- Update grbl version and settings version to automatically reset eeprom. FYI, this will reset your grbl settings. - Saved 3*BLOCK_BUFFER_SIZE doubles in static memory by removing obsolete variables: speed_x, speed_y, and speed_z. - Increased buffer size conservatively to 18 from 16. (Probably can do 20). - Removed expensive! modulo operator from block indexing function. Reduces significant computational overhead. - Re-organized some sqrt() calls to be more efficient during time critical planning cases, rather than non-time critical. - Minor bug fix in planner max junction velocity logic. - Simplified arc logic and removed need to multiply for CW or CCW direction.
