grblHAL for Arduino DUE

grabcad

This is a grblHAL controller that uses the Tinyg2 pinout. It's an upgrade from my Tinyg controller in that it can use the spindle PWM line for a laser engraver/cutter module.This is designed for use with dual motor Y axis gantry systems.As with the previous incarnation, the motor interface is via a 2x2 RJ45 interface. The other connectors are JST compatible 2 and 3 pin headers.If interested, I could build a limited number of these for sale. Cost depends on the level of interest.
