Questions by Delta newbie

Hi All,

I am waiting for my new Rostock Delta mini pro kit and to replace my Orca (that crashed the main board recently) in mean time I have some questions.

1) Who sells the circular blue tape build surface ?

2) What should be Repetier home positioning coordinates ? Does it home in the middle ? Seems logical to me ?
However, the config by the supplier says that after the print, the head should move to x0, y0, z0

I think this will crash the head in the object isn't that so ?

3) Has anybody upgraded such a printer to obtain a heated bed ? If so, by which parts ?

Thanks Thomas
