I tested with stock firmware and compiled fimware as well.
both of them, temperature sensors not work.
just '-14' degree shown on the lcd screen.
please confirm whether this is known problem or not, or only my case.
Mine is fine. I am using 100k thermistor.
GeorgeFu mine is same type of thermistor. Maybe my board is out of order 🙁
From unboxing, it's not working.
You can try to compile the firmware using our AIO config example , and upload it .
GeorgeFu I did. I compiled latest version and uploaded using AIO conf. But not working 🙁
Will you take a picture of thermistor connecting ?
Is that a thermistor or a thermocouple ? My thermistor is like this
GeorgeFu I have several kinds of thermistor, and already tested with all kinds of my thermistors including NTC 100K bare wire end.
You can change the following define 1 to -1 in configuration.h file
#define TEMP_SENSOR_0 1
#define TEMP_SENSOR_BED 1
Then have a try
Then change the firmware as i said , compile and upload , to see if fix this
GeorgeFu do you mean... even if I use NTC 100K thermistor, should I set AD595 config in Configuration.h?
Just have a try , the look really like a thermocouple . Oh , have you try the connector next to it ?
GeorgeFu I'm using this thermistor on my five 3d printers with same marlin configuration. And I tested bed socket too.
What about refreshing the firmware ? Just use example config of AIO_II board .
GeorgeFu I tried everything I can do. I give up. anyhow I talked with Ms.Luo on facebook messanger and she promise she'll send a new board to me under warranty. so I totally give up this issue.
That's fine. It's an option.Look forward for hearing your new board running well.
GeorgeFu thx, I'll update the result here after testing new board's thermistors.
