Dual Extruder for UMO+ (Other posts have not helped)

[nerdwarrior 19]

Hello community,

I just got my UMO+, my first 3D printer, and I like that I can hack it all I want. However, I'm unbelievably noob: the most I've ever done in electronics is turning an LED on and off in relation to a temperature sensor's input value. That said, I still want to be able to upgrade my printer to dual extruders for dissolvable supports (I've spent hours reading through other threads and it seems like I won't have to hack extra temp sensors and whatnot onto the board), so can someone please show me some place that has step-by-step instructions fit for a 3 year old? Things like "just buy another pt-100" make no sense to me.

Also, I want to keep modifications at a minimum, so I (preferably) need sth to make the UMO dual extruder kit work or sth similar.

Thanks!

Am I correct that all I have to do is buy a new hotend+extruder assembly, set it up in the same way, but put the extruder on the other side and put the hotend through the other hole? Then the new temp sensor goes into the temp 2 terminal, the heater goes into heater 2, and the extruder motor goes into E2, right? It's seems so easy now that I've finished assembling, and it seems like it was built for dual extruders!

After I do that, all I need to do is change the firmware, right?

To the noobs like me: don't freak out, finish assembling the whole thing, and all the pieces will come together!
