3D printer bed calibration and test print

by MASTER

Calibrate the printer bed before a print job or after hardware changes to ensure consistent first-layer adhesion. Finish with a short test print to confirm uniform nozzle height and sticking across the build plate.

3D printer bed calibration and test print

⏱ 30분 ★ 보통

현재

Nozzle-to-bed gap varies across the build plate so some areas show gaps in the first layer while others are over-squished or peeling.

난관

Leveling screws, a warped bed, or loose gantry hardware cause inconsistent nozzle height between corners; manual paper-gap adjustments are subtle and it's hard to ensure each corner matches the same distance. Firmware probe offsets or forgotten Z-offset changes can shift the effective nozzle height after adjustments.

기대

Nozzle-to-bed gap is within the target range across the entire bed and a 20 mm calibration object prints with a flat, continuous first layer that adheres without gaps or excessive squish.

재료

• standard printer paper — 1 sheet
• PLA test filament — 20 g

도구

• hex key set — 1
• SD card or USB drive — 1

단계

01

Prepare printer and load file

Turn on the printer, preheat nozzle and bed to the filament's recommended temperatures, and load the calibration G-code onto the printer.

⏱ 5분
02

Clean and inspect bed hardware

Wipe the bed surface until no visible dust or residue remains, check for loose leveling screws or gantry bolts and tighten to finger-tight, then re-home the axes.

03

Coarse leveling with paper

Disable steppers, move the nozzle to the first corner, slide the paper under the nozzle and adjust the corner screw until the paper drags lightly; repeat for all corners and the center, then re-home.

⏱ 10분
04

Set Z-offset and run first-layer check

If available, run the printer's mesh or auto-level routine; print a single-layer skirt or calibration line and adjust Z-offset in 0.05 mm increments until the filament lays a full-width line without gaps or excessive squish.

⏱ 5분
05

Print test object and evaluate

Print a ~20 mm calibration cube or test pattern (~5 minutes), inspect the first layer across the bed and corners for uniform adhesion, and note any spots that need another small corner adjustment.
