Most of the code has been taken from the TapChanger repo.
You need homing.cfg, macros.cfg, tool_detection.cfg and toolchanger.cfg from TapChanger Example
You can either add them manually to your klipper install, or alternatively, you can integrate them to your config so that moonraker keeps them up to date with your other software if they change. Below are the steps for the integrated way. If you make any changes to the files though, they will be overwritten if you update. If you choose to manually add them, make sure your printer.cfg reflects the location of them.
On the Klipper System
cd ~
git clone https://github.com/viesturz/tapchanger.git
ln -s ~/tapchanger/Klipper/config-example ~/printer_data/config/tapchanger
Add to moonraker.conf

You must install klipper-toolchanger, Follow instruction on the linked page.
Toolchangers start with number 0, and count up. So for all the configs, make sure you change all sections. IE, in your T1 config, make sure its extruder1, fan1, etc. See the examples. NOTE: The only except to this rule is T0 extruder has no number.
