Complete Guide to Two Trees Sapphire Pro Firmware Updates The Two Trees Sapphire Pro is a popular CoreXY 3D printer known for its sturdy linear rails and fast print speeds. However, getting the most out of this machine requires the right firmware. Whether you are troubleshooting bugs, upgrading components, or looking for smoother motion control, updating your firmware is essential.
If you have heavily modified your Sapphire Pro by adding a BLTouch, upgrading to TMC2209 silent stepper drivers, or moving to a direct-drive extruder, standard pre-compiled firmware will not suffice. You will need to compile your own firmware or find a custom fork. GitHubhttps://github.com
While stock firmware works, many users upgrade to a clean, up-to-date version of open-source Marlin firmware. Upgrading Marlin unlocks advanced features like Manual Mesh Bed Leveling, Linear Advance, and better safety features like Thermal Runaway Protection.
Upgrading from the stock firmware to a modern Marlin 2.0 branch (or Klipper) offers significant improvements:
For users looking for a better GUI (Graphical User Interface) with features like real-time flow rate adjustment, third-party community builds are often shared on platforms like GitHub. two trees sapphire pro firmware link
Two Trees Sapphire Pro Firmware Link: Comprehensive Guide and Update Procedures (2026)
Before flashing anything new, use a USB to TTL serial adapter (like FTDI232) to read and save your current firmware via stm32flash command line. If the new firmware link fails, you can revert to the exact factory state.
This usually means the assets folder was not copied to the SD card, or the firmware is for the wrong screen resolution.
: This is a highly recommended build that adds a color GUI to the MKS Robin Nano. It is based on Marlin 2.0.x and fixes common issues like hotend temperature overshoot.

Access to the latest G-code commands and better screen interface layouts. The High-Performance Path: Klipper
Move your compiled firmware files to the root directory of the SD card. For a standard Marlin/MKS update, your card must contain: MksRobinNano.bin (The compiled firmware binary).
Do you have any installed (BLTouch, custom drivers, different extruders)? Are you aiming for stock Marlin or upgrading to Klipper ?
The Two Trees Sapphire Pro uses a microcontroller to control its various components, including the stepper motors, extruder, and heated bed. The firmware is the software that runs on this microcontroller, instructing it on how to control the printer's components. The firmware link refers to the communication protocol used between the firmware and the printer's components. If you have heavily modified your Sapphire Pro
Which are you planning to install? (Stock, Marlin, or Klipper)
Once the update is done, the printer will restart with the new firmware. The file on the SD card will rename itself to Robin_nano.cur if successful. Troubleshooting Firmware Issues
Use a MicroSD card (preferably 8GB or smaller, or a 16GB card formatted to FAT32).
