Starting each layer with the same Extruder - Cura - Dual Extrusion - UM3E


Recommended Posts

Posted (edited) · Starting each layer with the same Extruder - Cura - Dual Extrusion - UM3E

Hello Guys,


I didnt think this would cause me so much trouble, but I need to start each layer with the same Extruder. Right now, the extruders take turns every layer, I guess to minimize extruder switches.

Im printing with an Original Ultimaker 3 Extended with the most recent Cura 4.8

The print quality is much better, when the black material is printed first(right picture), and after that the white material. 

White first,Black second   (Bad)                               Black first, white second(Better)

In my case this impacts the functionality of my part as well(conductive) so there is a good reason for being able to set the same extruder for every layer.


Does anybody know of a way or workaround to do that? I guess there is a way to post process the G-Code to reposition the Code between every T0/T1 Snippet with a python script?


Thanks for any thoughts.

      • 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
