When doing dual extrusion there are many ways to go about it. The basic requirements are that you have a board that supports 2 Extruder connections, 2 hotend connections, and 2 hotend thermistor connections. However, if you are using a 2 into 1 adapter you only need a board that has 2 extruder connections. We are going to go over what you need for each setup and the pros and cons of each. Personally, we prefer the 2 into 1 setup due to its ease of use but they all have their advantages and disadvantages.
We do not provide technical support or assistance for Dual Extrusion setups, however, we do have a community support channel set up on our Discord Support server. You can click HERE to join.
