This model implements a the cartographer probe, and by proxy likely a beacon probe for z probing and bed meshing. This has been tested for several hundred hours on pretty custom formbot explorer printer and works pretty nicely. There are two models, one for doing the RGB LED modded tool OR stock LEDs. 

Step 0: Determine your canbus uuid or serial

Once you have the carto installed, you should be able to navigate to the devices section of mainsail, refresh the list,  and find your appropriate ID. If you do not find it, do not proceed to Step 1. You need this to proceed. Once you find it, make note of it and proceed. 

Step 1: Config, Macros, and Overrides Installation

Navigate to machine > Config Files, and click through to /config/01__User_Custom__CFG. Create a new file named carto.cfg and press create. Paste in the following configuration. In the cartographer section, uncomment either serial or canbus lines to add your reference from step 0 above! Critical or you'll make klipper real sad and it won't start on restart.

Save the file, do not restart! 

Step 2: Include the new carto config

Navigate to the config file root folder and edit the printer.cfg to include our new carto file. Locate the section that starts with this banner:

#### --> User custom CFGs <--################ ############### --> Added by the user <-- ###

Paste this line below that:

[include ./01__User_Custom__CFG/carto.cfg]

Save, but do not restart yet! 

Step 3: Follow Carto Software Installation Instructions

Start here →  https://docs.cartographer3d.com/cartographer-probe/installation-and-setup/software-configuration/klipper-setup

From the CLI using SSH, you need to copy and paste the command referenced in the Installation Klipper plugin section. Once this completes without error, you can quit the terminal section. 

Next you do the section headlined with Configure Moonraker Update Manager. You can do this from mainsail in the config editor section as the moonraker config is in the root of your config directory. Just copy and paste the block to the end of your configuration. 

SKIP THE SECTION HEADLINED WITH Configure Klipper!!! We did that in Step 1! 

Finally, click save and restart. Klipper should start back up normally and we are ready to proceed.

Step 4: Carto Calibration!

From here, you are implementing cartographer as documented from their docs. Just click the next button at the bottom of the page from the link in step 2.
