Ultimaker 3 extended dual extr mix up

Recommended Posts

Posted · Ultimaker 3 extended dual extr mix up

When I am printing dual filament the printer in the middle of the print mixes up things. For instance haf of the print is mirrored.

This is clear on the attached picture it started with the little waste rondo it started left front and now it is trying to finish on the other side.


Anyone has an idea what it could be or is it a fault in the printer?

Wow this is weird. Never seen it before. What does the Cura layer preview say? Do you see the wrong extrusion mid print there too?

no there all seems to be fine and actually the rondo was projected in the right back corner where it tries to print now. At least my little boy thinks it is funny, he is seven so you have to give him that.

It is only happening when i use dual extrusion with one solid everything is perfect. I have a lighhouse where the rondo was ok but one door is split in 3 and thus in three different places.

      Through this post I would like to further explain what we are doing, and what you could be doing. 
      Our efforts consist of 2 layers. First; connect medical institutions and hospitals to (local) 3D Printing hubs to help them print parts of which a 3D model already exists. And second, contribute to design the necessary part and then have it printed via a (local) 3D printing hub. Experts are available from within Ultimaker and from within our network of 3D printing experts.
