I downloaded the newest version on Windows 10. Had many issues. Went back to version 3.3.1 and started having the print not finishing completely problem. Ran great on Windows 8.1. I'm wondering if if it's a Windows 10 compatibility issue.
I upgraded to windows 10 and have had more than one issue with Cura. Can't get it to load the gcode to the micro SD being the most troublesome one.
