Link lost #35331 (CORE One L)  

RE:

Reported issue to Prusa CS last night, useless as usual. "WE are investigating this issue. Unfortunately, With complex printers, the issues can be complex too "

Downgraded to 6.5.2, Hard Rest to 6.5.2. Printer was off last night. Started cold printer this morning, successfully printed the 8 hr print. Doing another shorter print and then will do again the same 8hr print. I really hope this is a firmware issue for 6.5.3 and not a hardware issue.

I've had these Link lost faults also on 6.5.2...

RE: Link lost #35331 (CORE One L)

Thanks, I completed 20hrs of prints without issue. So if you saw this issue on the 6.5.2. Then it appears to be an issue with the firmware in general, we can assume then, the hard reset did clear the issue for now.

RE: Link lost #35331 (CORE One L)

So did the older FW fix your issue? I still dont have my replacement Core One L. This is taking forever and I am really considering if this was a good choice. 

RE:

I went back to 6.5.3, not much of choice if I want the MMU3 to work, as that was the first compatible firmware.  I have not seen the issue repeat, just finished a 24hr print.  The hard rest which reformats and then reinstalls the firmware "solved" the issue.
