Hi
So I've upgrade from 4.10 to 4.13.1 and everything is still printing good, just V5 it the problem.
I've added the gcode files from 4.13.1 and 5.1 and STL file.
Also images of the cube printed using the 4.13.1 GCode looking ok, and the 5.1 GCode starts off ok and then ends badly.
Other images of the model I wanted to printed using the 5.1 GCode, which does the raft ok and the first few layers but then goes wrong, so I stopped the print. The other image shows the model currently printing on 4.13.1 GCode and looking good, you can see the 20% fill ok, and the top part of the model filled.
I have compared the setting in both versions of Cura and they look the same. I couldn't see a way of exporting the settings otherwise I would of uploaded them here as well. Could only see backing up to my Cura account, which I've done (in case a Cura Staff member wants to look)
