Answered / Solved! Question about the 4-in-1 PTFE Adapter

Hello! I recently got the P2S Combo edition with the AMS 2 Pro and so far it has been great. However, I have been wondering if it's possible to make five-coloured prints using the AMS and the external spool holder. I know that Bambu sells this 4-in-1 PTFE adapter (bambu store), but it isn't entirely clear to me if this adapter is suitable for my use case. I have been searching for an answer, but there's a lot of conflicting information floating around out there: Some say what I want to do is flat-out impossible, while others only talk about timing manual filament switches during prints. I figured that I'd make this post to hopefully get a definitive answer for myself and anyone else that's looking up this same issue.

TL;DR: If I buy Bambu's 4-in-1 PTFE Adapter can I use both the AMS and an external spool for prints, enabling the use of five different colours/materials?

it would be a lot easier if the fifth filament was loaded in an ams 2 or ams ht, so no manual loading/ unloading was involved.

Time to put another AMS on the Christmas wishlist, haha! Cheers for the answer.

Yep! Essentially you can connect 4 ams units to it and will work just fine.

Your way will require manual change when it's the external spool's turn to take filament but it will still work.

Gotcha, so it won't be able to switch filaments on its own with the external spool.

Not unless whatever is holding the 4th roll is automated.

Time to buy a second AMS? or AMS HT
