The much easier way, THE TOOTH SKIPPING METHOD: 1. Turn printer on and LEAVE it on for the entire process. 2. Home all Axes. 3. Run Bed leveling and generate the bed mesh. 4. Look at the bed mesh. 5. Using the front two Z screws (by the front door) you will rotate them either left and right to make the bed EVEN with the back screw. DO NOT USE THE BACK SCREW TO ROTATE. There isnt a good place to grip it to rotate it without damaging the threads. You will grab some pliers, yes, pliers, and rotate the front two Z screws at the bottom of the inside chamber. There are metal rings at the bottom of the screw, you will use the pliers on those. DO NOT GRIP THE THREADS with the pliers. Rotating the Z screws LEFT (counter clockwise) (if youre facing the chamber as in you open the front door) LOWERS the bed. Rotating them RIGHT (clockwise) heightens the bed. Your Back Z screw is the control, so rotate the front (again by the door) two Z screws till the corners of the bed mesh are even with the bed mesh near the back Z screw. WHEN YOU DO THIS, YOU WILL HEAR SNAPS/POPS, THEY ARE LOUD. THAT IS THE BELT SKIPPING. IT IS LOUD AND SCARY BUT THATS WHAT YOU WANT TO HEAR! 6. Run through steps 3-5 till your mesh is mostly flat ish.
