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!

Someone else mentioned a G10 printing surface. Any idea what's better for PLA? Or what's the difference between the two?

[–] [email protected] 1 points 1 year ago

Not familiar with G10, but my PEI sheet has been the best thing for adherence with PLA I've used in the last 5 years. I've used hairspray, glue sticks, blue tape, glass, and combinations of them. Straight PEI is still better than all of them, for me anyway.

From what I read before I bought mine, smooth PEI works great for PLA, while the textured PEI is better for ABS and other types that have larger adherence issues.
