You do not say how you have wired yur three axis. I assume you have used stepper motor. Each stepper motor has a drive card which require a "step" wire, a "dir" wire and an earth wire.
I assumw you are using an LPT1 parrallel port output to your machine.
The outputs to the machine can be pins 2 to 9 and 1,14,16 and 17.
It is normal, but not essential, that you put X on 2,3 Y on 4,5 and Z on 6,7. 8,9 are normally kept for an A axis but can be used for other things. 1,14,16 and 17 are used for output to the spindle, etc.
These are allocated on Config/Ports and Pins/ Motor Outputs.
Make sure you motor drivers are wire to seperate pins, and also the allocation is properly done on Ports and Pins.
