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. Anycubic Chiron firmware version 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.

For the Anycubic Chiron, firmware version is a specialized release primarily intended for newer hardware revisions of the printer. While many users expect to find it on the standard support pages, it is often not listed alongside the older 1.3.0 version. Key Firmware Facts Hardware Dependency

: Version 1.3.5 is specifically required for Chirons fitted with a newer style of TFT touch panel. Using the older 1.3.0 firmware on these newer panels can cause the screen to stop functioning. Pre-Installation

Step 1: Prepare the SD Card

Format the microSD card to FAT32.
Extract the downloaded ZIP file.
Copy the .bin file (e.g., Chiron_V1.3.5.bin) to the root directory of the SD card. Do not place it inside any folder.

Step 3: Insert the SD Card

Insert the microSD card into the mainboard slot (not the front LCD card slot). On V4.x boards, this is located next to the USB-B port on the front-left underside of the printer. You may need to reach underneath.

Hardware Requirements

Printer Model: Anycubic Chiron (Verified via sticker on the back of the chassis).
Motherboard Version: This firmware is designed for the standard Tri-gorilla motherboard shipped with Chiron units. Note: If the user has upgraded to a third-party motherboard (e.g., SKR or MKS), this firmware is incompatible.
MicroSD Card: A FAT32 formatted SD card (capacity between 4GB and 32GB) is required. SDHC cards larger than 32GB often fail to boot the firmware update due to filesystem limitations.

4. Filament Runout Sensor Refinements

Older firmware would sometimes pause mid-print incorrectly due to sensor chatter. The 1.3.5 release includes debounce logic to prevent false triggers while maintaining immediate pause when filament actually runs out.

4. Known Limitations

While v1.3.5 is a stable "stock" firmware, it retains several limitations that the 3D printing community has noted over time:

Thermal Runaway Protection: While enabled, the implementation in stock firmware is sometimes slow to react.
No Manual Mesh Editing: Users cannot edit specific points in the mesh map on the screen; they can only reset and re-probe.
Safety Features: Stock firmware often lacks the granular safety configurations found in Marlin 2.0 bugfix branches used by custom firmware developers.
ABL Baud Rate: Some users report communication timeouts if the probing speed is set too high.

Should You Stick with Stock 1.3.5 or Switch to Marlin Community Firmware?

This is a crucial fork in the road. The official 1.3.5 firmware is stable, but some advanced users prefer community builds (e.g., Knutwurst’s Marlin 2.x for Chiron).

Where to download

Always download firmware only from official Anycubic resources (official website, support portal, or vendor-provided links) or well-known community firmware repositories that explicitly reference the Chiron and the file’s target board. Verify checksums (MD5/SHA256) when available.
