Mastering Your Two Trees Sapphire Pro: A Comprehensive Firmware Update Guide

The Two Trees Sapphire Pro is a beast of a CoreXY machine, beloved for its rigid frame and linear rails. However, to truly unlock its potential—or just to fix some out-of-the-box quirks—you’ll eventually need to dive into a firmware update.

Whether you're looking to enable Linear Advance, install a BLTouch, or simply move to a more stable version of Marlin, here is everything you need to know about updating your Sapphire Pro firmware. 1. Why Update the Firmware?

The stock firmware on many Sapphire Pro units is a customized version of Robin Nano firmware. While functional, it often lacks modern features. Updating allows you to: two trees sapphire pro firmware upd

Improve Print Quality: Access features like S-Curve Acceleration and Input Shaping.

Safety First: Ensure Thermal Runaway Protection is active and calibrated.

Hardware Upgrades: Essential if you add a bed leveling sensor or change your stepper drivers (e.g., upgrading to TMC2209s).

Customization: Personalize your touch screen interface and menu options. 2. Identify Your Motherboard

Before downloading any files, you must know what’s under the hood. Two Trees has shipped the Sapphire Pro with different board versions, most commonly: MKS Robin Nano v1.2 MKS Robin Nano v1.3

Open the bottom electronics compartment and check the version number printed directly on the PCB. Using firmware meant for a v1.3 board on a v1.2 board can lead to screen blackouts or non-functional SD ports. 3. Preparation: What You’ll Need

A MicroSD Card: Use a high-quality card (8GB or 16GB is ideal). Format it to FAT32 with a 4096 allocation unit size. Firmware Files: You have two main choices: Official Two Trees Firmware: Safe, but often outdated.

Community Marlin Builds: Highly recommended. Developers like Maksym Bodnar or the Marlin Ultimate community provide pre-configured Sapphire Pro branches on GitHub. Once the main screen loads normally, the update is complete

The "Assets" Folder: If you are using an MKS Robin Nano board, you need the mks_font and mks_pic folders to ensure the touch screen displays icons correctly. 4. The Update Process (Step-by-Step) Step A: Prepare the SD Card

Clean the SD card completely. Drag and drop the following files onto the root directory:

Robin_nano35.bin (Note: The name must be exact; if your board expects elegoo_nano.bin or similar based on a previous flash, match that).

mks_config.txt (This is where you can live-edit settings like steps-per-mm or inverted axes). The assets folder (containing the UI images). Step B: Flash the Machine Turn off your printer.

Insert the MicroSD card into the slot on the printer (not the side of the screen, but the motherboard slot). Turn the printer on.

You should see a progress bar on the screen. Do not turn off the power during this process. It usually takes 30–60 seconds. Step C: Verification

Once the update hits 100%, the printer will reboot into the new interface.

Check the Version: Go to Settings > About to confirm the firmware build date. After any two trees sapphire pro firmware upd

Reset EEPROM: This is crucial. Go to the terminal (via OctoPrint or Pronterface) and send M502 followed by M500, or use the "Reset Factory Settings" option on the touch screen. 5. Post-Update Troubleshooting

Blank Screen? You likely used firmware compiled for the wrong board version or didn't include the assets folder.

Motors Moving Backward? Don't reflash! Open your mks_config.txt file on the SD card, find the INVERT_X_DIR or INVERT_Y_DIR settings, change them from 1 to 0 (or vice-versa), and reboot.

Touch Screen Unresponsive? Ensure the cfg_touch_calibration setting in your config file is set to trigger a calibration on the next boot. Conclusion

Updating the Two Trees Sapphire Pro firmware is the single best "free" upgrade you can give your printer. It transforms the machine from a basic kit into a precision tool. Just remember: Always backup your current mks_config.txt before trying something new!

Avoid random forum links. Start here:

Never flash a file named unknown.bin obtained from a random Google Drive link. Malicious firmware can damage your stepper drivers.

If you own a Two Trees Sapphire Pro laser engraver or CNC router, you know it’s a powerful machine capable of stunning detail and robust cutting.
