Cura generates not needed part when using support


Recommended Posts

Posted · Cura generates not needed part when using support

When using support on a dual extrusion (S3), Cura generates a second part:

I only need support in the hole at the top of the red tower. The blue tower is generated by cura when using the second extruder for support. Red tower is printed by extruder 1, Blue support by extruder 2. When using only extruder 1 for printing AND support, no second tower is generated. How comes?

    Hi,

    the blue tower is called prime tower and can be activated / deactivated in the "dual extrusion" setting.

    It's main duty is to prime and wipe the inactive nozzle when switching, so no unwanted material is contaminating your print (same as an ooze shield).

    I always use the prime tower when printing dual, others never use it, so it's your choice.

    Regards

    Thank you very much - yes, that's it. Well, it uses a lot of material and normally I don't have have a problem with contamination, but good to know, just in case.

     

    PS: since there is a plethora of settings, I am sure I did miss over 50% even after reading the normal guides....
