My R2 heated bed has the Pogo Pins problem and is loosing connection like some others on here. I've attached some pictures to show it, the spring out of one of them actually looks burn't. I've emailed support, and still waiting on a reply. To disable the heated bed and continue printing: Go into your Settings on the web interface, then Printer Profiles, click the edit icon. Click on the Print Bed and Build Volume Tab, and uncheck heated bed. Click Confirm Button then click Save Button on the next screen. Its pretty straight forward, but I've attached some images to make it easier to understand.
