Sudden Print Failures

rphillips1991

I have been printing with great success for about a month now

Please see the below Ruined House - took about 3 days to complete, but as you can see was a great print. 



After this print i started a small 2 hour DND tile 'Archway' 

It failed around the peak of the arch, and so i tried again thinking just a blip. 
Second print failed at the same time, and so i thought it down to no support (the file is supposed to print without supports, but hey you never know)

i tried a few other shorter prints which worked, and so i loaded up a long runner which then also failed - this time at a different Z axis height. 

Spent today cleaning, changing nozzle, and re calibrating to try to get a successful run, but alas i am still struggling. 

The latest column print failing again, but still a different Z axis height,

The Cura settings are the same ones that have worked previously.

Any suggestions on where i am going wrong?

In what manner is it failing? Bed adhesion? If so, check your z-axis zero level (I had a print that kept lifting at the same corner so raised that corner a hair), slow things down and/or consider using blue tape.

Hi, Basic question:
Did You make Mesh Leveling again. I talk about that because after long long prints, it's necessary sometimes to redo leveling, because vibrations during printing. 
This is what I do often before an important print. 
The other thing to check : status of your nozzle who can partially be clogged , also the extruder motor mecanism, where you can have small parts of PLA  blocking the normal advancement of the filament. 

I suggest to check the complete filament line, clean your nozzle or replace with a spare one and make new trial with small print.
