Burned Heated Bed Connector in Ultimaker 3D printers Posted November 24, 2016 · Edited November 24, 2016 by Guest If your in the US FBRC8 has the bed parts. I had the same exact thing happen to me and they sent me a new bed and connectors. They told me UM had problems with this so they changed the connection type to push pins. This is what my connector looked like when I hit it with the FLIR. I was noticing a smell for a few weeks that smelt like wet dog and couldnt find the source until I started seeing smoke.
