My temperature readings are always wrong- room temp is 30C. My printer ends up being to cold to extrude properly. I think that because my Melzi electronics uses 10k pull up, as opposed to 4.7k, the readings are incorrect. I have attempted to produce a table online but the readings are -26C.
I am using Marlin with Getech Melzi and a 100k thermistor with 3950B 1%.
