GRBL 1.1 update for SO3 Sparkfun Edition?

Hi all,

I own a Shapeoko 3 Sparkfun Edition. Is it possible to update that one also to GRBL 1.1? If so, can one of you point me to documentation on how to do it?

I believe this will be the same as doing a Carbide 3D board — there’s explicit mention of entering a Sparkfun code at:

Finally got around to updating my Sparkfun SO3 to GRBL1.1, and am posting here so that others might avoid the issues I encountered.

The Carbide Upgrader does not work, as it will not recognize the Stepoko (Sparkfun Arduino board).

I found great, detailed instructions to updating GRBL via the Arduino IDE at:

Appreciate you taking the time to share this. Super useful!

I also have a Sparkfun edition. Do I have to fit homing switches first?

I would try the Arduino update.

Best wishes

If you wish to use Carbide Motion 4, you’ll need to have homing switches.

If you’re using some third-party G-Code sender, not necessarily.

You really should get them, they’re a huge improvement/convenience

Thank you. I will look into switches.

Using the IDE what board do I select? UNO??

Best wishes.

Please see: GRBL 1.1 and Carbide Motion 4 and the following post and https://www.shapeoko.com/wiki/index.php/Grbl#Downloading

Thank you for trying to help. But I am getting a little confused.
Do I upgrade using
Hex loader + Hex file
Or
Arduino IDE + Source file target board uno.

Best wishes.

Whichever you prefer. They’re all valid.

Just wanted to say Thank you William.

All sorted.

For anyone else that needs help.
I am using a macbook.
***Make sure you copy your existing GRBL settings ($$) somewhere as they will need re-entering after you upgrade.

I used these instructions https://github.com/paulkaplan/HexUploader/wiki/Using-HexUploader
Download the app from here http://paulkaplan.me/HexUploader/
Download the 1.1 GRBL hex file from here https://github.com/gnea/grbl/releases

Make sure you have the latest version of Arduino from here https://www.arduino.cc/en/Main/Software
When unzipped and installed - Make sure you copy the program to your Applications folder.

Run Hex uploader.

When completed. manually update your GRBL settings from the settings you saved at the beginning.

Best wishes.
