I have been up and running since my ordeal with my Monport 80W laser. Now I hit a snag I have never had in the year I have been running. I can’t clear the previous job. I have been hitting ESC. I shut off machine several times. Even unplugged. But keeps wanting to execute the last job which was just a simple line cut. Have also pushed the red RESET button and still stuck. How to I clear the controller to accept a new job?
