1.) click on Motion

2.) Click on “Configure your motion platform”

7. Import Platform Configuration #

Download pre-configured geometry configuration from SimReactor

1.) click on “Import geometry settings from file”

9. Configure your Motion System #

For geting the best experience through various platform sizes, it is important to configure the distances between the actuators which vary between different rigs

1.) Configure the length and width of your actuator distances, as shown in simhub

2.) Navigate to Controllers and choose the COM port the control unit is connected to via USB, in most cases it is shown as “CH340”

10. Verify Axis assignment #

Simhub is asking if all axis are assigned correctly. It is crucial that axis are assigned correctly.

1.) press on Axis assignment

2.) check if pre-configured Axis role is matching with connected actuators to the controller box

  • 1. Front left Actuator
  • 2. Rear left Actuator
  • 3. Rear right Actuator
  • 4. Front right Actuator
  • 5/6 Reserved for upcoming Reactor Seatbelt Tensioner

3.) submit the axis assignment

“Test all platform axis” is not recommended, if actuators are mounted to the rig already

11. Optional Download and importing Motion Profiles from Simreactor #

If interested, you can download preconfigured game profiles that are compatible with Simreactor from our page (WORK IN PROGRESS)

Downloaded Motion Profiles can be added, following these steps:

1.) Press on “Profiles manager” in the “Motion” menu

2.) Press on “Import profile”

2.) Press on “Manual Control”

3.) slowly increase the sliders of the Main Axis, DONT use the sliders for “Corners” if the actuators are mounted on the rig. Make sure that the rig is moving freely testing all Main Axis (roll, pitch, heave)

13. Start Game #

Congratulation, your system is now ready for your favourite games. Some games need additional steps to activate the motion output. Follow instructions on the simhub software.
