Just had my first crash of the Duet Wifi at the end of a 23hr print. Looks like it was at the last few layers. I have my board now I think 3 years or so and used it regularly.
It happend when I tried to connect to the DWC and it paused and rebooted.
It's strange - what could have caused that?
Is there a way to continue the print where it left off?
Many thanks.
