Do you mean gear rubbing on motor or gear wrong way round 

RE: my senior in my club said that this should not be fixed

it is the wrong way around, it is even in the opposite side

RE: my senior in my club said that this should not be fixed

Well because motor on opposite side it being the wrong way round will be compensated for but certainly would not have it running against motor

RE: my senior in my club said that this should not be fixed

But why not just follow prusa instructions 

RE: my senior in my club said that this should not be fixed

he said that it was not necessary and just leave it be but has been getting x axis error

RE: my senior in my club said that this should not be fixed

Ok the swap motor to other side and swap gear around 

RE: my senior in my club said that this should not be fixed

What letter is before axis does it say y axis x axis or z axis 

RE: my senior in my club said that this should not be fixed

it is saying please check axis length, axis x

RE: my senior in my club said that this should not be fixed

yeah so motor needs swaping to other side 

RE: my senior in my club said that this should not be fixed

alright thanks for your help

really appreciate it

RE: my senior in my club said that this should not be fixed

all good once you do that let me know if its working also make sure gear isn't touch back bit of motor can cause issues later
