I know there is an already very detail filled thread on the forum. But I've run into a problem and not even scouring through the thread helped. I just got through putting my hot end together but I am still unsure about the wiring, my main concern is wiring the heater cartridge back to the ramps board. The one that came with my E3D hotend has two prongs on the end. I thought I am supposed to plug it into D9 on the ramps board but I'm still unsure if that is correct. Another issue I'm also having is that I cannot get my hot end to stay using the newly printed quick release. It just kinda hangs there and is not stable. I tried sanding it down to make room but it's still not on there tight enough, is there something I'm doing wrong or is there a better option to keep my hot end firmly in place. I would appreciate any help to solve this as I am at my wits end trying to get everything set up.
