Switch from E0 thermistor to E1



  • Hey,

    I'm having a problem with the first thermistor connection, once the hotend reaches 200+ degrees a slight wiggle to the connection on the board will cause my temp reading to go crazy.

    I've tried with different thermistors, making sure things weren't pinched, etc. It's pretty consistently the connector on the board. Solder all appears fine as well.

    I'm wondering if I can switch the printer to use the second thermistor port instead. When I try to set it the thermistor reads as an open circuit and I get 2000 degrees. My code is:

    M305 P0 T100000 B4092 R2200                             ; set thermistor + ADC parameters for heater 0
    M143 H0 S150                                            ; set temperature limit for heater 0 to 150C
    M305 P2 T100000 B4092 R2200                             ; set thermistor + ADC parameters for heater 1
    M143 H2 S275                                            ; set temperature limit for heater 1 to 275C
    

    Thanks!



  • I fixed it, feeling kind of silly for missing it.

    For anyone else that comes across it, I was missing updating my M563 command to also use H2
