Hello,
I am about to finish my I3-R 3D Printer. What confuses me is that the Ramps/Arduino is still on when i switch the Powersupply off. As long as the computer is on the Arduino is on.
Is it that it gets the power from the PSU and the USB in paralell?

regards
Ernst

Hi Ernst !
Yes it's normal, as long as the ramp is powered by the USB, it stays on !
The only solution is to unplug the USB port !
