Arduino mini CNC plotter2

One aluminum 10 mm square pipe was used. The square pipe is excellent for distance in a straight line. The redesign was simply a hobby. A number of M3 screws are required for assembly.

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.

This is an optional part that converts to a trapezoidal rail.
