/**
* Spindle & Laser control
*
* Add the M3, M4, and M5 commands to turn the spindle/laser on and off, and
* to set spindle speed, spindle direction, and laser power.
*
* SuperPID is a router/spindle speed controller used in the CNC milling community.
* Marlin can be used to turn the spindle on and off. It can also be used to set
* the spindle speed from 5,000 to 30,000 RPM.
*
* You'll need to select a pin for the ON/OFF function and optionally choose a 0-5V
* hardware PWM pin for the speed control and a pin for the rotation direction.
*
* See https://marlinfw.org/docs/configuration/2.0.9/laser_spindle.html for more config details.

y la done a un colegio técnico salesiano. Hace años y moneda me salió hacer un desarrollo con una empresa que hace piscinas acá (un controlador gestor de piscinas programable) y como me pidieron 100 unidades compré algunas cosas, pero por los tiempos resolví con estos productores chinosqui... Cuando se me dió por seguir con el armado tuve el pre, el 2 pre, el infarto, los dos stent y en casa, ya el sueldo no era el mismo y decidí encajonarlo...Esa era más o menos la idea inicial, pero ya está, me confirmó con hacer ahora los PCB a mano y con la impresora hacer las cajas
