Printer offline from bambu lab and cannot bind from bambu handy

Bambu Lab P1 Series
22

Same problem to my P1S trying to understand what’s happening but cant see any troubles. I tried to open 3000, 8883 ports to bambu and it helped me for 1 print. And now it doesn’t even work anymore

Brand new P1S with AMS, worked fine for 4 days. Then 2 thing happened: I decided to turn off the light and I left it a hole day without pinting… and the problem appeared! It’s connected to the wi-fi correctly but the Handy nor the lab can’t connect.

And not, it’s not a network problem. I’m used to work with networks and have a ver good and realiable Asus router + external ONT.
It sounds like the machine goes to “deep” standby mode and can’t recover correctly, but yes, it’s awesome that YEARS after a client complained, it is not fixed yet O_o

Have you tried power cycling the printer yet?

After rebooting, it shows no IP (well, shows 0.0.0.0).
I set an static IP for the printer MAC on my router, not sure if it will helps because I saw no option for static IP, it seems that DHCP is mandatory.
I also relocated my WiFi mesh nodes to be closer to the printer.

As I see on this forum, the problem might be a conjuntion of

  • The printer anthena is very poor. That normal on IOT devices, so I don’t really complain… just makes much more frequent those “network” issues.
  • It uses a microcontroller, not a CPU. That’s a really bad choice as it limit the bandwich and other aspects on the network, but should not affect the stability or the range.
  • Even the hardware is encrypted, so you can’t modify any piece as the anthena (at least not easily). That’s a very bad point… I know that I didn’t bought a DIY machine, but this sounds like Bambu can prevent the machine for working if they wish…
