bed temp showing for both bed and hot end temperature values



  • Just getting started with 3D printing and was given a duet v0.6 board. Trying to setup a kossel mini printer and have movements functioning, however, the temperature of the hotend is showing the temperature of the bed. AKA both the bed and hot end temperatures are showing the same value. Unplug the bed thermistor and they both go to 2000C. Swap the hotend thermistor into the bed connection and they both show the hotend temperature values.

    What do I need to change to get the hot end temperature reading from the correct thermistor? I know the thermistor works from swapping them. What gives?



  • I was able to go to the settings -> tools tab -> and then define a "new" tool with the associated heaters as "1" and associated drives "1".

    This finally made the "tool" assigned to heater 1 instead of heater 0. What code am i messed up on?

    ; Heaters
    M305 P0 T100000 B4138 C0 R1000 ; Set thermistor + ADC parameters for heater 0.
    M143 H0 S120 ; Set temperature limit for heater 0 to 120C
    M305 P1 T100000 B4138 C0 R1000 ; Set thermistor + ADC parameters for heater 1.
    M143 H1 S280 ; Set temperature limit for heater 1 to 280C

    ; Fans
    M106 P0 S1 I0 F500 H-1 ; Set fan 0 value, PWM signal inversion and frequency. Thermostatic control is turned off

    ; Tools
    M563 P1 D H ; Define tool 1
    G10 P1 X0 Y0 Z0 ; Set tool 1 axis offsets
    G10 P1 R0 S0 ; Set initial tool 1 active and standby temperatures to 0C

    ; Automatic saving after power loss is not enabled

    ; Custom settings are not configured

    ; Miscellaneous
    T1 ; Select first tool



  • How did you get your config file set? Did you use the configurator?

    @jarvxd said in bed temp showing for both bed and hot end temperature values:

    M563 P1 D H ; Define tool 1

    That line is equivalent to M563 P1 D0 H0. Heater 0 is the bed heater. Also, it's more usual to define your first tool as Tool 0, because that is what most slicers expect. So try this:

    M563 P0 D0 H1
