Top layer defects: What causes this?

[4ndrew]

P1S, default settings for generic PLA. Using Inland “wood rainbow” PLA.

I’m printing a bookmark (.5mm) and finding that the top layer is getting some imperfections. Most are just right here, with a few other fairly minor small spots.

Still pretty new to this, so not sure where to start troubleshooting. My next step after this was going to be investigating ironing settings.

Thanks!

Your print actually looks okay

Those dots are the spots where printer tries to fill the gaps
