Mini Plotter cnc

I had a few cd, dvd engines and I decided to make a cnc mini plotter, I saw that it was something that used to be done to get some practice with arduino, grbl, universal gcode sender.
The design is adapted to the motors and gears that I had, although any modification will not be complex.
The movement tests have been satisfactory. A little bit of glue is necessary to stick gears to printed pieces.
