OpenValence: An Open Stack for Linear-Motion Machines

openvalence.org Visit website

Editorial interest 82/100 Selection signal · not a rating of the site

An open hardware-and-software project for linear-motion machines, with a shared-state protocol, firmware, motion engine, desktop client, and board designs.

Landing page captured for the 2026-10-05 issue.

For: Open-hardware builders and client developers
Worth noticing: The protocol is pre-release; a registry serves as the single source for wire numbers, and firmware must move a real motor before passing bench checks.

Field notes

Phosphor is described as a reference client that builds its pages from settings declared by the hub, so a new machine setting can appear without an app update. The page lists desktop builds for Windows, macOS, and Linux, and says a simulator can be used without attached hardware. Its measured section reports 8 ns quadrature edges during flash activity; that result is presented by the project itself.
