Hood, Glad to see you're on at the moment.

I'm back at is again and now i have something odd going on. The spindle won't come on at S500, but does at S800 command and when it does it starts abruptly and runs at ~4000 rpm. No matter what I change the pot on the C11 to, it still sounds like its about to strip the gears when starting and while running.

To recap yesterday, all I did was play with the motor tuning and turn the pot.  I've see the steps per back to 1000 but can't get the accelleration down below 6.25. It starts off like a bat out of Hades.

Wonder now what miight be going on.  Like I said, I contact Arturo tomorrow. Just wondering if I might have missed something being set back to its original state before all this began.
