Documentation Update Coming Soon
Some descriptions on our product pages and Wiki may still state that grblHAL support is under development. We are updating these pages and will publish the revised instructions as soon as possible.
The board is currently marked Experimental in the Web Builder. We recommend backing up your existing settings and carefully verifying your configuration before using the firmware on a production machine.
