Thanks. I have an open ticket. I was hoping to find something obvious. I took the 4 screws out of the board and I can see the two wires are fused together (overheated?). I had to pry them apart. I also see a loose wire that I don't know where it goes. I did not see this before I took the board off. It is a whtie/blue connection. Here is a pic. http://www.flickr.com/photos/119499626@N06/12953765994/

I found the green block where 2 of the heated bed wires attach to the board. One appears to be a dark brown from possible heat.

I removed the heated bed and did not see anything out of place. There are 4 wires plugged directly into a block on the heated bed. The wires appear to be in place and solid. On the other end I'm not quite sure where the heated bed plugs in. I removed the larger of the two plates on the bottom of the machine. I found the board that says 'Ultimaker'. There is another cover on the bottom that is smaller below the ulti-controller where the wire harness from the heated bed appears to terminate. However, I cannot get this plate off to inspect the electronics. I'm not quite sure of how this comes apart and I don't want to make it worse. The bearing block is definitely cracked down the middle and all the belts feel very tight.

I have a 2 month old UM2 that has been going downhill slowly. I was at the end of a 4 hour print when one of the belts slipped and the hot end began spilling PLA over the side of the build plate and smashing into the side. I aborted the print and scraped up the PLA. (I am not using any adhesive). When I went to print again, the heated build plate would not heat up. Should I assume it's fried or is there a connection I can check somewhere? I took the electronics cover off, but none of the wires were detached. Neither were any of the wires at the rear of the platform detached. Now I have no heated bed and a cracked plastic bearing block. I submitted a 'support' ticket but have not heard back anything yet. Does anyone have any ideas? I would even settle for installing the parts myself if I knew where to find them.

I found on the new firmware in 14.01 if abort a print, then go to advanced -> move material, the extruder will not move and no beeps are hear when I rotate the wheel. Neither does the filament advance. Resetting the printer fixes this.

I found that adding a Brim in Cura works well for PLA to stick. I've quit using the gluestick for PLA, all it was doing was clogging up the nozzle. I still use it for ABS however. I found I had to up my PLA temp as well to compensate for the colder temps in my work area. 10 degrees did it for me. I would suggest focusing on your bed level if the PLA will not stick.
