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!

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 ...

To controller this CNC machine we need a microcontroller board called arduino Nano and we need motor driver IC for each stepper motor that is L293D IC.
