Alright, chopping up a cable is do-able.
Is there a setting in Mach 3 that I can use to give a constant 5v signal on pin 14?

Alright, so I have found the pinouts for what I believe to be all the flashcut boxes.
I attached the pins as an image, but here is the pins written out in case that does not work.

Pin 9   X direction
Pin 10  A step
Pin 11 Z step
Pin 12 Y step
Pin 13 X step
Pin 14 Enable All

Pin 19  A direction
Pin 20 Z direction
Pin 21 Y direction
Pin 22 Internal VCC +5V (connected to 23)
Pin 23 OPT VCC  (Input) (connected to 22)
Pin 24 Internal GND  (connected to 25)
Pin 25 OPT GND  (connected to 24)

So although I have the correct step and direction pins set in mach 3, the steppers are not moving.
I am guess that this has to do with pin 14, Enable all. Is there any way to set mach 3 to give an "enable All' command? I would assume it would be a +5V signal, rather than an active low.

Hello, I am very new to CNC machining and I am trying to get a mill with a flashcut CNC conversion to work under mach 3, as the flashcut box does not support the new live version of the flashcut software. So far I have been unable to make the machine jog using Mach 3. I read somewhere that there is a trick or two that is needed to  get mach3 to run on the flashcut box.
So far I have set up the ports an pins in exactly the same manner as the tutorial, although I believe that since the flashcut box is proprietary they do not use the basic pin 1 step y pin 2 dir y setup.

My setup for running mach3 is an LPT cable (not a crossover) directly connected to the flashcut box that runs the motors, and so far I haven't gotten any stepper motors to move.
