not sure youll get 1500mm/min pushing that back n forth
im guessing you will have to use belts and pullies to up the torque

Out of those motors I'd go for the last one, with the biggest torque. Except your driver is only 2.5A...I think that's near enough though. Definitely get a 4 (or 8) lead motor. Your milling machine is very similar to mine and I found that when I started with 1nm motors they just didn't have enough torque to go above a few mm/s and required pulley reduction, so I upgraded to 3nm motors from Zapp, with their 70v drivers which works very well.

By all means try using the driver you've got, it'll work and if you don't mind it being a bit slow that's fine. I do advise getting quite big nema23 motors though. They'll serve you well if you get a better driver.
