OSR2 vs SR6
Multi-Axis Device Comparison
Overview
The OSR2 and SR6 are both open-source multi-axis devices designed by TempestMAx. The OSR2 offers 3 axes of motion while the SR6 doubles that to 6 axes. Both use the TCode protocol and connect via USB serial. This comparison helps you decide how many axes you need.
Feature Comparison
| Feature | OSR2 | SR6 |
|---|---|---|
| Axes | 3 (stroke, pitch, roll) | 6 (stroke, pitch, roll, twist, surge, sway) |
| Servos | 3 | 6 |
| Immersion | High | Maximum |
| Build Complexity | Moderate | High |
| Power Requirements | ~5A PSU | ~10A+ PSU |
| Physical Size | Compact | Larger |
| Noise | Moderate | Moderate–Loud |
| Script Availability | Good (3-axis) | Growing (6-axis) |
| Firmware | TCode | TCode |
| Price (pre-built) | $200–$400 | $400–$800 |
Choose the OSR2 If…
- You want multi-axis at a lower cost and complexity
- 3 axes (stroke + pitch + roll) is enough immersion for you
- You are new to DIY builds and want a simpler first project
- You want more available multi-axis scripts (3-axis is more common)
Choose the SR6 If…
- You want the absolute most immersive experience possible
- You are comfortable with a more complex build and higher cost
- Twist and sway axes matter to you for realism
- You plan to play 6-axis scripts created by top multi-axis scripters
- Budget is not a primary concern
Verdict
The OSR2 is the best entry point into multi-axis. It provides a massive upgrade over single-axis devices at a manageable cost and complexity. The SR6 is for enthusiasts who want the ultimate experience and are willing to invest the time and money. Both are excellent — the question is how deep you want to go.
