I'm printing with PLA on a "PEO" print bed (really a textured PEI), on my heavily modified ender 3, and there's a pattern on the bottom of my first layer that I'm trying to get rid of. The top of the first layer looks fine, and changing the z offset in either direction doesn't help. I've also tried slowing down the print speed because I thought the extruder might be skipping, but I'm still seeing it at 10mm/s. Any idea what could be causing it, and how to get rid of it?

Edit: the first layer went down from the bottom left to the top right, but the pattern I'm seeing is perpendicular to the extruder path

It was out of mind until I got this new build plate with a fancy texture that I want to imprint on my prints.

Not sure how much this is worth, but it seems to me what happens is that a flap squeezes out forward when you're a little too close, or when the bed isnt adhering well to the material, which can be sometimes improved with some more heat. By habit I always clean with Isopropyl and I notice it less on my textured Prusa bed.
