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?
