I have a strange notion that they get hotter as the load increases. I could be wrong but I seem to remember mine get hot when I put in a fat ripper and cut uphill through steel. Usually I'm an 8mm dowhill in aluminium sort bloke and my motors run lukewarm.

You'd think it would be the same regardless of loading but I'm starting to wonder if stepper motors might be a black art :naughty:

Whatever, I have the motors, I have the drives, I have fat wires and trunking. If the shrinkwrap arrives tomorrow I will wire them up over the weekend then report back
