Software built by a machinist, not a software company.

CNCGuy makes tools for the people who actually run the machines. Every one exists because a real job needed it — not because a product team drew it on a whiteboard.

Who's behind it

I'm Bob Foster. I've spent 45+ years on the shop floor — I started on a band saw in a Houston tubular-products shop in 1981, talked my way onto the CNC nobody else would touch, and never looked back. Since then I've programmed mills, lathes, and multi-axis machines, set up cells, maintained AS9100 compliance, and trained more machinists and programmers than I can count, most of that in aerospace.

Along the way I taught myself to code — Visual Basic, C++, Python — and built small tools to make my own jobs easier. Enough machinists asked for them that CNCGuy became the plan: useful, affordable software for the trade, built by someone who's stood at the control.

The rule everything ships under

If it doesn't work on the shop floor, it doesn't ship.

That's why the products lead with what they don't do yet, why pricing will never be the thousand-dollar-a-seat kind, and why nothing phones home. The tools should earn their place on your machine.
