Duet 2 Wifi Incorrect VIN Reading
-
My printer paused a few hour after I started a 20 hour printing job and show the message--
Error: attemp to move the motor when VIN is not in range.
Warning: VIN over voltage event (29.5V).I have checked the power supply voltage by multimeter, it's 11.95V, the fuse is also good at 0 ohm. Then I replaced other 12V power supply but the reading on the web dashbroad still show the VIN sensor is about 32V not 12V and I can't home the axises.
As my duet should be out of warranty, please advise on which part of the circuit may be related to this problem, maybe I would try to fix it by myself.
Also I'm sure that the power supply is good, is there any way to ignore the voltage checking in configuration and let me continue the unfinished print on my printer?

***Update:
I tried to use another power supply with output about 11.7V, the dashboard show VIN is 25V, but I can home the X & Y axis without error. I want to know is it safe if I continue the printing in current situration. -

@t9000 THIS thread had a problem with the Vin reading and it turned out to be a damaged resistor on the board.
Do you have the capability to check these resistors?
Will check it later today, thanks a lot.

just checked R80 is 18.7k ohm instead of 47K, and R81 is good, I will try to replace it asap.
-
@t9000 Well, THAT'S going to make your voltage read high!
You're the second person to have R80 either fail or be the incorrect value lately.

R80
Many thanks for your advice.
But I still have no ideas on how to replace it, the location of the R80 seems not easy to apply heatgun , maybe I should try to use the soldering iron first.

The VIN reading returned normal after replacing the R80. Thanks.

Was this a genuine Duet, or a clone?
