P2 series
Enclosed single-nozzle printer with a shorter public firmware history than the P1 and X1. The newest package is the one to read carefully: Bambu lists no known issues, and a public forum thread describes first layers sitting too low.

MixedHandy is the usual way to install an older package Bambu still hosts. A Bambu forum thread about 01.03.00.00 includes owners who said rolling back to 01.02.00.00 and recalibrating restored a normal first layer. That is their report, not a test run on this site, and those posts are not counted in the report totals here. If a release note says motor noise cancellation changed, run that calibration again after you move.
Summaries on this site are paraphrases. The version list and the wording of any known issue belong to Bambu's page.

A package dated 9 Feb 2026, between the October launch notes and the April feature release. The wiki table of contents names the version and does not give it a separate known-issue heading we could quote with confidence, so this row stays thin on purpose.
