I inherited a Dental Mill and I have it working with EMC2, but
I'm having some small problems with the spindle motor.
Sometime it doesn't want to start. It turns about 120-degrees
over and over but doesn't spin up. Sometimes it spins up fine.
I can always get it started by toggling the spindle on/

So it looks like the relay switches between two possible spindle
