I got my spindle to turn on via Mach 3, but when it is on Mach 3 thinks it is off and vice versa.

No speed control, seems to be at full speed.

Any ideas?

Thanx, Alan

Finally found some instruction for my BOB and got it set up per them.
Now as soon as the BOB receives 5v from the computer, the spindle starts.
I can do spindle calibration as long as Mach 3 agrees that the spindle is running, by tapping start/stop until it recognizes start.
The spindle is continuing to run the whole time. 

This was a temporary spindle until I could afford something better, so I guess I will just manually control it, which works fine.
The only thing I don't like about that is that the pot that came with it only has about a quarter turn throw, so it may be difficult to get exactly the right speed.
