Update and success: I switched the two thermistors over where they wire in to the Melzi and got the same readings, only reversed. Spoke to Tech Support and they suggested that the board might have Huxley firmware rather than Mendel, as the Huxley uses two 100k thermistors rather than one 10k one and one 100k one (which would explain the readings being swapped in that last test).

Cheers for the replies, I'll have a look at it again tonight. Going to check that firmware first, as it looks like it could be some sort of calibration issue, then will check the board itself. Will let you know how I get on.by Trappisto - General Mendel Topics
Hi all, Done a few searches for this already but can't see the specific issue (and have tried some general advice from what I've found). I'm just commissioning a mono mendel which I bought about this time last year (long build...), and have an incorrect reading from the bed thermistor.
