I just bought the SparkFun stepper motor 1568-1105-ND and the BigEasy driver 1568-1066-ND and hooked them up (see attached photos) to an Arduino Uno with a 24v 5A power supply for the motor and USB power for the UNO following the Big Easy Driver User Manual v1.2 (the board is v1.6a) instructions. I set the trimpot Vref to .29v (motor spec is .33A per coil) and ran the script supplied in the manual . All LEDs indicated power but no movement.
I then attempted to use the BigEasy Hookup Guide’s method of adjusting the trimpot by starting at OFF and slowly turning it up until you get movement from the motor. No movement. The motor heated up to approx 49C and the BigEasy board heated up mildly.
What am I missing here?
