2.) Check that the preconfigured axis roles match the actuators connected to the control box.

3.) Confirm the axis assignment.

“Test all platform axis” is not recommended when the actuators are already mounted on the rig.

11. Optional: Import motion profiles #

Add downloaded motion profiles as follows:

1.) Click “Profiles manager” in the “Motion” menu.

2.) Click “Import profile”.

If everything is set up correctly, you can test the platform.

1.) Click “Enable Motion” in the “Motion” menu.

2.) Click “Manual Control”.

3.) Slowly increase the sliders for the main axes. DO NOT use the “Corners” sliders while the actuators are mounted on the rig. Check that the rig can move freely while you test all main axes (roll, pitch and heave).
