Arduino mini CNC plotter3

I rewrote it from the remix original, with the specifications extended by 40mm in length and width. If you don't have any parts, please download them from the original remix.

I didn't like the pen folder, so I put it together with a different design, with M3 screws to hold the pen in place.

I recommend this firmware because the Y axis is reversing the motor.
