Step 1 – power on your CNC machine, launch Universal Gcode Sender and connect to your machine. The following steps oultine the process to save a copy of your GRBL settings. You don’t want to start from scratch and have to redo all of your work. You have likely spent time tuning these settings for your machine. When you make the update to v1.1, all the GRBL settings will be reset to defaults. The first step in the GRBL Update process is to save a copy of your existing GRBL settings. Each of these are detailed in the following sections.ģ – Install and Test Universal Gcode Sender V2.0 Classic (or Platform)Ĥ – Remove old GRBL files from Arduino IDEĦ – Update GRBL Settings SAVE Your GRBL Settings I used the following steps in my GRBL update process.

If you have not setup your Arduino based CNC controller, click here for a detailed post on setting up your controller. The changes in GRBL v1.1 make this software version incompatible with older versions of UGS. If you decide to update to GRBL v1.1 you will also need to update your version of Universal Gcode Sender (UGS) to either 2.0 Classic or 2.0 Platform.

After all my CNC mill is a tool to be used. At this point, I would rather spend my time making parts than fiddling with my machine. The simple answer: my machine worked, and I didn’t want to break it. You might be wondering, “Tim, why did it take you so long to make your GRBL update.” After all, GRBL v1.1 has been out for a long time. Hopefully, this will save you some time and frustration. The following details the lessons I learned. I made the switch from GRBL v0.8 to v1.1 a few months back. STOP! Before you do anything, save a copy of your GRBL settings.
