Does the nozzle look slightly damaged around the outlet? Could this be causing me issues with the 1st layer and the first fill being rough? Other than the first layer the prints come out really well.
Doesn’t look round.
That’s partly what I was thinking. I wonder if I been to rough when cleaning off filament and somehow damaged the edge.
Will have to try and get a better look at it.
0.5mm
Might be able to using some small drill bits. The photo was using a cheap microscope attachment on iPhone. I’ll be lucky to even see what I’m doing.
The only reason I liked was I was struggling to get a good layer down. It was almost like something was ripping stuff back up. Once I get a layer down it seems to be fine.

Looks like it might be partially clogged around the bottom edge. Not sure how you would be able to clean it better.
You may be starting too close to the bed on your first layer.
Thinking of running a small drill bit through it. Start at say 0.4 and see if it cleans it up.
Worse case I’ll order a replacement as for the cost it’s not spending to much time on.
Wire brush while warm…
If your other layers are fine, I doubt that you’re seriously affected by the nozzle being somewhat imperfect. I agree with @Ben_Malcheski - you’re probably too close to the bed.
Are you printing with PLA? If you are and can remove it, put it in boiling water for a while and the PLA will be softened and easier to remove. Be careful with actual drillbits. They’re going to want to gouge it up. Ideally you’d use a piece of drill rod that doesn’t have flutes, like the back end of the drillbit, and push it through while the material’s soft.
With that said, I somewhat doubt it’s print material because that should heat up and flow out during printing. It could be debris in the print material (I’ve had nozzles clog from that.) It’s also possible the nozzle ran into the bed hard enough to slightly deform it, but that’d take a pretty serious hit and if you’re printing on glass I’d expect it to break the glass.
To me it looks like there is a brim/burr on the tip. Try carefully to peel it off with a sharp razorblade.
The nozzle doesn’t look imperfect, in fact it looks quite good.
