Direct Motion, Inc.

Direct Motion has built PC-based CNC and motion control since 1985, on one idea that has not changed: a single PC can run the whole machine, the application, the motion planning and the servo loops, with no separate controller. The idea was patented in 1999. Today it is a Windows PC, a kernel driver running the loops at 20 kHz, DM's own amplifiers and IO boards, and a .NET library that any programmer, in any .NET language, or any AI assistant, can write against.

DM designs its boards in house, has them assembled by contract manufacturers and tests every one before it ships. The same people design the hardware, write the library and answer the support questions.

History


1985	Jim Trounson begins research on a single-processor, PC-based CNC control.
early 1990s	The first systems ship, as knee-mill retrofits, under the name Micro Motion.
1996	DM moves to Southern California and begins selling new mills with its control instead of retrofits.
1998	The CNC software library moves from DOS to Windows.
1999	DM's single-processor control patent is granted.
2003	DM moves from brushed DC servos to brushless AC servos and begins driving high-power spindles.
2005	Production machine tools with DM control reach the market through a machine builder.
2007	DM begins producing automatic tool changers and complete machining centers.
2011	DM's serial-link control, the architecture sold today, is released across that builder's line.
2012	High-resolution multi-turn BiSS encoders are supported.
2013 to 2017	DM designs and sells its own line of vertical machining centers, built with a partner factory and running DM control.
2017	3D solid modeling at the machine ships: the beginning of 4C.
2026	DM moves to Lake Tapps, Washington, and opens its motion control to any machine builder, with the AI-written application in mind.
