Weird lines sticking out in Cura that also appear on the print

· Weird lines sticking out in Cura that also appear on the print
Wow. Pretty strange. I have a lot to say about this. Well first practical advice:
1) Look at the part in "xray view" (as opposed to slice view or normal view). If there are any red areas then those could be the problem - try to fix in cad settings or play with the "fix horrible" settings.
2) Try the latest slicer that came out a few days ago. It's a completely new rewrite. If this is a bug in cura you have to first verify that the bug exists in the latest cura before the programmer will look at it for you.
Now for theories...
1) Make sure all the "fix horrible" boxes are unchecked - they can do weird things.
2) it looks like these lines that stick out start at the right edge of the finger and end where the part goes in more. I'm not sure what the distance is that the hand shape comes "out" but...
Some models - particularly "sculpted" models - animals, people, gnomes have way too many polygons that are smaller than the nozzle diameter so Cura has a feature where it discards a few of the "lines". Let me back up to do a slice cura intersects a horizontal plane with all the triangles in the STL file. Those triangles are unordered so Cura has to figure out which go with which after it does the slice - it takes all those lines and tries to connect them. During this step some of the lines are too short and it gets rid of them - I'm thinking this step needs to get rid of fewer lines - it would explain what you see if is was doing counter clockwise pass on those "bad" layers.

One more thing to try - rotate the part by 2 or 3 degrees to see if that goes away. You can rotate by less than 15 degrees if you hold down some key - maybe shift key - I forget (shift/ctrl/alt - one of those).

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
