Ender 3 V2 Neo Help

Yes, I'm using PLA, just the stuff that came with the printer, but i have a new roll of black PLA from Amazon. I have the bed temp set at 60, 65 this time, for the first layer test, however, its doing the same thing. Not adhering at all.

Did you clean the bed surface?

Have you checked the initial nozzle distance from the bed using a piece of writing paper and adjust using the bed leveling screws until the nozzle just rubs the paper.

If that is correct then check if there is any 'Z' offset set in your slicer settings. Make it zero after the paper nozzle check.
Do another first layer test.

Reduce it by minus 0.01mm or minus 0.02mm and do another first layer test and see if things improve, repeat until you are appy with the first layer.

First, because you got your printer second hand, do a factory reset - who knows what's in your settings.

Second, watch the linked video. Don't obsess over how much drag on the paper is right, the important thing is that it feels the same at all four corners.

Third, the Creality plastic bed gives up the ghost pretty quick. You should use hairspray (Aqua-Net, unscented) to assure adhesion. This is by far better than glue stick or any of the common alternatives. Expensive specialty alternatives like Magi-Goo might work great as well, but Aqua-Net works perfectly, so why bother?

All that done, I think you'll have a much better time of things. The 'v2 Neo is a solid printer.
