MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
I have never used Cura and am still fairly new to 3D-printing (got my printer four days ago). I might need to look into it, but there should be a reason for these things to happen. Afaik, it was filed as an issue on github once, but resolved. Also another person had this issue already (see Jan 25, 2019) in yet another slicer. Does anyone know of involved settings which can be tuned to avoid these bridges to be created?
Or maybe I'll just wait another "24 hours" until the gen3 OEM duct get's released :) Gonna print the bed supports in the meantime.
