i am useing mach3 mill. when i do M6 T2 program stop and waiting for cycle start. it is ok but when i press cykle start spindle dont start. what is wrong?
sorry my bad english

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.

Hi,

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)
