Since upgrading to 1.7.2 the Ender V2 will just randomly stop printing and sit there melting the part where it has stopped. I have just turned serial logging on so have no error logs yet. The octoprint screen just seems to sit at the point it got to with no error messages I can see.
I think the lack of octoprint.log is my fault, I deleted it and serial.log to get fresh ones after I realised I might have a problem. It prints fine from the SD card. I did two prints last night from it. I have had zero problems with this printer and octoprint since I got it a couple of years back.
octoprint.log actually hints at a faq entry next to the error:
