i received the solidoodle 3 today.
First installed software package “use the Repetier package above” from solidoodle website.
Started software and switched to red/green
Unpacking printer and plugged into power, plugged USB in and connected to PC.
Clicking connect in Repetier Host software.
Displays OK and red and green switches in software are on.
But printer does not move or heat, when clicking at manual control, neither at x- y- or z moving, nor on heating extruder.
Temperature displays always 0,0°C.

Then I installed
“Note: In some cases the drivers will not install on their own. In this case the drivers should be installed from here.”
Driver software, but does not solve anything.
