From the time i insert card and turn on machine the cut motor keeps intermittently trying to start (like just 1 second pulse not fully starting ). It does this all the way through setup until i start project. It does not do it when bit is touching off or as it find board thickness or surface but it is doing it right before and after. Also it carves the projects just fine but when project is done and it shows time it took. Motor continues to cut on and off till i turn it off. Was reading a couple of post about the triad and pulses getting through to the x termination board was also told maybe main board. Has anyone had experience like this or any ideas? THANKS
