Two Trees Sapphire Pro Firmware Link Repack -
Once complete, the printer will boot into the new interface. The bootloader automatically renames the file on your SD card to a .CUR extension (e.g., Robin_nano.cur ) to prevent it from reflashing on the next reboot. Troubleshooting Common Firmware Flashing Issues
The official Klipper GitHub repository contains a reference configuration file for this printer. Look under klipper/config/printer-twotrees-sapphire-pro.cfg .
Use the Raspberry Pi imager and select “Mainsail OS.” Then copy the above config file.
This report is limited to an analysis of the Two Trees Sapphire Pro firmware link and does not cover other aspects of the printer's performance or functionality.
Even with careful preparation, issues can arise. Here are some common problems and solutions: two trees sapphire pro firmware link
This is the go-to for a balanced, polished experience, especially if you prefer using the printer's touchscreen.
(also known as the SP-3) generally involves using the official TwoTrees Firmware Download page or community-developed Marlin builds. Because this printer uses an MKS Robin Nano motherboard, the update process is typically handled via a microSD card.
The Sapphire Pro typically ships with a Makerbase MKS Robin Nano motherboard (usually version 1.1 or 1.2 in older batches, or version 1.3/2.0 in later productions). The stock firmware is based on a customized version of Marlin or Robin Nano's proprietary interface.
Depending on what you are flashing, copy the required files to the root directory of the SD card. Once complete, the printer will boot into the new interface
Because the Sapphire Pro uses rigid linear rails, its mechanical chassis can handle incredibly high speeds. Marlin can sometimes bottleneck the processing power of the 32-bit MKS Robin Nano board during complex curves. Klipper offloads the computation to a Raspberry Pi or alternative single-board computer.
: The repository Mks-Robin-Nano-Marlin2.0-Firmware-Sapphire-PRO is a foundational project. Based on Marlin 2.0.x, it adds a colorful GUI and was a starting point for many users. The author notes that this is an old version and points to his newer Marlin project for better UI and functionality.
Ensure these files sit on the root directory and are not hidden inside a subfolder. Step 3: Flash the Printer Turn off your Two Trees Sapphire Pro. Insert the MicroSD card into the motherboard slot. Power on the printer.
The Two Trees Sapphire Pro is a powerful, budget-friendly CoreXY 3D printer loved by enthusiasts for its linear rails and sturdy frame. However, its stock firmware often leaves a lot to be desired in terms of safety, print quality, and advanced features. Upgrading or restoring your firmware is the single best way to unlock the true potential of this machine. Look under klipper/config/printer-twotrees-sapphire-pro
When you visit the official firmware link, you will see several .bin files. Here’s what they mean:
robin_nano_config.txt (The configuration text file containing steps-per-mm and machine limits).
Once you have the correct and downloaded the .bin file, follow this guide:
The Sapphire Pro historically ships with the motherboard (usually version 1.1 or 1.2 in older batches, or version 1.3/2.0 in later runs). Official Download Link
