Goes to location, I can see on the web app the height decreasing passing from 0 to - 100 for example and just when it’s there the Z location resets to 0.
I checked the wires on the encoders, nothing seems loose…
Also her is a capture during movement, the position encoders shows 0
So maybe I am to check with a multimeter the signal on the wires?
If that’s the cause, what is the procedure to change them?
I’m very sorry I’m bad with the forum, my last post was automatically closed

So sorry this post can be closed
