Printer can’t be initialized

My MKII extended printer can’t be initialized. Connecting it to the pc works perfectly, though. After that it says “not initialized”, but pressing on the initialize button does nothing. I also tried to initialize it by press and holding down the button at the printer itself. It just beeps once and that’s it.

I’m now waiting for a whole week without a response from the Cetus support. I sent them a video that shows the problem, but the issue is still open. It’s really frustrating to have a 400 Dollar printer that does nothing. I’m really disappointed about the support quality and response time.
