Q.) How hot is too hot for a step motor?
A.) The maximum heat for most steppers is around 100ºC (212ºF), but it is generally never good
to have the motor heat go above 85ºC (185ºF).
Q.) How should I heatsink my drive?
There is not drive-specific heatsink for any Geckodrive, and there are a variety of ways to
heatsink your drive. What you should do is ensure that your heatsink has fins to increase surface
area, and have air flowing over it. A good heatsink to use is a standard CPU heatsink with some
heatsink compound in between the drive’s plate and the finned aluminum heatsink. The method
to determining if it is being cooled adequately is to feel the drive while it is running. If it is
uncomfortable to the touch, then the electronics are uncomfortable as well.
