 *  guidelines for a new optimal plan.
 *
- *  To increase computational efficiency of these guidelines, a set of planner block pointers have been
- *  created to indicate stop-compute points for when the planner guidelines cannot logically make any further
- *  changes or improvements to the plan when in normal operation and new blocks are streamed and added to the
- *  planner buffer. For example, if a subset of sequential blocks in the planner have been planned and are
- *  bracketed by junction velocities at their maximums (or by the first planner block as well), no new block
- *  added to the planner buffer will alter the velocity profiles within them. So we no longer have to compute
- *  them. Or, if a set of sequential blocks from the first block in the planner (or a optimal stop-compute
- *  point) are all accelerating, they are all optimal and can not be altered by a new block added to the
- *  planner buffer, as this will only further increase the plan speed to chronological blocks until a maximum
- *  junction velocity is reached. However, if the operational conditions of the plan changes from infrequently
- *  used feed holds or feedrate overrides, the stop-compute pointers will be reset and the entire plan is
- *  recomputed as stated in the general guidelines.
+ *  To increase computational efficiency of these guidelines:
+ *    1. We keep track of which blocks need calculation (block->flag.recalculate)
+ *    2. We stop the reverse pass on the first block whose entry_speed == max_entry_speed. As soon
+ *       as that happens, there can be no further increases (ensured by the previous recalculate)
+ *    3. On the forward pass we skip through to the first block with a modified exit speed
+ *       (next->entry_speed)
+ *    4. On the forward pass if we encounter a full acceleration block that limits its exit speed
+ *       (next->entry_speed) we also update the maximum for that junction (next->max_entry_speed)
+ *       so it's never updated again
+ *    5. We use speed squared (ex: entry_speed_sqr in mm^2/s^2) in acceleration limit computations
+ *    6. We don't recompute sqrt(entry_speed_sqr) if the block's entry speed didn't change

 *  - block_buffer_tail: Points to the beginning of the planner buffer. First to be executed or being executed.
 *  - block_buffer_head: Points to the buffer block after the last block in the buffer. Used to indicate whether
 *      the buffer is full or empty. As described for standard ring buffers, this block is always empty.
- *  - block_buffer_planned: Points to the first buffer block after the last optimally planned block for normal
- *      streaming operating conditions. Use for planning optimizations by avoiding recomputing parts of the

Mihail Dumitrescu	0f489c6584	PR27035 Smoother motion by fixing calculating trapezoids and ISR stepping. Fix rounding directions in calculate_trapezoid_for_block(). Fix off-by-ones errors in ac/deceleration steps in block_phase_isr. Half-initialize ac/deceleration_time to smooth the speed change shock that happens between segments, which is critical as jerk/deviation adds to this. The result is a smoother motion profile that follows the imposed acceleration limits with a well defined 0.5-1.5x error factor (or 2x if axis is starting from ~0). Errors are due to converting a real-valued motion profile into discrete numbers of steps. Fixes are general and improve S_CURVE_ACCELERATION too (no endorsement implied). Tested by looking at the generated step/dir impulses with a logic analyzer. Enjoy the smoother motion or use more aggresive acceleration/jerk/deviation values for faster prints. Also improves: #12491 Remove nominal_length, remove MINIMAL_STEP_RATE, add min_entry_speed_sqr, initial clean up of reverse_pass_kernel and forward_pass_kernel. Removing MINIMAL_STEP_RATE allows for correct handling of moves with low acceleration, including fixing judder that's caused when the planner computes an entry speed based on minimum_planner_speed_sqr that's then promptly overriden by MINIMAL_STEP_RATE. Added min_entry_speed_sqr to avoid a specific potential source of judder due to working with discrete steps rather continuous real-valued physics. The first step of any segment runs at initial_rate. If it is too low compared to acceleration_steps_per_s2 it will result in too much accumulated acceleration_time (see stepper.cpp) which will mean the following step will be at a much higher speed, and the speed change will significantly surpass the set acceleration_steps_per_s2 limit. Making sure we can match this limit is why we have minimum_planner_speed_sqr in the first place. Optimal number of sqrts and trapezoid calculations. Remove forward_pass(). Call forward_pass_kernel() from recalculate() instead. Fix potential for large speed changes if planner falls behind. group for clarity and review as described combined float sq match modified names Optimal number of sqrts and trapezoid calculations. Remove forward_pass(). Call forward_pass_kernel() from recalculate() instead. Fix potential for large speed changes if planner falls behind. Save and use block->steps_per_mm to avoid many divisions.	2024-05-28 14:10:46 -04:00
