Ultimate Guide to the Best Firmware for Two Trees Sapphire Pro
The Two Trees Sapphire Pro is a beloved "tinker’s" 3D printer. While its CoreXY motion system offers incredible speed potential, the stock firmware often leaves users frustrated with limited features and mediocre print quality.
If you want to unlock the full potential of your machine, upgrading the firmware is the single best modification you can make. 1. Klipper: The Gold Standard for Speed
If you are searching for the absolute "best" in terms of performance, Klipper is the winner. Unlike traditional firmware, Klipper runs on a secondary computer (like a Raspberry Pi) and handles all the complex math there, leaving the printer’s MKS Robin Nano board to simply execute movements. Why it’s the best:
Input Shaper: Virtually eliminates "ghosting" or ringing at high speeds.
Pressure Advance: drastically improves corner quality and reduces oozing.
On-the-fly Config: No need to recompile; you just edit a text file and restart.
The Catch: You need a Raspberry Pi or an old laptop/thin client to run it. 2. Marlin (Custom Builds): The Reliable Classic
For those who want a standalone experience without extra hardware, a custom build of Marlin 2.1.x is the way to go. The stock firmware is a modified, older version of Marlin; moving to a clean, community-optimized build changes everything. Top Community Builds: MKS official GitHub: Stable but basic.
TinyBee/Community Forks: Look for configurations by users like Foxies or TinyTree on GitHub. These are pre-tuned specifically for the Sapphire Pro’s CoreXY kinematics. Key Features to Enable: Linear Advance: Essential for sharp corners. two trees sapphire pro firmware best
S-Curve Acceleration: Smoother movements and less vibration. Babystepping: For perfect first layers. 3. Foxies Marlin: The "Plug and Play" Choice
If you aren't comfortable editing Configuration.h files, the Foxies firmware fork is widely considered the best pre-compiled Marlin version for the Sapphire Pro. It is specifically tuned for the MKS Robin Nano boards used in Two Trees machines.
Best for: Users who want a stable, feature-rich experience without learning how to code.
Highlight: It usually includes a much better UI and better support for BLTouch/3DTouch leveling sensors. Essential Calibration After Flashing
No matter which firmware you choose, you must recalibrate these three things to see a difference:
E-Steps: The stock extruder is known for being slightly off. Calibrate this to ensure you aren't under-extruding.
PID Tuning: Run a PID tune for both the nozzle and the bed to prevent temperature fluctuations.
CoreXY Squaring: Firmware can’t fix a crooked frame. Ensure your belts are tensioned equally. Verdict: Which should you choose?
Choose Klipper if you want to push the Sapphire Pro to 150mm/s+ and don't mind the setup.
Choose Custom Marlin if you want a reliable, "set it and forget it" machine that prints better than stock.
Upgrading your firmware turns the Sapphire Pro from a budget hobbyist machine into a high-speed production tool.
Choosing the "best" firmware for your TwoTrees Sapphire Pro (SP-3) depends on whether you want a stable, easy-to-use experience or peak performance through high-speed printing. 1. Best for Ease of Use: Custom Marlin 2.x
The Sapphire Pro typically ships with an older version of Marlin or a locked-down Makerbase (MKS) firmware. For a significant upgrade without changing your hardware setup, a community-optimized Marlin 2.0.x fork is the gold standard.
Key Features: Enables thermal runaway protection (critical for safety), adds manual/mesh bed leveling, and fixes the notorious "overshoot" issues on the stock hotend. Let’s cut through the noise
Best Version: Look for repositories like the Mks-Robin-Nano-Marlin2.0-Firmware-for-Sapphire-pro which supports the colorful LVGL GUI and touch screen interface.
Installation: Simply download the Robin_nano35.bin file, place it on a FAT32-formatted SD card, and restart the printer. 2. Best for High Performance: Klipper
If you want to push the CoreXY speed of the Sapphire Pro to its limits, Klipper is the superior choice. It offloads heavy processing to a Raspberry Pi (or similar), allowing for "Input Shaping" to eliminate ghosting at high speeds. Two Trees Sapphire Pro, 3D printer custom firmware ⚙️
