Am I missing something simple here? I cannot get my GLCD controller or the rambo board to power on without being plugged in to my pc via usb. I have reset the board with the small button above the usb, is this supposed to tell the board to get power via the PSU and not usb? Is there a specific order i must follow in powering on / off the PSU, rambo switch, rambo button, glcd and pc?
I can print from the GLCD if I am plugged in via usb but of course this defeats the purpose.
