CNC Controller Constant Velocity runtime comparison

This is initial testing of various CNC controllers Constant Velocity runtime speed. All controllers set to same parameters for each XYZ axis 200 steps/mm7000mm/min maximum G0 feed rate (275inch/minute)200mm/s^2 acceleration (7.87inch/s^2) All runtimes using the same 10,000 line 3axis continuous motion carving gcode file.
