I’m currently building a new 3D printer with dual nozzle, but the firmware on the board sends the wrong temperature back to the raspberry. The structure consists of 2 hotends, each with an amplifier and a PT100.
If I measure manually, I get 1.2V, according to my custom sensor that should be 20 ° C. The firmware sends back 200 ° C. Since both sensors behave in the same way, I no longer know what to do.
Board: BIGTREETECH-SKR-PRO-V1.2
