Feature upgraded processors and better stepper driver support.
Trusted developers in the 3D printing community regularly post updated Marlin .bin files configured specifically for the Sapphire Pro on GitHub. Crucial Configuration Settings for Sapphire Pro
Let's get to the practical part. Upgrading your TwoTrees Sapphire Pro's firmware is a straightforward process once you have the right file.
: 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. two trees sapphire pro firmware best
Klipper has become the gold standard for CoreXY printers like the Sapphire Pro. Unlike traditional firmware, Klipper runs on a secondary computer (like a Raspberry Pi, BigTreeTech CB1, or an old laptop) and dictates precise movements to the printer’s mainboard. Why It’s the Best
Klipper offloads the heavy processing to a secondary computer (like a Raspberry Pi or BigTreeTech CB1). This allows for features like Input Shaper (which eliminates ghosting at high speeds) and Pressure Advance (which perfects corners and retractions).
: Requires additional hardware (Raspberry Pi or similar) and a more complex initial setup. 2. Marlin (Custom Builds): Best for Standalone Reliability Upgrading your TwoTrees Sapphire Pro's firmware is a
If you are searching for the absolute "best" in terms of performance, 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:
Implementing a BLTouch or 3DTouch auto-leveling sensor is one of the most impactful upgrades. In Marlin, you need to uncomment the SPRO_BLTOUCH define in the configuration file. In Klipper, simply add a [bltouch] section to your printer.cfg . Properly configured ABL compensates for bed irregularities and drastically improves first-layer success rates.
Regardless of which firmware you choose, ensure these "Best Practice" settings are applied to your Sapphire Pro: Klipper has become the gold standard for CoreXY
