The machine runs great and will accept any program that I put in it. The problem is when I spin the chuck by hand to get to the chuck key I get a spindle fault detected code. I opened the back and it's
flashing a 9 code. I've researched everything I could and can't figure out what I need to do next. I can shut the main power off and it will clear the code until the next time I have to turn the turn the chuck.

Thanks for any help,
