Hi

Im playing with toolpaths. Fusion 360 simulation shows correct, tool is getting to the center.
Also in Axis I can see lines in the center. But the result is this.
Any ideas where is the problem?

Are the overall dimensions correct?

What are the modal g codes for the program? You can see them at the bottom of mdi box in axis. Or the first few lines in the code itself. Is there a G64?

If so type in G61 and run the program again. This should make it follow the exact path programmed. It looks like linuxcnc is running smoothing and the way some of those lead out/in moves ate being trimmed to keep speed.
