I’m thinking of building a new printer and would love to be able to make 2 color prints or dissolvable supports. Does anyone have any experience with this. I see 3 paths.

  1. Two hot ends Pros: Most robust No retraction or filament waste Cons: Alignment issues. Reduced travel Dragging nozzle

  2. Dual filament hot end(taichi style) Pros: Easy to mount No offsets Cons: Jamming? Long retraction

  3. Y splitter Pros: easy to mount No offset Compatible with any hot end Cons jamming Super long retraction

    No, the trinamic system I’m talking about is end stop phase counting in tandem with physical limit switches. It’s pretty accurate, one thou repeatability, like I said.

    But like you point out, repeatability of the home position is not so useful if the axes of the two heads aren’t aligned in the first place. That’s a hardware issue that’s not going to be solved with encoders or software.
