Date: October 26, 2023 Subject: Analysis, Feature Set, and Installation Guide for Anycubic Chiron Firmware v1.3.5
| Use 1.3.5 if… | Consider newer (or custom) firmware if… | |-------------------|---------------------------------------------| | Your Chiron is on 1.3.0 or 1.3.2 and unstable | You want thermal runaway protection improvements beyond 1.3.5 | | You need a reliable baseline before troubleshooting hardware | You’re using a BLTouch, filament sensor mod, or different stepper drivers | | You prefer official, “set and forget” firmware | You want advanced Marlin features (linear advance, S-curve acceleration) |
Later official versions (1.3.9, 1.4.0) exist but are rare; many users jump directly to community builds like Knutwurst’s Marlin for Chiron, which offer better safety and features while keeping the stock screen.
Even with a successful Anycubic Chiron Firmware 1.3.5 download, you may encounter hiccups. Here is how to solve them.
| Problem | Solution |
| :--- | :--- |
| Screen stuck on “Updating” | The .bin file name is wrong. Rename it to update.bin. If that fails, reformat the SD card as MBR (not GPT) using Disk Management in Windows. |
| Printer beeps constantly after update | You selected the wrong motherboard version. Download the alternative Chiron_V1.3.5_Trig131.bin if you have a Trigorilla 1.3 board. |
| Auto-leveling fails at point 13/25 | The inductive sensor is too high. Loosen the sensor’s lock nut, lower it until it is 2mm above the nozzle tip when hot, then re-tighten. |
| Nozzle crashes into bed after update | Your Z-offset was reset. Immediately turn off the printer, manually raise the Z-axis, then re-calibrate Z-offset without running auto-level first. |
| Filament runout sensor not working | Go to Settings > Sensor and ensure “Filament Runout” is set to “On.” The update defaults it to off for safety. |

is a large-format FDM 3D printer that has undergone several firmware iterations. Version 1.3.5 is a factory-distributed update often found on newer Chiron units or provided directly by customer service to resolve specific hardware communication errors. Unlike standard open-source Marlin builds, this version is frequently distributed as a compiled package containing both motherboard (.hex) and screen (.bin) firmware components. 2. Official and Community Sources
Version 1.3.5 is notably absent from many of Anycubic's primary English support pages, but it can be found through regional repositories and community archives:
Direct Download (Official CN Server): The official Chinese Anycubic support site hosts the Chiron v1.3.5 ZIP package.
GitHub Repositories: Users have uploaded requested source files and compiled versions to GitHub Issue Threads to assist those with "bricked" screens or broken factory installs. 3. Installation Procedure
Updating to v1.3.5 typically follows one of two paths depending on the file format received: Method A: Cura Slicer (Standard .hex)
Connect the printer to a PC via a high-quality USB data cable. Open Ultimaker Cura and navigate to Manage Printers Select the Anycubic Chiron and click Update Firmware.
Choose Upload Custom Firmware and select the v1.3.5 .hex file. Method B: SD Card (For Screen/TFT Firmware)
Warning: Users have reported that flashing the screen firmware included in some 1.3.5 ZIP files can lead to an unresponsive display.
If necessary, the .bin file is placed on the root of a formatted SD card and inserted into the display's dedicated slot (not the printer's main slot) before powering on. 4. Known Issues and Stability
While v1.3.5 aims to fix file offset errors and power-loss recovery, it has a documented history of community-reported bugs:
Screen "Bricking": Flashing the screen firmware without specific instructions from Anycubic often results in a permanent progress bar or total loss of touch functionality.
Homing Failures: Some users reported that Z-homing functionality, which worked on v1.3.0, failed immediately after updating to v1.3.5.
Auto-Leveling Conflict: Downgrading or incorrectly flashing the firmware often breaks the printer's unique 25-point auto-leveling system. 5. Recommended Alternatives
Due to the lack of official documentation for v1.3.5, many advanced users recommend transitioning to community-maintained Marlin 2.x builds:
Nick Wells Marlin 2.0.7: A popular stable alternative that supports the stock Chiron hardware while adding features like Linear Advance and improved thermal runaway protection.
TH3D Unified Firmware: A simplified Marlin branch that allows for easier configuration via VSCode.

can be a journey, as it is often pre-installed on newer units but notably absent from some of Anycubic's primary global support pages. The Story of Version 1.3.5
For many Chiron owners, version 1.3.5 is the "missing link." While the Anycubic support site frequently lists version 1.3.0 as the latest available, many printers actually ship with v1.3.5 pre-installed. Users who accidentally "updated" to 1.3.0 from the official site often found their printers downgraded, losing critical features like the auto-leveling function or compatibility with newer TFT screen panels. Where to Download
Because it isn't always on the standard English support page, you may need to look at specific direct or regional links:
Direct Official Link: A known direct download link for the v1.3.5 firmware package is hosted on Anycubic's CN servers.
Customer Support: Many users have successfully obtained the HEX file by emailing Anycubic Customer Service directly, particularly if their machine is experiencing stability issues. How to Install
Once you have the .hex file, the most common way to flash it is through a slicer:
Connect Your Printer: Use a USB Type-B cable to connect the Chiron to your computer. Open Cura: Go to Preferences > Configure Cura > Printers.
Update Firmware: Select your printer, click Update Firmware, and choose Upload Custom Firmware.
Select the File: Point Cura to the v1.3.5.hex file you downloaded.
Important Warning: Avoid flashing the screen firmware included in some ZIP packages unless absolutely necessary, as users have reported this can "brick" the display, making the printer unusable except through external software.

Anycubic Chiron Firmware 1.3.5: Essential Guide and Download
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 v1.3.5 serves as a stable baseline for the Chiron's Trigorilla motherboard. Key improvements typically include:
Thermal Runaway Protection: Enhanced safety protocols to prevent overheating.
UI Bug Fixes: Smoother navigation on the touchscreen interface.
Leveling Accuracy: Refined handling of the 25-point auto-leveling mesh data. Where to Download
You should always source firmware directly from the manufacturer to avoid bricking your machine with incompatible code. Official Source: Anycubic Official Support & Downloads
File Format: Look for a .hex file typically titled Anycubic_Chiron_V1.3.5.hex. How to Install the Firmware
To flash the firmware, you will need a USB cable and a computer with Cura or PrusaSlicer installed.
Connect: Link your PC to the Anycubic Chiron via the USB port.
Prepare Cura: Open Cura and go to Settings > Printer > Manage Printers.
Update: Select your Chiron profile and click Update Firmware.
Upload: Choose "Upload Custom Firmware" and select the downloaded .hex file.
Wait: Do not disconnect the cable or power off the printer until the progress bar completes and the printer reboots. Post-Update Calibration
After updating to 1.3.5, it is highly recommended to perform these three steps:
PID Tuning: Recalibrate your nozzle and bed heating to match the new firmware’s logic.
Re-Level: Clear your old mesh and run the 25-point "Probe" cycle again.
E-Step Check: Verify your extruder calibration to ensure flow remains accurate.
Note: If you have upgraded your Chiron with a BLTouch or a different mainboard (like a BigTreeTech SKR), this stock firmware is not compatible. You will need a custom Marlin build instead.
Firmware 1.3.5 for the Chiron typically comes as:
The file size is usually around 180–220 KB. If you see a file named Chiron_TRI_1.3.5.hex, “TRI” refers to the Tricolor model (some Chiron variants use the same firmware).
