I recently implemented a Z-zero plate on my SO2 CNC. I'm using the Macro page in UGS to hold the commands. My first macro is G20 G38.2 Z-0.5 F2; G92 Z0.5. For simplicity, I'd like to add another command to raise Z another .25" while leaving the reference point at 0.5", the thickness of my plate. So far, whatever I do causes an error, unless I unplug the Z-zero plate. Ideally, I'd like to add to the one macro; i.e., G20 G38.2 Z-.5 F2; G92 Z0.5; ______ Z0.75. Is this possible?
