Cura start gcode settings - Not


Recommended Posts

Posted · Cura start gcode settings - Not


I have made a custom gcode at start on the printer settings page. But upon reviewing the generated gcode after slicing, there seems to be additional lines of gcode added to it. Please see the attachments. Is there a way to edit? Or this is permanent in Cura? I am using version 4.8.0.

    I am having the exact same problem.  It is a problem because T0 is selected.  For a Duet board, the extruder will not move filament unless the hot end is above 100C(I think).  Here is what happens:


    Machine cold:

    T0 is selected, triggering the tool change macro that advances the filament 100mm past the Y adapter.

    filament advance command aborts because temperature too low.

    Filament is now 100mm before hot end, and brim of print is not completely printed.


    Machine hot:

    T0 is selected, triggering the tool change macro that advances the filament 100mm past the Y adapter.

    filament advance command is successful because hot end is above 100C because of previous print.

    Filament is correctly positioned and brim prints correctly.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
