Tronxy XY-2 Pro does not flash over USB (only prints over USB). You must use an SD card (≤8GB, FAT32).
Process for V5/V6 (Marlin 2.0):
Process for V1.4 (Marlin 1.1.x):
Tronxy doesn’t have a clean auto-updater. Get firmware from:
Tronxy Wiki (sometimes updated)
3D printing forums (GitHub, Reddit r/Tronxy, Facebook Tronxy group) – often community-modified Marlin 2.1.x is better than stock.
What you need:
Method 1 – Cura (Easiest):
Method 2 – Arduino IDE (if Cura fails):
The LCD screen usually has a version sticker on the back of its own PCB. If you have a full-color touch screen (TFT) vs. a monochrome LCD, the firmware files are completely different.
Critical Warning: Flashing the wrong version will "brick" your screen or make the printer unresponsive until you re-flash the correct file.
Updating the Tronxy XY-2 Pro involves updating the TFT screen and the mainboard separately in some cases. Here is the standard procedure:
Install Klipper firmware (if you have a Raspberry Pi). Search: “Klipper on Tronxy XY-2 Pro” – gives input shaping, pressure advance, faster prints. Requires complete re-flash of mainboard.
Need a direct download link?
I can’t post live links, but search GitHub for “Tronxy XY2 Pro Marlin 2.1” – the repo by Neo2003 is current (2024/2025).
If you share your mainboard version and current firmware version, I can narrow down the exact file.

Do i NEED to upgrade the firmware to marlin on my Tronxy xy2 pro?
To update the firmware on your Tronxy XY-2 Pro Go to product viewer dialog for this item.
as of early 2026, you can choose between the official manufacturer's firmware or community-driven Marlin builds. Step 1: Identify Your Current Hardware & Firmware
Before downloading any files, you must identify your specific motherboard to avoid "bricking" the device.
Check the Boot Screen: Marlin-based printers show boot info at the bottom; older "Chitu" firmware versions (like V1.4) do not. Inspect the Motherboard:
Open the bottom panel to find the version number. Common versions for the include CXY-V6-191017 .
Check the MCU: Note if your board uses an F103 or the newer F446 chip, as update methods differ for 2021+ boards. Step 2: Backup Your Current Configuration Always save your existing settings before a fresh flash.
Download a settings backup G-code script (available on GitHub Save it to an SD card and "print" it on your
Wait 30 seconds, then turn off the printer. You will now have a currentconfig.gcode file on your card with your original steps-per-mm and PID values. Step 3: Choose and Download Your Firmware
Official Firmware: Best for stability. Download the latest V2.0 parameter files or Marlin versions from the Official Tronxy Store.
Community Marlin: Offers advanced features like "Live Z" adjustment. Reliable builds for 2025/2026 can be found on repositories like MystyJoy's GitHub. Step 4: Flash the New Firmware
Most modern Tronxy boards allow for "SD card flashing" without a PC connection. A. Standard SD Card Method
Format the Card: Use a FAT32-formatted microSD card (ideally 8GB or smaller). Prepare Files: Create a folder named update in the root directory. Place your compiled firmware.bin file inside.
Rename it to fmw_tronxy.bin (though some versions may require different names like update.cbd). Tronxy XY-2 Pro does not flash over USB
Install: Turn off the printer, insert the card, and turn it back on. The machine should beep or show a progress bar. Do not power off until the main menu reappears. B. Manual "Unlocking" for 2021+ Boards (If SD Method Fails)
If your board is locked (common in 2021+ F446 models), you may need to use STM32CubeProgrammer:
Open the bottom panel and move the BOOT jumper to the "boot" position. Connect the printer to your PC via USB.
Use the STM32Cube tool to "Full Chip Erase" and then upload the new firmware binary.
Move the jumper back to the original position once complete. Step 5: Post-Update Calibration After updating, your previous settings may be wiped.
Restore Settings: "Print" your currentconfig.gcode file from Step 2 to restore your old calibration.
PID Tuning: Re-run PID tuning for your hotend and bed to ensure temperature stability.
Z-Offset: Since the firmware has changed, perform a fresh bed leveling and set your Z-offset before your first print.
