Stepper turning in only ONE direction

Im converting (yet another) LMS mini mill to CNC. Trying to, at least. Im very new to this and having trouble finding a diagram on how to wire these digital drivers to the BOB. Im not sure why, but I thought I just be able to look it up and move forward. This hasnt been the case, and im worried I might screw something up and fry a driver/motor or something. Any help from you gurus would be much appreciated!

This is the kit I have:

eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices

I came across this, but it didnt help:
CNC breakout board: DB-25 and DB-9 pin assignment

Here's where I am now. The power supply is 48V.

In Mach 3 I currently have:
Step Pin set at p2
Dir Pin set at p3

P2 to PUL-(PUL)
P3 to DIR-(DIR)

And 5V+ connected to PUL+ (+5V)
DIR+(+5V)
ENBL+(+5V)

I also have both "LowActive" buttons clicked on this axis.

The motor still turns very slowly in one direction. Any help would be much appreciated.
