Issue with NEMA 17 Stepper Motors and DRV8825 Drivers during Homing

I am facing an issue with my NEMA 17 stepper motors that have a step angle of 0.9° per step. I am using DRV8825 drivers with a microstepping setting of 1/16. During the homing process of all axes, the X-axis gets stuck, and the motor loses steps as it tends to move too quickly. However, when I perform homing for the X-axis only, this problem does not occur. I have checked the current settings and ensured that there are no mechanical obstructions. Can anyone help me identify the possible causes of this issue and suggest potential solutions?

I have attached a video of the problem

It could be due to an electrical field, the motors have magnets in them. Try moving them or use a foil shield.

Check jerk and acceleration settings. If either is too high the motors can miss steps. Also keep in mind using 0.9 degree motors requires 2x the step rate from the driver (compared to 1.8 degree steppers) to achieve the same speed. Watch the temperature of the driver chips. They can overheat easily if you're using tiny modules because the PCB is too small to dissipate much heat. When a driver overheats, it may shut itself down momentarily causing motors to start and stop.
