What is Constant Velocity Contouring?
Many arcs and contours are made from hundreds of small segments. If a motor were to ramp up and down for each segment, a contour would be very slow. Generally, CVC is the process of concatenating many line together and ramping up to speed, doing the lines, then ramping down. Sounds easy, but it can be difficult to decide which lines belong in a smooth movement. The mechanics of the system can have an effect here. Master attempts to look at the angular direction of each line segment and decides if the angle of the present move is sufficiently different from the last direction to include or exclude it from the ramped line. The box labeled “Ramp Ctrl” is the angle (in radians) of the value the angle is compared to. a value of .2 (default) is about 11 degrees and works well for most people. Feel free to lower this value for finer ramping (slower cut) and raise it to make the ramping course( faster cut), but beware of gouging if you raise it too much. This will be improved over time, but cu
