About the automatic tool setting problem of Toolchanger

[charles]

Hello everyone, I recently researched automatic tool setting on toolchanger.
By installing a metal block on the hot bed, let the edge of the nozzle touch the metal block to form a high and low level. Then calculate the xyz offset of each tool, and set the offset after getting the correct value, which seems to be similar to prusa XL.

Have a question right now?
How should I wire duet2 or duex5 and configure in config.g file
