AC controller fault

Come on guys...... This is getting ridiculous. I have Several printers including PRUSA printers that are all on the SAME power circuit. The CoreOne L is the ONLY ONE that shuts down constantly.... And yes it does it when I move it to another circuit, in fact it does it when connected to a $1000.00 Dollar line conditioner that runs Lab equipment. This is NOT a power issue this is a CORE ONE L issue......

PLEASE FIX THIS. It's reminiscent of the one the MK4S had that you simply turned off the notice and shutdown for.

FIX IT...... PLEASE....

I've also had this issue with my core 1L this evening. Everything was working fine as I was printing PLA up until tonight. I've only owned the printer for about one or two months. Once I tried to print PETG, I got the error "AC controller fault." The bed is operating outside of specifications with error code 35338. I spent about 2 hours on the chat with the technical support person, and we tried a lot of things. We tried downgrading the firmware. That did not work. We tried upgrading the firmware back to 6.5.2, but that did not work. They asked to remove the back cover so that I could check the connections and ensure they were solid. Even unplugging it several times and plugging it back in did not help. A few times during the operation, I was able to get back into the main menu, but when we went back and tried to print with PLA, the red screen came up, and I got the same error. After spending about three hours on this this evening, I had to stop and go to bed because it was extremely exhausting.

I have owned the process MK 3S DMK four, as well as a core one. Each one of them is great, and I would sell the previous one to upgrade to the latest one. The core one L was working great until the situation, and now the printer is dead in the water. I hope Preuss technical support can help me get this thing back up and running as it was previously steady as a champ

My mains are working fine with a MK4s in the same circut printing happily through SEVERAL of these errors on the CoreOne.

THIS IS A COREONE ISSUE...... Please FIX IT

Two new C1L received yesterday, both stopped with the same error this morning. They are connected to the same outlets where I previously had C1 printers. One XL and two C1 were also printing this morning and none stop or had to resume so I'm ruling out a power failure. Got in touch with Prusa support and they instructed me to return both C1L under warranty.

So... is there a way to recover the print? And time out the blaring alarm beeping forever? The QR code leads to this fairly useless article.
