Noobie here. I have the AMS working great, but I also want to print with TPU…I have the AMS hub with 4 intake slots…can I feed tpu thru one of those or do I need to use the Y splitter?
Second question…can one multifilament print with the TPU and rolls in the AMS? If so how do you change the filament mid print?
Thank you
I don’t see why you can’t feed TPU through the hub, as it is entirely passive as far as the filament is concerned. But it is easier, I think, to disconnect the tube at the printer input and feed from there (shorter distance and fewer turns.) Or you could use a “splitter”. I don’t see any way to combine manual feed with AMS, however. That would be a great feature request.
Ah thanks, I guess the real objective was to see if I could combine a print with partial tpu and a nylon. There doesn’t seem to be a means to do so right now.
Much appreciated
I think this is a hard thing to accomplish. Retracting TPU its always a challenge, however this might be possible. I haven’t tried it.
Would be cool!
I remember reading somewhere that TPU will not work with the filament tensioning in the hubs so you shouldn’t feed TPU through it.
I should have done a better job of searching first, but I just made a feature request for functionality similar to what you’re describing. Hope Bambu Lab can implement it as I would imagine its fairly simple to do:

Good question, I wondered whether this approach could work too, as I was thinking of making a dedicated single reel feeder and a better filament path combined with the hub that could hijack an AMS port.
In theory you could add the second connector to the AMS and use this to power & control a single extruder.
Just need to analyse the signals and gcode used on the AMS
