Yes. A 4.7k resistor
Ok, that one was a bit outdated. I just updated it, it could have contained a bug in the bed temperature (There was a bug caused by one of my updates)
I tested the bed heating today, and it works in the version you can build now.
At least no error anymore but we still measure a wrong temperature(357.3C). Is it possible that our board revision 1.5.3 is no longer supported?
1.5.3? I've never seen one of those, but I think it should work, the firmware should support the whole 1.5.x range. But the lowest I've tested is 1.5.4 but there can always be a bug somewhere in the code. I currently do not have the facilities to test themistor settings.
We know the Arduino works with the AD595 amplifier and a TC, as used in the UM hot end. Is there any reason other than cost not to use an AD595 and K-type TC for heated bed control?

did you solder the resistor to the board to allow the thermistor to be read?
