I had two MHP machines. MHP = M(oog) H(ydra) P(oint) They ran gcode just like any NC/CNC machine. Each linear axis had two cylinders opposing one another. A hydraulic servo valve released pressure from one or another cylinder to allow the table to move away from the high pressure side. The positioning was high resolution Heidenhain glass scales. Large hydraulic pump beside the machine. Very smooth, very accurate, howling, oily mess. I liked the Moog control panel. It seemed very intuitive and easy to run. I used two machines to keep one running. I would LOVE to have them now with LinuxCNC.
