There something wrong with the skirt line height cause i saw video on YouTube from "3D Printing Geek" about the 5.4 update and talks about brim removal and the new skirt feature which is skirt height. I tried this but when i did a preview the skirt height is only affect the closes innermost object and not the outside skirt.
I added a picture of the skirt height with added text in color.
My other problem is the brim easy removal. I'm not sure if its intended for a "heated glass surface or all surface" which are intended for small or large thin objects (meaning half inch thickness and longer/higher than 5 inches or more) but i tried to print on a non glass surface which is similar to PEI but the brim is still a pain in the *********************** to remove so i had use a sharp chisel to remove the excess brim. I dont remember if checked the smart brim option.
