This is the story of me building myOX - my version of the "ideal" OX. I want a machine which can route/mill at least 4' wide and as long as I can feed through (don't be shy, think "infinity") as well as going deep on multiple faces - manual 4th axis. I have loads of ideas to take myOX towards that goal and way beyond. Time will tell. Just follow along through this build and possibly a few others along the way ...

Four Axis Rotary Machine (FARM) OX. Equipped with a X,Z,A & C Axis.

This is an experiment to build a Linear Delta Printer using four towers instead of three. Primary reasons: 1. Build area is roughly cubic vs roughly cylindrical 2. Greater speed and precision from additional control provided by fourth tower. 3. Symmetric kinematics from even number of towers.
