Reread what I wrote.
An important aspect of the macros is to reduce the current supplied to the steppers which reduces the torque exerted by them.
Secondly, start at 128 and follow the instructions. In my own printers, the SGTHRS values are generally around 60 and 70.
The sensitivity value really isn’t very intuitive and you can’t put in what you think is a best guess.
Reduce the current to the motors and then run the homing macros, starting with your X axis first.
Good luck!
