Question regarding spacing between brim lines.

[mrdindon 0]

 

So basically my printed jobs look pretty ok since I changed my print profile based on what was recommanded at all3dp in order to make first layers look better:
https://all3dp.com/2/3d-printing-first-layer-problems-how-to-make-it-perfect/ 

But the thing is since I changed that, I was not able to adjust Cura anyhow in order to have the brim lines to touch each other anymore.
I tried tweeking the following settings without any success (see attached picture - it shows only the brim since I cancelled the job right after it)

 

Initial Layer Line Width : tried between 100 - 200%
Skirt/Brim Line Width : 0.8 - 1.5

Since my understanding of brim is that these lines should touch each other in order to give a better adhesion to the bed, does anyone knknow how I could fix that ?

Here is the complete settings for the last test I did with the following settings :
Initial Layer Line Width : tried between 200%
Skirt/Brim Line Width : 1.5

Looking at your settings, your nozzle seems to be a 0.4 nozzle going by the normal print line width settings you have. But i see you are going with a line width starting from 0.8 with the setting " Skirt/Brim Line Width:" what in the settings above you got last set at 1.5.

 

This means your asking the printer to make a single line thats 0.8-1.5mm wide when you only have a nozzle thats 0.4 wide. So set the " Skirt/Brim Line Width" setting to between 0.35 - 0.4

 

Also just to add, if you want a wider brim, you edit the "Brim Width" setting.

Found my answer... Had to adjust Skirt/Brim flow rate 🙂 all good now !
