Stepper motors getting HOT!

Thanks Mark!

So I actually am driving the motors with 24V.

I guess my issue comes down to two questions:

Should I be seeing current in excess of the current limit I set, when reading the current on an individual lead to the motor? I didn't think so, but if I'm misunderstanding something here - could you please explain?

And regardless of the answer to that - why do the motors still get hot even after I set the limit so low that I can no longer move the motors?

My goal is to not heat the motors any hotter than the original comtroller. If it can move them without getting hot - why can't I?

And I don't have an option to modify the mounting. So how hot should I let them get without worrying? When I set the current limit according to the ratings on the motors, they get hot enough that I start smelling something burning.
