If you have only the one AMS 2 connected to the back of the H2S, is it possible to connect an external spool to the other AMS port? I don’t have an H2D, but looks like it has only one AMS input, but it appears there are two AMS outlets on the back of the H2S. Just seems like it would be easier than removing the AMS 2 tube and inserting the external spools tube, which I have done, and it works. I haven’t found anything in the wiki one way or another.
no, that does not work, as the h2s is only a single toolhead printer, it is just a leftover from the h2d
