Title: Z axis on/off
Post by: quilt-ez on May 26, 2006, 03:15:14 PM

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

This can be done a few ways.. We could have the Macropump look at the Zvalue and IF it is Negitive will push the Zdown and if it is positive it will pick it up.


Is that what you are looking for?

Put code in the MacroPump.m1s like this:

if(GetDRO(2 < 0.0 ) Then
   ActivateSignal(Output1)
else
  Deactivatesignal(Output1)
end if

There is a Wiki on the support page telling how to do a Macro pump under the Modio.. Hope that helps
