Mystery Tower

[Jimwn18 0]

Does anyone know why this tower in the bottom right corner is showing up in Cura? It is not in my Solidworks file. It doesn't show up in the "Solid" view mode, only in the "Layers" view mode. I don't want it and I can't select it. It gets printed from Print Core AA.

This is the Prime Tower which is used to make sure your extruder is primed before starting on the print. It's just a place for the machine to deposit some material so you don't get gaps in your print. Cura generates it when using dual extrusion. You'll notice that it disappears if you print supports using the same material as the model.

You can override this setting by going to Custom > Dual Extrusion > Enable Prime Tower

It is called a "prime tower". It is printed there to make sure each extruder is "primed" (topped up with material) before starting its part of each layer. You can turn it off if you wish in the custom settings

Better upgrade to Cura 2.4 or 2.5 beta. Prime tower has been disabled for all print profiles because oozing was solved differently.
