Universal Laser Controller GRBL
thingiverse
The Box houses a custom-built PWM PCB alongside an Arduino equipped with a GRBL shield. The PWM PCB is designed to operate in multiple modes: - It receives ENABLE and PWM signals from the GRBL shield. - It enables itself via the GRBL while generating its own PWM signal. - The PWM signal is constantly high, with the PCB generating it on its own. - External ENABLE signals are used alongside a self-generated PWM output. - External ENABLE signals control the operation, with a separate PWM signal also being generated. Further code and instructions can be provided upon request. Printing occurs at 0.2mm layer height using PLA material. Supports are unnecessary for this process.
