Nema motor stop or/ dosesn't move by force

[akashgajinkar]

Sir my Nema Motor used to work with Shield v3 but now when I connect the USB to a laptop my Nema Motor stops with force and does not move it takes 11.83v with 0.188 amp and it does not move,

I checked the resistance of the NEMA motor and its 55 ohms

Does it mean that my motors are damaged?

But when I manually turn the shaft of my nema motor without connection I can feel shocked on my tongue, and even if I short two wires of winding I can feel the drag and resist of the shaft.

what might be the problem

For the first few days my homemade CNC worked Funtastic with Limit Switch Enabled for All 3 Axis, but things started to give Problems while setting Homing and Soft Limits,
Now Currently During USB is plugged In ALL 3 NEMA Motors Stop By Force taking 0.06Amp to 0.18Amp and It doesn't Move,

My thinking is that My Motor has a rating of 1.2 amp and am using drv8825 so I had set Veff to 0.60 and due to this while homing it uses its full power to move all 3 axis and this might cause the issue,

My code are during starting

Hi, just a simple test to check if it is a nema problem.
Remove the stepper from the system and test it on something else with step/dir signals.
Or change the stepper for a spare one.

If it's not the problem you can focus on the software and controller.
