I am getting an error manifested when I try to print this file. I have printed this file hundreds of times no issues. I tries reexporting the file and I also tried netfabb to "fix" it but nothing seems to work.

Its a simple vase mode print but its glitches on 4 layers and I can't figure out why. image and factory file attached.

your factory file slices perfectly on 4.01

so its likely the slicer doing it? I tried reexporting it no change. and I ran it through netfab. no change.

Try the repaired stl attached.

There was a geometric error!!

No joy this is the fixed stl sliced.

This may sound silly......but try duplicating and slicing the part twice at the same time

The artifacts go away completely. normal print. but alas I can't do that and retain vase mode (these parts are specifically designed for vase mode printing) and if I sequential print the artifacts come back.

NOW this is odd. when I sliced 9 the artifact was in all 9 but when I slice "JUST TWO" the artifacts are only in one. this makes it pretty clear this is a slicer bug. its literally a copy past of the same file !!!

if I then DELETE that rear artifacted file and only slice the "good" file. its broken again.

SO I went back to two files sequential printing a process for EACH copy. copy 1 has artifacts and copy 2 again has NO artifacts perfect print

if I then reslice but only select process 2 that had no artifacts. it now has artifacts. This seems to be clearly a slicer bug. problem is it was working FINE yesterday. I did not change the files and reexporting the file does not fix it and netfabb finds no issues.

ALSO if I reverse the processes print 2 first then 1 it flips. now the front one has artifacts and the rear one does not.
