// 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.
