Bambu Lab Firmware Tracker
The latest firmware for every Bambu printer on one page, with what changed and whether to update
Current state of the lineup
The newest printer firmware is on the H2D (01.04.20.00, November 3), 69 days after 01.04.00.00: a security update, steadier printing with third-party filament and a fix for a failed print start blocking later G-code prints (H2D row). Before that, the P2S (01.03.00.00, September 21) got its first update after a 165-day gap. It adds support for the E3D High-Flow Integrated Hotend and raises travel speed to 1000 mm/s for shorter prints (both need Bambu Studio 2.8.3.66 or later; the first stable release that qualifies is 2.9.1 from November 3), cancels Z-axis motor noise, and loads time-lapse videos faster in Bambu Handy 4.0. The H2S is a moving case: Bambu removed H2S 01.03.00.00 (dated September 16) from its release history and listed it again on November 3, now labeled OTA and without a date, while the firmware download page still offers 01.02.00.00. Until the download page or an announcement confirms the rollout, the table keeps the H2S at 01.02.00.00 (March 31). We found no statement from Bambu on either change. On September 16, the date of the withdrawn build, Bambu opened H2S 01.02.50.00 as an opt-in public beta (joined in Bambu Handy under Me → Beta Firmware Program). It includes a fix for the auxiliary part cooling fan, whose airflow could slightly deform parts when the heatbed sat level with it; that fix needs Bambu Studio 2.8.4 or later, on the stable channel 2.9.1 from November 3. In October Bambu opened two more opt-in public betas: H2C 01.02.50.00 on October 22 (security, plus a fix for a failed print start blocking later prints), which Bambu briefly listed in the H2C release history as 01.02.50.002 and has since removed again (checked November 3, 2026), and 01.08.01.26 for the A1 series on October 27. The download pages still offer 01.02.00.00 and 01.08.01.00, so the table keeps those as current (details in the H2C and A1 rows). Bambu published R1 firmware 01.01.00.00 on September 22, the day pre-orders opened (shipping estimated for November), and the A2L's Print-Then-Cut build (01.01.05.00, September 3) is the next freshest printer update. At the other end, the H2S and the P1P/P1S now wait longest, with no new firmware since their March releases (day counter below).

It retires the legacy queue sync in line with Farm Manager 3.0.0, so the printer no longer syncs and shows the task queue locally, and for offline updates a printer below 01.08.01.00 must first install that version, which Bambu calls the bridge firmwareWear parts & upgrades for A1: hotend swap, maintenance, build plate, AMS jams | Release history |

Days since last firmware update
One number Bambu never shows you side by side: how long each machine has been waiting for attention (as of November 3, 2026).

|---|---|
| H2D | 0 d |
| R1 | 42 d |
| P2S | 43 d |
| A2L | 61 d |
| X1 / X1C / X1E | 91 d |
| X2D | 96 d |
| A1 / A1 mini | 153 d |

| H2S | 217 d |
| P1P / P1S | 218 d |
Update now or wait?
Bambu's own pages tell you what changed; they never tell you whether to install it. Our honest defaults:
- Point releases (last digit pairs): install. They are mostly fixes and security patches, though some carry features (A2L 01.01.05.00 added Print-Then-Cut); waiting buys you nothing.
- Major version jumps: give it a week. New feature waves occasionally ship regressions; the firmware announcement threads surface problems within days. Nothing about printing forces you to be first.
- LAN-mode and OrcaSlicer users: read the notes first. Since the January 2025 Authorization Control change, firmware updates can alter how third-party software reaches the printer. Background: What is Bambu Connect? and the AGPL dispute.
- X1C owners: install it. The August 2026 build is the first in 237 days and carries security fixes, so there is no reason to sit it out. The series is EOL, but Bambu's schedule keeps feature updates and bug fixes coming until May 31, 2027 and security patches until May 31, 2029.
- Betas: opt-in only. Bambu announces public betas in its forum, and you join them in Bambu Handy under Me → Beta Firmware Program; they do not install over the air by default. Skip them on machines you rely on.
How this page works
We check the official release-history pages for all thirteen firmware lines, twelve for the printers plus the R1 laser, and update this table when a new version ships; our news radar covers firmware announcements within hours, and notable releases get a full article (like Bambu Studio 2.8.1 on the software side). For the update procedure itself, including offline updates from SD card, see our firmware update guide.
Source: official Bambu Lab Wiki firmware release histories for all thirteen firmware lines (linked per row), checked November 3, 2026. Firmware versions and dates are Bambu's; status labels and update guidance are ours. The X1-series EOL date (March 31, 2026) is per Bambu's product lifecycle announcement.
