Z Hop bug

[LibrePixels]

Hello,

I have problem with "Z Hop performed only at top and bottommost surfaces". I don't think this feature works the way it should. If you are using "Allow Filling Gaps using Single Extrusion Filling" Z hop is performed incorrectly on each layer.

Single extrusion filling enabled:



Single extrusion filling disabled:

Thank you!

To determine whether to trigger a Top Surface Z Hop is according to whether there's Gap Filling, Top surface Layer or Top surface ironing.
Bottommost surface Z hop only will be generated when the layer is 0 and there are solid fills or gap filling.
When Single Extrusion Gap Filling disabled, the top surfaces will only have regualr gap filling with no Top Surafece Z hop.

Thank you for your reply! The reason I'm addressing this setting is because when printing with PETG, stringing occurs at the Z hop. When the Z hop is triggered in the middle the model, it causes stringing issues. I only need to use Z hop to prevent scratching top layer of the model. So the solution is not to use "Single extrusion filling" at all. Is that right or am I missing something?

Single extrusion filling needs to be enabled.
