Hey I’ve been there. Take it apart carefully and inspect it as you go. Do lots of reading, clean it up, put it back together and hopefully it won’t happen again - but know that it might if you don’t find a cause. Sometimes things have to get worse before a cause becomes obvious.
I’ve got a Prusa, but I’ve had to replace many different parts on it, sometimes multiple times. Some of that was factory issues. Some of that was my fault. Some of it was just bad luck.
I still love the hobby, but it sure as Hell isn’t trouble free.
