I bougth an Ultimaker machine, I have assambled it, but when I conect it via USB, and installed Cura and Netfabb trial version. Neither of them worked.
Cura Installs but when I want tu upgrade the firmware to Marlin, It stays in "conecting to printer". I´ve tried to use it whitout upgrades, but when I import an STL file y doesn´t show me anything on the 3d screen.
While using netfabb, I´ve installed it, open clicked on Ultimaker on the rigth panel, imported the STL file, and followed the first step (
) but can´t configure USB control.
