| Parameter | Recommended Value | |-----------|------------------| | Bed size | X: 240, Y: 240, Z: 250 (or 260) | | Probe offset (BLTouch) | Depends on mount | | Max feedrate (X/Y) | 300 mm/s | | Max acceleration | 1000 mm/s² | | PID autotune | Run for bed & hotend |
Run:

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.
For speed, quality, and remote control, Klipper is the undisputed best firmware for the Sapphire Pro. two trees sapphire pro firmware best
Why it’s superior:
Hardware needed: Raspberry Pi (2B+, 3A+, 3B+, 4B) or a Pi Zero 2W (though a Pi 3B+ is safer). Or a BTT Pi.
Best config source:
Official Klipper printer configs include printer-two-trees-sapphire-pro-2022.cfg (for the newer MKS Robin Nano V3.0 with TMC2209 UART) or community variants for V1.3/V2.0. Check Klipper’s GitHub repo under config/. The best firmware includes a test pattern generator
Common gotchas:
Verdict: Best for users willing to add a Pi. Turns the Sapphire Pro into a 2x–3x faster machine with better quality.
Use Klipper if you want better motion control, higher speeds with quality (via input shaping), and easier development tuning via host Raspberry Pi. Hardware needed: Raspberry Pi (2B+, 3A+, 3B+, 4B)
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.
Firmware is the software that controls your 3D printer's functions. It dictates how the printer interprets G-code, manages its components, and interacts with you. Upgrading or changing your firmware can significantly enhance your printer's capabilities, offering improvements such as:
