Changing EEPROM settings

For in-depth documentation on all of the settings in GRBL and what they mean, visit: https://github.com/gnea/grbl/wiki/Grbl-v1.1-Configuration.

You can make changes to your machine’s settings by changing the values in your EEPROM. These are settings that will persist even after you power off your machine and control things like the maximum speed, the acceleration, steps per mm, and more.

Start by sending the command “$$” to your machine. Your console will give you a list of values.

To change a setting, simply send the command that corresponds to what setting you want to change. For example, if I want to set my maximum feed rate in the Z-axis to 1500mm/min, then I would send the command “$112=1500”.

For advanced users, or users that want to add additional functionality such as with end stops and lasers, you may make changes to these settings.
