We were able to print two things and set it up for a long build. Came back in the morning and found the PLA hanging loose. Pushed it back in. Started the job and left...no, I didn't wait to see if it was extruding...my fault. And of course, just an "air print" of the object....the head made the moves but no extrusion happened. So, following a video on the forum, I removed the two screws and can barely see the top of the PLA fragment in there. Can't reach it with tweezers. Not sure what to do next and am looking for suggestions on how best to remove the broken piece off. Thanks!
