I think that this might be the bug here:
github.com/LinuxCNC/linuxcnc/issues/559

Make sure that O<manual_change> isn't % delimited.

Is it the line FEATURES = 30 that is the culprit?

Obviously I have missed to copy axcisrc to my home directory.

So I will copy the file and see the outcome.

I have som minor issues with probing the tool length.

Z axis kind of overshoots a bit and the probing cycle is too fast so following error is there.


Can I get som help here how to make this change from first trip of probe to let Z axis return a bit before trigger is on for the return.
I assume that some changes in manual_change.ngc has to be done.

Did you check the state of motion.probe_input in the HALmeter or HALshow
mashine Menue
when MDI triggering the NGC

No, just physical observation that probe was still triggered when G38.x went active. Only way out of this triggered position was to jog with MPG in + direction.

I can run probe_down.ngc without any problems. Will have to compare gcode and see if I can find a way to solve this behavior.
