P2S causes power outage

Bambu Lab P Series Bambu Lab P2S
1

I was just printing some TPU parts when all of a sudden mid print the P2S restarted. While doing so, every other electrical device, connected to the same power breaker went dark for the fraction of a second and came back on. Same with the printer itself.
The powerbreaker does not trip.
This repeated itself 3 more times.
To be clear: 230V, combined power of devices on that breaker line ~ 1300Watts with the printer mid print. (Germany, rated to ~3600Watts per breakerline, depending)

After restart, the printer gave me:
HMS 0300-4100-0001-0001 095609
“The seytem voltage is unstable. Triggering the power failure protection function.”

Don’t get me wrong, im glad the printer has some failsafe features like that, but this adds up to all the many issues with this mashine…
Anyone else had something like this before?

Contacted support, lets see where this goes.

Looking forward to an update. If the problem keeps happening, I’d recommend having an over/under voltage protector installed in your electrical box (this is a job that requires a professional).

I’m worried that you have some other kind of problem in your electrics. You should check the outlet-to-outlet connections if they are a chain, and inside your panel the tightness of the main and neutral screws on the breaker and busbar.

Okay, problem solved. The issue came from a faulty wifi-socket.

The P2S draws considerably more power than the P1s, three times to be exact. It makes my lights flicker and causes my UPS to complain about over voltage.

Keep an eye on it and see if it causes any other issues.

Please add Low Power Mode to the firmware asap.
