Adruino self power broke down on 1.5.4 electronics

Recommended Posts

Posted · Adruino self power broke down on 1.5.4 electronics

Hi!

I have a Ultimaker with 1.5.4 electronics patched to self power the Adruino, it was working fine for several month but today the printer "died" in the middle of long job, as it came out the self power stopped working. Printer seems to be working fine if I power the Adruino via USB.

EDIT: As it came out, the 12v fan output leads on main PCB are indeed dead, no voltage on them, am I correct to assume that the most obvious source for the error would be voltage regulator on IC1 slot (L7812CV)?

Thanks!

Kirill

Hey!

Have you fixed this problem already? Seems that i have the same problem. My assumption is also the voltage regulator at IC1.

Thanks for your reply!
