Single precision error can accumulate to be greater than * tool precision in some cases. Therefore, arc path correction is implemented. * * Small angle approximation may be used to reduce computation overhead further. This approximation * holds for everything, but very small circles and large MM_PER_ARC_SEGMENT values. In other words, * theta_per_segment would need to be greater than 0.1 rad and N_ARC_CORRECTION would need to be large * to cause an appreciable drift error. N_ARC_CORRECTION~=25 is more than small enough to correct for * numerical drift error. N_ARC_CORRECTION may be on the order a hundred(s) before error becomes an * issue for CNC machines with the single precision Arduino calculations. * * This approximation also allows plan_arc to immediately insert a line segment into the planner * without the initial overhead of computing cos() or sin().
