Thank you very much.

I have played with it and yes... I figured it was a "raft".

In regards to link I only see guides. There is no software.
Only software I can find from the link you gave me are the following:

FlashDLPrint
Flashprint
3Dtada
Happy 3D

Which one is the better one?

Thank you so much.

btw. Printing is so cool. I am restoring an Old lathe (seriously thing is built before WWI) so I am using this printer to replace the bushings.
Can't believe I waited this long to get a printer.
