hi, while looking for an open source IDEX solution, I stumbled on the teaching tech video.. the proforge 2s with switching extruder may actually be exactly what I was looking for. it's a bit unnerving though that there don't seem to be any reviews yet of the switching extruder setup. so I was wondering, perhaps there's someone in the forum with a working setup, who'd like to share some of the experiences in using it, and possibly even some close-up pictures of printed parts? thanks, cheers! mark.
