- Significant improvements in the planner. Removed or reordered repetitive and expensive calculations by order of importance: recalculating unchanged blocks, trig functions [sin(), cos(), tan()], sqrt(), divides, and multiplications. Blocks long enough for nominal speed to be guaranteed to be reached ignored by planner. Done by introducing two uint8_t flags per block. Reduced computational overhead by an order of magnitude. - Arc motion generation completely re-written and optimized. Now runs with acceleration planner. Removed all but one trig function (atan2) from initialization. Streamlined computations. Segment target locations generated by vector transformation and small angle approximation. Arc path correction implemented for accumulated error of approximation and single precision calculation of Arduino. Bug fix in message passing.
