I didn’t want it to come to this! After many attempts to get the printer to go forward on its own accord (many resulting in ruining the control board and having to buy a new printer) i have brought out the secret weapon – ARDUINO.  I also bought a heavily geared down DC motor from Tamiya. These factors combined result in some serious direct to everything progress!

The video shows the printer stepping forwards at a pace set by the Resistance registered by a potentiometer. Later on the potentiometer will be very important in tweaking the printer so it outputs correctly. The DC motor has more than enough power to move the printer.

Circuit:

The black and red wires go directly to the dc motor. The power is switched using a simple transistor.
