First Proper CNC Router

[diycnc]

So after almost a year, the mechanical part of this build is still progressing .... very slowly!

For the electronics, I have just got 3 DM860T drivers from stepper online to power my 3.1Nm Nema 23's.
I would quite like to wire up the motors just to check everything is working correctly, so starting to think more about BOB and PSU.
The drivers can take either AC of DC input.
I like the idea of AC as it make the power supply build a little simpler, but is there any downside to using an AC input?
Any advice for BOB? I plan on using linuxCNC.

Thanks,

If you have a spare arduino lying around and a PSU that can run 1 motor temporarily, you can test them reasonably easily just to check everything is okay.
