DIY Pen/Laser Engraver ESP32 Controller

Buildlog.Net Blog published a new project. It’s an ESP32 Controller board used to control X/Y and Z axis of Pen or Laser engraving machines.

I have done several pen and laser machines lately, so I decided to create a custom PCB for Grbl_ESP32 for these types of machines. This is a small (70mm x 60mm) PCB with all the features a pen plotter or laser cutter/engraver would need.

These typically use stepper motors for the X and Y axes. On pen plotters, the Z axis is controlled by a servo or solenoid. On lasers you need an accurate PWM for laser power control.
