Hi guys, I seem to be having a problem with my heated bed. The bed seems to be heating slower than normal, but was able to maintain temp when manually heated. However once the hotend starts to heat a well the beds temp suddenly plummets, and eventually I get a Thermal Runaway notice at the printer stops.

When I had this problem, the power wires in the cable chain connected to the bed were broken. When the bed was in one position it would heat just fine, but when the bed moved, the wires would make/break contact and would throw up a thermal failure. I'd start there.
