Having trouble with your first layer? No worries, these simple checks fix the issue in 95 percent of cases:
Your first go-to should always be the official Bambu Lab Wiki for the A1:

- Clean your build plate properly using warm water and dish soap. Make sure it is dish soap for plates, not for hands, to remove any grease or residue.
- Check if bed leveling is turned on. You will find the option in the print menu and it should always be enabled.
- Calibrate your filament. Proper flow rate and flow dynamics are essential to avoid over or under-extrusion.
- Make sure your nozzle is installed correctly. It often helps to remove it once, check the heater screws, and reinstall it carefully.
- Run a fresh calibration under Device then Calibration. This is especially important after firmware updates but can help anytime you have adhesion issues.
Highlights:
- Maximum printable area for A1 printers on MakerWorld
- Automatically skips the purge strip for mess-free starts
- Comfort grip tab for quick and easy removal
- Parametric customization via the MakerWorld Customizer
- Optimized for bed leveling and adhesion diagnostics
Customization Tips:
Fine-tune the gap from purge strip and plate edges directly in the Customize section to match your needs perfectly.
Helpful Advice:
- 2 layers highlight surface inconsistencies without excessive adhesion
- 1 layer shows trouble spots faster but sticks tighter - remove carefully!
- Clean the plate thoroughly using warm water and dish detergent (not hand soap)
- Always run a calibration under Device → Calibration before testing for best results
