      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.

      Started by tapping the 5mm holes. I used a tap bought at Harbor Freight and it bent while tapping the extrusion. Lesson: buy quality tools.

      File the ends to ensure each axis are the same length.

      Started assembling wheels and gantry plates. I'm embarrassed to say how many times I messed these up. You can spot many in the photos.

      Slow progress. Things are coming together though.

      I believe these are the screws that were marked 25mm but are only 20mm.

      Wiring, homing switches, and installing the water cooled spindle. I thought after assembling the frame I was almost done, I was wrong.

      Limit switches will eventually be replaced with something better. These have plugs that come out way to easily and could cause problems.

      Update: Made changes to the x-gantry, gives a lower profile and improved ridgitity.

      Replaced the stiff orange water tubing with flexible clear tubing. The orange tube would kink too easily.
