Downloaded the newest version and after many, many attempts to slice I get the prepare button to show up without highlighting it. Push it then the error unable to slice shows up. I have uninstalled, reinstalled, and even run it as the administrator. Even loaded up the profile models for your printer ulitmaker whatever the number shows. It will not slice. I can get the 15.043 version to work. But what ever this ultimaker slicer is compared to the original cura slicer that came with the creality printer, I can not get your program to work as it is intended.
There sure doesn't seem to be much on the internet addressing this issue.
