This is the trickiest part of bed leveling and certainly one that you'll get better at with practice.
- Slide a sheet of paper between the printing nozzle and the print bed.
- Simultaneously raise the print bed toward the nozzle by rotating the wheel clockwise, while sliding the sheet of paper back and forth.
- When you feel the slightest tension on the paper, stop. It feels almost like the paper is vibrating.
Repeat this process two times around, on each corner of the print bed, moving to the bottom-right, top-right, and top-left.
You'll need to move the print bed to get the nozzle on the different corners of the printing surface. Make sure you're not scratching the surface with the nozzle as you move the print bed.
Next: Upgrade those springs
Now, if you haven't already, you'll want to upgrade the springs on your Ender 3 V2, so you don't have to level the bed endlessly!
