Faulty Smart Effector

tcj

Hi,
since today my smart effector seems to be faulty.
It continuously triggers even with the board alone (without heatsink, arms, fans ..), green trigger light and 1000 value in web control.
It flashes three times when turned on and then lights green all the time.
I can't see any damage

HELP

Thanks
Thomas

Thanks, but that is not the only thing that I tried several times but without any success.

post high resolution pictures of the front and back of the effector

I've already inspected the whole effector with a magnifying glass
There is nothing abnormally

When and where did you purchase it?

Sep '19 at filafarm.de
I've already sent them a mail

Phaedrux

Photos? Maybe we can see something you can't?
Wiring?
Did anything change recently with the printer?
When was it working last?

tcj

Wiring is ok - worked for months
Updated RRF a few days ago, but not yesterday
Working last night at last

Is that a scratch on the second photo on the bottom edge?

tcj

yes, but it's there since I received it and it is only on the lacquer coat

What M672 are you using?

tcj

tried M672 S131:131 without success - even no flashing of the LED
