Two Trees Sapphire Pro Firmware Best Upd May 2026
For the Two Trees Sapphire Pro (SP-3), the "best" firmware depends on whether you value a simple touchscreen interface or high-speed performance through advanced features like Input Shaping. 1. Klipper: The Performance Choice
Klipper is widely considered the best overall upgrade for the Sapphire Pro because it offloads heavy calculations to a secondary device (like a Raspberry Pi), allowing the printer to reach its mechanical limits. Key Benefits:
Enables high speeds (up to 250mm/s+) and accelerations (up to 10k) while maintaining quality through Input Shaping
Users looking to "full send" their machine and who are comfortable with more technical setup. Requires a host device running Linux and a custom printer.cfg for the MKS Robin Nano board. 2. Custom Marlin 2.x: The Reliable Standard
Since the stock firmware is often limited, community-maintained Marlin builds are the go-to for a "plug and play" feel with unlocked features. two trees sapphire pro firmware best

Here’s a solid, informative text about Two Trees Sapphire Pro firmware, covering the best options, their strengths, and key recommendations.
Conclusion: Which Firmware is Truly Best?
Let’s cut through the noise.
- If you are a beginner: Use the official 2023 Two Trees update. It is safe and stable.
- If you want high speed with zero Raspberry Pi hassle: Use the Community Marlin 2.1.x with Input Shaping. This is the "best" for 95% of users.
- If you have a Raspberry Pi collecting dust: Install Klipper. It turns the Sapphire Pro into a Voron-level performer.
For the average user searching for "two trees sapphire pro firmware best," the answer is unequivocally the Insanity Automation fork of Marlin 2.1.x. For the Two Trees Sapphire Pro (SP-3), the
It transforms the Sapphire Pro from a quirky Chinese printer into a precision machine that rivals printers twice its price. You will finally unlock the true potential of the dual Z-axis linear rails. You will print at 90mm/s with the quality of 50mm/s. You will stop fighting your printer and start creating.
Action Step: Do not just download the first .bin file you find. Join the "Two Trees 3D Printers" Discord or the r/TwoTrees subreddit. Look for the pinned messages in the #Sapphire-Pro channel for the most recent, verified "best" firmware build as of this month. Your Sapphire Pro is a race car on blocks right now—the best firmware is the key to the ignition.
Update your firmware today, run a PID tune, print a Benchy at 100mm/s, and watch the magic happen.
5. Installation and flashing procedure (robust, step-by-step)
- Identify board and MCU (e.g., STM32F1/F4) and current firmware type.
- Download matching firmware build (official or compiled from source) and verify checksums.
- Backup current configuration and EEPROM (M503 and save file).
- Put board in bootloader/DFU mode if required (follow board-specific steps).
- Flash using recommended tool:
- STM32CubeProgrammer or DFU for STM32 boards.
- Drag-and-drop BIN on SD for boards that support it.
- For Klipper: install Klipper on host (Raspberry Pi) and flash MCU via make flash.
- Reboot and verify connectivity. Run M115 (Marlin) or check Klipper status.
- Restore EEPROM settings if needed (M500 restore) or reconfigure via firmware config files.
- Run initial tests: stepper movement, endstops, temperature readings, heaters.
The "Pro" Specific Optimizations
The Sapphire Pro has a specific hardware quirk: The stock extruder motor runs hot, and the cooling fan duct is mediocre. The best firmware builds address this by: Conclusion: Which Firmware is Truly Best
- Adjusting the TMC2209 StealthChop threshold: Higher than stock, reducing motor whine.
- Custom PID tuning values: The bed is 220mm x 220mm but thick. The default PID values cause 3-degree swings. The community firmware uses a specific
PID_C value of 40 for the bed.
- Hybrid Threshold: Switches from StealthChop to SpreadCycle at 60mm/s for the XY axes to prevent layer shifts during fast travel moves.
Why choose this?
- Safety: Properly configured Thermal Runaway Protection.
- TFT Support: The Sapphire Pro uses a TFT screen (Touch/Serial mode). Modern Marlin handles the serial commands better than the stock firmware.
- Drivers: Supports the TMC2225 (UART) or TMC2209 drivers usually found in these machines.
Where to Download the Best Firmware Files
Do NOT use random files from Facebook groups. Stick to verified sources:
- TwoTrees Official GitHub: Contains base Marlin and Klipper examples.
- Klipper3D.org: Main Klipper documentation.
- MainsailOS: Pre-packaged Raspberry Pi image with Klipper+Mainsail.
Why "Stock" Firmware is Not the Answer
Before we hunt for the "best," we must understand why you are searching for new firmware in the first place. Two Trees ships the Sapphire Pro with a customized, stripped-down version of Marlin 1.x or an early buggy version of Marlin 2.0 (depending on when you bought the machine).
The stock firmware suffers from:
- Lack of Thermal Runaway Protection: Early versions famously had this disabled.
- No Linear Advance: Essential for sharp corners and consistent extrusion.
- Crippled SD Card Support: Long file names crash the printer.
- Limited Mesh Bed Leveling: The 4x4 grid is insufficient for warped beds.
Upgrading the firmware isn't just about new features; it is about safety and reliability.
Why choose this?
- Input Shaping: The Sapphire Pro is a CoreXY machine with a rigid frame. It is physically capable of high speeds, but stock Marlin struggles to calculate steps fast enough. Klipper offloads math to a Raspberry Pi, allowing for smoother, faster printing.
- Pressure Advance: Eliminates blobbing at corners (a common issue with Bowden setups).
- Web Interface: You get Mainsail or Fluidd to control the printer via your browser.
