Help New linear modules does not go to home

Good day
Installed my new linear modules today firmware updated unfortunately no response touchscreen works well but no response from the Y Z rail does not go to home position.
(The previous modules there everything worked perfectly).
What struck me was that 4 of the modules went very heavy when I slid them in the right place.
The cables are in the right place as with the old modules.
what’s wrong??
