​
Overview

These specifications help you plan power, performance, and mechanical modifications for OSSM Ready to Play. Values represent typical performance of a stock unit under normal operating conditions.
Unless otherwise noted, measurements reflect operation with a dedicated 24 V DC, 4 A power supply. Actual performance can vary with payload, friction, alignment, and firmware settings.

​
Electrical

Looking to use a battery to power the OSSM? You’ll want a battery with the following specs: USB-C PD, 65W, 20V
Use a quality 24 V DC power supply rated for at least 4 A to achieve peak performance. Undersized or unstable supplies can cause stalls, reduced force, or controller resets.

Shipping

The Ready-to-Play ships in a plain, unmarked cardboard box with no branding. For more information about our privacy practices, see Discreet Shipping.

​
Storage and Portability

The Ready-to-Play stand folds flat for compact storage—slide it under a bed or into a closet. The unit does not disassemble, but the collapsible design makes it easy to store when not in use.

​
Noise

OSSM uses a nearly silent belt drive system. At low to moderate speeds, the machine operates very quietly. Noise increases at higher speeds but remains reasonable for most environments.

​
Modifications

You can extend the rail length beyond the default configuration to increase stroke length.
Calculate your maximum stroke by subtracting 7 in (180 mm) from your total rail length. For example, an 18 in rail supports a maximum stroke of 11 in.
Extending rail length increases the potential stroke but may also increase bending and friction if not properly supported. Ensure rails are aligned and supported to maintain smooth motion and reduce wear.

​
Upgrading your rail later

If you purchase a Ready to Play with the standard 350mm rail and decide you want more stroke length later, you can upgrade. The rail is designed to be user-replaceable—your R2P includes spare fasteners and Allen keys to support modifications. To order a longer rail:
  1. Contact support@researchanddesire.com with your upgrade request
  2. Specify your preferred rail length (400mm or 500mm are standard stock sizes; other lengths may require additional lead time)
  3. Support will provide pricing and shipping details
Rail replacement is straightforward and doesn’t require specialized tools beyond the Allen keys included with your kit. If you’re unsure about the process, reach out to support or ask in the Kinky Makers Discord.
