Plcm-e4

[JAZZCNC]

it came with this, im guessing i connect the steppers driver through the virtual lpt then

That's just a DB25 terminal block. You really need a proper breakout board that offers some signal isolation to protect the controller. The breakout board will also provide a few other features like Spindle speed controller and relay.

It's been a while since I used the PLCM-e4 so I've forgotten exactly what it provides regards input/outputs etc but think i'm correct in saying to get full use you'll need either dedicated board that offers enough I/O to make full use or will need 2 or more standard breakout boards.

I'll see if can find the manual to refresh my memory.!
