I'm new to 3D printing, Cura, and I DO NOT have an Ultimaker printer, so I'm in at the bottom end of the learning curve to start with. To make this worse while I have successfully printed using v14.07 and 15.04, I wanted the "luxury" of profile management and because I'm using 32 bit Windows I'm limited to Cura 2.3.1. Some of you may see where this is headed, lol. There appear to be differences in the Z axis starting points (a guess) because 2.3.1 prints (that print OK in 14.07 and 15.04) start printing with the nozzle too high from the bed. Now I'm reading that 3mf files in 2.3.1 may not load correctly but this has been fixed in 2.4 which only runs on 64 bit Windows. I'm reluctant to try 2.3.1 again since I have no idea what other bugs it has. Bottom line: Since Cura 2.3.1 is the highest version that runs on Windows 32 bit machines my suggestion is to either fix the serious bugs in 2.3.1 or start an FAQ/Bug topic sticky for version 2.3.1
