CSMIO/IP-M vs Ethernet SmoothStepper (Begone foul parallel port!)

[EddyCurrent]

Right this is how I have it set up.
ESS, Mach3, 4 inputs for home limits X Y Z A, I have A slaved off X because I'm using 2 ballscrews with one stepper motor each. I used the settings in Mach3 to slave A from X.
I pressed the 'Ref All Home' button on Mach3 screen and the Z axis moved first, hit the home limit, reversed slightly then stopped and moved onto the Y limit with same result. It then moved both X and A motors until one of them hit it's own home limit, reversed slightly then ran the other motor until it also hit it's home limit and stopped.
I tried it both ways round i.e. letting it hit A limit before X and X before A and it worked perfectly both times.

The reason I used 4 inputs for the home limits is because having worked with PLC's for many years that is the method of choice, anyway I rewired X Y Z in series so they used the same input while A used another input. It worked fine just as previous and it didn't mind if the A limit operated before the X or vice versa.

My conclusion is, there is no problem with the Smooth Stepper and Mach3 with regards to slaved motors using two home limits (one per motor) provided at least one of the slaved axis home limits has it's own input.
