I just got the P1S combo with the AMS 2 Pro, chose the hub option over the buffer. So this comes with the hub, switching adapter and the 4 pin cable. If I want to add an AMS HT down the road, what do I need besides the AMS HT? From what I can see the hub allows the connection of the AMS 2 Pro and the AMS HT for filament feeding. The AMS HT has a power cord so I assume that I don’t need anything else for it. Do I need to have all 3 items, the AMS HT, the P1S and the AMS 2 Pro plugged in separately? Or can either the switching adapter or AMS HT itself power both of them together? Thanks.
