How to Level Your 3D Printer Bed the Right Way
Share
If there's one skill that separates good prints from bad ones, it's bed leveling. Do it right and every print starts on the right foot. Do it wrong and nothing works.
Why leveling matters The nozzle must be the exact same distance from the bed at every point. If one corner is too close, you get elephant's foot. Too far, and the print won't stick. Even a 0.1 mm difference shows up on the first layer.
The paper test (manual leveling) This still works for 90% of printers.
- Preheat bed to 50–60 °C and nozzle to 200 °C
- Disable steppers (or use "move axis" to home the Z)
- Fold a piece of printer paper in half
- Place it under the nozzle
- Adjust the bed knob until you feel slight drag on the paper
- Repeat at all four corners and center
- Re-check each corner after adjusting one (it affects the others)
How tight is "just right"? The paper should slide with slight resistance—like a zipper. If it slides freely, the nozzle is too high. If it tears or the nozzle digs in, too low.
Auto-leveling If your printer has BLTouch or similar:
- Set it up correctly (probe offset Z)
- Run auto-level before every 5–10 prints
- Still do a manual "paper test" on the corners—auto-level doesn't fix a warped bed
When to re-level
- After every 10 prints (or sooner)
- After moving the printer
- After changing build surfaces
- After a failed print that knocked the bed
- When first layer quality suddenly drops
Common leveling mistakes
- Leveling cold: plastic bed dimensions change with heat
- Adjusting one corner without re-checking the others
- Leveling too tight (elephant's foot)
- Ignoring a warped bed (auto-level compensates slightly, but a badly warped bed needs a new one)
Spend 5 minutes leveling before a big print. It takes longer to re-level a failed print.
Every Arkforge PLA spool is consistent, so once your bed is level, your first layer will be too.
