Brim inside an object problem.

[jkuk 0]

I'm trying to print a box with some letters on the bottom in PCABS. Only way I can get it to stick is weith a brim. The problem is, cura is putting the brim inside 2 of the 3 letters which is making them not look like letters anymore..
The "Brim on outside only" is ticked and with it unticked, all the letters get filled in.
Any ideas how I can fix this?
I sliced the same STL file in Ideamaker and it didn't have the same problem, but I really like Cura and have gotten used to it now...

I'd just turn off brim.  Maybe show a photo of your part?  It might not need brim.  Especially if the outside corners of the part are rounded.

 

Another trick is to use skirt but set the skirt distance to zero.  This will DEFINITELY give you brim only on the outside and will skip areas of the part that don't need it.  For example if you are printing a starfish the brim will touch the 5 tips but as a pentagram so only touching the tips which is the only area that needs it.

 

3rdly you can do your own brim in CAD.  Just put round disks at the outside corners of your part and make them only one layer high (0.3mm).

Skirt at 0mm will work.
Thanks.

I don't know whats changed. It was fine. Too much button pushing on my part. Seeing what stuff does 😁

Sadly that only works for single objects. I'm trying to print multiples.

Please show a screenshot of your part.  Are you certain it needs brim at all?  Most parts smaller than 60mm in X or Y don't need brim.  I'm curious how sharp the corners are and how far apart and how much material in between pulling as it shrinks.
