VPX Calibration
To use the PinOne controller with VPX, configure as shown in the picture below:
- Go to Preferences -> Configure Keys, Nudge and DOF

If you want velocity based nudge, turn on velocity output on the accelerometer page and set VPX to read Rx/Ry.
For VPX Plunger calibration, ensure you have the "Plunger quick release" enabled for the best accuracy. You can read about it here.
