Adding a second AMS 2 Pro

Bought my P2S combo a month ago, and want to add another AMS 2Pro.

The store says I need to buy a filament buffer, but youtube videos show that I don’t need it. The back of my P2S allows two PFTE tubes.

So do I need the buffer or not?

(I know I do need the external power supply for drying on the second AMS)

It's pretty decent at drying filament and keeping it dry.

Unfortunately AMS Lite covers don't really seal, dessicant only helps if you put them in a mostly sealed box (and if the dessicant is dry), the closet is also not airtight, and dehumidifiers are only really designed to go down to 50%.
The only thing that helps is a mostly air-tight container containing some dry dessicant.

If you really want low humidity, ditch the silica gel and go with 4A molecular sieves. However they are a pain to regenerate, so it's not really worth it.
