Extruder temperature startup problem

  • I have a problem that occurs randomly at startup as everything goes smoothly at printer level but does not start the extruder ignition without giving any kind of alarm and stop printing automatically. What can this anomaly cause?
    I attach my configuration file:

    ; Configuration file for Duet Ethernet (firmware version 1.17)

    Best regards

  • You need at least a T0 at the end of config.g,.

  • administrators

    A T0 at the end of config.g will probably fix the issue for the first print you do, but may not fix it for subsequent prints. So a T0 command in the slicer start gcode is normally better. However, recent firmware versions select the tool automatically when a set-temperature-and-wait command is processed. So if you are running firmware 1.17 or earlier, upgrading to a later version may solve it.
