  • Additional Information:

    Unit is driving a Mercury Stepper also purchased from SF, and the power to it is from the Arduino's 5v regulated output port. If I use the Vin port (12v), the stepper and the driver become very hot. I am using the Accelstepper.h library, and have the speed and acceleration set at 400 max, and 250 accel.

  • I am using the ED with an Arduino Mega to automate a device that depends on precise positioning. However, when I use a 12v 5amp power supply in the Arduino, everything works find. When I replace the power supply with a 12v 2 amp unit, the stepper creeps a bit before the initialization is complete, but enough to screw up the positioning. Any ideas?

No public wish lists :(
