Hi @smartavionics, I was trying to get Cura to print 1 line thin wall without double backing, and found this thread. Tried out your cura master Cura-mb-master-win64-20191125, works great, thanks! However the newer version after that, up till the most recent Cura-mb-master-win64-20191228 failed to slice the attached object, stuck at the progress bar, please have a look.
Also the print settings UI is pretty glitchy, but that's probably out of your control, see attached.
