Hi. I have a problem with thermistor reading issue, and searched over the internet, and didnt found much useful info, so may be if you have a time, you can help me. I made a RAMPS-FD v2 rev B myself, and all works great, but 100k thermistor shows about 100-110 degree celsius all the time. When i try to hot it, i see some rising temp reading, but only for 120 degrees, when real temp is about 300-400 degrees. When i unplug RAMPS from DUE, temp reading rise to 230 celsius. May be such case nown to you, and yo can give me some advise?
Are you sure it is not a firmware problem?
I checked this several times, using different firmwares. For example i tried latest Repitier for Ramps-FD (with DUE) and for Ramps 1.4 (with Mega) with the same settings, and on mega thermistor readings were correct. And i have a lack of expirience to correctly debug this issue.
There appear to be two problems:
