SERVO set up
#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
