Rooting the Nebula Pad

Once you have installed the Nebula Pad on your printer, you can "root" it. This lets you make tweaks and enable extra features that are not available in the default firmware.

At Your Own Risk

3D FDM printers involve high temperatures, molten plastic, and electricity. Improperly done modifications may not only break your printer but may cause damage, personal harm, or death.
