Hi all, I've just finally got myself a reprap smart controller however when I try to power my arduino by a jack connected to the psu, the lcd screen doesn't turn on but it does if I plug the usb connection into my computer. Does anyone have any ideas?
Thanks
Ben
This usually happens when the voltage regulator on the arduino is broken. It usually gets burnt out when people try to plug/unplug stepper motors or endstops. You can repair it by replacing the regulator.
