I read here ( https://groups.google.com/forum/#!to...ot/gN_W4GieQwk ) that it's possible the stepper motors are running on too high a current. Is that possibly my issue? (As a reminder, the firmware I'm running is Sailfish ver 7.1)
What are you current settings on the digpots? You can read them out via the Rep-G sailfish program.

I have several Qidi's and a Flashforge (all running sailfish 7.x), and none of those get hot steppers during printing.

Can you find any serial number/product number on the steppers and look up the advised currents?
