I wired up the motors and tested mach3.
Some things changed in the pins settings, the motors for X Y and Z all got populated with pulse and dir pins, but not A.
I tried running the motors and they all worked fine, except I have not been able to get the A motor to turn.
I swapped the wiring over between X and A and the motor and driver is fine, so the settings for A are not there in the configuration.
I tried putting in some settings from another setup that has 5 axis, and it didn't work, so now I don't know what to try next as far as getting A to work with Y as a slave. (or even separately just to test it)

dazp1976 I have both a 32 bit machine and a 64 bit machine, the board is working fine on either one. I have already ordered and waiting on a 4 channel relay board to come.
I have several Mach3 boards, all different from each other, some have almost no outputs except for a single relay. I have an old Dell computer that runs XP and also has a parallel port that I might end up using.
