New 2.5D pen/laser ESP32 controller

20181128_204306

Bdring published a new build:

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.

Project info at Buildlog.Net blog and the library GitHub repository here. It’s also up on Tindie.
