Homing just barely moves

In easel, when selecting the setup homing, it just moves a millimeter or so, as if all the switches are already triggered. This just started happening so it wasnt the wiring. When I check with a voltmeter it ranges from 4.1 to 4.4vdc, and when I press the trigger it drops to 0.

Any ideas?

With a multimeter i was checking if it has the buzzing sound. Is that what you refer to?

When the i put black to black, red to white. when the switch is not pressed, no sound, when i press, there is sound.

Is there a way to see what the board sees, so when i press it it says ‘on/off’ for each axis?

Thanks, I think there was something loose, it just started working again. Although i have no idea what i changed.
