Make sure the head is moved up after the last printed bit, so it does not hit other objects.
Version 13.11
Add multiple "total filament" stats on export. Split the support into different islands, making less moves between islands.
Only retract always if there are more then 1 islands, to prevent retraction on layer swaps.
Retract before moving up after finishing the print.
Add ooze-shield and fix the len bug in the ascii stl reader.
