I just did that… and didn’t work.

What did work is when I clicked ‘Tool touch off’

Can you post the first 20 or 30 lines of the G-code?

I’m sorry I does work…
I only changed the Z-limit max of the joint and not the axis.
Now I changed both and it works!

Thanks for the help!

For some reason I could open the tool table now… here I see it doesn’t match with my Fusion library. Should I sync it and if yes, is there an easy way to do this?

I thought that I answered this.

Fusion has an option to use tool diameter compensation in the CAM or in the controller.

But the tool length is just assumed to be correct, ie Fusion assumes that after a G43 the tool point is at the controlled point.

The tool length data in Fusion is only for the graphics. The tool length data in LinuxCNC is the important one. (and should be set by touch-off or tool-probe, not from measuring the tool)

I don't want this to be a thread hijack, but I'm a newbie and also struggling with Z limits. What's the convention for Z limits, 0 (table) to 100 (fully up) or -100 for table and 0 for fully up?

Usually for mills it is 0 up and -100 down to the table, then use G54 offset to set 0 at the top of the workpiece.
