I also can´t slice. I tried clicking on the Slicer and I get the following error:
I could not find the generated G-code file.
-the slicer had an error an didn´t finish slicing. Check log out put.
-the slicer stores the file with an unexpected filename.

Expected Filename and Location
C:\Users\Chema\AppData\Roaming\easyprint\work\composition.gcode

At first time y could slice without problem more than four files but now is impossible

Could you give me more detail via taking some photos?Any tips on issues or error code?
