Added DEFAULT_TRAVEL_ACCELERATION

Marlin/example_configurations/Felix/Configuration.h

 #define DEFAULT_MAX_ACCELERATION      {5000,5000,100,80000}    // X, Y, Z, E maximum start speed for accelerated moves. E default values are good for skeinforge 40+, for older versions raise them a lot.
 
 #define DEFAULT_ACCELERATION          1750 //1500    // X, Y, Z and E max acceleration in mm/s^2 for printing moves
-#define DEFAULT_RETRACT_ACCELERATION  5000   // X, Y, Z and E max acceleration in mm/s^2 for r retracts
+#define DEFAULT_RETRACT_ACCELERATION  5000 // X, Y, Z and E max acceleration in mm/s^2 for r retracts
+#define DEFAULT_TRAVEL_ACCELERATION   3000 // X, Y, Z acceleration in mm/s^2 for travel (non printing) moves
 
 // Offset of the extruders (uncomment if using more than one and relying on firmware to position when changing).
 // The offset has to be X=0, Y=0 for the extruder 0 hotend (default extruder).
