I ordering one AMS-HT to test it out, and I’ll make modifications if needed. 
Do you have some known-to-be-taped filament spools to test it out on?
I haven’t run out of filament on the HT yet, but my AMS 2 doesn’t have a problem with the tape so far.
Let’s be clear: they are not worth the price they cost, but they do fulfill the need for drying and keeping filament dry during printing.
That said, they are unnecessarily overpriced. I currently own three AMS2 Pro units, four AMS HT, and two AMS units (the ones without active heating), and I plan to upgrade my older AMS units to AMS2 Pro as soon as possible, as well as add a fourth AMS2 Pro to my H2D.
It would offer much better value if the system could activate heating to maintain a specific humidity level—similar to what my AIBOS dryer does. That should be a relatively simple firmware update and shouldn’t interfere with the printing process.
Is there an upgrade path to do that 
, or by “upgrade” do you mean “replace with”? I too have an older AMS, and I like the AMS 2 Pro better. Who doesn’t? Providing an upgrade kit would be a nice gester, similar in spirit to what Prusa does.
I’m aware of this:
but it appears to be only good for connecting together multiple ams 2 pro’s for use by the legacy printers.
That’s exactly the point I was making earlier, above, and it seems very likely that Bambu Labs will enable those functions at some point.
No, it’s more of a replacement than an upgrade. 
Sure, an upgrade kit to turn the original AMS into a full AMS2 Pro would be nice—but I imagine most of the old components would have to be discarded and replaced with new ones. So instead, I’ll just go with a brand-new AMS2 Pro.
Holy smokes! I need this! Thanks for pointing this out.
[Edit] Oh man! It’s sold out?!?
It is just a few screws though… I probably already have them. Time to go searching.
It gets enough power from the 6-pin cable.
Heating you plug a 110V plug into it
I’ve read a bunch of people postt positively about the ability to auto-swap from one spool to another when the first spool runs empty. Those folks have had no issues with tape.
For anyone interested, the AMS HT is now back in stock. My order is listed as “fulfilled” but as yet doesn’t have any tracking info. To me “fulfilled” means received, but apparently to Bambulab “fulfilled” means shipped.
POOF! $192.50 of the children’s inheritance just went out the window!
Its really nice having the ht’s for rolls that get swapped in and out often. vs opening a 4 roll ams constantly and allowing new moist air in. As I have mine set up now, I barely even need to open a ams pro
Another small bonus
Same here. Ordered 8 and should be here by end of week from CA hopefully.
The HT-AMS display is nice; they should have included one in the AMS 2 Pro as well.
they should have just included a couple buttons so that i don’t have to initiate the drying process on the terrible bambu printer ui 
Not only does the printer have to be switched on to use the drying function … If one day you change the printer manufacturer, the thing will become a paperweight. I already have a dryer, I just wanted one for SPECIAL filament. But that really puts me off.
Sustainability is different.
