Brims and Skirts

[UlrichKliegis]

Skirts and brims serve two very different purposes. While a skirt mainly provides a means to get a clean material stream from the nozzle and check for a correct bed leveling, a brim's mission is to hold the object down to the building plate, specially in cases of a small contact area of the object to the building plate.

Coming from Slic3r, I was and still am used to use a brim where warping may occur despite the use of borosilicate glass and a sophisticated heating scheme (PLA).

Today, I tried a brim made by S3D. Disappointment! Not only that I could not specify the width in millimeters like in slic3r but rather in loops, I had to learn that S3D uses the parameters for the building of the first layer to make the brim. As I use a fat overextrusion for the first layer to warrant the best possible adhesion (base paramaters 0.3mm nozzle, 0.2mm layer thickness, 300% extrusion for the first layer), S3D obviously used these values to make the brim, and instead of the loose loop spacing (just enough coherence to achieve a good holding pattern) employed by Slic3r, S3D packed the brim tracks in the same density that is used for the perimeter loops in the object - which led to a thick, fat wall, more like a rainworm, instead of the flat film of material generated by Slic3r.

I can't imagine that it should not be possible in S3D to achieve something similar. But how?

This is the second attempt to post this. This forum software seems to run the editor on the host rather than on my computer, leading to nerve killing delays between entering text and seeing the written version. When I had finished that after more than 30 minutes, I wanted to see the preview ... - Instead, I was asked to log in again (which I had done before entering the first text) - and then my whole elaborate was gone forever.

This is my last try - if it does not work, I'll publish my questions and constructive criticisms somewhere else.

Wrote this in my local editor and will copy and paste it into the forum text window.
That, at least, worked so far. But it is deterring users like me.

Thanks, cheers, and a happy new year!
