Unpack your parts and inspect them for shipment damage.
All SR1 actuators are secured with plastic straps. Unpack the actuators and cut this strap.
Place the rig upside down on a pair of stands.
Start by loosely attaching the four 20x20 aluminum bars. The last one at 880mm from rear end.
Each 20x20 aluminum bar is attached to the rig with two 20mm angle brackets. Brake off one alignment pin on each bracket (use a scewdriver.) Place the bracket on the bottom side of the rig. Attach with M5 screws and T-nuts:
With the SIMRIG logo facing outwards; place the linear motors in between the bars and secure them with sixteen M5x25 screws and T-nuts (four for each linear motor.) Do not tighten completely yet. They need to be a loose when assembling the supports.
Tighten the four pieces of 20x20 aluminum bars.
Attach one pad under each linear motor:
Do not run the SIMRIG SR1 without the above pads attached!
Turn the rig around.
Assemble the supports between each linear motor and the rig.
Attach the supports to the rig with two M5/M8 screws and T-nuts. Do not tighten yet.
Attach each support to each linear motor with two M5x25 screws, two washers, two M5 nuts, and two plugs (black plastic spacer.) Do not tighten yet.
Make sure everything is straight and do not bend. Move the linear motors if needed.
Tighten all the screws gently. It is plastic.
Less is more!
It’s better to extra tighten after the rig has been used for period of time than to over tighten.
Electrical Control Unit¶
Place the Electronic Control Unit (ECU) under the seat and attach it to the frame; with th lid of the ECU facing backwards and the power and USB port to the left. Either connect it to the frame with tie straps or screws.
The lid of the ECU shall face backwards with the USB port on the left.
Connect cables between the ECU and the four linear motors. There are four cables to connect.
The linear motors needs to be connected in the correct port of the ECU.
While facing the ECU lid (with the USB port on the left side) make the following connections:
Left Front (LF) motor to upper left port
Left Rear (LR) motor to lower left port
Right Front (RF) motor to upper right port
Right Rear (RR) motor to lower right port
This is the right side of the ECU. Ports RF and RR are highlighted in green.
This is the left side of the ECU. Ports LF and LR are highlighted in green.
The other end of the the cable is connected to the linear motors. The connector is highlighted green:
Connect the emergency stop. Without it the motion will not work.
Make sure it’s not activated (twist to release.)
Prior to continuing; take this oppertunity to attach all other peripherals, such as wheels and pedals, to your rig.
Connect the power:
Connect the USB-cable to the ECU:
Finalize the routing and make sure nothing is chafing or getting squeezed.
On a 60x20 rig it can be necessary to drill holes for the seats brackets. (the M5 nuts in the aluminum profile is a little to small for this task)
Install SIMRIG Control Center.
Make sure that the rig is standing on a flat surface.
The rig can be uneven before it is calibrated – this is normal. The rig calibrates automatically when a car is started within a game (when the motion system receives telemetry from the game.)
When the linear motors are not activated by the game they are temporary tuned off. When the linear motors are turned of the rig can tilt or move because of the weight are not longer supported with help of the motors.
Adjust center of gravity¶
The motors shall preferably be assembled with the same distance between them. And with the driver in the center of the four linear motors. This for best immersion and life span of the motors. Same weight on each linear motor.
When all accessories are installed it’s time to adjust the center of gravity. This to ensure maximum user experience and it’s also essential for the longlivity of the linear motors. Maximum weight including driver and accessories are 175kg. A single linear motor can handle max 50kg. Accessories are steering wheel and pedals and seat and other equipment that adds to the weight that needs to be moved.
The goal is to have the same weight on all linear motors
The ideal procedure would be to have four bathroom scales one under each linear motor. But it’s fine with one scale also. Put the scale under one front linear motor first and a distance of similar height under the other front linear motor. Even better if you have three distances one under each motor. Get into the rig and sit as you would when driving have a other person read the scale. Move the scale and distance height to rear linear motors. The weight should be roughly the same within max 5kg difference. The closer the better. Adjust your seat and pedals and wheel forward or backward if not ok.
