The 3A HobbyCNC motor works fine at 2.5A even with the torque reduction as it's overly powerful for the cross slide.
The more powerful Sanyo Denki motor is 2A. The Xylotex box can be quickly adjusted for motors less than 2.5A.
I really like the Xylotex box because it was reasonably priced, well documented, and is a "plug'n'play" unit.
But ... what CAM software are you using?
