Two Trees Sapphire Pro Firmware Best

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.

Pros:

Cons:

After rigorous testing on three different Sapphire Pro units (one with a glass bed, one with PEI, one with the stock flexible magnetic plate), the absolute best firmware is a custom compiled Marlin 2.1.2 build with Input Shaping and Linear Advance enabled.

Here is exactly what makes this firmware superior for the Sapphire Pro:

⚠️ Do not use random firmware from unverified Facebook groups or file hosts – many are outdated or incorrect.

If you tell me exactly which control board and screen your Sapphire Pro has, I can provide the complete, ready-to-download firmware file name and the exact configuration.h settings to use.

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

Ultimate Guide to the Best Firmware for Two Trees Sapphire Pro two trees sapphire pro firmware best

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 has improved their stock firmware significantly

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. Cons: After rigorous testing on three different Sapphire

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.

Technically, Klipper isn't "firmware" in the traditional sense—it is a Linux application that sends commands to a very lightweight microcontroller firmware (Klipper firmware). However, for the Sapphire Pro, this is arguably the most powerful setup.

Why run Klipper?

The Catch: You need a Raspberry Pi (or an old laptop) to run Klipper. The Sapphire Pro’s Robin Nano board works flawlessly with Klipper, using the generic "STM32F103" config.

The Verdict: The best firmware for tinkerers and remote printing. If you hate recompiling Marlin, get Klipper.

Example: Back up EEPROM on Marlin before flashing:

For most Sapphire Pro users, the best firmware path is:

If you absolutely cannot add a Pi, compile Marlin 2.1.2 with MESH_BED_LEVELING, LIN_ADVANCE, and THERMAL_PROTECTION enabled. Do not use the factory firmware.
