I think i figured out a way to connect the MMU2S with what i have. The TFT35 v3.0 has dual modes. It can be a touchscreen and connect via the tft connection on the mainboard but it can also be a lcd12864 and connect to the exp1 and exp2 connectors on the mainboard. I think if I wire this in and use this mode for the screen I can use the tft connection on the mainboard and get that MMU2S up and running finally. So I bought some ribbon and some ends and made some cables..

I am so excited to finally get to use the MMU2S. I have had it for so long now. Anyways, hopefully I will be posting up a multi material print soon. Making my own ribbon was the way to go. Nothing fits like cut to length..
