OpenBuilds Sphinx 55
20"x20" (500x500) Lead Screw
The OpenBuilds Sphinx Machine is based on the
C-Beam Sphinx by OpenBuilds Member, Kyo.
The Sphinx is a super strong and accurate easy to assemble CNC machine and a favorite here on OpenBuilds. It takes advantage of the inside tracks of the C-Beam linear rail using Xtreme Mini Solid V Wheels and utilizes the top of the rail with full size Xtreme Solid V wheels.
"We would like to thank OpenBuilds community member Kyo for the design efforts put into the awesome machine known as The Sphinx! Many builds have been inspired from it and Kyo took it to the next level with a great video build to accompany his already great electronics setup tutorial videos." -Mark Carew

Please note: There are many different options for controller/driver packages that can be used to control your machine so be sure to explore all the controller options and pick the one that works for your needs.
The board we are using:
CNC xPRO Driver (All in one grbl controller/driver board)
Please see wiring diagram for this machine below
- We use the free SketchUp Make for our CAD (makes the 3D model parts)
- We use the free OpenBuilds CAM plugin/extension for our CAM (Works up the cut lines and makes the GCODE for the parts)
- We use the free OpenBuilds CONTROL for the controller (Allows you to control your machine and sends the design to the machine)
