Received the new PT100 sensor and amplifier board from e3d and have pretty much the same results. 1.119 volts with the signal pin not plugged in and 1.278 volts with it plugged into temp0 input pin. The power for the amplifier is being taken from the modified Y max input (changed connector to get ...

I could see the sensor being wrong if I didn't get the right voltage value with the amplifier disconnected. It's the change in voltage when it is connected that is the problem. E3D is sending me a new sensor and amplifier to see if that is the issue and I will update this post when I try this out.

I am having trouble with my E3D PT100 temperature sensor when it is connected to my GT2560 board. If I disconnect the amplifier from the GT2560 I get exactly what I should, 1.211 volts. When I connect the temperature sensor to the GT2560 it changes to 1.289 volts. This throws my temperature off by ...
