Hi, try this
Hello every one
I'm using FeatureCAM and Mach3, almost every thing is OK, except creating and arc or curve, it works great in the simulation, but in Mach3 I see the roughing pass is OK, but in finish pass I get one of 2 cases:
1- the arc become a straight line in finish pass.
2- the arc become circles.
Here I attache screen shot of the case, and Mach3 settings, also I attached the GCode, is it Mach problem or the post
