well keep an eye on that connector. it can get hot if you dont have a perfect connection. most of the time when there is a little meltdown on that and only the one side is replaced it can happen again. sometimes you need to solder a new one to the rambo. not to get you worried just keep an eye on it to see how hot its getting. you odnt want to do it again. look on thingiverse as well. i have an electronics box i designed on there for the m2 that has a lock in the back to keep the connector from coming loose. here is the link.
