Tronxy Xy-2 Pro Firmware Update ★ ❲Confirmed❳

Title: Tronxy XY-2 Pro Firmware Update: The Safe Guide to Upgrading Your Printer

If you own a Tronxy XY-2 Pro, you’ve likely hit a point where the stock firmware feels limiting. Whether you are tired of the lack of thermal runaway protection, the noisy menus, or you just want to install a BLTouch/3D Touch sensor, updating the firmware is the next logical step.

However, the XY-2 Pro is a bit of a unique beast. Unlike standard Ender 3s, this printer uses a proprietary motherboard layout that can make updating tricky.

Here is a breakdown of what you need to know before you update, along with the safest methods to do it.

2. Update Methods

There are three primary paths for updating the XY-2 Pro firmware:

Part 2: Know Your Hardware Version (Crucial Step)

If you skip this step, you will brick your printer. Tronxy released multiple hardware revisions of the XY-2 Pro. tronxy xy-2 pro firmware update

Check your motherboard: Open the electronics case (bottom or side). Look for the silkscreen text:

Check your screen: The XY-2 Pro usually has a 2.4" or 2.8" resistive touch screen. The screen’s PCB revision matters for its separate update.

Pro Tip: Do not use firmware from the Tronxy global website blindly. It is often outdated. Use community-tested builds or the official "Tronxy 3D Printer" Google Drive links (search for their official download portal).

Method 2: The Community Firmware (Marlin 2.1.x for Tronxy Pro)

If you are tech-savvy and want to unlock the printer’s true potential, the community build (often found on GitHub or the "Tronxy 3D Printers" Facebook group) is superior. This is for the STM32 (32-bit) boards only.

Scenario A: 8-bit Motherboard (V5.2 – Rare now)

These boards use a bootloader via Arduino or a programmer. This is advanced. Title: Tronxy XY-2 Pro Firmware Update: The Safe

  1. Download a pre-compiled .hex file for Marlin 1.1.9 or 2.0.
  2. Install Arduino IDE or use avrdude.
  3. Connect via USB ISP (like USBasp) to the 6-pin header.
  4. Advice: If you have a V5.2, upgrade to a 32-bit board before updating firmware.

Part 8: After the Update – Calibration Ritual

You aren't done just because the screen turns on. A firmware wipe resets the EEPROM.

Mandatory post-update steps:

  1. PID Autotune: Heat the bed to 60°C and nozzle to 200°C. Run M303 command via USB or use the LCD menu. Save with M500.
  2. E-Steps Calibration: Mark 120mm of filament, extrude 100mm. Calculate new steps. The default Tronxy XY-2 Pro is usually E93; after update, it might revert to E95.
  3. Mesh Bed Leveling: Run a 5x5 or 9x9 grid. Save to slot 0.
  4. Z-Offset Wizard: Use a piece of paper. Negative values mean moving closer to the bed. (e.g., -1.20mm).

Final Test: Print a 20mm calibration cube. Check the first layer. If it’s inconsistent, your firmware update succeeded, but your Z-offset is wrong—not the firmware's fault.

The Big Warning: Identify Your Board BEFORE You Download

This is the most critical section of this article. If you flash the wrong firmware, you will brick your printer.

Tronxy has silently revised the XY-2 Pro several times. There are currently three major hardware variants. You must open the electronics case (the box underneath the build plate) and visually inspect the motherboard. Check your screen: The XY-2 Pro usually has a 2

Why Update? The "Stock vs. Custom" Debate

Before we flash anything, you need to decide which path to take.

Option A: Official Tronxy Firmware

Option B: Community Marlin Firmware (The Gold Standard)

Critical Warning: Tronxy is notorious for shipping printers with different motherboards (Marlin vs. H32 chips). You must identify your motherboard before proceeding.
