Bug Weird misalignment for certain ”bridge” layers

[reza-v 0]

When i try to enable bridge settings in the experimental section, these weird misaligned layers appear at the same layer height as the bridges. This happens with any number of perimeters or percentage of infill. For each bridge, there is only one misaligned layer only at the same layer as the bridge. It didn't seem to happen with every model i tried but it seems to be mostly on thinner models. I tried reducing the line width, number of perimeters, fiddling with every bridge setting, same thing.

 

My relevant settings are:

Layer height:,0.3

0.5 mm nozzle and line width

Custom printer, 350x350mm

3 perimeters

3 top and bottom layers

20% infill

Latest version cura 5.4

I was going for strength and dimensional accuracy.

I Also have tried viewing the Gcode with another software and the same thing appears.

Cura 5.4 is known to have some slicing bugs. Try using 5.3.1 instead and see if that helps.

 

Also, in print settings under Walls, make sure that Wall Thickness is a multiple of your line width. You could also try messing around slightly (by that I mean either 1 and probably not more than 2) with Wall Distribution Count, which controls how many walls can be changed to deal with the thickness of the interior not always being the same thickness.

 

If you could provide a .3mf file of your project (File > Save Project in Cura) that might help get to the bottom of the problem.

Try lowering the "Maximum Resolution" setting (under Mesh Fixes) to 0.2 or even 0.1.
