Do I need the Bambu 4-in-1 PTFE Adapter for 2 AMS HT and 1 AMS 2 Pro?

Bambu Lab H2 Series
1

I am purchasing the H2C, 2 AMS HT, and 1 AMS 2 Pro.

I think I need the Bambu 4-in-1 PTFE Adapter, but I want to be certain.

Is there anything else that would be advised to get when purchasing these 3 items?

Can anyone advise, please?

You’d need something as you have three tubes for two paths. I utilized the BL original adapters. They were not great. Error after error. I checked with the members here and was guided towards the online improved designs. I now use these and can attest, they are much better than the BL made devices. A simple print and build. Amazing difference. I get zero errors now. Something to consider.

Indeed, you’ll need to use one to hook up 2 AMS units (HT or Pro) to one nozzle. Good news is that one is already included!

(in “Tool Box” for combo and “Supply Box” for laser version)

Is there anything else…

Filament! :slight_smile:
But no, not really… pretty much everything to get started is included.

I’d recommend 2 ams pros and one ht. H2C has 7 nozzles…

6 on right and 1 on left.

I have ht connected on left and 2 ams pros on right giving me an extra 2 slots.

@NicPlays3D Thank you for responding!

I looked at the model for which you provided a link and it has only 2 areas for filament to enter.

Looking for at least a 3-piece opening, I found this: PTFE Bowden Y Splitter (3 way) - Free 3D Print Model - MakerWorld

I wonder if the new, updated 4-in-1 PTFE adapter would be better than the original adapters you mentioned.

Do you have any experience using the most recent version of the 4-in-1 PTFE adapter?

@MaxThreeD Thank you for responding!

I definitely have the filament needs covered. :slightly_smiling_face: I am not really sure how I came to possess so much filament, but I think it was from sales occurring and me saying, “Of course, I will use this filament so much that one (1) roll might not be enough!”

Thanks for letting me know about what is in the toolbox.

I was also considering getting a rubber mat to not just reduce the shaking of the table on which the 3D printer will be, but to also keep the desktop clear of any scratches from a lightly mobile printer.

I feel like I am forgetting something, but I cannot remember what it might be. I hate that.

@cr8dev Thanks for responding!

I have thought about doing that (2 AMS Pros and 1 AMS HT), but I am not sure I want 2 AMS Pros taking up so much room.

I am wondering, however, do you know whether the left nozzle can be hooked up to 2 AMS HTs?

I must admit to being a bit baffled about how the setup would occur:

  • 1 AMS HT on the left nozzle and

  • an AMS Pro 2 + AMS HT on the right.

Can the H2C figure out what filaments are where and to what hot ends they go?

My desired use case would be the following:

  1. one (1) filament type or color for the left side;
  2. 4 colors for the right side;
  3. 0.4 mm nozzle on the left (or a 0.2 mm or 0.6 mm, depending on my situation);
  4. 4x 0.4 mm nozzles on the right;
  5. a parked 0.2 mm nozzle on the right (used when applicable); and
  6. a parked 0.6 mm nozzle on the right (used when applicable).
  7. I also plan to print with dissolvable support filaments.

I assume this is doable, but I am not certain, and when I think about it, I think:

  • Why would I be getting two (2) AMS HTs when the plan is to print with 4-5 colors/types of filament with 0.4 mm and 2 colors/types with either a 0.2 mm or 0.6 mm nozzle?

I think I am overthinking again.

I run my H2C with two HT’s on the Left nozzle and two 2Pros on the Right. That gives me two filament choices for the left and eight on the right. Considering the nozzle layout for the H2C, that’s plenty for me. I utilize the Smoothy to guide the two HT’s to the Left side and a Smoothy to guide the two 2Pros to the Right side. I have ZERO feeding issues.
I used the new BL 4-in-1 and had feeding issue after feeding issue. I also used the new BL FTS. HUGE amount of feeding issues with that. I pulled all that stuff and just built out a couple Smoothy’s and started calling my Uncle Jake “Bob”. Works beautifully.
Ultimately, you’re free to utilize whatever you personally choose. I’m just letting you know my experiences. And with the way I work, this is the best solution.

Haha, yes well, you’re not alone there… can’t print from an empty shelf! :sweat_smile:

The feet are pretty grippy already (mine doesn’t slide at all during prints) and don’t mar the surface, but I suppose it could depend on the surface (eg. very glossy) :slight_smile:

left nozzle can be hooked up to 2 AMS HTs?

Yes definitely. Also the 4-in-1 (or “N-in-1-out”) adapters can be daisy-chained into each other to support up to whatever the maximum is per printer overall… This shows the concept, though they’re hooking all AMSs to one side here: https://wiki.bambulab.com/en/ams/manual/multi-model-AMS-compatibility-guide#h2-series-ams-connection-guide

The N-in-1 inputs can be from any source of course, like spool holder or other drybox, not just AMSs.

Essentially, yes… If using BL filaments, the AMS(s) will report to the printer what is loaded into each slot. With other filaments you’ll need to tell the printer what type & color material is in the slots. Between slicing the model (choosing nozzle size, assigning colors/material in the slicer, etc) and sending the job to the printer, this all works out in the end and is quite flexible. The final step when starting a job will be verifying that the desired filaments (AMS slots/external spool) are actually chosen and which nozzles they’re mapped to.

This is maybe the most concise summary of the overall process: H2C Bambu Studio Operation Guide | Bambu Lab Wiki

My desired use case…

That all sounds perfectly reasonable (basically my setup as well). I don’t see the 2nd HT being used in there… unless you mean that’s for the support filament :slight_smile:
Putting multiple filaments on the left nozzle really only makes sense once all Vortek nozzles are already being used for a print (> 6 materials or one doesn’t have enough of a particular induction nozzle size)… until then you’d be wasting time/filament by having the left nozzle do any swapping.

Just to be clear, currently there’s no way to mix nozzle sizes in one print. We’re all waiting on that feature with bated breath.
But yes, having the different nozzles in the rack and ready-to-go for a print is super nice, not to mention that swapping one on the rack is 1000 times quicker than swapping left side nozzle.

I feel like I am forgetting something

Nah, you just probably haven’t though of it yet… :laughing:
