I've been in the market for a 3D printer for a while - UM1 was too early for me but UM2 ticks so many boxes. I'm no engineer nor have I been up close with the product but I would like to hear from engineers especially, on a scale of 1 to 10, how feasible is it realistically to get a rock-solid solution to dual extrusion to work on the UM2? Does the current layout lend itself to this or is it like trying to fit a square peg in a round hole? Do we have the materials and technology to make this work so that it's just a matter of getting them to play nicely? I know Ultimaker are doing all they can and I don't mind waiting a little - I'm just looking to make the investment a little more futureproof. Thanks in advance
