I added a post last week and still haven't hear anything back yet, so I'm going to try one more time. I really need your help with this one. I"m slaving my A axis with the Y Axis using Mach3. When I rereference homing on all Axis the Z axis home first an the A & Y together, then the X Axis is the last one to home, But afterwards the A Axis tries to rehome again. I think I"ve I got one of the setting set wrong in the program but I'm not sure. I'm out of ideals so I hope you can help me.
