Discontinuous lines

[NMGMarques 0]

Hi all.

 

Having an issue with CURA. I am testing a print of a monitor standoff I designed. I designed it with 1,2mm wall thickness so I can print 3x,04mm walls and obtain the 1,2mm desired result. Trouble is, cura is printing the middle line in a discontinuous fashion, causing severe issues with adhesion, PLA buildup on the extruder hot end, considerably longer print times, etc... This happens in layers where it's just the wall being printed. If I check top layers, as soon as it starts working on those, it's all good.

 

This is layer 1 (of the test print as part is shifted down) and you can see the interrupted line in that bottom arc, though the top arc is ok.

 

 

All the way up to layer 13, last layer of just walls.

 

Then, starting at layer 13 till 16, when the top layers start, it prints the 3 walls just fine.

 

Attached, the 3mf file in case it helps.

 

Does anyone have any clue as to how I can solve this?

For future reference, I just figured out I could solve this by lowering the inner wall width to 0,3 though I have a 0,4mm nozzle and still, this makes no sense, why the top arc with the exact same wall thickness is ok, yet the bottom arc requires this change.

A) Generate a STL model with a smaller tolerance in your CAD software

Or

B) Use a line with for the inner walls smaller than 0.4 : Ie 0.35

Had to go all the way down to 0,3 to get it to work.
