If I put in the Separation From Part section an value other than zero then I get a separation from part.
In other words if I put in 10 in the Upper Vertical Separation Layers I will indeed get 10 layers of no support below the part that I want to support.
This does indeed make cleanup very easy as there is 10 layers between the part.
But the part above is printed in thin air and is not so easy to "clean up"
Just what is this setting for exactly ? It's kind of counter intuitive.
Supporting circular structures via the automatic support generation is not too flash either.
I have a 25mm circle with a ledge going around the inside.
If I generate auto supports it just puts 4 block structures at 0 45 180 and 270 degrees to support the ledge and the rest of the circle is unsupported.
What ?
