hey guys, im using the m31 probing macro that comes with the software, and the operation side of it works. it goes to the fixed probe location in X and Y, goes down and touches off twice at the desired rates, but it does not set tool length or set zero at the cnc bed or anywhere for that matter. if i home it, or zero it half of the z height, it remains the same no mater how many times i run the probing operation. thanks in advance!

The default M31 macro does a G44 H1 tool length offset.
If you want it to do something else, you'll need to modify the code.

maybe what i was using wasn't the original macro. i have used in the past, and am currently using the macro made by JOhn Revill version 1.16. it works great, but sets zero at the top of the work piece, rather than the cnc bed. his v 1.12 set it at the bottom of the cnc bed, but didn't have code to move to a fixed probe location. i've tried my best with my very limited understanding of c code to edit to change where it sets zero at, but have been unsuccessful thus far. its very frustrating as before my UCCNC program crashed and i had to reinstall it, everything worked exactly as i wanted it to, and i couldn't get UCCNC to recognize any of my other saved profiles, so i had to reset up everything from scratch.
