people seem to be a bit confused here.
when people are talking about the lack of a motor they are not talking about the first stage feeder.
they are talking about the spool reels.
if you need to retract a significant amount to get past a hub that is mounted in a decent place. (so not dangling above the print head). then the retraction distance to get past the hub can cause an issue where the filament gets tangled on the spool.
the thing is though.
in reality on a full spool. the print can retract about 140mm (the motor does the retracting. but the spring keeps it tight on the spool)
on a nearly empty spool this is obviously going to be less. (about 70-80mm) but i do think it is possible to put a hub in there. or even something like a Y splitter on each of the 4 ams lite hub connections.
basicly the spring on the spoolholder will rewind the spool about 80 to 90 degree’s of rotation.
with a radius of 85mm on a fresh refill spool. that is 133mm of retraction that’s possible. (and a little more up to 140 allowing the fillament to dangle a bit)
with a radius of 50-55 on an empty spool this will be 70-80mm of retraction.
with an empty spool. this is only enoegh to just barely clear the standard 4 slot hub that comes with the A1. so for new spools it wouldn’t be a problem. but for nearly empty spools we would just need an 8 tube hub in place of the 4 tube hub.
so yes it is 100% mechanicly possible with the current ams lite systems to have 2 ams lites on the A1 series.
the only thing holding it back is firmware support or at the verry least. someone trying and confirming that they do not detect a second ams lite.
other than that question. can you hook up a normal ams to the A1 series? if so then you can just use a hub and use multiple normal ams systems on the A1 series aswel. (as long as the firmware hasn’t locked it out)
so i think it IS possible. to hook up more than 1 ams lite to your A1 series. or even to hook up 2 normal AMS systems. BUT!!!
you are going to have to void your warrenty and install custom firmware.
