cnc shield burns ( literally)

Post by mad Unfocused » Wed May 13, 2020 5:13 pm

I bought a cnc shield some time ago to replace the brain of an XYZ Leonardo jr 3d printer because the Leonardo jr was so locked down it was rediculous. I got it all hooked up to the three axies and it ran great for about fifteen seconds at which point part of the board lit up (fire). I got a replacement and the same area started to get hot.
What information do y'all need to help me figure out how to make this work?

I jumpered past the burnout and it works... Except the wire gets really hot.

I would suggest you get the latest version : ... ivers.html

It can run the latest GRBL version.

V3 - This was the build guide for that version... ... bly-guide/
