Unnecessary geometry in my print (issue/problem)

Dear community,


I recently got a MakerBot Replicator 2x and in most of my prints I get this strange L-formed geometry, totally separated from my actual print.
After every printed layer of the actual object, the nozzle goes and makes a layer on the L-geometry. It often doesn't stick well to the plate and ends up ruining my print. Also it is a major material loss...


Do you have any ideas what that is and how can I fix it?

Your printer is okay. Those are called wiper walls or purge walls. It helps keep the nozzle clean while printing with multiple colors, and maybe retain some heat to help minimize warping.

The feature can be turned off. In your print settings look for Multi-material Printing and go to the Purge Wall settings and uncheck the Purge Walls box. That should do it.
