I teach middle school design. Students are using Shapr3D to make models and exporting as .stl files for printing, mostly on a creality ender 3 V2.
On my main laptop (MacBook Pro running Monterey OS 12.2.1) and Cura 4.13.1 (but also on older versions), when I slice a model, the outer 3 layers don't print and though visible in "prepare", they are missing in "preview". This happens with support on or off, with multiple layer heights, and in different profiles.
Any ideas? This is having an impact on my professional productivity.
Thanks,
Mike
