Based on the solution approach by Jens Geisler. r_T = [cos(phi) -sin(phi); sin(phi) cos(phi] * r ; For arc generation, the center of the circle is the axis of rotation and the radius vector is defined from the circle center to the initial position. Each line segment is formed by successive vector rotations. This requires only two cos() and sin() computations to form the rotation matrix for the duration of the entire arc. Error may accumulate from numerical round-off, since all double numbers are single precision on the Arduino. (True double precision will not have round off issues for CNC applications.) 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(). By the time the arc needs to be applied a correction, the planner should have caught up to the lag caused by the initial plan_arc overhead. This is important when there are successive arc motions. */ // Vector rotation matrix values float cos_T = 1 - 0.5 * theta_per_segment * theta_per_segment; // Small angle approximation float sin_T = theta_per_segment; float arc_target[NUM_AXIS]; float sin_Ti; float cos_Ti; float r_axisi; uint16_t i; int8_t count = 0; // Initialize the linear axis arc_target[Z_AXIS] = current_position[Z_AXIS]; // Initialize the extruder axis arc_target[E_AXIS] = current_position[E_AXIS]; float feed_rate = feedrate * feedrate_multiplier / 60 / 100.0; for (i = 1; i < segments; i++) { // Increment (segments-1) if (count < N_ARC_CORRECTION) { // Apply vector rotation matrix to previous r_axis0 / 1 r_axisi = r_axis0 * sin_T + r_axis1 * cos_T; r_axis0 = r_axis0 * cos_T - r_axis1 * sin_T; r_axis1 = r_axisi; count++; } else { // Arc correction to radius vector.
