You obviously Don't control spindle thru software with your other 2 Cnc machines then.? . . . To reverse spindle direction thru software use M4 G-code command, M3 is Clockwise M4 Anti Clockwise M5 spindle Stop.
When you get your V4 spindle board you'll need to set Mach3 up in (ports&pins/spindle Setup) for turning ON/OFF Output for Direction in relation to each Commnand. Ie M3= Output #1
You'll Also have to set up the Output # to a Output pin on your BOB. This is done in (ports&pins/Output signals). Often this is relay on the BOB which is assigned an Output Pin.Last edited by JAZZCNC; 24-02-2015 at 09:06 PM.
