Hey guys. We bought this setup a couple years ago and it's been sitting. The computer used to work but no longer, the one with a parallel port.
So I want to change over to a "stand alone external motion controller", or at least I think that's what I need.

Here is a pic of my full board. I have a power strip on the left, a power converter top center, and I believe a step motor controller

and a completely unlabeled wire bank top right, and a transformer bottom right.

I also have an emergency stop button.
My question is if I get something like this

that has a parallel port on the back like this

can I just plug it into the step motor controller that I have and leave everything else alone? Or is this machine going to conflict with the step motor controller?

Any suggestions on equipment would be greatly appreciated. I'd like something that I can load the G-code onto from a USB stick because I don't want to have to carry a computer to the shop from the house.
