I have a X2D with 2 AMS Pro’s and the filament track switch. Just got an HT and the recommended 4-in-1 PTFE adapter. Not sure the best way to use it.
I’ve seen many options on MakerWorld for my printer, but none of them also utilized the filament track switch. If you use Bambu’s recommended mount for the track switch, it sticks out several inches on the right rear. Bambu also recommends for my configuration (3 AMS’s, the HT counts as 1), that you use the 4-in-1 PTFE adapter on the input side of the filament switch. To do so means it just hanging in the air, not good. Anyone tried this configuration? On option is to make another mount for the filament track switch with a longer tongue so I can mount both the switch and the PTFE adapter in line. Suggestions?
It’s not an issue if the adapter hangs in the air. Mine does too on the H2S, and it’s completely fine. I would recommend 8-10 inches of PTFE tube sticking out from the inlet on the printer. That way you will get a wider radius on the PTFE tube the adapter hangs from, which means less friction and less chance of forming a kink on the tube.
I have my 4-way adapter free-hanging and no problems. I don’t have a track switch, it simply connects to the buffer via a short tube about 70mm long.
I have 2 x ams and 1 x HT on my X2D and my 4-1 is also hanging in the air . As yet it’s not been a problem , in fact it maybe better than fixing it statically as the tube and adapter can move around a little as the filament gets loaded .
I also have the FT switch by the way .
I ended up having my main AMS 2 Pro feeding one side of the track switch and my second AMS 2 Pro and my new AMS HT feeding the second switch input thru a 4-in-1 connector. The connector is just free hanging as others suggested and works fine. But this configuration does have one limitation. You can never use both AMS that feed the 4-in-1 connector simultaneously. It’s one or the other (essentially one bank). So, while Bambu says you can use up to 4 AMS 2 Pros, you would have to bank them 2 per bank and only be able to use one AMS per bank as the 4-in-1 adapter is only 1 path.
I discovered this model and for me it solves everything I can wish for. For me it has made the FTS completely obsolete. You can assign all AMS to the nozzles in any combination. E.g. all AMS main nozzle or AMS HT to AUX, AMS2(a) + AMS2(b) to main. AMS2(b) + HT to main, AMS2(a) to aux …
It just needs a flick of the respective sliders and 10s to rearrange the AMS on the printer or alternatively, automatic detection of the assignment.
It really works flawlessly for me with minimal resistance.
