For what it's worth to future google searchers, I replaced the Love board and the Nextruder cable with no luck. Got a new xBuddy board and that seemed to do the trick - not sure what was wrong but something seems to have happened to the board itself. Couldn't see anything visually wrong with it.

I am receiving a 20615 error upon startup of my new printer (self assembled from kit version), I have double checked all my wiring and connections including re-assembling the nextruder with no luck on fixing the issue.  I did reach out to Prusa's help but have not heard back from them yet, posting here also to see if community can help.  I do not believe it is a issue with a connection per the GUI prompt, so not sure if this is a faulty part or something I'm not considering to check.  Any help/advice is appreciated, there is not a support page on this error as far as I can find (URL in GUI just takes me to Prusa home page).
