This is a quick build of a CNC Router made with 3 1000mm C-Beams for the X/Y axis and a 250mm C-Beam for the Z Axis. Moving each axis are Nema 23 High Torque series stepper motor. A 24v power suppply and a TinyG controller board will power the machine.

Receiving the packages from OpenBuilds. Everything was well packaged and marked to indicate the contents of the package. Only problem was that a package marked 25mm screws were actually 20mm.
