A tool change normally does not restart the spindle. It is normally restarted via Gcode after the machine clears the tool change area .

YOU can alter the M6end macro to auto restart the spindle .

To the M6end add  DoSpinCW() to the end of the file.  Just remember it willl autostart the spindle EVEN if it is not where you want it to be(;-)

Hope that helps, (;-) TP

Yes, be careful with having the toolchange macro start the spindle.

I was doing that with my auto zero macro (as part of M6) UNTIL the spindle started unexpectedly.

At that point, I decided to let the g-code start the spindle.

Safer to write in your Gcode:-

T2 M06         (Tool change to tool 2)
G43 H2       (apply tool lenght offset if you have programmed the tool table)
M03 S1000 (turn spindle on and set speed)

You can "chop it off" but can't "chop it on"
