If you know g-code, even if you are only a little bit familiar you can open your .nc or .tap file with Note pad or a similar program , scroll all the way down to the last G00 line just before M30. The G-code line will be G0 Z 1. or what you set usually? Change this to G0 Z 2. press enter and then add X ___ Y___ to where you know that the torch will be setting over solid material. When you change the Z position make sure that there is clearance for the amount of Z lift that you want. SAVE your changes. If you are away from the machine when it finishes it will move to your preset location and then stop. Hope this helps.
