I'm printing with an Ender 3 and when printing, after about 40 minutes, it starts to make a thudding noise and layer shifts. I'm suspecting that the thudding noise is from the friction between the nozzle and the print or it's the printer X and Y axis moving really quickly, but I'm not sure. I'm a bit new to 3D printing, but I've printed things way bigger than this and it works. I also kinda want to avoid modding or changing any parts on the mother board.
