I asked prospective beta testers to fill out a form and I noticed a trend that many wanted to have more than one extruder. I am sorry to say that the beta machines will only have one extruder. That is for a lot of reason. Cost being the number 1 reason. The extra extruder is cheap and the extra filament drive is cheap. The controller board is not. There is also the matter that my target users and the beta testers are not quite the same people. All that said I thought you guys would like an idea of how you could accomplish multiple extruders. This idea limits the print area by a bit and makes the inverse kinematics much harder. If that isn't a deterent, you just have to print a few pieces and reconfigure your Simpson. Providing inverse kinematics for variants like these will be something that I will try to put in my software so that the end user can drastically modify Simpson but not have to be a math professor. (or a nerdy computer science teacher like me)
