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. Troubleshooting Common Firmware 1

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.

Do you need help configuring a custom Marlin firmware instead of using the stock Anycubic version?

Troubleshooting Common Firmware 1.3.5 Issues

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. |

1. Executive Summary

This report details the significance, feature set, and installation procedures for Firmware Version 1.3.5 for the Anycubic Chiron 3D printer. Released following the initial "boot screen only" versions, v1.3.5 represents a critical stability update that addresses Z-axis probing failures and mesh bed leveling inconsistencies. It is widely considered the last "official" stable stock firmware before community custom firmware (such as Tiny Machines or Jyers) became the preferred standard for advanced users.

2. Auto-Leveling (25-Point Mesh)

• Run Prepare > Auto Level. The printer will probe 25 points.
• Wait for the mesh to complete. The new firmware now saves this mesh automatically.
