DIY CNC router | Arduino + GRBL + NEMA23

In this post I have build a heavy duty CNC router using arduino GRBL and nema 23 stepper motors.

I also have designed a custom made PCB to make possible to run NEMA23 with GRBL.

Machine dimension

over all dimension = 750 x 550 x 650 mm

Work area dimension = 330 x 330 x 50 mm
