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.
