I have the kobra 2 max and ever since ive gotten it I have not been able to get it auto level ( I got the printer second hand ) also I am completely new to 3d printing as a whole but whrn i try to auto level it has a popping and grinding noise and visible jerking. It does the same thing whrn it goes to press the button behind the building plate and misses the button I have tried moving it to be centered with the button to no luck I don't know if I am missing something or doing something wrong please any advise is appreciated because again i know nothing about printing haha
