Help ID this stepper motor?

[Mike vonBuelow]

Any way to tell what motor this is? I didn't see any markings

It's mounted on my Lumenlab CNC, trying to figure out how to connect it to my driver board

Mike...
Is that a 4 wire motor? IF so, its fairly easy. Ohm out the pairs, or use a continuity tester, to see which wires are for each coil. Each coil (wire pair with continuity)will wire to A+ & A-, or B+ & B-. If the motor turns in the wrong direction, reverse the wires to one coil.

You can determine which wires are paired by connecting two and then trying to turn the shaft, but it's easier just to wire it up, and swap pairs until it works.
