Two Trees Sapphire Pro , the "best" firmware depends on whether you want a stable, easy-to-install experience or high-performance speeds. Top Firmware Options
Klipper (Recommended for Performance): This is widely considered the best choice for this printer's CoreXY motion system. It offloads complex math to a host like a Raspberry Pi, allowing for faster print speeds (up to 500mm/s) and features like Input Shaping to eliminate ringing and Pressure Advance for sharper corners.
Marlin 2.x (Recommended for Stability): The standard open-source alternative to the closed-source stock firmware. It is reliable and easier to set up for beginners since it doesn't require a separate host device. Community forks, such as those by quentinDeroo and l3tspeak, fix stock issues like hotend temperature overshoots and incorrect bed dimensions.
Custom Marlin with GUI: Some community members have ported Marlin specifically to support the original MKS Robin Nano touchscreen interface, providing a more polished "factory-like" feel with open-source benefits. Key Benefits of Upgrading Two Trees Sapphire Pro, 3D printer custom firmware ⚙️
Choosing the "best" firmware for your TwoTrees Sapphire Pro (SP-3)
depends on whether you value high-speed performance or simple, standalone stability 1. Best Overall Performance: Klipper
For users looking to push their CoreXY machine to its limits,
is widely considered the best choice in 2026. It offloads complex calculations to a more powerful host like a Raspberry Pi, enabling much higher print speeds without losing quality. Key Features
: Superior web interfaces (Mainsail/Fluidd), Input Shaping to eliminate ghosting, and "Pressure Advance" for cleaner corners.
: Speed enthusiasts and those comfortable with a bit of technical setup. : Find pre-configured files on Travis90x’s GitHub for the Robin Nano board. 2. Best for Stability & Ease of Use: Marlin 2.0.x
If you prefer your printer to be a standalone tool without needing an external computer, a custom Marlin 2.0.x build is your best bet. Key Features
: Reliable "set and forget" performance and a familiar touch interface. two trees sapphire pro firmware best
: Users who want a solid, stable experience with minimal troubleshooting. Community Versions RolfZuckowskiUltras Marlin

Two Trees Sapphire Pro (SP-3) , the "best" firmware depends on whether you value ease of use or high-speed performance. Most users upgrade from the stock software to either a custom Marlin build or Klipper to unlock features like Linear Advance Input Shaping , and better thermal safety. 1. Klipper: The Performance Choice
Klipper is widely considered the best overall upgrade for the Sapphire Pro because it leverages a host computer (like a Raspberry Pi ) to handle complex calculations. Why it’s best:
It enables much higher print speeds (up to 250mm/s+) and better quality through features like Input Shaping Pressure Advance
. Configuration is "live," meaning you edit a text file instead of re-flashing the board for every change. The Trade-off:
The stock touchscreen will typically become blank or non-functional unless you use a workaround like KlipperScreen on a separate display. You must compile the firmware for the
(standard for the MKS Robin Nano v1.2 board) and use a specific script ( update_mks_robin.py ) to rename the binary so the board recognizes it. 2. Marlin (Custom Builds): The Balanced Choice Two Trees Sapphire Pro , the "best" firmware
If you prefer a standalone printer and want to keep using the built-in touchscreen, a custom Marlin 2.0+ build is the best path. What is the difference between Marlin and Klipper firmware?
Choosing the "best" firmware for your Two Trees Sapphire Pro
depends on whether you value out-of-the-box simplicity or high-performance optimization. While the stock firmware is functional, it is widely considered conservative and lacks advanced quality-of-life features 1. Klipper: Best for Performance & Quality of Life
Klipper is frequently cited as the single biggest "quality of life" upgrade for this machine. It offloads complex calculations to a secondary host like a Raspberry Pi, allowing the Sapphire Pro's CoreXY motion system to shine. Key Benefits Input Shaping Pressure Advance to eliminate ghosting at high speeds (up to 250mm/s+). Ease of Configuration
: Unlike Marlin, you can edit your printer settings in a simple text file without recompiling and reflashing the board every time.
: Requires additional hardware (Raspberry Pi or similar) and a more complex initial setup. 2. Marlin (Custom Builds): Best for Standalone Reliability
If you prefer not to use an external computer, a custom build of Marlin 2.1.x is the preferred choice over stock. What is the difference between Marlin and Klipper firmware?
The "best" firmware for your TwoTrees Sapphire Pro generally depends on whether you value ease of setup or maximum performance. Since this machine is a CoreXY printer with linear rails, it is particularly well-suited for high-speed firmware like Klipper Top Recommendations Klipper (Best for Performance): Most users consider the ultimate upgrade for the Sapphire Pro
It offloads heavy calculations to a separate host (like a Raspberry Pi), allowing for much higher speeds and better print quality through features like Input Shaping Pressure Advance Ease of Use:
You can edit your configuration via a web interface (Mainsail or Fluidd) without re-flashing the board every time. Marlin 2.0+ (Best for Simplicity):
If you want a traditional "flash and forget" experience without extra hardware, custom Marlin 2.0 builds are the standard. Step 4: The Print
It is highly stable and works directly on the original MKS Robin Nano board. Custom Builds: Community-maintained versions, such as those by , often include pre-configured settings for the Sapphire Pro 's specific geometry and UI Custom Hybrids:
Some users prefer specific custom firmware that combines the original TwoTrees UI with Flying Bear features for a simpler, "cleaner" menu system that supports manual leveling and material detection. Key Comparisons Two Trees Sapphire Pro, 3D printer custom firmware ⚙️
For the Two Trees Sapphire Pro (SP-3), the "best" firmware depends on whether you value out-of-the-box simplicity or high-performance speed. For most users, Klipper is widely considered the ultimate upgrade for quality of life and speed. However, customized Marlin builds remain the standard for those who prefer standalone operation without extra hardware. Top Firmware Recommendations

This is where you find the “best” configuration. Download the community-optimized printer.cfg from the TwoTrees Official GitHub or Frix-x’s Klipper config collection. Specifically look for:
The best firmware includes a test pattern generator. Print the "Ringing Tower" at speeds from 40mm/s to 120mm/s. Measure the ringing frequency and set M593 accordingly.
M593 P "zv" F20 (ZV shaper at 20Hz). This eliminates 90% of ringing.For users who want a simple, standalone printer without a Raspberry Pi, a custom-compiled Marlin build is best. Look for builds specifically configured for the Sapphire Pro’s BTT SKR 1.4 or 1.4 Turbo board (common in later models).
Best Marlin Build: The “BigTreeTech Official” or “Sebaz” community builds.
Two Trees has improved their stock firmware significantly over the years. If you purchase a newer unit, you might find that the stock firmware is perfectly adequate for general printing.
