After cutting a part I went to cut another part and the torch would not move off it's highest point when told to run. X and Y moves are fine. The IHS error appears on the screen. The torch does move up and down manually and when I turn the laser off and on. I have warm booted and cold booted multiple times. I have removed the torch and replaced from magnet. Datum and reset z axis. The program just stalls with out the torch moving to maternal. Tried in dry and active run with the same issue.
