Nozzle dragging over print
So since I’ve been using Duet I cannot seem to get rid of the nozzle dragging across the layer it’s printing, it causes some stringing and I can hear the drag when the hotend is traveling.
Any ideas on what I should be changing?
Z steps are basically perfect, +100mm is within .07-.10mm. My first layer also lays down great
Cura has the correct filament diameter also. My extruder is also calibrated to within.07-.10mm
Heres a picture of my top layer, this is happening starting from like layer 4 and gets to this point. Don’t mind the blob, messed up on my end code in cura, nozzle dropped into the print haha

Make sure that the Cura combing setting is set to "No Skin". If you don't do that, it will allow travel moves to cross skin areas without retraction or z-hop. Can you please post your gcode so I can see if there's anything odd about it?
Thanks for chiming in, I wasn't using combing but just turned it on.
Are you wanting the actual file, or the whole gcode?
Also printing another one now with a extrusion multiplier of 90, looks better. also scaled the overall size from 20x20x5 to 30x30x5
Heres what this one looks like at 90% extrusion multiplier
Sorry, what I meant was, don't use combing set to "All", either turn combing off or set it to "No Skin".
I set it to skin when i had it on. Now i turned it back off, and now for some reason every line it puts down its doing a retract. like every line other than outer walls
Just loaded a older Gcode file i had, no issues with that one. i must have did something wrong here.
If you don't do that, it will allow travel moves to cross skin areas without retraction or z-hop
I think that is a part of the puzzle I've been looking for ? , Cura don`t make it simple for you does it ?, I've been looking for some sort of lift while traveling command.
So just an update. for some reason cura was giving me really crap prints. I downloaded Slic3r and configured it, and man my first print from it was pretty flawless. Seems like Slic3r slices better than Cura. The one thing I hated about cura was that it would travel to the next layer then lift z to start printing, Slic3r does the opposite and lifts head then moves.
Yeah I could use Z hop on Cura, but that always gave me a poorer print.
Will post a picture of the difference
Far right is a Slic3r print, the two on left are from Cura, all pictures printed with .2 layer height.
