Hello all, relatively new to Mach 3 - when I first power the machine on and start the software up, I set X, Y, and Z settings before running a gcode. When I hit cycle start, the tool moves WAY up above the z I had set and does its thing in mid air. X and Y stay put where I set them but Z goes up a few inches. This only happens when I first use the machine in the morning. It happens every time; I just hit the spacebar, reset the Z and reload the gcode and it runs as it's supposed to. What am I doing wrong here? RTFM I know, but the manual for Mach 3 puts me to sleep and doesn't really answer my queries in a language that I can get my head around. Aside from minor issues I've been having I'm starting to get better with it. thanks
