Bambu Lab releases firmware updates regularly that add features, improve reliability, and fix bugs in their printers. Updating takes about 5 minutes and the process is straightforward from the printer’s touchscreen or from Bambu Studio. This guide walks through both methods and covers what to do if an update causes issues.
Method 1: Update from the Printer Screen
This is the simplest method. On your Bambu Lab printer’s touchscreen, navigate to Settings (gear icon) then Firmware. The printer will check for available updates over WiFi. If an update is available, you’ll see the version number and a brief changelog. Tap Update and confirm. The printer downloads and installs the firmware, then restarts. Total time: 3-8 minutes depending on download speed.
Important: don’t power off the printer during a firmware update. A failed mid-update is rare but can require a recovery process. Let it complete fully.
Method 2: Update from Bambu Studio
Connect Bambu Studio to your printer over the network. In the Device tab, select your printer. If a firmware update is available, a notification appears at the top of the device panel. Click Update Firmware and confirm. The process runs identically to the touchscreen method.
Bambu Studio also notifies you on startup when a new firmware version is available for a connected printer.
Frequently Asked Questions: Bambu Lab Firmware Updates
Should I always update Bambu Lab firmware immediately?
Generally yes, but it’s reasonable to wait a few days after a major release to see if the community reports any issues. Check the Bambu Lab Reddit (r/BambuLab) after a firmware release. If no significant problems are reported within 48 hours, update. Most updates are straightforward improvements worth applying.
What if my Bambu printer has problems after a firmware update?
First, run the full calibration sequence (first layer calibration, flow calibration) after a major firmware update, as these values sometimes reset or change with new firmware. If print quality issues persist, check Bambu’s support pages and the r/BambuLab community, which usually has solutions within hours of common post-update issues appearing.
Can I roll back Bambu Lab firmware?
In most cases, no. Bambu Lab does not officially support firmware rollback. This is one reason to wait briefly after a major release before updating if your workflow depends on consistent printer behavior.
