Hi,
Skirt/Brim does not seem to be affected by the first layer underspeed.
I have difficulty to make it stick. Should it not be printed with the same underspeed?

A simple test shows that the first layer settings DO affect the skirt/brim on the first layer. Just look at the gcode. For example, if I halve the first layer speed, the speed of the brim cuts in half. So it seems to work fine here.

I can see that it changes, but the speed is greater than for other areas. Logically, it should be lower. Compared to the raft's speed it´s 4 times as high. The reason for both is to ensure good adhesion to the building plate.
It seems like raft uses the % of outline underspeed while skirt uses the % of default printing speed.
When I print PLA or ABS it´s mostly no problem. Now I´ve been printing PET-T and it´s been more problematic . Would be great if skirt used the out underspeed as well, function would be improved.

I've seen this same issue, and agreed, it'd be nice if it used the underspeed vals of the raft. Or simply had it's own custom underspped val.

I can confirm this is still an issue. Version 3.1.0.
Why is this not fixed yet?

We need more control over Brim/Skirt
