Sanguinololu, Octoprint and dual 5V supply through USB

Post by onki » Mon Feb 04, 2019 7:26 pm

Hi,

I am using my Sanguinololu on a i3 Alu with Octoprint.
Since the USB connector to the RasPi will power the 5V when the printer is switched of I am a bit worried if this will not influence the lifetime of the 7805 linear regulator on the board.

How did you fix that problem?
Is there the same probvlem with the GT 2560 board since I would like to upgrade to this board because of switchable fan output etc.

Best regards
Onki
