Here’s a guide to help you resolve these issues:
- Verify Proper Bed Plate Installation
Ensure Correct Placement: Confirm that the build plate is correctly seated, with all corners flush and the back tab properly aligned. An improperly seated plate can lead to leveling errors.
- Perform Manual Bed Tramming
Initial Knob Adjustment: Begin by setting the bed leveling knobs so that the screws and knobs are flush, providing a consistent starting point.
Execute Tramming Procedure: Utilize the bed tramming G-code provided by Bambu Lab. This process involves the printer moving to specific points, allowing you to adjust the knobs so the nozzle just touches the bed surface at each location.

- Tighten Bed Leveling Knobs
Secure the Knobs: After tramming, ensure the bed leveling knobs are adequately tightened to maintain tension. Loose knobs can cause the bed to drift out of level during printing.
- Inspect for Obstructions and Hardware Issues
Check for Debris: Examine the bed and surrounding areas for any debris or filament remnants that could interfere with bed movement or level sensors.
Inspect Bearings and Guide Rails: Ensure that the bearings on both guide rails are free from obstructions. Debris in these areas can affect bed movement and leveling accuracy.
- Run Calibration and Bed Leveling Procedures
Automatic Calibration: After manual adjustments, perform the printer’s automatic calibration and bed leveling routines to fine-tune the bed alignment.
