Hello, I saw the AMS 2 product page says it can support 24 colors with 4 AMS 2 units and 8 AMS HTs, but I am not sure how those would all hook up to a H2D.
Does an AMS 2 have ports to add on an AMS HT? Can AMS HTs connect to eachother somehow?
The wiki and product pages aren’t very clear about this.
You buy a separate AMS hub from BBL and connect your AMS’ to that hub and that hub to the printer.
I agree. The math doesn’t make sense to me either.
Since the only hubs they currently sell, are 4 to 1, I don’t see how that evenly distributes to 24.
or you print something like a Smoothy or something like this 4-in-1 PTFE Adapter by jusutus - MakerWorld and chain them
Still doesn’t fix the math.
To get 4xAMS2 and 8xAMS HT you need 12 inlets. Their buffers allow for 4 so you would need 3 to allow all the inlets. But, the H2D only has 2 intets - so how do you bridge that gap? A diagram from Bambu would be great!
What do you mean?
AMS data cables daisy chain. you only have to worry about the AMS feeds
you have 1 input port. you get a 4:1 splitter. then you get MORE 4:1 splitters
4x 4:1 into a 4:1 is 16
then you connect that 16:1 aggregate to another 4:1
then connect two 4:1s to the other legs of that 4:1
now you have 27:1
From the 3rd FAQ question and answer.
3.What is the maximum number of AMS 2 Pro and AMS HT units that the H2D supports? How many colors can it print at most?
The H2D supports a maximum of 4 AMS 2 Pro and 8 AMS HT connected simultaneously, a total of 12 units with 24 slots.
Because H2D is a dual-hotend printer, and in the most extreme scenario, all AMS can be connected to one hotend while the other hotend uses an external spool holder, it can support up to 25 colors.
Your math still makes no sense.
4 AMS2 x 4 colors each needs 4 inputs for 16 colors
8 HTs needs 8 inputs for 8 colors.
4 + 8 = 12 inputs
Unless the printer in question has 3 inputs, you’re your 4:1 doesn’t work without leaving an input unutilized.
Feel free to draw a diagram to prove otherwise. ; )
the AMSes each contain a 4:1 internally, you’re just not following. let me get back to you in a few with that drawing
I appreciate your quick mock up, but I think you missed my point.
Leaving an unutilized input makes no sense.
The only thing that could possibly cause this limitation would be device addressing.
And the number 24 or 12 doesn’t make any sense either as a software device addressing limitation. 8, 16, 32… Makes sense software-wise. Not 12 or 24.
oh they probably can address hundreds, they just are only certifying 24 because that is what they’ve tested and want to officially support.
my product once certified in pre-release that we supported 4000 of something, our competitor announced “Hah we actually support 6000! we’re better” and in final release we announced 8000
we had tested over 25,000. it came down to just what our PM team was willing to publicly declare support for.
I will concede that possiblity.
But having a degree in computer engineering, I can’t think of a single software/hardware engineer that wouldn’t utilize all the inputs in your diagram to bring the supported number to an actual round binary value.
24 is not a round binary value.
I have a hard time believing that a serial bus is only going to support 25 devices.
like i said- because it’s not a limitation of the serial bus
it’s a limitation of the PMs/testing
i thought you were originally confused about connecting.
If I remember right, 24 comes from 4x AMS 2 pro + 8x AMS HT.
And don’t forget the two nozzles! So it could be something like 2x AMS 2 pro + 4x AMS HT on each nozzle.
Maybe you can join 2 AMS HT with a simple splitter into one AMS hub port?
It still isn’t fully logical though.
The limitation might also be based on the user interface. Maybe they decided that more simply becomes too confusing to manage.
Well your diagram also implies that hubs can also be chained together.
I’ve yet to see any documentation to show how that would work unless there is a different hub that they came out with.
The four-port hub I have has only a single four pin connector and six pin connector.
So I’m not sure how they could be daisy chained together.
And I believe that goes to the root of the OP.
I think somewhere it was mentioned that those 4 way splitters they sell are the way to achieve this and not the 4 port hubs.
the only difference between the hub and a filament buffer is that the hub contains a 4:1 combiner
you use AMS lite combiners/printed equivalents and don’t use a hub.
don’t chain hubs/filament buffers.
