Thermosister on E0 is working fine, E1does not (New Board)



  • I have a hotend on E0 and bed on E1. I have a second board/printer that is working fine with the same config and setup. I swapped the thermosisters to make sure they work and they are fine. Just not on E0. Please see config below for the thermosisters. Any thoughts?

    Temp is showing normal on E0, 2000 on E1.

    M305 P0 T100000 B4388 R4700 H0 L0 ; Put your own H and/or L values here to set the bed thermistor ADC correction
    M305 P1 T100000 B3950 R4700 H0 L0 ; Put your own H and/or L values here to set the first nozzle thermistor ADC correction



  • A temp of 2000 usually means nothing is hooked up to it.

    1. Check all connections (and wire crimps).

    2. Make sure you have a thermistor and not a thermocouple if they are from E3D. They look the same except for the length of wire.

    3. When all else fails swap the bed and hot end thermistor connections and see if the temps follow along. If they do then its wiring or a bad thermistor.



  • Yeah, that was the odd part, E0 had the working thermosister, it works fine. I plug in E1, it doesn't work. I flipped them to test the thermosister and E0 still worked, the one that worked on E0 does not work on E1. I think that was what made think it was my config. Both thermosisters seem to be working on E0, not E1.

    The M305 P0 command is for the bed thermistor, and M305 P1 is for the E0 thermistor. To use the E1 thermistor, you need a M305 P2 line too.
