X2d + Ams 2 pro + AMs HT : Connexion PTFE

Hello,
I’m trying to figure out how to connect the PTFE tube to an AMS HT and an AMS2 Pro, all on the main nozzle of my X2D printer.

I’ve only been able to use the AMS HT by connecting it through the auxiliary nozzle!

I have a Bambu 4-in-1 switch, and both my AMS units are powered by an external power supply.

Slicer used: Bambu Studio version 2.9.1.70

Thank you for your help and/or schematic. Happy printing everyone!
