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 fork is the gold standard.
Ready to print faster and cleaner than ever before? Grab a Raspberry Pi, flash Klipper, and unleash your Sapphire Pro today.
Before flashing any firmware, you must check the version of your mainboard. Two Trees shipped the Sapphire Pro with different versions of the Makerbase MKS Robin Nano board: two trees sapphire pro firmware best
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 is a custom compiled Marlin 2.1.2 build with Input Shaping and Linear Advance enabled.
If your extruder or axis motors move in the wrong direction, invert the appropriate dir_pin setting. In Marlin, this is done in the configuration file. In Klipper, simply add a ! before the pin number. The Sapphire Pro typically ships with an older
Stable, easy to configure, works directly with the stock screen. Cons: Less advanced motion planning than Klipper. B. Klipper (Best for High Speed & Performance)
The most important resource for the Two Trees Sapphire Pro is the community of users who have tinkered, solved problems, and shared their work. The official manufacturer support may be lacking, but the open-source community is thriving. Grab a Raspberry Pi, flash Klipper, and unleash
If you want, I can produce a ready-to-flash Marlin configuration tailored to the Two Trees Sapphire Pro (including specific steps/mm, thermistor, and board settings) or a Klipper configuration with input shaping — specify which firmware and I’ll provide the configuration files and exact flashing commands.
