Last night I was running a program doing a pocket, everything was zero’d in just fine and had started cutting. I got interrupted and needed to leave the machine. I paused it, then stopped the program rather than leave it running. When I came back I started running the project from the beginning, expecting it to cut air until it got to where I had paused/stopped the previous run. Instead, it started cutting twice as deep as it should have. Stopped the machine and re-zeroed and my zero was about 4.7mm lower than it should have been. Since I was cutting a 0.1855 (4.7mm) deep pocket, seems like it picked up the bottom of the cut as the zero. The XXL and laptop had stayed powered on with CM still running.
Should I check the zero every time i stop a run, or was that just a one time weirdness?
