Ender 3x just scratches bed no matter what

  • Just got a new Ender 3x (with glass bed.)
    Was working fine the first day. Now I cant print at all as the extruder just touches/scratches the bed.
    Makes no difference if I adjust the bed height manually with the knobs or using the offset in menu.
    Even if I set the bed height to the lowest possible and leave a huge gap (rather than a papers width,) the extruder still touches the bed when printing. I'm at a loss. please help. thanks.

  • On the left side of you should have a z limit switch, make sure all the cables are connected to it and adjust it so when you're in the lowest position the nozzle is just above the bed (put the bed in the lowest position too and leave a small gap between the nozzle and the bed). You can read more about it here: https://all3dp.com/2/ender-3-pro-z-offset/ Then you can try to level the bed using for example some youtube tutorials like this one: https://www.youtube.com/watch?v=YHP2DfRl-GQ
