I’ve been having an issue lately with this one particular piece where randomly it will generate this line across the whole thing that isn’t really connected and causes it to break in half very easily, as if it missed an entire layer. In my picture you can see an example close to the top of the gap line just cutting across both the supports and the piece itself. Sometimes the line cuts across the middle half way up, sometimes it’s on the first quarter up. Any ideas what could be causing it? All I can tell so far is it’s not the STL because the line appears at random heights each time I print, so it shouldn’t be on the model itself. Also I’ve done a cold pull recently and got a new extrusion gear so I don’t think its the nozzle.
Same here, today one of my print broke on a layer. It look like one layer gone missing
