// Ensure Smooth Moves
//
// Enable this option to prevent the machine from stuttering when printing multiple short segments.
// This feature uses two strategies to eliminate stuttering:
//
// 1. During short segments a Graphical LCD update may take so much time that the planner buffer gets
// completely drained. When this happens pauses are introduced between short segments, and print moves
// will become jerky until a longer segment provides enough time for the buffer to be filled again.
// This jerkiness negatively affects print quality. The ENSURE_SMOOTH_MOVES option addresses the issue
// by pausing the LCD until there's enough time to safely update.
//
// NOTE: This will cause the Info Screen to lag and controller buttons may become unresponsive.
// Enable ALWAYS_ALLOW_MENU to keep the controller responsive.
//
// 2. No block is allowed to take less time than MIN_BLOCK_TIME. That's the time it takes in the main
// loop to add a new block to the buffer, check temperatures, etc., including all blocked time due to
// interrupts (without LCD update). By enforcing a minimum time-per-move, the buffer is prevented from
// draining.
//
//#define ENSURE_SMOOTH_MOVES
#if ENABLED(ENSURE_SMOOTH_MOVES)
//#define ALWAYS_ALLOW_MENU // If enabled, the menu will always be responsive.
// WARNING: Menu navigation during short moves may cause stuttering!
#define LCD_UPDATE_THRESHOLD 170 // (ms) Minimum duration for the current segment to allow an LCD update.
// Default value is good for graphical LCDs (e.g., REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER).
