To make this step easier, we already made the necessary modifications to the last current (1.1h) GRBL version for you, disabling the third axis. As a result, when it goes to home the "Z" axis, it never proceeds to the next step as it physically cannot trigger a limit switch that doesn't exist. An off-the-shelf version of GRBL however, assumes we have three axes, not two. To actually have something to flash to the laser, you'll need GRBL. You'l need to install Arduino IDE through the appropriate installer for your system, but the specifics will vary computer to computer. As a toolkit to enable microcontroller development in a friendly bundle, it allows you to make any changes we might need to make, connect to the laser, and send the new version of GRBL to your device. To flash a newer version of GRBL to your laser, you'll need to download Arduino IDE. Not doing so will cause flashing errors later in this process. Copy those to a text editor like Notepad or TextEdit and save for safekeeping.Īt this point, please close LightBurn. This gives you a further verification step to make sure the laser's behavior is as intended after flashing. Using the Console, you can enter "$$" to get the GRBL values of the machine to supplement those from the Machine Settings window. This allows you to save a backup of the laser's configuration that's know to work before we flash firmware and reset all of those settings. In this window, you'll want to click "Save to file". In LightBurn, use the macro created in the Limit Switch Guide to apply the needed limit switch firmware changes, and afterwards use the Edit -> Machine Settings dialog. Plug in your laser's power and USB, connect it to your computer, and open LightBurn. Read the whole guide, start to finish, before trying to flash your machine. Flashing your firmware incorrectly can damage your machine. To successfully flash your laser, high attention to detail is needed.
