I have a setup with two steppers attached onto a 24V/10amp supply. I need to get a lot of torque out of both motors, but what is weird is that I can adjust the potentiometer for the current for one motor and get it running really smooth, but when I play with the potentiometer on the second motor, the first motors starts to go goofy. Thoughts?

More decoupling required?  Are you running the cables for the motors close to any other cabling?  I presume
10A is more than enough.

I had split the power supply wire into two sets of power/ground wires for the two BES. These wires were 22 gauge (I just pulled some wires off of a breadboard in haste). I put some larger wires in and it seems to have fixed the issue. Thanks for your ideas, though.
