Arduino mini CNC plotter4

The original design makes it difficult to get support when the rails are printed. I converted it to a trapezoidal rail.

1.stl ~ 4.stl Updated.

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.

Here's the part of the movement that reverses the movement of the Y-axis.　https://www.thingiverse.com/thing:4637293

I recommend this firmware because the Y axis is reversing the motor. https://github.com/imaicom/GRBL-28byj-48/
