Tom
That auto Z touchoff file you helped me with works fine, but
at the end it sets Z to zero in machine coordinates

I would like it to set to Z zero in G54[or any active offset]
and not overwrite the G53/machine position.

Is that doable?
thanks
Carl

How about the G92 offset? (Like the Zero button next to the Z DRO). That will not affect the G53 machine coordinates.

Yes
that is what I told my customer to do, but of course that's
"one more click"
you probably wouldn't be surprised that I get asked things like
"why doesn't the machine know how thick my material is "??
isn't there an app for that??

Hi Carl,

Well, I asked because it is easier to do a SetZero from KFLOP than to change the Fixture offsets and re-apply them (I asked to see if that was acceptable functionality not to tell him/her to push the button).

You can add this function call to your probe program:

DoPCFloat(PC_COMM_SET_Z,0.0);

But you need to add two helper functions into your program called:

int DoPC(int cmd);
int DoPCFloat(int cmd, float f);

These compiler definitions need to be added before your main function and the "bodies" of these functions need to be added as well (anywhere except inside your main function - at the end of your file is best)

See the example C Programs\KFLOPtoPCCmdExamples.c
