I have recently been offered 2 small DIY CNC devices that are orphaned and have zero support or documentation. My hunch is they are built on the order of a Bob’s CNC (Bobscnc.com) which is designed to use GRBL1.1 firmware on the Arduino Uno.
Totally outside of my knowledge and experience, but am hoping someone can guide me enough to figure out how to get at least one of them running so I can give it to my woodworking enthusiast 9 yo grandson.
Open to any suggestions on how to proceed.
