First Layer Inspection Failed - AI Detected Print Defect on First Layer
Quick Answer
Error code 0500_0100 on your Bambu Lab FDM 3D Printers means: First Layer Inspection Failed - AI Detected Print Defect on First Layer. This is usually fixable — see the step-by-step guide below.
Likely Causes
  1. Z offset is incorrect causing the first layer to be too high or too low
  2. Build plate not clean resulting in poor adhesion
  3. Warped bed causing uneven first layer height across the surface
  4. Incorrect plate type selected in Bambu Studio (textured vs smooth PEI)
How to Fix It
1
Clean the build plate with isopropyl alcohol (90% or higher) and a lint-free cloth
2
Recalibrate the Z offset using the printer calibration wizard on the touchscreen
3
Verify the correct plate type is selected in Bambu Studio under the Plate settings
4
Run the full auto-calibration sequence: vibration compensation, flow calibration, and bed leveling
5
If the AI false-triggers frequently, you can disable first layer inspection in the printer settings (not recommended for unattended prints)
Pro Tip
This is a common issue that most users can resolve without specialized tools. Try the first step before moving on to more complex solutions.
