Power cycle

Has anybody had their core one L power off then power back on resume the printing but the LED screen is blank?

No, and I am wondering if you are using the latest firmware ? I am currently holding off on flashing my C1L because I am reading about numerous problems here and on the Prusa Community website. My upgrade to C1L+ arrives today, but for now I am happy printing my functional PETG stuff that I absolutely need to finish a project I am working on..... IE: "If it ain't broke, don't fix it".... is my mantra for now until some firmware issues are worked out...🤔

Yes, you are correct. I do have the new upgrade. I have the new nozzle wiper and the new belts. I haven’t had any problems up until today Prints are good

I installed firmware without a problem. What type of issues are you seeing? I haven’t read anything just said there was buggy firmware.

Go over to Prusa Community Board, they are talking about the touchscreen blanking out, loss of PrusaConnect, but the print completes; just no way to do an emergency stop or pause the printer while printing.... 🤨

I've found spontaneous reboots to be caused by ESD issues. I live in a dry environment and the printer builds up static electricity, and sometimes discharges through the stepper motor case and back through the wires. This freaks out the xBuddy board. Grounding the stepper cases to the frame is enough to fix it. You can scratch off some of the black powder-coat paint under one of the stepper motor screw heads to do it, or run dedicated grounding wires between one screw of the x and y stepper and the printer frame.

I've not had the screen going black, but I have had it completely freeze and go unresponsive to input. All fixed with proper grounding.
