy surface finish may be a result of a few thousandths variance in cutter length after performing a manual tool change, but if MeshCAM had the end mill cut the surface to the final depth already, then why is it wasting time running the ball mill over it? Come to think of it, CutViewer shows the crappy surface finish I'm experiencing in real-life so it can't have anything to do with my machine.
Is this a beta version bug or am I missing something?
