Ultimaker Cura isn't slicing

[Zoe 0]

I'm trying to print 50 of a small part and when I only have one it slices perfectly fine, but when I try and slice all 50, it just doesn't slice.

it just stop here and doesn't slice. I've had no problem slicing with larger prints than this

I'm guessing it's a memory problem.  You might be able to fix your issue by reducing the number of triangles in your model.  Is this your own model?  What CAD did you use?  Usually when you export to STL (or other mesh format) you can choose the resolution - try making that low.  Also try closing other apps like chrome.  Here's one quick way to lower the number of polygons:

Anyway it could be something else.  Please post the log file (go to "help" menu in cura).  The log file stores a long history of errors so even though you may have to kill and restart cura it will be helpful.  Maybe tell us what time the error occurred so we don't have to sift through days of non-failures.

 

Also please post a project file.  So we can repeat the crash.  Do "file" "save project" and post that file.  It will contain you model and settings and printer settings and which profile you used and filament and the position of every one of your models and so on.
