Description
Oregon Micro Systems MD10A Microstepper Drive Controller Box 4-Axis 10 ustep/step
This is a custom benchtop enclosure housing four Oregon Micro Systems (OMS) MD10A Microstop microstepper drives. Each MD10A module delivers 10 microsteps per full step, providing fine positional resolution for stepper motor motion control. The four drives share a common power supply within the enclosure — including a toroidal transformer and large filter capacitor visible inside — and are individually accessible via labeled DB9 motor connectors on the rear panel.

Applications
The Oregon Micro Systems MD10A is a microstepping drive module from the OMS line of motion control products, designed for use with bipolar or unipolar stepper motors in precision positioning systems. Microstepping drives like the MD10A divide each full motor step into smaller increments — 10 microsteps per step in this case — reducing vibration and improving positional resolution compared to full- or half-step drives. This type of multi-axis controller box is used in laboratory automation, CNC machine tools, optical alignment stages, semiconductor wafer handling, and other applications requiring coordinated multi-axis stepper motion. Typically controlled via a host computer sending step-pulse and direction signals over a parallel interface or dedicated motion control software. OMS products from this era were commonly found in university research labs, industrial automation cells, and scientific instrumentation setups from the 1990s through the 2000s.
This Oregon Micro Systems MD10A 4-Axis Microstepper Controller Box has not been powered up or tested at our facility. The required motor cables and compatible control software are not available to us, so functional testing was not possible. It is being sold as-is. The enclosure and rear-panel connectors appear intact in the photos, and the interior shows the four MD10A drive modules, transformer, and capacitor all present. Please review all photos carefully and contact us with any questions before purchasing.
