Re: Start from line - error: Radius difference too large between start and end of arc
I am betting the problem is the Z position at the start of the arc. I have ran unto this before when I have edited g-code during operations. If you put a G01 Z height command at the start of the arc that is the same height as the arc Z height, it should solve this.
Essentially, what has happened is the lines of g-code you commented out changed what the z-height of the spindle was when it reached the commanded arc. Now the arc move in XYZ is too large where before with a smaller difference in Z it could make the cut.
