Creality Official K2 Plus Print Head Cable, Original Hotend Mainboard Connector Wire, 1250mm FPC Flat Flexible Cable Replacement for Extruder, Nozzle Adapter Cable for Creality K2 Plus 3D Printer

but still looking for the issue and for it to not work long-term most of the time I can turn it off turn it back on and it works. Im guessing you come back to it basically off/paused with the CFS blinking red? Maybe a 2796 error? Maybe sometimes it just pauses the print and you keep having to resume it? If that sounds familiar its your print head cable. Linked below. 10 minutes to replace and and I have had no issues in months. https://a.co/d/06d5CuUB
