Minimizing Raft/Skirt dimensions manually on very large print objects

I’m new to 3D printing and want to print an object (I.e. large 3D glider) and the wing section is near the print area limits of this machine. How can I manually minimize or disable the skirt/raft from printing as that would exceed the print area on its own and cause print buildup and thus causing collisions with the extruder which rips up the skirt/raft in those areas. I tried setting those parameters for the skirt/raft to zero but they still come up in the printing. Is there something in the programming that overrides the settings somewhere? I use AutoDesk Fusion 360, MeshMixer with the BoXZY software.

Answer this question I have this problem too

Is this a good question?

Using Slic3r (because that's all I know) disable the skirt/brim/raft options, and go with that. I'd also heat the nozzle before starting the print and feed through some filament to get it flowing consistently as a replacement for the skirt.

What values do you use to disable these functions in slic3r? According to the information I saw, setting a value of 0 actually allows the program to generate its own skirt or raft. Where I am looking is in BoXZY Interface, Slicer Tab, Configuration Button, Skirt and Brim settings.


Configuration > Print Settings > Skirt and Brim

Skirt: 0 loops (bubble note: set this to zero to disable skirt completely)

Brim: 0mm (bubble note: default 0)

Configuration > Print Settings > Support material

Raft: 0 layers (bubble note: default 0)

I don't print with a raft, so mine is set to zero. I've printed without a skirt before, and 0 worked, and I don't use a brim so it's always been 0. Hope this helps, let me know if you need more clarification :)

Thanks! I tried those settings and the brim and skirt and both disappeared. Now I secure the projects with hot-melt glue instead to hold them down fast instead of wasting the filament and time printing those brims and skirts which don't work well at all.
