Thats similar to what my plans are. Am thinking of putting PETG in the HT and PLA in the ASM2.
So far the only thing neither ASM or HT can do is feed TPU, has to be hand fed to the extruder, which if not mistaken is the head unit. I haven’t used any yet, nor have any, but from what I gather, the TPU should be dedicated to the left head only and be the only filament connected at that time.
