Printer to CNC: Update 2

I added the third stepper motor (which was a DC-Mootr before). Therefor I added a little shaft, which converts the 5mm shaft of the stepper motor to the about 1.5mm inner diameter of the gear which moves the belt

Then i added a pen to the Z-axis and a piece of wood to the X-axis (background of the picture), whrer the paper will lay on for the first test run.

I uploaded the test run on Youtube
