First layer woes - looking for advice (lemmy.world)

Hi folks, I've had my ender 3 v2 for around 2 years and it's been trouble-free until lately. Recently, I've had major issues with the first layer. I found a few worn components, so I got a dual gear extruder and replaced the nozzle, recald the esteps, bed level and z offset. Nothing I do seems to work.

The issue happens on the first layer when it first starts to extrude. The first 5mm or so of extrusion curls up behind the nozzle, then the extrusion sticks to the bed and it continues normally... Until it needs to starts a new extrusion, then the same thing happens...the curl.

I have to think it's something with temperature, but I haven't changed anything about the filament since these issues started.

Looking for any advice. Thanks!

What are you using to clean the surface? I had bought some IPA 70%, thinking all IPA was the same. It was not. I switched to IPA 90% and that one problem went away. (I have/had other problems.)
