    I'm new to 3D printing, mine keeps thinking point 1 thats supposed to be in the middle of the bed is in the bottom left and point 2 thats supposed to be in the bottom left is far off the board. Mine made a similar noise to yours twice and I didnt turn it off because I wasnt sure what to do. Based on the other comments have i destroyed something? It seems like the 3D printers idea of where the center of the bed is, is messed up and its messing up the other 4 points but i dont know how to fix this. I have a Ender 3 s1 pro, i know thats not the model in this video but from my research i havent been able to find anyone else with this issue, maybe I'm googling the wrong things tho lol. Thanks for any help you can give!

      The chatter you hear is the stepper motor stalling due to an obstruction. Stepper motors work by moving in small steps, then another step and so on. When the stall, they cannot advance further, so it makes a loud bang. It's possible to destroy the motor driver if left in this condition and/or damage the stepper. So if it happens, then shut off the power and investigate.
      Now the issue you are describing is likely that the limit switches are not connected. Very rarely, the switch itself will fail, but it's far more likely that it's a connection issue The board tells the motor to keep going until it reaches the limits. The switches opens (or closes) and that tells the board where the limits are. So I would check your limit switches first and use an ohm meter to make sure when you manually press the switch, the signal goes all the way to the board. Always do this test with the power cord unplugged from the wall.

    You dodged a bullet there! Quick and easy fix. BTW, most limit switches are inexpensive and cheaply made. It's not uncommon for limit switches to fail. I toasted a huge NEMA 34 12NM stepper because of a limit switch issue and I didn't catch it fast enough. From now on I only use configurations with normally closed (NC) limit switches. Creality is using normally open (NO) switches.

      Interesting. I like the idea of the normally closed switches. I was lucky for sure. I heard a banging noise and knew I only had a few seconds to shut off the power. Fortunately the board and motor is ok but what a close call.

    I’m so sad bc this just happened to my Ender3 and nothing is unplugged. I am so new to 3D printers I don’t know what to do and I’m under a deadline to get things printed too 😭😭 if you can help me please reply! X

      First check to see if your limit switches are connected. you might also need to check to see if they are plugged in correctly at the board. One loose switch connection can cause this issue
