Heater 1 fault (T0) - 2000°C



  • Hi,
    yesterday evening i have switched on the duet wifi for the first time connected to my new D-Bot core xy.
    The wifi is good connected but i see this "Heater 1 fault (T0)" with 2000°C in the heater section from the web interface:


    The thermistor is connected in T1 because i read somewhere in the wiki is preferable to have the bed connected to T0 (i don't have it yet but it is a future update)
    i don't sure on it's type because it came with a e3d clone, i think it is a 100k ntc 3950.

    and this is my config.g:

    ; CoreXY sample config file for dc42 Duet firmware by Haga. Please use with care. Some of the settings needs to be changed to work with your printer. Read the duetWiki!

    Do you see some problem? i can't find any issue.
    Thank you in advance


  • My fault, I've connected the heater and thermistor to E1 instead of E0
