Firmware 1.3.5 was released by Anycubic to address early adopter concerns regarding the Chiron’s touchscreen interface and thermal runaway protection. Unlike later versions that may introduce restrictive slicing requirements or altered motion planning, version 1.3.5 is often regarded by the community as a "stable baseline" that offers modern features without compromising the open nature of the printer's G-code handling.
Open-source enthusiasts maintain a repository at github.com/AnycubicOfficial/Chiron-Firmware . The 1.3.5 release can be found under the “Releases” tab.
Go to support.anycubic.com , search “Chiron firmware,” and look for archived versions. As of 2025, 1.3.5 may be listed under “Legacy Firmware.”
Anycubic published source code and compiled .hex files for the Chiron (based on Marlin). Check github.com/Anycubic/Chiron for the Firmware v1.3.5 release. Anycubic Chiron Firmware 1.3.5 Download
: Ensure gcode files on your SD card have short names and are in the root directory (not in folders), as the Chiron firmware has limited file navigation support. Custom Firmware Alternative
The Anycubic Chiron, due to its large build volume (400x400x450mm), suffered from initial firmware instability regarding bed leveling. Early versions often failed to save mesh data or would crash during the leveling process.
Updating your Anycubic Chiron to firmware version 1.3.5 is a critical step for improving print reliability and ensuring your machine runs with the latest bug fixes and safety features. This version is specifically designed for the Chiron’s massive build volume and stock hardware configuration. Why Update to Firmware 1.3.5? Firmware 1
