Seems like a simple build and I really like the use of MDF board for rigidity. I am currently looking for ideas to build my own CNC router setup and this one impresses me with the C beams.
SkyKae sphinx - c beam xl hybrid
Build in 'Cartesian Style CNC' published by ChadRat6458, Oct 13, 2017.
I took what I thought were the best parts of the sphinx and the c beam xl to build a bigger and faster machine.
