Lets see if we can make some distance measurements. (they don't have to be exact but close would be good.)
Can you move the XY and Z Axis using the LCD manually.
Lets start with 2 inches (50.8mm)
Set any start location using masking tape mark the position of the nozzle.
Using the LCD move the nozzle 50.8mm and mark the distance then measure how far it moved.
Is the measured distance and the display distance approximately same.

#define DEFAULT_AXIS_STEPS_PER_UNIT {200, 200, 800, 280 }
?
What stepper drivers do you have fitted ?
How did you come by these settings, X Y steps seem rather high.

I though you already had your configuration.h, asked if you had the three jumpers installed video showed. Should have just posted the Jumper Image.
Prusa calculator is here
And
Triffid Hunter's Calibration Guide
Would Need more information in order give you Default Axis numbers.
Lead screw diameter and Pitch - PITCH (distance of rise for one full rotation)
Belt Pitch and Gear number of teeth
Below I have numbers for all Nema 17 Leadscrew Pitch, a 20 tooth 2mm pitch belt driven Y-Axis and X-Axis for my Prusa Hic i3, and Extruder number
// Typical stepper motors have 200 steps per full step/rev = 1.8°/step, so 1/16 microstepping = STEPS_PER_REVOLUTION_E = 3200
// X-Y Axis 3200, / 20 tooth, / 2mm pitch Belt = 200*16 / 20 / 2 = 80 :: (STEPS_PER_REVOLUTION_X / IDLER_TEETH_X / BELT_PITCH_X)
// Z Axis 3200, / 1.25mm pitch leadscrew = 200*16 /1.25 = 2560 :: (STEPS_PER_REVOLUTION_Z / PITCH_OF_Z_ROD)
// Z Axis 3200, / 2mm pitch leadscrew = 200*16 /2 = 1600 :: (STEPS_PER_REVOLUTION_Z / PITCH_OF_Z_ROD)
// Z Axis 3200, / 4mm pitch leadscrew = 200*16 /4 = 800 :: (STEPS_PER_REVOLUTION_Z / PITCH_OF_Z_ROD)
// Z Axis 3200, / 8mm pitch leadscrew = 200*16 /8 = 400 :: (STEPS_PER_REVOLUTION_Z / PITCH_OF_Z_ROD)
// E-Axis 3200, / (11mm Gear OD * pi) :: (STEPS_PER_REVOLUTION_E * EXTRUDER_GEAR_RATIO / (PINCH_WHEEL_DIAMETER * PI))
//
Example of My Numbers which are a fairly common Prusa i3 number set.
#define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 400, 94.4962144 }
(Though we may have to calculate all numbers if none was provided with Anet A8 kit. unless we find some with the same setup you have)
What is the Anet A8 you have can look see if can find.

When you made changes to:
#define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 400, 94.4962144 }
Did you do a M502 and M500 to get the new values stored in EEPROM? If not... you won't see any changes.
