After I changed my extruder, Please see: [
forums.reprap.org]
my Z axis homing speed drooped to almost 0.
Marlin config was not changed:
//// MOVEMENT SETTINGS
#define NUM_AXIS 4 // The axis order in all axis related arrays is X, Y, Z, E
#define HOMING_FEEDRATE {50*60, 50*60, 4*60, 0} // set the homing speeds (mm/min)
// default settings
#define DEFAULT_AXIS_STEPS_PER_UNIT {49,49.3017,60,456} // default steps per unit for Ultimaker
#define DEFAULT_MAX_FEEDRATE {200, 200, 3, 25} // (mm/sec)
#define DEFAULT_MAX_ACCELERATION {3000,3000,1000,10000} // 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 3000 // X, Y, Z and E max acceleration in mm/s^2 for printing moves
#define DEFAULT_RETRACT_ACCELERATION 3000 // X, Y, Z and E max acceleration in mm/s^2 for retracts
Anyone have a idea what's going on? Thanks
