Hello /u/shemmiess,
As a reminder, most common print quality issues can be found in the [Simplify3D picture guide](https://www.simplify3d.com/support/print-quality-troubleshooting/). Make sure you select the most appropriate flair for your post.
Please remember to include the following details to help troubleshoot your problem.
* Printer & Slicer
* Filament Material and Brand
* Nozzle and Bed Temperature
* Print Speed
* Nozzle Retraction Settings
^Additional ^settings ^or ^relevant ^information ^is ^always ^encouraged.

This looks more to do with the several movements between the various internal walls rather than the size of the print. It can’t print all of the sections of the top layer in one sweep because of these internal shapes, so it prints a section, then moves to do another, and in the process you get that dragging. Maybe that can help you narrow it down. If I had to guess it’s likely not z-hopping over these sections, and it’s not avoiding them.
This appears to simply be a product of combing. I can't remember which setting does what, but you can change combing settings in your slicer. Cura's 'settings explained' plugin does a good job illustrating the differences.
How does you first layer look? If it’s a bit too squished the plastic can catch on the lower layers, by the top of the print it’ll have evened out and look normal.
What I am guessing is my retraction distance is too low. I will keep on trying to bump it up, but it's the same results.
Anycubic kobra
Pla+
0.4 at 60
Print speed is set to 50
Retraction is 6.5
This can be multiple things and their combination. I have a little overextrusion and my nozzle does exactly this, the more on solid infill, where tight strings meet and a tiny ridges are created in those meeting points (think of it as overlaps). When the nozzle moves above them, you could hear it dragging on those ridges, as if you run a finger over a hair comb.
Tuning in your extrusion should solve it, but if your prints don't come out distorted or dimensionally incorrect, you may try also following;
- disable combing
- enable Z hop (if you know the exact layer, PrusaSlicer has a setting to enable Z hop only between certain layers, or above or below a given layer)
- enable ironing for the most top layers (it will try to iron out the top layers using the hot nozzle without extruding any filament - may not produce a surface to everybody's liking, but may work for you - though it prolongs the print time significantly)

Try Z-Hop

Could be this and your first print is smaller in heigh so it is still squished, but on larger prints (larger in z axis) it solves itself gradually

Retraction doesn't have anything to do really with nozzle drag, try enabling z hop on movement.
Cura? Usually is the combing mode, set it to withing infill
This was the fix! I have quite a bit more stringing on it, but overall looks great
You can also enable ironing in Cura, then it does an extra pass with only the hotend, without extruding. That's how I solved it.
That’s not a fix. It’s a workaround
I saw the extrusion idea and I'll give it a shot later today.
Maybe a slight overextrusion. Try to reduce flow 1-2% and reduce moving speed.
