I am making a Prusa I3 and i have everything assembled and wired up. When i turn on the machine without a USB connection, the power supply (Thermaltake Purepower 2.0 350W) turns on for a split second and then shuts off. However, when the USB is plugged in and connected, it will power up. In both situations though, the motors seem to have no power (no audible noise, no holding torque). I have tried a different power supply and the same problem occurs. Not sure if it is the board not being set up properly or something to do with the power supply's safety mechanisms activating.
I am running windows 8 with Marlin firmware.
I got the board and motors from Makerfarm Ramps 1.4 Kit
All the wiring was done in accordance to the image on the Reprap wiki regarding the ramps 1.4 board.
