Printing crashed with message: webServerTask. Precise data access error, precise bot. Any ideas?

 

Hi all! Any ideas what could that be?

Printing stopped about halfway, fans 100%, no resume possibility.

Thanks:)

I'd open a chat with support, it's some sort of software bug in 4.2.0 that needs fixing 🙂

The best is to produce the crash dump settings - save crash dump and attach it to the report, thanks

@zoltan

Can you still get back to the menu after a blue screen like that? I'm lucky enough not to have this issue on my printer, but had assumed it was like the Windows PC BSOD, and a reboot was the only fix.

Gordon,

unfortunatelly not. You have to reboot - developers are working on it.

@gordon-w

the crash dump contains stored data regarding this blue crash for further issue nalysis, so if you have succeded to get it, would be great if you could share it.

Same problem here - crash after approx. one second after selecting the "version info" menu (no LAN connection, no USB stick plugged in, no active print):

dump.bin: dump

@karl-herbert

Did it happened during long print?

Thanks for the dump. Will be transfered to appropriate programmer.

Should be resolved in 4.3 RC1

@zoltan

Thanks for the feedback! The printer was unused and idle for about 2 days. USB stick and network cable was not plugged in. No Raspberry and no Octoprint in use. I flashed the firmware, unplugged the USB stick and selected the "Version Info" menu. After about 1 second -> blue screen. The only version with which this does not happen is 4.0.2. I will test 4.0.2 and 4.3.0 RC1 again tomorrow and report (incl. dump.bin).

The problem is temporarily fixed with 4.3.0 RC1.

What does the board info "SZ?" mean ?

Thanks!

@karl-herbert

the line should contain the serial number of your board. It works for me correctly.

I suppose, you have original Prusa MINI without any bootloader flashing. 😉

@zoltan

Possibly it is because I removed the appendix and made some changes to the firmware. But it does not bother me, because I can work with it.

thanks for your efforts 👍

No problem at all. I have also broken appendix. Did you use for build the Průša recomended build procedures or do you  you have your own IDE environment?
