So had the A1 for week now and there other day we noticed the house lights flickering occasionally. Turns out it's the A1's heatbed that causes it. There's lots of reports from other users with the same issue online.

Does anyone here have the same problem or managed to find a solution?
 
This doesn't help you, but no issues with both our A1 & A1 mini running at the same time.

Have you tried a different power outlet on another wall?
 
Yeah, originally had it running downstairs. Now upstairs and with same issue. Notice it on main light in living and kitchen etc but also lamps plugged into wall sockets.

Seems to affect quite a lot of users.

AC Power - bulbs flickering when A1 in operation

I’ve noticed that majority of my LED bulbs are flickering when A1 is printing. It is barely noticeable, but once you see it you keep concentrating on it. House is ~15 years old, no issues with electricity. I found multiple users with similar issues on reddit, one of them mentioning: The AC...

That’s not right, I have an A1 and P1S both running at the same time on the same 13A socket and smart bulbs throughout the house and haven’t experienced this :-/ What happens if you boil a kettle from the same socket the printers plugged in?

Does not sound right at all.

Is your house earthed, how old is the consumer unit and has it been checked in recent years?

If it were me I would be getting my electrics looked at by a professional. If the above is all good then I would be looking at sending it back!
 
My A1 printer, my PC (with a 9800X3D/RTX4090), 3 monitors, home server (x670e system) all running from the same 13A socket and no issues here.

Even when I'm gaming, and printing at the same time it is fine.
 
Last few days printing

This is worrying. it sound like the printer is drawing more current than the circuit its on can provide, without tripping a breaker. This is beyond the internets pay grade and i thoroughly recommend you get an electrician to check your circuitry in case of any potential issues with your wiring. This is potentially very serious.

When I say flicker it's only noticeable if you concentrate on it, barely notice it and probably wouldn't have unless my wife mentioned it. She seems to be more sensitive to it. Also it's not all lights, just certain ones.
I've boiled a kettle plugged into the same socket as the printer but that doesn't cause any flicker. I don't have a way to measure the power dray at the socket but the kettle has to be drawing more power than the printer. Only the printer cause the flicker.
I'll fire Bambu Lab support and email about it and see what they say. If you look at the thread I posted in my first post quite a few people are affected.
