I  am having trouble slaving the x-axis to the a-axis.  Went to config/slave axis/x-axis and checked the slaved a-axis slot.  restarted the program and it will not slave.  in fact i tried every combination and nothing (Slaved x to a, y to a z to a).  I did notice that the Zero4 - DRO does not move when the axis was programed to slave .  when i do not slave the a-axis the dRO moves and so does the motor.  So the motor and driver are good.  Yes i have one of those chinese XHC-MK6 motion controllers that stipulate that it is Mach 3 capatiable.  Any suggestions, does anyone know where i can get support from the XHC-Mk6 motion controller? 

 Hi Big Bop,

  Its been awhile sense you posted, but I will try. Have you enabled the A axis port under ports and pins?

Check General Config and see that the A is defined in agreemnet with what your trying. IE; linear or angular

Can't be of any help on the Chinee stuff though,

Yes i have one of those chinese XHC-MK6 motion controllers that stipulate that it is Mach 3 compatible.

When the a axis is slaved to another axis, the 4th axis DRO will NOT show movement, but the motor should move.

Are there any slaving options in the plugin configuration?
You might check with the manufacturer to see if they support slaving.
