Stepper motors too hot!

Err as in, have a 6v Rail and a 3v rail

Turn down the pots on the A4988 boards to reduce the current going to the motors

I know this is an old thread but the new hybrid stepper motors are really good. They vary the draw depending on load, and run much cooler.

Motors or the drivers? I know the new trinamic chip replacements for the A4988 chips are WAY better. Especially if you use the upgraded driver software.

Yup those trinamic drivers are really neat.
