Hello Raby,
thank you for your comment. I’m thinking for heated bed (for example MK3 or?) upgrade but i’m not sure should i use stronger (more amper) power supply for the vertex3d and the heated bed or extra laptop charger http://lbmakersociety.org/2012/12/creating-hacking-a-reprap-power-supply-for-ramps/ for the Heated bed? I wish to install second extruder for the second color option but i’m waiting because i must practice much more for one color and learn to use ABS filament printing.
I’ll steal your thread to post a picture of one of my first prints as well (after some cumbersome tweaking). But damn, I’m impressed by the quality of prints at this price!
