How to Fix Error Code 0700_0004

  1. Check Bambu Lab Cloud Service Status

  3. Verify Your Wi-Fi Connection

  4. Restart Your Router and Modem

  5. Sign Out and Sign Back Into Your Bambu Account on the Printer

  6. Check and Update Printer Firmware

    Do not interrupt a firmware update. Ensure the printer stays powered on throughout the update process.

  7. Check Firewall and Router Security Settings

  8. Factory Reset Network Settings on the Printer

    A network reset will erase saved Wi-Fi credentials and account login from the printer. You will need your Wi-Fi password and Bambu Lab account credentials ready to reconnect.

When to Call a Professional

Error code 0700_0004 is almost always a software, network, or account issue and does not require professional repair. However, if you have verified that the Bambu cloud is online, your internet connection is working, firmware is up to date, and you have performed a full network reset with no improvement, contact Bambu Lab support directly at support.bambulab.com. Their support team can inspect your account's cloud sync status on the server side and identify any account-level issues that cannot be resolved from the printer itself.

Frequently Asked Questions

Can I still print when error 0700_0004 appears on my Bambu Lab P1S?
Yes. Error 0700_0004 only affects cloud sync — it does not disable the printer itself. You can continue printing by switching to LAN-only mode in Bambu Studio, which connects directly to the printer over your local network without needing cloud access. You can also use an SD card to send print files directly to the printer.
Why does my Bambu P1S keep losing cloud connection?
Recurring cloud sync failures are usually caused by an unstable Wi-Fi signal, a router that periodically assigns a different IP address to the printer (try setting a DHCP reservation), intermittent internet outages, or Bambu Lab server maintenance. Make sure your printer is within good range of your router, and consider assigning it a static IP address in your router's admin panel.
Does error 0700_0004 mean my Bambu Lab account is banned or suspended?
Not necessarily. While an account issue could cause cloud sync to fail, error 0700_0004 most commonly points to a network connectivity or session token problem rather than an account suspension. Sign out and back into your account on the printer first. If you suspect an account issue, log into the Bambu Lab website in a browser to verify your account is in good standing.
Will a factory reset fix Bambu Lab P1S error 0700_0004?
A full factory reset is a last resort and is rarely necessary for this error. Start with a network settings reset (Settings > Network > Reset Network Settings) and re-entering your account credentials, which is much less disruptive. Only perform a full factory reset if all other steps have failed, as it will erase all printer configuration, calibration data, and settings.
How do I check if Bambu Lab cloud servers are down?
Visit status.bambulab.com to see the official Bambu Lab service status page. You can also check the Bambu Lab community forum at community.bambulab.com, the Bambu Lab subreddit (r/BambuLab), or their official social media accounts where outages are typically reported. If many users are reporting the same error at the same time, it is likely a server-side issue.
