I have an Arclight 4x8 table with a Hypertherm 65 plasma and machine torch running Mach3. The torch will dive into the metal almost as soon as it starts the move, rapid or travel. I’ve been on with tech support several times over the past many months but have not resolved the issue. The Z axis switch is working OK. The tool set has been replaced as it was found to be corrupt. Numerous settings were checked and verified. Strange thing is that from time to time it will work as intended for a short time. I’m at a loss as to where to go next. Has anyone seen this?
