I have been playing with the idea of having my first CNC machine for a while. 1st with the C-Beam Plate Maker and later with the more appealing and robust Sphinx 55. They are both nice machines, but i wanted to try do a custom build for my own specs, but have some questions for the community. I wanna try stay at about the same format as the Sphinx 55, using mostly 2060 V-Slot of 500mm, my questions are: Would it work ok to have 1 of the axis belt driven (Y) and the X and Z screw driven? What is the best tool to use to build in 3D the Machine? I tried OnShape but wanted to know if there is a better alternative.
