I have a UC100 coupled to a 3 axis Sherline mill.
The Z axis step and direction output from the UC100 has recently failed. X & Y axis working ok.
(It would appear that the processor in the UC100 is not user replaceable and a new UC100 is around £150!)
I can go into Ports & Pins to enable the A axis and setting Step and Direction pins to 8 & 9. However . . . . . . . . .
Is there a way of fooling Mach3 to output Z axis step and direction info to the currently unused the A axis?
