Using an arduino and gshield to run some bigger drivers and motors: ie nema 34

I normally run Linuxcnc and a Gecko G540 controller with my X-Carve. I wanted to give Easel a try so made up this device.
Running the X-Carve via grbl with a Gecko G540 controller

It’s based on a cncshield, mostly because I had one on hand. It does work although I must admit I haven’t fully finished it as yet - still have home/limit switch configurations to sort out, plus I’ve been busy just using the X-Carve in it’s normal configuration.
So it’s doable as long as you’re able to work out the required control signals.
