Do I need to turn it off in the M6 script?
If so, how do I make sure it is stopped before it tries to release the tool and make the change?
I do not have a spindle encoder. It runs off a VFD connected to 0-10V output and CW CCW relays from the BOB.
I do not see anything in my Mach3 M6 script that did this, and I don't recall what happens or how it knew not to start the change without the spindle stopping first. I can only guess I somehow it knew to turn off the spindle and then wait a certain amount of time that would allow it to stop from it's highest RPM....it has been too long.
