Has anyone run into an issue where the brim is missing? I have set it to a 30 mm brim. I tried auto, outside and outside and inside but it won’t generate.

Thank you. I appreciate the help!

Thank you. I though I was going crazy. :pray:

Don’t get a brim and the BRIM option is not showing up on the LINE TYPE list. (Win11 and BS 2.0.3.54) :v: :cowboy_hat_face: [Screenshot 2025-04-27 104011]

I think I see a raft? That takes precedence over a brim. With this model, between the raft and all the other joined support bases, I don’t see a need for a brim.

Nope. Raft Layers is set to zero and it does need a brim. These models are rings that have almost no contact with the build plate. Right now even with the tree supports when printed with 0.08 layer height they tend to get knocked off the plate by the print head and create a stringy mess. I’ve tried …

It get’s interesting. If the support threshold angle is 14 it gets a brim. If the support threshold angle is 15 then no brim. [Screenshot 2025-04-28 010044] [Screenshot 2025-04-28 005953]

I had the same issue, and was quite frustrated as I decided to comb through everything, and in the process → objects tab, then click on each part separately both had locked brim types as painted or no brim, which was causing my problems, I clicked on the lock and removed it so that the global settin…

i have the same issue, but none of the same solutions. changing support angle isn’t putting the brims back on, and the objects are not locked to have no brim

If supports completely encircle your object all the way up to the edge, it might not get a brim as the solver cannot find a place to put it. If you want your support structures to have a wider “brim” that is the setting named: “Support First Layer Expansion”

This was my issue also, Thank you so much, I thought I was going crazy.
