You can find a lot of these defects in the layer view. When a component is to small or a wall thinner than your nozzle you won’t find it there.

Download a copy of Autodesk Netfabb. It is a great help in repairing defective meshes.
I suspect the model is up in the air, so before it prints, it prints the skirt.
You don’t see anything printed, probably because, you’ve disabled supports.
This is just a wild guess!
Thanks but I center it after every change and make sure there’s nothing lifted. Also my model has connected parts so i enable support.
It’s not brittle but thanks for suggestion. Everything is only a couple weeks old.
I tried that and it’s weird the layers all look great. Should layer view also show supports if they are enabled?
its the newest cura 2.x something.
I’ll check that but the machIne is only a couple weeks old so I hope I didn’t get a defective part. The filament moves if I manually extrude though.
In which case, it could definitely due to the model being not water tight(should show up clearly
in Cura’s layer display). Also, there are rare cases, some plugins, or previous setting cause
an issue with Cura, in which case, you could either switch to quick print and then make changes
by switching to the expert settings. But if none of this fixes the issue, that to rule out any model
related issue, just try printing some known good models. Also keep a watch on the fan(sometimes
having too much fan at lower temp, could easily clog nozzle, and grind the filament, making it not
extrude afterwards).
In case you didn’t see my mail, I’ve printed your model on an UM3 using Cura 2.4 and it worked out just fine. So, nothing wrong with the file. I also tried it without support to see how the printer would react. After the skirt, as expected, it simply produced a mess of PLA.
Thanks for the tip. Couple of other people printed the exact same file without any issues. I have been able to print some other models but my machine seems to randomly dislike some. Someone gave advice to checkfor heat creep so I’m going to do that too.
