Cura Setting

rphillips1991

I have the A5 Printer, and am having a problem with slicing 

I have been having great success with models sliced in Cura 15.04.6

I have the new version of Cura set up (i thought), but the first layer will always fail, and so my prints wont complete. 

what i cant get my head around is why the old version will let me print near perfectly.

Welcome @rphillips1991 !

Here's a clue:

;Filament used: 0.27m 0.0g

;Filament used: 0.101763m

Check that your slicer has filament diameter 1.75mm selected, both in the machine settings, and in the material manager settings.

This is a bug with 3.6 that has been INCREDIBLY frustrating for many people. You're not alone.
