How to attach support to model?

[Curadot 0]

Hi guys,

 

I use Cura 5.3.0, Printer: Ender 3 max, and have this model (bottom view):

Which contain two domes (actually a flat surface on top of holes) that need support, when using "Support touching buildplate", as soon the first layer of the support is printed it's pill off from the build plate.

Normally I print with all default settings for PLA and never had issue. I tested to increase temperature from 200 to 205 degree, it's worse.

 

 

I tried Build plat adhesion > Raft: it's print incredibly well but I end up to throw the part away because no way to remove the raft.

Now I'm just looking a way attach the base support to the model like illustrated on the left hole in the picture, but look like support do not want to touch the model even if I add more support around.

I do not want to do more experimentation and wast more plastic I already did.

 

Any Ideas?

I found it! I have to use brim and uncheck "Brim only on Outside".

Thanks to this guy! :

 

Now I just have to test it.
