My use case is this. I have two 1st Gen AMS, a single AMS2 Pro, and just paid my money for the HT.
I also have a Sunlu S4
The two old AMS units will have filament and colors I use regularly. Which is generally going to be neutral colored PLA.
The AMS2 will hold my favorite filaments that require drying. They will have been pre-prepped for the AMS2 by spending some time in the Sunlu.
The HT will probably be dedicated to TPU.
THE Sunlu will hold infrequently used filament requiring drying
Which flavor of fruit loops do you like the most?
I ordered an AMS HT but will never use it for TPU. I’d rather just leave it empty than feed things out the back of that hokey bypass port. Given the problems Joel had the cereal box is much more flexible in placement.
Someone suggested TPU as “one reason” to buy an AMS HT but I don’t see it as compelling reason.
I dont see why we couldnt dry tpu while using the bypass. By telling the printer it is printing from the side spool holder and turning auto rotate off. Or any filament really.
If I understand the question, it cannot. I’m guessing you are saying to put used “wet” silica gel beads in a cereal box with dry beads?
All that will happen with wet and dry beads in the same container is the wet beads will dry and the dry beads will get “wet”. The moisture content in either set of beads will move to an average value for all the beads in the container.
I accidentally did that experiment. I use silica gel beads to dry air that gets purged into my filament dryer. The way the drying process works is I get very “wet” beads at one end of the silica gel column while the beads are mostly dry at the other end.
When I changed out the beads the first time I poured them all back into the container they were originally packed in and you could easily see bright orange and dark green beads. After a day they were all uniform green color and none were still orange (“dry”).
Sorry, I meant the ams ht could dry its own desiccant. The other part was a jab at the amazon hygrometers that only go down to 10%
I generally don’t eat cereal… I’m not supposed to 
My Tech Fun did an experiment where he stored his filament in a partial vacuum in one of those vacuum containers, and it still gained enough moisture that he says he has to redry it every time before using it. So, if that’s the case, maybe something which can both store and dry filament really is better than a cereal box. Just sayin. Not saying it has to be this though. For instance, he didn’t put desiccant into his vacuum storage box, so maybe a cereal box with lots of desiccant is the ultimate winner.
With a sack of good desiccant in the cereal box, the desiccant will probably be “more dry” than the filament and will still slowly dry the filament along with scavenging any water that leaks/diffuses in until equilibrium is reached. Slowly because room temperature.
About using lots of desiccant - it won’t get your filament any drier. Lots of desiccant just increases the capacity to hold water so it lasts longer but it’s also more desiccant to dry when it does get loaded up.
I think the key to this stuff is effectively drying the filament in the first place.
With the AMS HT being able to set drying parameters from the tags, being able to clone them is suddenly useful. Need to order some more blanks.
I have just received an AMS HT which I have had for about a week now. The main reason that I was triggered to purchase the unit was the drying function, and I have not been disappointed. It works fantastically in my opinion. The interface on the X1C is logical and I found it easy to use. Not sure how it would interface with the P series printers.
Adding a 5th AMS bay to my X1C was a bonus, and so far it is working as expected. I put in a backup filament in anticipation of a spool running out, and it fed in flawlessly.
I have a Solvol two bay dryer and a Polydryer which I will carry on using, but if I have a filament that I want to ensure is as dry as possible the AMS HT will be the goto option.
It’s pure luxury, but I really do like the “easy load” capability of my AMS 2 Pro. It’s such a nice convenience. Does the HT have the same capability and behave the same way? It’s like comparing advanced electric car windows to the manual type. Just tap the button and it rolls the window all the way up or all the way down. Except, of course, even better than that. 
The pimp factor alone makes it worth considering. 
My printer mods are impressing totally the wrong demographic, I hope the AMS HT will do the trick!
I was planning to buy one until I saw that it doesn’t support all carbon fiber filaments. I’m not concerned if it shortens the lifespan.
I just want features like power windows 
I personally paid for the HT as soon as it was available (still waiting for it to ship).
My reasons that personally, it’s a “must have” due to my printing engineering filaments mainly:
I have various filament driers that can be printed from, the best one in my experience until now for engineering filaments is an original “Eibos Cyclops”.
But they are all kind of “clunky” and “cheap”, even though they are somewhat costly.
We all know the Bambu QOL standards, and the tendency of their products to do what they say it will, so the HT is a no-brainer.
I’ll just stash the Eibos and Sunlu where nobody can see them while the HT and AMS2 Pro duo impress one and all with their snazzy look and feel along with the groovy, soothing mechanical noises they periodically make while working with the boss HD2.
I like the ams ht so far. It lets me dry some of the filaments I have at the proper temps.
I just ordered 2 more of them today to replace one of my ams1 units on my x1-c. I’ll give the ams1 a refresh and throw it on one of the other printers. Or maybe sell it, idk yet.
I was thinking about installing the lighter extruder springs in my older AMS-1 to improve its ability to handle TPU 95A filament.
Just to have TPU power windows
Which ones? I’ve been running various gf and cf not mentioned as supported through it and it hasn’t tried to stop me.
Hi Monger.
My AMS Pro 2 can handle some carbon fiber filaments 
, but I was hoping the AMS-HT would be compatible with like the Siraya Tech PPA-CF Core. I know the AMS Pro 2 can’t handle the core filament because of the feed tube angle I tested it myself.
I’ve been considering modifying the AMS-HT to create a straighter path out of the feeder. I’m not too concerned about the heater since I already have filament dryers. I was waiting to see if any photos or videos of it taken apart would appear online or to find out what users are discovering with some stiff CF filaments.
Perhaps the HT-AMS has a better filament path or a more powerful extruder motor I’m not sure. However, even Bambu’s own website mentions using the bypass port for certain carbon fiber filaments.

Does that change your mind at all?
That why I’m not joking that in my case, I’d only do it for the power windows…and I still might. The added convenience is worth something.
