I am a new Mach3 user trying to figure out how to make this program work.  I've got my X-Y axis working on my router.  I can turn the spindle on and off.  I am running into a problem though, with the Z axis.  The Z on this new router is an air cylinder so it is either on or off, but my G-code is coming from being run on a 3 axis CNC (G0 Z.060).  How can I get Z to "turn on" when Z plunges and "turn off" when it retracts.  All Z Values in the code are either .060 deep or 0 (Reason why I can fix Z depth on this new router).  Any thoughts would be appreciated!  Roger
