    Exclamation Pin assignments - software

    Hello all,
    I have setup my first 2 axes stepper mill (hardware only) with ULN2003 chips and uni-polar motors.
    I need a program recommendation and a little help with pin assignments.

    For x axis (stepper motor A)- I use 4 pins on the parallel port (2,3,4 & 5)
    For y axis (stepper motor b)- I use 4 more pins (6,7,8 & 9)
    I would like to have pin 10 control the laser turning on/off

    I have played around a little with Mach3, but i dont understand how to properly assign the pins.
    can someone please help?
    Im all ears to recommendations on easier software to use for laser engraving.

    Any help is greatly appreciated!

    Click on ports and pins to the left...a great video on configuring any setting and a excellant support forum for this software.
