CNC Machine

Shown here is a partially completed prototype of a plotter which was my first attempt at building a machine similar to that shown above. This machine was built from old printers and used a keypad programmable motor controller. The construction of the final machine was facilitated using purchased plans.

The SolidWorks design of the floating nuts for my CNC machine. These pieces allow the driving threaded rods to wobble up/down and side to side, preventing the Lead-screw systems from binding.

The machined floating nut which prevents binding by allowing 2 degrees of translational freedom perpendicular to the leadscrew.

Everything sits on a solid work bench built almost entirely from 4x4 pieces of treated lumber.
