Ender 3 V2 Auto home not working properly



  • If someone could help me. I have an ender 3 v2 with Bl Touch that was working fine until very recently.
    When I send it to auto home, it touches the X limit switch twice as I think it should and then instead of following its path to the middle, it tries to do it again this time not stopping by giving full pressure to the X limit switch wanting to follow the step in what would be a negative value to the left by at least 15 mm. followed by an unbearable noise for about 5 seconds and stops, does nothing, stops working, gets stranded.
    I have to turn it off to do whatever tests I can think of. The pulley looks new and is not stretched. The stepper motor correctly moves the hotend from 0 to 220 mm and back. Touching the X limit switch with my finger stops the hotend but does not make any noise.
    I hope I have explained my case well. I have everything according to my understanding well I don't know what else to do
    I would appreciate the help.
