My steppers seem to be getting very hot. They get hot enough where I cant keep my hand on them. Here are the specs i'm using:
Power Supply: 63V @ 15 Amps
Stepper(s): 3.1V @ 5 Amps X 3
Drives: Gecko 203V X 3
I'm using a 120K current resistor as suggested. Should I incease the resistor size and if so how much??
