homemade gearbox from scanner/printer parts
Here is my new gearbox with stepper motors. Base of the gearbox is from two scanners/printer canon pixma mp150 (metal frame, motor and three gears), Last gear with output shaft is added by me. First setup was made with belt, but as I expected traction was not good. So at last version I come up with fourth gear on output shaft.
