UM2 Built Plate not heating up

[waitee 1]

Have been running my UM2 for since 2014 with the usual maintenance and not having major problem.

Today suddenly there was a bad burnt smell and my print was in a mess of tangle wire.

Going through the maintenance menu found Built plate heater not working.

Have to check tomorrow to see what is wrong.

 

Anyone face this problem before?

Found the problem - Burnt Built plate connector. Removed the burnt connector and soldered direct and it work.

Yikes, I guess one of the wires had worked loose and was shorting.

I had my wires come unsoldered from the buildplate itself. Difficult to solder because of so much metal, but it's been working for a couple of years since the repair.

 Yea it is because the connector is the spring loaded type and not screw on - before this happen was getting some very bad print with lifting from the built plate.
