Core one crash After longer print. BSOD (not a ground issue)
Hi. The last day I experienced my first blue screen. I printed two jobs wich took about 5 and 7 hours each.
each time the print finished but than the printer beeped constantly and showed a blue screen with some „marlin error“
I have my motors grounded, so that should not be the reason.
I printed a testpiece in 1 hour and it did fine. I than only altered one setting. I reduced the perimeter speed to the point where the print would take 8 hours. And after that I had the blue again.
Also varied the hight. But the longer prints course the error. Regardless of the height
latest slicer version. And happened with latest alpha an RC fw.
(Right now I’m printing 4 , 8 and 9 hour prints to see were it fails.)
any ideas ?
thanks

Hi,
just a thought: When you see the error again, maybe take a screenshot. The more information you provide...

it showed this.

OK... I see the line in the source code but this really needs to be commented by someone who is familiar with the firmware.
Looks like the printer has detected a condition where it's supposed to wait for a response that is impossible in its current state so it BSODs.
Taking a guess (knowing very little about the internals), this could be hardware misbehaving.
Is there any chance that electronics are getting too hot in long-running jobs? I'd take covers off e.g. the BuddyBox, put a ventilator nearby for some forced airflow and try again (not as a solution but to rule out localized overheating).
RE:
BTW are you running the latest firmware? The screen reads 6.4.0-alpha+11774 but I'd expect "RC" for the latest "release candidate" version.
Just double-checking (you wrote >>And happened with latest alpha an RC fw.)
A stable released version might be a safer bet...
