Grinding At When homing xtool pro 1 20w

My xtool firmware is y40.31.004.31.B3 the most current per Xtool did a software for Lighburn today to 1.3.00 now every time I home I get a grinding noise I have also reduced my grid size to solve but to no avail. Please Help.

The update may be a coincident. Loosen the belt on one axis and home, than do the same with the other. If the noise changes you can at least narrow down the problem

nope no change
