I have a problem with the jerky motion of my router.
I can only find Mach 3post processors in Sheetcam that outputs arcs in I and J commands.
I have previously, using other CAM software, always done arcs with coordinate points instead of I and J,and had no problems.
I have tried to force CV mode on using a G64 line in the beginning of the Gcode file, and the CV mode is showing green on the Mach 3 screen?
Can anyone help?
Regards and thanks
