Easy To Build Stepper Controller from Recycled Materials

Step 2 Get Parts from Old Scanner

The first step to building your cnc controller is to extract your motor and control board. I did not take any pictures of this step because every scanner is different, but it is usually as simple as removing the glass and taking out a few screws. The two parts you are looking for are the stepper motor and the control board, but also keep the nice metal rods so that you can use them to test you motor.
