Hi all, jumping on this thread now that I have got my AMS.
I was actually wondering, the RFID includes the information also on the colour, so it would not be possible to just reuse any PLA support, for example, because you would get the wrong colour. If there is no way to program an RFID you would need an empty spool for each colour/material, which is not really doable.
Also, with the AMS there were four empty spools (very nice!), which I guess are without tag. It would make sense to be able to add it to them.
