Cura unnecessary base and 2 different supports?


Recommended Posts

Posted (edited) · Cura unnecessary base and 2 different supports?

Please Please need some help. I am trying to slice my model and for some reason im having a few issues

1. Cura is adding a bottom "plate" where one doesn't seem necessary

2. There is a support grid, then what seems like a full "plate" in the middle of my model where there is not one in CAD. This plate and grid doesn't look like one intended to be "easy to remove"

3. Then the support the rest of the way seems like what I expect, easy to remove after the model is printed.

 

I have attached a few pictures as well as my STL. Note the layer numbers so you can orient yourself

 

What I would like to know

1. Why is there that bottom plate. I turned off all the settings I could find for bottom layers, set to zero, all of that! In the CAD Bottom picture, its clearly its not necessary.

2. Why is there a middle phantom full plate in the middle

3. The "Upper Good Support" is exactly what I expect to see, all the way top to bottom in the model, because it looks easy to remove after its printed... but again there is this middle plate and weird support under that.

 

I think I have played with every setting I could find. Searched the net, everything!

 

Thanks so much for the help!!!!

    I can see you used sketchup.  So all the white walls (for example most surfaces in the bottom picture) are good.  All the gray walls are bad.  Right click on all of those and choose "reverse faces".

     

    This color (white versus gray) tells the STL file which part of the model is *inside* (solid) and which is outside (air).

     

    Note that most of the surfaces in the upper sketchup picture need reversing.

    You are AMAZING!!! I have been using Sketchup for years but only recently got a 3D Printer, I never knew about the white/gray walls!!!!!

     

    Thank you SOOOO much for sharing!! Slicing looks perfect now!
