The problem is when you go to N300 and just set that as the next statement you have not established your X coordinate. You need to do RUN FROM HERE, not sure if they have that in KmotionCNC, I have that on my bigger machine. Are you running the MACH3 front end of just Kmotioncnc?

I run this code with no problem in KMotionCNC. But when i try to cut only one hole, for example start from line N300 , by means of "Set Next Statement" i get the error "Radius to end of arc differs from radius to start" and the program stops.

How can i cut whatever hole i want in this program.

Regards.

Thank you for the reply.
No just KmotionCNC, no Mach3.

hello g.astras,

I was having the same problem. the issue was just what the error stated "beginning and end of arc were not exactly the same" Tom added a tolerance parameter in kmotioncnc that fixed it. its in the lower right corner of the trajectory planner screen (Tool Setup > Trajectory Planner). I set it to .005 and haven't had an issue in 6 months.
