Currently there is no speed option for brims when not using a raft.
The first layer speed can be changed but this does no effect the brims.
Slowing down the brim speed is needed for reliably printing brims when not using a raft, as without it the brims do not adhere to the base quick enough.
I’m having this exact problem too. The default speed for the brim is way too fast and without any option to change it the print turns into a mess as the brim does not adhere.
Worst thing is you can’t get rid of the brim as you need it to prime the nozzle, otherwise you end up missing some of your first layer.
This is a MUST HAVE FEATURE!
Is really impossible to print PLA based filaments using the Brim. The brim’s lines are printed too fast!
Please Zortrax team insert a speed setting for the Brim! We need it!
