Loading GRBL on Arduino Mega or Uno
December 21, 2019
There are a couple methods to load or install GRBL on an Arduino Mega or Uno. The most common method (which is described in the GRBL Wiki) is to use the Arduino IDE by copying the GRBL files, loading a sketch, then finally uploading. A far easier method is to use XLoader, pick the file, and click upload. This method is also in the GRBL Wiki but it is buried on the page and seems to be discouraged, plus the link to XLoader is broken.
Downloads:
- XLoader
- GRBL 1.1f (standard version for Arduino Uno)
- GRBL 1.1f (standard version for Arduino Mega2560
- GRBL 6 axis (6 axis version for Arduino Mega2560)
- Arduino Mega2560 bootloader (stk500boot_v2_mega2560)
Here is the XLoader interface. Select the .hex file by clicking on the button with the dots, pick either the Mega or Uno device, select the COM port, and click Upload.
