Hi, I’ve been printing for about a year, sometimes even successfully, but on this specific print, the nozzle drags through the layer for no reason. Usually, a Z-Hop prevents that, but on this very print, the Slicer somehow doesn’t add one. I’m using Orca Slicer (dockerized, Linuxserver.io image from last month, 15.09.25) and have enabled Z-Hop in the printhead config (all surfaces). It does add Z-Hops on other moves, just not here. And yes, I know my Z-Offset is a tinge too low, which is part of the problem, but I’d like to focus on Orca Slicer not Z-Hopping first.
Does anyone know about this issue? Slicing with PrusaSlicer works; I can just switch back to that one if I don’t find any features I miss from Orca Slicer.


I don’t have a solution for you, but I just wanted to say that z-hopping sometimes causes more defects than without, in my experience. With my extruder at least, it’s more likely to leave behind a blob if lifting, while with a classic retract+wipe the nozzle stays “plugged”. I also used to get mad at the nozzle going through a layer and leaving a mark, but then realised that it really doesn’t matter unless it’s a top layer. You also save a little little bit of time by not z-hopping.
I do hope you find an answer though, everyone should print with whatever parameters they like :)
Yup, can confirm - I do however rarely print stuff that needs to be pretty, which is why I take the blob over the noise of hearing my nozzle drag over something (and/or potentially knock something loose). Also, “aligned” seams hide the blobs on a lot of prints.
