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

Best places for bug reports like this is https://github.com/prusa3d/Prusa-Firmware-Buddy/issues

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

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.

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

Gordon,

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

@zoltan

Thanks, I thought that wold be the case but your comment about saving crash dumps made me wonder.

@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.

@jnousis

how long time took the halfway?

what USB stick are you using?

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

A firmware update has been posted with a fix for this problem https://github.com/prusa3d/Prusa-Firmware-Buddy/releases/tag/v4.2.1

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

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 

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

@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).

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

@zoltan

The problem is temporarily fixed with 4.3.0 RC1.

What does the board info "SZ?" mean ?

Thanks!

@karl-herbert

can you check please if it appeares also in the English? I will check other languages as soon as I will be at my printer

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

@zoltan

certainly, here is the result:

@karl-herbert

Thanks will do myself and forward for further investigation 

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

@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. 😉 

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

@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 👍 

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

@karl-herbert

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?
