Is your feature request related to a problem?

Sometimes when printer fills internal solid infill with any pattern, it fills for example one corner then moves another corner to fill but it doesn't do z hop and scratches the surface. It may cause layer shift and/or scratch on a surface.

Which printers will be beneficial to this feature?

Would be cool to add otion to add z hops on a travel moves on solid infills.

I have the same issue, my opinion this is a bug with the gcode. Orca Silcer doesn't care for what ever setting i try to toggle on or off. (Z-Hop is enabled as 0.4) The issue is still there in OrcaSlicer_Windows_V2.2.0-dev_portable

File: https://github.com/AdamV3D/Dayspring/blob/main/Mounts/Dayspring%20Mount%2045%20v12.stl download the file and turn it as shown:

Example: The nozzle moves causing scratching on the infill surface, at layer 25

Photo from printed file with surface scratching.

The issue is not in Prusa Slicer and is behaving as expected with z-hop

I found this video https://www.youtube.com/watch?v=XTktr3zNXg8&list=LL&index=7&t=498s&ab_channel=Toffypops i think it can help, but i haven't tested it yet

@LAZER555 @Gork-Mork

This behavior is controllable by config option "Others > G-code output > Reduce infill retraction", disabling this option brings back z-hop on travel moves above already laid out infill. I don't think it's a bug per se, but I do believe it should be off by default, as it takes a while to figure out what's causing the "infill scratching".
