Z Axis Endstop doesn‘t stop movement

[nicoch]

My Z axis endstop doesn‘t stop the z axis movement towards home anymore. If I home it I get a loud rattling noise. What are possible issues to look at and what codes are useful for debugging and posting the results here? Thanks!

Hi,myfriend.
Can't z-axis stop?can you provide videos?

[nicoch]

Now it is different. The other axis seem to have problems too now.

The noise was the same for the Z axis, when using G28 command. When I used Simplyfy3D's JogMode to bring z to 0 there was no problems.

Hi,Is this 3D touch?
It may be that the wiring of the limit switch is not connected properly. You can check it.

[nicoch]

yes, it is 3D Touch and wiring seems okay.

Hi,according to the video you provided, the sound sounds like a limit switch failure.
You can check whether a lower limit switch lights up. If it doesn't, you need to replace it.
or you can provide a picrure of Z-axis and y-axis.

It is lit. It is red all the time and when something triggers it it gets a brighter red.
