I have a 6 axis mill, all the axis are already taken up from the C23 board;)

Then you can build an amplifier circuit that would provide the same output current to both drives.

I'm just noticing this now.  The mill did sit for about 4 months but didn't do this before.  (I know, rediculous letting your mill sit that long).  I've just made a new control box.   Since the old mill wiring didn't reach the new box location, rewired the mill too, so I'm back to basically first time operation again.  Fun stuff, not.

You should be running a slaved axis.  Let Mach send step and dirextion signals to the A axis on the BOB and connect your A axis drive to the A axis on the BOB.  You already have the parts to do it.  You just need to rewire a little and set up the A axis in Mach.

What he's done should work just fine.  AFAIK, the only thing he's lost by NOT setting it up in Mach as a slaved axis is the ability to "zero" the slaved axis through the GUI.
