CowTech Ciclop 3D Scanning Guide
alligator clip attached on the small screw of the Stepper Motor Driver. The multimeter should be
measuring a voltage somewhere between 0V and 1.2V
Twist the screw until the multimeter reads 0.48V. It’s ok to be a few hundredths of a volt off in
either direction.
Unplug the Uno Clone.
Stick the heat sink to the Stepper Motor Driver. The heat sink has an adhesive backing protected
by a layer of paper. Peel off the paper and stick the adhesive side of the heat sink to the black
square in the center of the Stepper Motor Driver (known as the IC). The heat sink ensures that
the driver does not overheat and burn out. Please make sure that the heat sink is not touching
any exposed metal surfaces on the driver such as the pins to the left and right of it.
Congratulations, you’re done with calibration!
