the object i was printing was an Apple Watch charging dock. The Chac Mool one from MyMiniFactory. I've tried printing it 4 separate times. each time the print just stops. Initially i thought it was getting stuck. But having just witnessed the stopping. i now know that is not the case. the printer freezes. it claims the hotend and bed are still at printing temp though they are cooling and soon cool to touch. i have tried shutting down and resuming print but the carriage locates incorrectly and lowers too far crashing into the print and dislodges it from the bed. seems to happen after the 3-4 hours of printing mark. anyone have any ideas. this is really becoming frustrating. i'm going to try another long print. i seem to remember it happening on another but not positive so i will try it to be sure its not the file.
