Michael;
Warm is OK. Hot to hold may be a bit much.
I'm not familiar with your controller but many stepper drivers have the
ability to reduce the idle (not stepping) current to the motors, if you
don't
need the high holding idle current for your application.
I have been known to circulate air over the motors when I needed the high
current. A fan moving a little air over the motors will usually do.
Good luck
Don

The ultimate all-in-one performance toolkit: Intel(R) Parallel Studio XE:
Pinpoint memory and threading errors before they happen.
Find and fix more than 250 security defects in the development cycle.
Locate bottlenecks in serial and parallel code that limit performance.
