ok found your post ................

The one opposite the Nano is the X, the other is for the 2 Y motor's.

Vref / 0.8 = Imax, so the X motor is current limited at 0.5A and it runs smooth with no excessive heat buildup. It could go higher but there's no point.

The Y motors are limited to less current each but with 2 of them to share the load everything works well.

That is mounted upside down compared to our machines. So your X is lower left. The next two to the right are your Y.

I'm pretty sure benbox comes with the firmware, it's usually called LX??.hex and can be uploaded from their program.
