Micro dummy CNC

Here is a little construction made for fun. When it comes to learning a program, what could be easier to put the little machine on the desk and watch and understand the movements. Mounted with an Arduino UNO, a shield for three motors and loaded with GRBL, one can imagine with a small milling cutter, machining compressed balsa. Free to place on it a PWM control module for the motor or other. During testing, the engine support parts made printed of PETG did not withstand the heat of the motors well because the phase current was set excessively. As a precaution, the three parts were made of loaded material resistant to high temperature.
