Had a successful print running last night, new print with the same profile but different part today yields this problem. https://s3-eu-west-1.amazonaws.com/ws-share/Printer_crash.tiff A few minutes into a print the printer just gives up heating the bed (note the target temp doesn't change, except for the manual change to 81C I made to try and kick it back into heating again). It's done it on 3 consecutive attempts (the 3rd after a power down reset). You might think it's a connection problem or fet driver overloading on the board etc...but when not printing the printer will happily keep the board heated. Eventually it crashes (similar error on the printer screen saying heating failed and reset required) Running RC7, no recent changes have been made for about the last 30 successful prints.
