Best - Two Trees Sapphire Pro Firmware
Since the Two Trees Sapphire Pro (and its siblings, the Plus and Zero) uses an open-source motherboard (typically an MKS Robin Nano), "Best Firmware" is not a single answer. It depends on whether you want stability or advanced features.
Here is a comprehensive guide to the best firmware options for the Two Trees Sapphire Pro.
Troubleshooting Common Firmware Issues
Even the best firmware can hiccup. Here is how to fix common Sapphire Pro problems post-upgrade. two trees sapphire pro firmware best
| Problem | Likely Cause | Solution |
| :--- | :--- | :--- |
| Printer won’t connect to Klipper | Wrong serial port in printer.cfg | Run ls /dev/serial/by-id/* and copy the result into your config. |
| Thermal runaway on boot | Incorrect thermistor type | Set sensor_type: NTC 100K B3950 in the [extruder] section. |
| Layer shifts at high speed | Overloaded stepper current | In Klipper, set run_current: 0.800 (for TMC2209 drivers). |
| BLTouch fails to deploy | Wrong pin mapping | Use control_pin: PC14 for the SKR 1.4 Turbo. |
3. The "Works Out of the Box" Fix: Two Trees Official Update (2023+)
Two Trees eventually listened to the community. In late 2023, they released an updated official firmware (v2.0.x) that fixed thermal runaway and added a 5x5 mesh leveling. Since the Two Trees Sapphire Pro (and its
Pros:
- Zero configuration required.
- Guaranteed not to brick your screen.
- Supports the laser engraving module (if you bought that combo).
Cons:
- No Input Shaping.
- No Linear Advance.
- Still slower than community builds.
The Verdict: This is the best firmware for beginners who just want to print safely without learning VS Code or PlatformIO.
Option B — Klipper (best performance & advanced motion)
Use Klipper if you want better motion control, higher speeds with quality (via input shaping), and easier development tuning via host Raspberry Pi. Zero configuration required
10. Example configuration snippets (conceptual)
- Steps/mm adjustment (Marlin configuration):
- DEFAULT_AXIS_STEPS_PER_UNIT 80, 80, 400, 825 (example values — measure and replace)
- Enabling mesh bed leveling (Marlin):
- #define ENABLED MESH_BED_LEVELING
- #define GRID_MAX_POINTS_X 3
- Klipper input shaper snippet:
- [input_shaper] shaper_type: mzv frequency: 40.0 damping: 0.15
