How to Fix Error Code 0700_0002
-
Do Not Power Off the Printer Immediately
Do not press the power button repeatedly. Sudden power cycling during a firmware issue can corrupt the printer's storage. -
Perform a Clean Restart
-
Check Your Wi-Fi Connection Stability
-
Re-attempt the Firmware Update via the Bambu Lab App
Do not close the app, let the printer go to sleep, or lose Wi-Fi connection during the firmware update process. -
Update Firmware via Local LAN (Wired or LAN Mode)
-
Manually Flash Firmware Using an SD Card
Make sure to download firmware specifically for your printer model. Installing firmware meant for a different model can brick the printer. -
Factory Reset as a Last Resort
A factory reset will delete all saved settings, Wi-Fi profiles, and calibration data. You will need to re-run the full calibration process after the reset.

When to Call a Professional
If you have attempted all steps including an SD card firmware flash and factory reset and the error code 0700_0002 still appears, the printer's internal storage (eMMC or NAND flash) may be physically damaged or corrupted beyond software repair. At this point, contact Bambu Lab Support directly at support.bambulab.com to open a warranty or out-of-warranty repair ticket. Do not attempt to open the main electronics enclosure yourself, as doing so may void your warranty.Frequently Asked Questions
Will error code 0700_0002 delete my print files or settings?
The error itself does not delete your files or settings. However, if you perform a factory reset to resolve the issue, your Wi-Fi settings, calibration profiles, and saved configurations will be erased. Your print files stored on the microSD card will not be affected by a factory reset.
Can I still print with error code 0700_0002 on my Bambu Lab printer?
In most cases, printing may be blocked until the firmware issue is resolved because the printer requires a successful firmware state to operate safely. Some users report being able to dismiss the error temporarily and print, but this is not recommended as the printer may be running on incomplete or corrupted firmware.
Why does my Bambu Lab firmware update keep getting interrupted?
The most common reasons are an unstable or weak Wi-Fi signal, a congested 2.4 GHz network, a power fluctuation, or temporary issues with Bambu Lab's cloud servers. Using a wired Ethernet connection or flashing via microSD card eliminates most of these causes.
How do I find the correct firmware file for my Bambu Lab printer model?
Visit the official Bambu Lab website at lab.bambulab.com and navigate to the Support or Downloads section. Select your exact printer model (e.g., X1 Carbon, P1S, A1 Mini) to find the correct firmware file. Never use a firmware file intended for a different model, as this can cause serious damage to the printer.
How long does a Bambu Lab firmware update take?
A standard Bambu Lab firmware update typically takes between 5 and 15 minutes from download to completion, depending on the size of the update, your internet speed, and your printer model. During this time, keep the printer powered on and maintain a stable network connection. Do not interact with the printer or close the Bambu app until the update is fully complete.
