Hello, I have done a little bit if research but can't seem to find the answer I need.
In short I would like to know if this is normal, if it is I know I need to research firmware, if not I need to figure out wiring/if I have an issue with my board.
When I pull thermistor 0 from my board it reads 100k ohms.
When I replace in the board it reads 3mohms ( or was it 300m ohms).
I'm sure I'm reading something in the board, but is this normal?
Firmware is setup for standard e3d therm, t100000 b4725
C I tried values from configuration of e3d and Honeywell.
In DWC it actually shows error
@ameigh710 If your thermistor is reading 100k ohms at room temperature (about 25C) that's about right. You can't really read it when connected to the Duet, as you'll read the extra circuitry in the Duet, so a different reading is normal. You will get an error if you disconnect the thermistor while the Duet is on. With the thermistor disconnected, you should get a reading of -273C, and with the thermistor pins shorted (use a jumper or attach a wire, rather than poking a screwdriver in there) it will read 2000C.
Do you know what the thermistor make and model actually is? Depending on the thermistor, you may not need a C parameter.
If you're still getting an error, please post your config.g, and response to M115 to show firmware version and Duet hardware. Most likely it's a configuration error.
