Small PCB CNC (Fully Printed Body)

Super cheap and completely printable mini CNC.

I had a few Parts left from an old 3D Printer which i wanted to use for a tiny CNC which i can use to mill (engrave) PCB´s and smaller parts for my micro RC Trucks.

For the Ramps I´m using a modified version of the RS-CNC Marlin code (i will upload it during the week) I connected the Spindle motor to the FAN output and modified my Start and End gcode with M106 (on) at the beginning and M107 (off) at the end.

I will also Upload a few more videos and files.
