Path in Fusion360 different from actual path

Hi,

I have the issue, that on moves between cuts, the CNC starts moving in X/Y before Z is fully lifted out of the hole. That very often kills the cutter. In Fusion360 those linking moves are shown as perfectly rectangular moves. The Previewer in LinuxCNC shows the linking moves with an arc at the top, where Fusion360 shows a sharp corner.

Does anybody know why this is, and how to prevent this issue?

Thanks,
Max

Maybe a path blending issue?

That was discussed here on the forum lately but i can not find the topic, not sure what happened later but you might want to try to update LinuxCNC.

I had something similar once while engraving. Sharp corners were rounded off because by default the G64 command was active. That also occurred during lifting of the tool.

It looks like G64 could be the issue. How can I disable that? Nowhere in my GCode I can find a G64. Is it somewhere in the machine configurations?

It's enabled by default. Have a look at the docs I linked above, it shows how to disable it are maybe better to adjust the tolerance to a small number. It's just a gcode command, you can add it to your pp.
