# OSSM Ready-to-Play Info Sheet

> Everything you need to know to get started with your OSSM Ready-to-Play kit, including setup instructions and safety guidelines.

Welcome to your OSSM Ready-to-Play kit. This guide helps you unbox, set up, and use your machine safely and confidently.

## What's in the box

Your accessory box includes:

* OSSM remote and Ethernet cable (or wireless remote, depending on configuration)
* Spare fasteners and Allen keys
* End-effector set (see details below)
* Empty sandbag (counterweight)
* 24V power supply

### Fasteners and hardware

Your kit includes several fasteners. Here's what each is for:

| Fastener                          | Purpose                              | Location                                             |
| --------------------------------- | ------------------------------------ | ---------------------------------------------------- |
| M5 bolt (long, in rear tensioner) | Belt tensioner—keeps belt tight      | Already installed in rear tensioner, or in parts box |
| M5 nut                            | Pairs with belt tensioner bolt       | Rear tensioner or parts box                          |
| Toy adapter screws (2× matching)  | Secure toys to end-effector adapters | Parts box                                            |
| Allen keys                        | Tighten fasteners                    | Parts box                                            |

<Warning>
  The **belt tensioner bolt** is critical. If it's loose in the parts box, you must install it in the rear tensioner before use. Without it, the belt will slip and make a ratcheting noise. See [Verify belt tension](#verify-belt-tension) below.
</Warning>

### End-effector set

The end-effector set includes everything you need to mount a variety of toys:

* **Flange Base** (24mm threaded) and **Dildo Rings** (50mm and 63mm) for securing suction-cup toys and preventing rotation
* **Vac-U-Lock adapter** for toys with Vac-U-Lock sockets
* **3 ft paracord** for tie-on mounting

<Tip>
  For step-by-step instructions on each attachment method, see the <a href="/ossm/Hardware/standard-printed-parts/toy-mounting/introduction">Toy Mounting Guide</a>.
</Tip>

<Note>
  Contents may vary slightly based on your order options. If something is missing, <a href="mailto:support@researchanddesire.com">reach out</a>.
</Note>

## Before you begin

* Choose a stable, flat surface with enough clearance for full stroke length.
* Have clean, playbox-quality sand ready for the counterweight.
* If you have the wireless remote (RADR), charge it via USB‑C before pairing. See <a href="/research-and-desire-remote/quick-start">RADR Quick Start</a>.

<Tip>
  Keep your firmware current for best performance. See <a href="/open-source-sex-machine/flashing-your-ossm">Flashing your OSSM</a>.
</Tip>

## First-time setup

<Steps>
  <Step title="Verify belt tension" id="verify-belt-tension">
    Check that the belt tensioner bolt is installed in the rear tensioner (the end opposite the motor). This M5 bolt threads into a nut inside the tensioner and pushes against the belt pulley to maintain tension.

    * **If the bolt is already installed:** Hand-tighten it by gripping and twisting until firm.
    * **If the bolt is loose in the parts box:** Insert the M5 nut into the rear tensioner slot, then thread the bolt through until it contacts the belt pulley. Hand-tighten until the belt is taut.

    <Warning>
      Without the belt tensioner bolt installed, the belt will slip under load and make a loud ratcheting noise. This is the most common first-use issue.
    </Warning>

    <Check>
      Press the belt with your finger—it should deflect slightly but feel firm. Move the carriage by hand along the rail; it should glide smoothly without the belt slipping.
    </Check>
  </Step>

  <Step title="Fill and place the sandbag counterweight">
    Fill both compartments of the included sandbag with clean, playbox-quality sand and seal fully. Place it so it counterbalances the OSSM and stand during operation.

    <Warning>
      Do not use beach sand. It may contain salt, moisture, and microbes that can cause contamination or corrosion.
    </Warning>
  </Step>

  <Step title="Connect power and controls">
    * Mount and secure the machine to your stand or base.
    * Plug the 24V power supply into the board's barrel jack.
    * If using the wired remote, connect the Ethernet cable firmly at both ends.
    * If using the wireless remote (RADR), power it on and follow the <a href="/research-and-desire-remote/quick-start">RADR Quick Start</a>.
  </Step>

  <Step title="Home and test motion (no load)">
    Power on the OSSM and allow it to complete its homing routine. Keep hands and loose items away from the rail and carriage.

    <Check>
      Confirm the carriage moves smoothly across its range without unusual sounds, binding, or stalls.
    </Check>
  </Step>

  <Step title="Attach a toy securely">
    Use the end-effector hardware and paracord to secure your toy. Verify all knots, clamps, and fasteners are tight and cannot slip under load.

    <Check>
      Gently tug-test the attachment before play. Recheck after the first minute of motion.
    </Check>
  </Step>

  <Step title="Start slow and dial in settings">
    Begin at low speed and short stroke. Gradually increase as you confirm stability and comfort.
  </Step>
</Steps>

## Safety guidelines

### General safety

<Note>
  You are responsible for your setup and safety. If anything is unclear, pause and seek help in the community or <a href="mailto:support@researchanddesire.com">contact support</a>.
</Note>

* Understand how your specific configuration works before play.
* Keep the area tidy and free of cables or objects that could snag.
* Establish a clear stop or safe word/gesture with any partner.

### Electrical safety

* The OSSM operates at 24V. Verify wiring polarity before powering on.
* Keep conductive materials away from the board and power supply.
* Ensure all connectors are fully seated; never insert or remove cables under load.

<Tip>
  Use a high-quality, UL-listed 24V supply and check for firm barrel-jack connection at the board. See the <a href="/open-source-sex-machine/ossm-electronics/ossm-pcb-spec-sheet">PCB Spec Sheet</a>.
</Tip>

### Mechanical safety

<Warning>
  The rail and carriage include pinch points. Keep fingers, hair, clothing, and sensitive areas clear during operation.
</Warning>

* Depending on motor selection, the OSSM can generate significant force. Increase intensity gradually and avoid sudden changes.
* Always maintain the ability to move away from the machine quickly. If playing with a partner, designate a spotter responsible for safety.
* Inspect fasteners, belts, and mounts regularly—tighten as needed.

<Info>
  Using the wireless remote (RADR)? If Bluetooth disconnects during play, the OSSM will ramp down and pause as a safety precaution. For pairing and recovery tips, see <a href="/research-and-desire-remote/quick-start">RADR Quick Start</a>.
</Info>

## Sandbag setup (counterweight)

* Fill both sides with clean, playbox-quality sand.
* Seal completely and place to counterbalance your stand and machine.
* Re-check placement anytime you change height, angle, or stroke length.

<Warning>
  Avoid beach sand due to potential contaminants and moisture.
</Warning>

## Troubleshooting basics

* **Belt slips or makes a ratcheting noise:** The belt tensioner bolt is missing or loose. Locate the M5 bolt (check the parts box if not installed), insert it into the rear tensioner with the nut, and hand-tighten until the belt is firm. See [Verify belt tension](#verify-belt-tension).
* **Toy slides or rotates on the adapter:** Use the toy adapter screws (2× matching screws in the parts box) to secure the toy to the end-effector. For suction-cup toys, use the paracord with the flange ring system. See the <a href="/ossm/Hardware/standard-printed-parts/toy-mounting/introduction">Toy Mounting Guide</a>.
* **No motion after power-on:** Verify 24V supply, barrel jack connection, and that the board is powered. Allow homing to complete before sending motion.
* **Jerky or unexpected motion:** Recheck motor and remote connections; reduce speed/stroke and test again.
* **Remote won't connect:**
  * Wired: reseat Ethernet connectors until they click.
  * Wireless (RADR): charge the remote, power-cycle both devices, and retry pairing using the <a href="/research-and-desire-remote/quick-start">RADR Quick Start</a>.
* **Firmware mismatch or issues:** Update using <a href="/open-source-sex-machine/flashing-your-ossm">Flashing your OSSM</a>.
