After a time with a multimeter and scope, the othewise-undocumented Cronos board for home-build cnc machines has revealed some of its secrets. Overall, it seems like a proper grown-up design with a ...

There’s extensive documentation, GRBL settings, and more pictures in their GitHub repo, too – in case you have a similar CNC and would like to learn about upgrading its controller board!

Components used to build the DIY Arduino CNC machine project include an Arduino Uno development board, CNC stepper shield running GRBL for control, together with NEMA 17 steppers and motor drivers ...

In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to analogue converter is needed. The machine uses a ‘grbl’ controller, which has an ...

Being only ten at the time I was unable to build the thing and, now that I’m 40, I still can’t fathom how to build this DIY CNC plotter out of a DVD player and some Arduino gear.
