[Sevy]

Howdy!

I've a big problem.
My spindle stops running automatically when the tool begin to machine the wood! and this message appears: Driver/Motor Fault! Location ??? ,
Just the spindle, the axes mouvement continue those actions.
What's the problem and the solution, please!

Any chance you have a real short bit in the spindle and you are at the bottom of its travel?
