I've got 4 gecko 203V's driving 4 hobby cnc 425 oz/in steppers. I am using a 56V DC power supply. The steppers get quite warm with the controller on and the steppers not moving. I just ran a program that cut for about 30 minutes and the steppers were hot. I couldn't hold my hand on them for more than 2 seconds. Is this normal? Is there something I can tweak in mach 3 to allow the geckos to drive them cooler?
thanks,
Brendin
