Topic: Printer displays incorrect temperature
Hey, help me please. I have problems with incorrect temperature, Arduino Mega 2560, Ramps 1.4 + Mendel v1
- When the only extruder is hot, i have the high temperature of both the EXTRUDER and HEATED BED in the same time.
- When the only bed is hot, the temperature of EXTRUDER and HEATED BED freezed.
- When i switch on my printer and connect the sensors, i have the temperature of EXTRUDER = HEATED BED
I've used this scheme to build my printer up: http://i.imgur.com/kBUFKft.jpg
Resistance:
temp. sensor of EXTRUDER = 96 кОhm
temp. sensor of HEATED BED = 101 кОhm

And this is an example of my combinations:
