CNC Machine Build : Custom Built Gantry Style Milling Machine : Charlottesville VA

This is our build page for large format 4'x8' gantry style CNC machine we made at Tinkersmiths Makerspace. Powerful NEMA 34 stepper motors makes this thing a total workhorse. Five horse power, 2.KW 220 volt spindle runs from 8000 to 24000 RPM. Custom electronics along with custom post processor coding in the open source Linux CNC software running on a custom made computer. Designing and building motion control systems is a favorite of ours.

Here are some images of the assembly process. Originally built in 2016 this CNC machine is still the heart of our digital fabrication business today.
