Temp Sensor Bed Error -- UM2

[dwardio 4]

Just ran into this while prepping for the local maker faire... Started new print job, but when the bed raised, it stopped early and presented me with the dreaded temp sensor bed error.

Powered down for 10 minutes then restarted. Everything seemed ok-- manually heating the bed worked fine and starting the print job began fine. Wasn't till the end of the print when I noticed anything wrong... The bed didn't lower, nor did the extruder home. The bed stayed at PLA temp and the control wheel was inoperative.

Manually adjusting the bed temp was useless-- remained at 50c regardless of the dialed-in setting. Only option was to power down the brick. Made Sure the latest FW was installed on UM2.°°

Tried to submit official support ticket, but the system wouldn't take my order number.

Planned to check connections, wires, and connectors, but saw warning about not doing ao until contacting support.

How stuck am I?
