Hello, I was assembling my UMO+, and I realized that I had screwed the hot end isolator tube into the wrong side of the peek, and now I can't unscrew it (I tried wrenches, bare hands, gloves, tried until i got bloody fingers). Does anybody have any tips for this? It's kinda sad, cuz if I can't fix it, I'm kinda screwed (and my local reseller doesn't sell a UMO+ hotend pack). Thanks in advance!

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!
