Gee, that doesn't sound so good. After 2 hours or so, that might be
acceptable, but if it gets that hot in 10 - 15 minutes, they will burn
up. You may have to reduce the voltage, or the current.

Is it the MOTORS that are slow, or the computer? Did it lose steps
and start rattling if you got above a certain speed, or did it run smoothly,
just not fast enough? If the latter, that just means your computer and
software can't go fast enough. Speed that up, or set the Gecko 210
to multiply the steps by some factor (reduce microstepping).

You must be using EMC and freqmod.o, which simulates a servo
in software. Apply a little DEADBAND in the .ini file for axis_2,
something like 0.001 to stop the hunting.

It depends on the machine, motors, need for speed, software, etc.
Generally, you want it as high as possible, until it cuts into performance.
