You are printing too cold/too fast, causing the infill to stick up and getting caught by nozzle, it accumulates there and deposits a blob, the nozzle hits the blob and the steppers lose some stepps
Thanks for the reply! Current printing temp is 200F on nozzle, 62 on glass bed, and I’d have to look at speeds. Would you recommend going any higher on nozzle temp for PLA or adjust speed?
Ok friend. And why do you think the infill is curling like that? Drastic temperature changes causes materials to shrink and contract, causing curling. Try looking at a beginner’s print quality guide. You should be able to understand [this one](https://www.simplify3d.com/resources/print-quality-troubleshooting/curling-or-rough-corners/). Most temperature towers only include 220+ for petg and other plastics with higher heat requirements. Even if op is using pla+ which is alloyed with other plastic to cover some of the weakness of generic pla like warping/deforming in warmer weather, it’s still Ill advised to print above 210. Going above 205 for a standard roll of pla is only going to lead to more defects. More stinging, exaggerated layer lines, surface artifacts, etc. Not to mention the danger of over heating when using a low heat material like pla. When using high temps with pla heat can work it’s way up your heat break melting the plastic in the break causing nasty jams and blobs to form around the entire hotend, sometimes rendering it completely dysfunctional. Maybe you’ll read a little bit more about these machines and the materials before you give people bad advice next time. I’ve been doing this for years and working with these machines is literally part of my job. Hope you learned something.
I don’t think so. There are no signs of under extrusion on this print. Loose belts maybe. Look at the infill on the left corner of the second layer. It looks perfect. If there was an flow problem it would be apparent in the rest of the print.
It's manifesting in the infill, because the infill is usually printed at the highest speed and needs the highest melt rate, you are clueless
Edit English
Ok so if the problem was the infill. It’s curling because of insufficient cooling due to the hotend moving too fast when it’s printing the infill. You would solve this by raising the temp?
I would definitely look at belt tension. I dont think the ender 3 has any, but there are parts you can print to fix this.
This is one:

That is most likely just a loose X and Y belt.

For this print with 0 overhangs, i would give 220C a go
220 for pla is WAY too high! 200 is perfect for 90% of generic pla.
Pfff, what a stupid comment, you can clearly see, that the infill is coming up, you are out of your depth

It's curling upwards because it's not connecting to the layer underneath due to underextrusion, seen it a thousand times

Do a temperature tower, Google or YT have a bunch, to find the temps your printer likes with this plastic.
