Repetier settings for DaVinci 1.0 3D printer

Here are my settings for Repetier 1.6.1. I have used these settings through all the versions over the past year on my DaVinci 1.0 3D printer. Repetier is a powerful aftermarket software used to control the printer. It voids the warranty and if used wrong could damage things. Use at your own risk! With these…

Unlock the potential of your Dji with the Litchi app
