Welcome to the SeeMeCNC Community

As I was working on my first print after FINALLY assembling my Rostock MAX, my heat bed just stopped working. Obviously I was displeased, but after contemplation I decided that fixing it is better than rage smashing this fine machine! Therefore dear forum users, I ask for your help!

My power cables for the heated bed must have touched or something, because now Heat-2 Bed now has a somewhat cancerous looking blob melted into the side of it ... Not a pretty sight, I assure you.

My question is this, can I power the heat bed from heat-1, which is currently unused? If so, how can I get repetier/arduino to recognize that change and function properly again?

Thanks for any assistance you guys (and gals) can provide!

can you include a picture?

In the attached picture, you get a pretty good view of the culprit area...

Looks like you had a poor enough connection in that one terminal that the resistance created enough heat to melt the connector until it failed entirely. Likely fixable by someone who can wield a soldering iron and has a spare connector pair.

Could you elaborate on that? I don't know how I can solder anything into that melted blob...

I meant removing the melted connector from the board (I think that's actually a strip of 5 two-screw terminals, not one strip of 10, but I don't actually have that board to look at), as it's ruined...you'd unsolder it from the other side of the board. The fact you asked the question suggests it may be a bit outside of your skill set. Maybe some practice removing some components from junk electronics would be a good first step if you're going to try that.
