3D printer manufacturer Bambu Lab has issued a new update after an early fix was withdrawn. Termed a critical calibration bug, the company has acted swiftly to deliver new code to its many users.
The Shenzhen-based company has now released firmware version V01.01.02.07 for its H2D 3D printer through its Public Beta Program. Rolled out on May 23, this update introduces a comprehensive set of new features, performance enhancements, and critical bug fixes designed to elevate print quality, expand hardware compatibility, and offer users greater control. The release builds on feedback gathered from earlier beta phases.
Features and Improvements
Firmware V01.01.02.07 adds native support for the CyberBrick time-lapse kit. It also expands the H2D’s onboard AI failure detection system, now giving users the ability to individually toggle detection functions for nozzle clumping, spaghetti printing, air printing, and purge chute pile-ups from the printer’s interface.
Hardware compatibility has been further extended. The AMS 2 Pro and AMS HT systems now support RFID-based automatic matching of drying parameters and can perform drying operations without rotating spools. Additionally, the Laser & Cut module can now initiate tasks directly from USB drive files, improving workflow support.
Performance updates include improved foreign object detection on the smooth PEI plate, better regulation of heatbed temperatures, enhanced first-layer quality, more reliable chamber temperature checks before printing begins, and improved accuracy of laser module flame detection. The update also enhances the accuracy of nozzle clumping and nozzle camera dirty detection, while optimizing the pre-purging strategy.
A collision issue between the nozzle flow blocker and nozzle wiper—previously triggered during flow dynamics calibration—has been resolved. Calibration reliability for the liveview camera has also improved, and issues with pre-extrusion lines sticking to prints during layer transitions have been addressed.
However, two known issues remain in this beta release: detection of filament PTFE tube detachment is currently disabled, and users cannot adjust heatbed temperature via the Bambu Handy app. The latter is expected to be fixed in a future app update.
This version replaces V01.01.02.04, which was briefly released on May 20 before being withdrawn due to a critical calibration bug. That earlier version caused the right nozzle to crash into the wiper during left-nozzle calibration, damaging the printer. The firmware also temporarily disabled filament detachment detection. Bambu Lab quickly pulled the update and advised users to revert to the previous stable firmware while working on a corrected release—now realized in version V01.01.02.07.
Accessing the Firmware
To access the beta firmware, users can opt into the Public Beta Program through the Bambu Handy app by navigating to the “Me” section and selecting “Beta Firmware Program.” Once enrolled, the update will be rolled out gradually. Participants can leave the program at any time and revert to the most recent stable firmware version. Bambu Lab recommends updating Bambu Studio Presets before installing the firmware to ensure full compatibility. Full technical documentation and the official changelog are available on Bambu Lab’s website.
Bambu Lab Hardware Line: H2D and Beyond
The new firmware update applies to the H2D 3D printer, Bambu Lab’s flagship desktop manufacturing system unveiled in March 2025. Designed for professional users, the H2D offers the company’s largest build volume to date—350 x 320 x 325 mm—and includes two new AMS systems with integrated filament drying. Dual-nozzle extrusion and servo-driven precision deliver high accuracy, while a 350°C hotend and 65°C heated chamber allow reliable printing with high-performance, fiber-reinforced materials. With a toolhead speed of up to 1000 mm/s and acceleration of 20,000 mm/s², the H2D is built for productivity without compromising quality.
Bambu Lab’s broader portfolio also includes the X1E, released in 2023 as an enterprise-grade upgrade to its X1 series. Developed with professional and engineering applications in mind, the X1E features LAN-only connectivity for secure, offline operation, enhanced air filtration, and precise thermal regulation. An increased maximum nozzle temperature expands its material compatibility, making it suitable for demanding industrial applications. At its core, the X1E builds on the proven performance of the X1 Carbon, extending the system’s capabilities for use in sensitive or regulated environments.
