I have a 770 pcnc, it has been used very little. I turned on the spindle today and it changed directions all by it self. Nothing I do will reverse directions. Not even the manual control panel will reverse it. Anyone else encounter this??????????

Not sure if this helps..... I have a PC1100 that developed a similar issue after a near by lighting strike several years back. It took out the interface control board.

Have you checked cables and terminal connections?

Thanks for the response! I'm pretty sure the cables are ok. Also, I have since discovered, it will suddenly change directions indiscriminately. Also I am still using Mach3.
