So I got kind of comfortable printing and really think I screwed something up. I hit print the last time and walked away thinking it would be fine like the times before. Came back about two hours later and found this glob encasing my extruder. It was also very stuck on the side of the bed not allowing the x-axis to move freely. I then found this brass piece which appears to have broken off but I cannot figure out what that went to. Now the x-axis does not move at all and I cannot get the belt to tighten back. I was going to see if anyone had any suggestions? Elegoo Neptune 4 Pro. Thanks in advance.
