Hi Max,
Thanks for contacting us and sorry for keeping you waiting.
We’re already working on the development of a dual-extruder module for Snapmaker 2.0. Hopefully, it will be available by the end of 2022.
Hoping my explanation can assist you. Please feel free to let us know if you have any further questions.
Kind regards / Eamon
