First things first: you're going to need a copy of Repetier.
If you are upgrading an existing 3D printer to use a Titan, you should try to get a copy of your current firmware from your printer's manufacturer.
If you're building a new printer, or simply want to upgrade to the latest version of Repetier, download it at https://www.repetier.com/download-now/
If you download a fresh version of Repetier you'll have to configure more settings than the ones mentioned in this guide so that it will work well with your printer.
