I am now setting up my mach 3 software and there is something i am not clear about, on the motor output
tab on the ports and pins dialog
on the pmdx-122 i have 4 outputs 2 x 1y and 1 z
yet on the motor output tab it shows only 1 x setting to be enabled.
does this one setting supply both motors.
what would be the correct step and drive pins. what do i need to check to know if i am using the correct step and drive pins
this is on a shopbot cnc.
thanks paul

I dont know but are you running a gangtry style mill with 2 steppers or servos on the x axis? That is the only reason I would think there would be 2 X's in the output. I know in mach there is a setting for slaving an axis to any of the axis'. Are you running more than 1 parallel port? If no then the port should always be set to 1. Pins are dependent on your set up but I would think shopbots documentation would help with that. I dont know anything about a shopbot.

yes i have a gangtry style mill with 2 steppers on the x axis so then i need to slave the axis correct?
will have to do some more reading about how to get this done
thanks

You will need to set up the second motor on the X axis as an A then slave that with the X. There are settings on General Config page that you need to set as well, one that you must do is set the A as a linear axis rather than rotational and the other ones regarding the homing will depend on how your home switches are set up on the slaved axis.
