Sooo.. i replaced X axis set screws .. tightened right up.. my question is.. what is the best process to change Y axis set screws on a belt driven 1510? Reason is i feel like i have the same issue on Y as i had on X .. stuttering.. missing steps .. When X was a mess.. i had issues with consistency and returning to work zero after size check .. calibration came out a lot better after changing X axis grubs.. hoping for same result after changing/tightening Y axis grubs..
