Printer

Bambu Lab A1

How to reproduce

Set up any print with support structure
Adjust the brim-object gap setting under Others > Brim > Brim-object gap

Actual results

The gap between the first layer of the support material is governed by brim-object gap, as if it's meant to be a brim that connects directly to the main print

Expected results

Brims should connect to the print according to the brim-object gap setting, but it should be possible to configure support structure to maintain a small distance from the print while also having connected brim material.

I usually want brim material to connect and adhere the print to the printing surface, but I never want the support structure to fuse to the print except for the specifically required interface point.
