works fine for me, thanks! |

Tahnk you. Unfortunately I can not test it but does it allow you to set the distance of the draftshield from the object? I might need a wide skirt with a closely draftshield closely placed to the object (e.g.for PA or PC). |

Hi there this PR implements a draft shield the exact same way as prusa slicer. Have a look there to confirm ;) |

Yes but we are better than PrusaSlic3r.. :)

hey @SoftFever not sure what you mean? what am I missing .......? below is from the latest pr build
|
Hmm, I guess you have dev mode enabled in your application settings that's why you can see the draft shield option. |
|
Duh I’m stupid haha! I’ll fix it |
|
Done, updated to comAdvanced ;) |

hehehe, thanks. |
Description
For certain use cases it may be useful to implement a parameter that controls the minimum amount of filament in mm that is purged out at the skirt. For example, when no purge line is used a minimum skirt length can be employed to ensure the nozzle is primed.
In addition, certain use cases benefit from having the option to easily enable a draft shield - i.e. a skirt as tall as the object itself. This is useful when printing warp prone material in an open frame printer.
Finally split the adhesion options into two groups - one for skirt and one for brim, to clean up the UI
This is a localised change as the code was already present in the code base, just deactivated as the option was not exported in the UI.

Tests
Validated with 0 minimum skirt length -> number of loops is respected
Validated with multi material selection -> first tool is used to print the skirt as expected
Validated draft shield functioning
Limitations
Due to the way skirts are constructed in the slicer, having a greater than 1 layer skirt height or the draft shield active will result in the minimum extrusion amount being extruded for each layer where the skirt is printed. This may or may not be desirable. If not desirable, the user should set the skirt height to 1 layer.
