; WARNING!!! - use M83 or M82(exruder absolute mode) according what your slicer generates
M83 ; extruder relative mode

; move back to pause position XYZ

SERVO set up
\\

<code>
#define NUM_SERVOS 1 // Note: Servo index starts with 0 for M280-M282 commands

// (ms) Delay before the next move will start, to give the servo time to reach its target angle.
// 300ms is a good value but you can try less delay.
// If the servo can't reach the requested position, increase it.
#define SERVO_DELAY { 300 }

// Only power servos during movement, otherwise leave off to prevent jitter
#define DEACTIVATE_SERVOS_AFTER_MOVE
