This has happened to me a couple of times on the top layer. Using PLA filament. All the previous layers are nice and smooth.

Looks like under extrusion to me.
Ellis has an excellent guide for tuning, and includes a method to fine tune your issue. https://ellis3dp.com/Print-Tuning-Guide/articles/extrusion_multiplier.html |

The black part?
Can you get the camera to focus on it? |

And also a zoomed out pic as well, for perspective.

On thing we would also need to know is the model itself. If you are using orcaslicer slice the model and change the color scheme to show flow, layer time, and fan speed. Check to see if any of those outputs matchup with where the layer changes color on your printed part. I think ive seen that layer time is sometimes the culprit.

There is nowhere on my 86 fj1200 to keep the registration and insurance papers except under the seat which is a PITA.
So I was attempting to make a "box" to mount on top of the gauge cluster to put them in. Unfortunately it's to big.. lol

Ironing can be finicky, especially with what material you are using. If that is the top surface, you are likely over extruding. You could also have wet filament.

Agree on iver extruding. That can cause those corn row lines.
Try turning down the ironing extrusion %. I think itnis like 15% normally. I usually do 5-10% when I use it, which isn't often. I generally just select a prettier top pattern and call it a day. |

You could also have wet filament. It actually works very well.  I haven't changed any settings except for the perimeter setting. Next time I print something with a large flat surface I'll tweak the extrusion setting. tks folks |
