Tool 0 was not driven heater not high enought



  • hello,
    so i fight with this problem "Tool 0 was not driven because its heater temperatures were not high enough or it has a heater fault"

    When i start print (test no filament) bed and hotend temp rise to set value in S3D but when printer start to move i have this error message and extruder not work - when i use M302 - cold extrusion everything is working good 😕 ??

    What i not see (i use low temp for test 40C bed and hotend)

    The firmware is doing exactly what it is supposed to do. If you tried to print with the hot end at 40 degC, all that would happen is that the extruder motor would stall or it would grind the filament away but in either case, nothing would come out of the nozzle. So the firmware prevents that from happening and gives you a message telling you why.
    As you've discovered, M302 will allow cold extrusion so if you add that to the start of your gcode file, it will allow you to test it (but don't try it with any filament loaded).



  • I am testing printer so i dont have load filament.
    From what temp it allow me to test all ??

    Unless you use M302 to enable cold extrusion, AFAIR the minimum temperature for extrusion is 160C.

    As always dc42 you the best !
