Hi,
I have tried to manually adjusting both the switches so that it stops early but that doesn't see to work. On top of that I have noticed that the starting point of the print has also changed both is X&Y direction. Is there a way to reset the starting point?
Cheers!

Hi @ibnul21,
Welcome in here.
There is two issues that can make this ratteling noise, but the noise always come from one of the stepper motors.
The noise is made as the stepper cant move anymore, like hitting a wall and continue until it is "synchronized"..
Happen if the friction is too high or current is too low, in both situations the stepper makes noise.
As there is 6 shafts involved during extruder movement around the bed, thous shafts need lubrication to keep friction as lo as possible. This is number one for such problem, -so periodical lubrication of thous shaft's is important.
You might have another problem, as this seems to occur when homing before start of movement.
In your case, it might be the X home switch that is mounted too close to the hard stop, meaning the stepper have a little too short stoppage distance for deceleration. So the last two or three step is done against the full (hard) stop and making this noise.
This might have happened if the switch have become worn, allowing to move further, -or slightly become loose over the time, also allowing the head further (closer to the hard stop).
Adjusting this switch a little more "from" the wall it's traveling toward might fix this problem.
Note: To me it looks like it is the X stop switch, but might either be the Y switch..
This might be easier to see/observe from above.
(If the screws for the micro switch are loose, be careful -do not to over tightening the two small attaching screws.)
Good luck
Thanks
