Unofficial · Bambu Lab printers

Should you update this firmware?

Bambu ships printer updates often. The wiki is long, and forum threads disagree. 3DP Firmware puts the official caveats next to a count of what owners report here. If nobody has reported a version yet, the badge says so. It does not invent a verdict.

Votes start to count at 5 reports: Below that, you will see Needs reports unless the data file sets an editor floor of Mixed or Hold off.
Mixed at 15% · Hold off at 40%: Those are shares of Problem reports on this site, not a lab test. Read the full rules.
