Issue with Ender 3 V2
Hey all,I'm having a problem with my Ender 3 V2. I started seeing faint lines stuck on my build surface that I have never seen before, and my filament does not stick to the plate correctly when printing over those lines. This has never happened to me before. What should I do? (Image attached to show the problem)Thanks!

More info: Speed: 50 (100% on Ender 3 V2) Cooling: on Material: PLA (to be specific BASICFIL 1.75mm, white) Nozzle temp: 220 Bed temp: 70 Z-offset: 0 (Tried changing it to 0.5 and higher but it would not work)

Not sure from the photo what faint lines you mean.
Suggest you use one of the many downloadable bed levelling tests and check the overal bed for high or low spots. Once you have it level try redoing the test and vary the 'Z' offset in 0.01 increments until you get an acceptable first layer thickness.
A 'Z' offset of 0.5 is more than twice the normal 0.2 layer height and you are virtually printing in mid air.
Also give the bed a good clean with some IPA and then preheat before initial nozzle height adjustment prior to bed level test.
A slower speed around 50% for first layer might help.

On the photo they don’t seem that faint, you can see them. But I can’t pull them off.
Will try, thanks.
I’m not sure if I have IPA lying around, what else can I use?
Thanks for your help, will try all of your tips.

Lines could be extruded filament stuck to bed, will probably need to be scrapped off.
If that's a glass bed there is a danger that some glass will come away with any stuck filament, try warming it to normal bed temp first.
Check that you are using the filament manufacturers recommended bed and nozzle temps for for your PLA, maybe try temps in the middle of their recommendations.
Perhaps get some IPA from somewhere like Amazon, mine came in a handy spray bottle and lasts for ages. I use a quick spray and wipe before each print.
A good scrub with some detegent might work but beware leaving a residue film on the bed plate.Last edited by Bikeracer2020; 02-25-2023 at 01:53 AM.

Oh no. I just found out while doing another print that those lines aren't filament, but that they are being scraped on by the extruder. How do I fix this? I don't know how to level the bed for my Ender 3 V2.

Yeah, not anymore. My printer keeps going out of level. And now my extruder doesn't work anymore. Yippee. NEVER AGAIN with Creality
