Temperature is showing about 680 °C at room temperature. When I make it "hotter" by holding my thumb and index finger on it, the temperature does increase. So it is responding to temperature changes.
I'm trying to add some thermistors to my MKS GEN L v1.0 board:
I'm using the
A11 pin and
GND in the picture above.
The thermistor works correctly when plugged into the
HE1 temperature pin. So the thermistor is fine hardware-wise.
The thermistor is set to be the "Chamber" thermistor in Marlin 1.1.x. This just means it is supposed to record the temperature of the enclosure. I don't know if there is some kind of volatility issue with the chamber constant in Marlin.
The thermistor has the same settings in Marlin for both
HE1 and the chamber one. They are both set to "thermistor 11" for the 3950 type of thermistor. So the most visible setting implies they should be treated the same firmware-wise.
I've also tried the other extra Analog pins in the AUX-2 port.
What could be the issue here?
If these are the only available analog pins, how can I add more thermistors to my set-up so that they're available in Marlin?
Is there any way I can use the AUX-1 port? It doesn't seem to be an analog pin like in the photo for this particular version of RAMPS. I tried pin
A3 but it didn't work.
