Click the “Open” button at the top left of the window, select the file you want to open, and click “Open”. Then click the “RUN” button under the code listing! A G-code program made with our SheetCam post for plasma cutting will have an M0 (pause) after setting some initial settings for the DTHC. This pause is to allow you to check the settings and make sure they are correct. So after clicking “RUN”, the button will light up briefly, and then the button underneath it will light up yellow and say “Resume”. Click that button to continue running the program.
