Assembly

  • Many screws are attached to plastic. Tighten gently. Less force is better.

  • It is better to retighten screws then over tighten and brake the plastic.

  • You will need a Philips screwdriver and Allen keys.

Unpacking

Unpack your parts and inspect them for shipment damage.

_images/sr1-in-carboard-box.jpg

Some SR1 actuators are secured with plastic straps. Unpack the actuators and cut this strap if present.

Actuators

Place the rig upside down on a pair of stands.

Start by loosely attaching the four 20x20 aluminum bars. The last one at 780mm from rear end.

_images/SRD_base_clean_under.png

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:

_images/rig_to_20x20.jpg

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:

Warning

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.

_images/support_to_motor.jpg

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.

_images/support_to_chassi.jpg

Make sure everything is straight and do not bend. Move the linear motors if needed.

Hint

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.

Hint

The lid of the ECU shall face backwards with the USB port on the left.

Electrical

Connect cables between the ECU and the four linear motors. There are four cables to connect.

Attention

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

_images/3d_sides.jpg _images/3d_ports.jpg

This is the right side of the ECU. Ports RF and RR are highlighted in green.

_images/ecu_m_R.jpg

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:

Emergency stop

Connect the emergency stop. The motion system won’t work without it.

If the emergency stop is unconnected, or activated, the software shows error code 13. Connect the emergency stop, twist to release, and reset the system to remove the error code.

Hint

Twist knob to release the emergency stop.

Attention

Connecting the emergency stop is mandatory.

Danger

Never bypass the emergency stop.

Direct drive and EMI

Direct drive wheels tend to emit electro magnetic interference. Keep emergency stop and cables as far away from any direct drive wheels as possible.

Power

Prior to continuing; take this opportunity to attach all other peripherals, such as wheels and pedals, to your rig.

Connect the power:

_images/power.jpg

Connect the USB-cable to the ECU:

Attention

Avoid using a USB-hub. Connect the SIMRIG SR1 directly to the computer.

Finalize the routing and make sure nothing is chafing or getting squeezed.

First startup

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

Attention

The goal is to have the same weight on all linear motors.

It is preferable to assemble your rig with an equal distance between all linear motors. Place the motors in a square. With the center of gravity in the center of all four motors. This will result in equal load and thus better life span. With an equal distance you also get equal amounts of pitch and roll.

On some rigs it is not possible to mount the motors in a perfect square. This is fine. You should however take care to distribute the load as evenly as possible.

When all accessories are installed it is time to adjust the center of gravity. This to ensure maximum user experience. It is also essential for the longevity of the linear motors. Maximum weight including driver and accessories are 175kg. A single linear motor can handle at maximum 50kg of load. Accessories include steering wheel, pedals, seat, and other equipment that adds weight to your rig.

Easiest way to find or check the center of gravity is to start the load estimation tool in SIMRIG Control Center.

Read more about the load estimation tool here.

Move the seat back or forward to get the distribution as even as possible. Sometimes it’s also necessary to move the steering wheel assembly and/or the pedals.
