Z Hop only on top layers

[Psyonic 1]

Hey all,

Does anyone know if Cura can produce a "Z Hop" before a travel move ONLY on TOP layers??

 

Z Hops are not needed everywhere with good temperature and retraction settings but would be very useful if only used on TOP layers, due to the nozzle leaving that horrible melted line on the beautiful, fresh top layer.

If this is not currently available, perhaps this could be included in future releases??

try changing combing mode to "not in skin" and see if you like the results better.  By default it doesn't retract on internal top layer moves and so you get these melted lines.

Hi gr5

I tried your suggestion and the lines are still there but are almost invisible, so that's good, but it has created all these start or stop points that are much worse than before. Do you know what makes them or better still, how to reduce them?

The first picture is with combing mode set to all, the second is with not in skin.

 

Thanks
