Had the same,

Colin told me it could be that my rods arent oiled, that the stepper motors are off as pot meters go,
Uhm and the belts that could be to tight or to losse,

I guess thats it,
Owye i also have a fan now on my makerfarm all the time when its on, a 120mm fan, it didnt do this anymore or not as frequent when i got the fan,

Also perhaps try making the mm/s go slower like 40-45mm/s.
