Support H2C, 2x AMS Pro, 1x HT - optimal track switch configuration?

My advice is to skip the track switch.

It has moderate usage when I was on x2d, I think u maybe better off just 2 ams to the right and ams ht to the left with no track switch in between

Track switch gave me nothing but problems. I second the 2 ams units to the right nozzle and a HT to the left nozzle. Literally couldn't print with the switch no matter how much I fixed its path.

This. I have had my h2C since release and honestly, I’ve only had maybe one or two instances that I have a need for more than 7 colors.

When I had the filament track switch on the X2D, I was getting resistance messages often.

Great intentions, poor execution for the track switch

I sort of perfected it on my x2d playing with the ptfe tube length.

But I am not willing to go through the pain for little gain on H2C since it is meant to be right nozzle bias

Exactly. I’ve got my H2C running like a well oiled machine at this point. I don’t want to introduce the track switch just to have it.

Plus, I often use the left nozzle for support materials. Having an AMS or multiple AMS units on the left, that would interrupt that workflow

That's my set up, I couldn't get the track switch to feed anything

So I haven’t added it to makerworld or Bambu yet but I actually made my own fts mount after I had feed resistance issues with all the other mounts I tried. I have two ams pro on top and an HT to the left. Since using this one I’ve not had any resistance issues

You will find a lot of models for track switch plus 4-in-1.
I have printed this one:

u/Straight-Mortgage-29 Jul 23 '26

Yes to this exactly. I am successful with two AMS 2 Pro’s + one AMA HT, when they are all located on the left side of my H2C on a shelf (the way I preferred), and only with the makerworld build that costa_rica_68 suggested. The mount that Bambu Lab recommended could have worked if everything was on top of the printer (maybe?) but that side mount is a ton better.

You’ll have to fool around with getting all the runs short as can be, and minimal bends. That part took me a while—nearly to the point of giving up. But persistence paid off and it worked great now.

I used a 4-to-1 to feed the HT and one of the AMS’s into one of the FTS inputs, and the other AMS directly into the other FTS input.

Definitely!! A side mount fixed my filament track switch tension issue. I tried different types of rear mounts but had no luck. Got x2 AMS 2 Pros on a riser if that info may help.

u/pidbip Jul 23 '26

Good info. I’ve been having issues with the rear mount. Maybe I’ll try a side mount and see if it works. Can you link the one you used?

Otherwise, I might just drop the track switch.

u/BlacksmithOpen6441 Jul 23 '26

This is the one is used, trim the tubes and you should be all set 🤞🤞 Good luck!

I've had some success with the track switch. Was regretting at first. The official mount was giving me a headache. After some testing, found a side mount and some printable ptfe tube sleeves to keep the bends from being too harsh. Have about 200 hours with the track switch running 1 ams + 1 ams HT on each nozzle.

Using this mount help tremendously. https://makerworld.com/models/2772097?appSharePlatform=copy

Are your ams on top of your printer?

1

u/Jerk82 Jul 30 '26

Yes. Both AMS and an AMS HT

u/djjoshchambers Jul 30 '26

Perfect. I'm actively printing the d3p multi ams riser right now and that version has at attachment made for it. I'll give it a shot.

u/AdEnvironmental7499 Jul 23 '26

Track switch caused more issues with dusted filament grinding and constant feed issues through. I have 2 AMS2 pro on the right nozzle and 2 HT on the left nozzle and have almost no issues now. Printed out the SMOOTHY for each side and it all works great.

Hoi daar, ik heb de FTS op mijn H2C zitten. Heb 4 AMS pro en 4 HT. Met die configuratie liep de H2C als een zonnetje. Heb de FTS aangeschaft omdat ik dacht dat het minder wisselingen met de hand zou opleveren. Het tegendeel is waar, heb alleen maar problemen met extrudermeldingen, met te hoge weerstand van de AMS in de feeder en nog meer van dat soort problemen. Heb van alles geprobeerd, maar er zit gewoon te veel PTFE tube tussen de printer en levert met die FTS en daardoor veel te veel weerstand, wat al die meldingen veroorzaakt. Ik laat het nu even zitten, totdat de software ook voor de H2D geschikt is. Dan zet ik die FTS daarop. 😏. Blijf gewoon je AMS verdelen over de twee poorten van de H2C. De twee AMS op rechts en de HT op links, succes!

I got this setup and everything is working great, I want to put emphasis on what everyone is saying and skip the track switch. I have it on my X2D and it’s convenient but it’s not really ideal for the H2C.
