I f using a GRBL-AIO board and are using an external programmer, REMOVE JP1 from your GRBLAIO before programming and put it back afterwards!

Select the ‘Clone or download’ drop down box and click ‘Download ZIP’ to begin download.Browse to the latest GRBL Release on Git-Hub here.It may prompt you to install several drivers, just say yes. Current version at the time of this post is 1.8.5.Ĭhoose and download the file for the appropriate operating system download, note for windows you should select the windows installer, not the non-admin install (as it won’t install the useful drivers for you).ĭouble click on the installer file you have downloaded and follow the prompts to install the Arduino interface. It is also a simple way to compile and upload firmware to such boards (including our GRBL-AIO).ĭownload the latest Arduino software here.

The Arduino software is the simplest way to install drivers for most serial devices used by Arduino compatible boards (although not out GRBL-AIO). Step 1 – Download Arduino Software, if not already installed.

These are the quickest most foolproof steps to take in updating GRBL onto an Atmel based board like Arduino, the GRBL-AIO and others – basically, any board that runs GRBL will be updatable following this guide. It’s very hard to damage anything so just give it a crack. Much of the information represented below is taken from the GRBL Github Page, and been updated to include more detail for those doing this sort of thing for the first time.
