Just got mine a week ago.  When you turn on LAN only mode a message pops up stating connectivity with Bambu Studio will be lost.  Not only can you not see the camera, you can't send print jobs either.

@Greg in LAN only mode Bambu Studio doesn't connect automatically, you need to go to the device tab and click > to expand the list and it should appear there with a MAC address that you can click on.

The printer was there, even listed the filaments in the AMS, but wouldn't let me print.  I don't recall the exact error message, but the message on the printer itself stating connectivity with bambu Studio would be lost lead me to believe it was intentional.  I fiddled with it for quite a while before giving in.

Strange, one thought I've had meanwhile is my PC is connected to the WiFi router over wired Ethernet. If you've got both connected over WiFi some access points have client isolation so two wireless devices can't communicate with each other. Maybe the discovery / AMS uses broadcast packets that get through but the file transfer / video feed gets blocked.

<p>For the current range of Bambu Printers (P1P\X1-Carbon). If you store your files in the cloud and initiate a print through the phone app to the printer using wifi, what happens to the print if the printer loses wifi connectivity for an extended period of time during the printing process and is unable to recover it?</p>
<p>For example, if you are 1 hour into a 5 hour print will it continue to print as normal until the print is complete using a cached copy of the file that it downloaded during that first hour, but without app connectivity.</p>
<p>Or will it simply stop and wait for the user to perform a corrective action.</p>

While I don't know the answer to your question, the scenario that you pose would be a strong argument **against** using the cloud to print from.

If the printer simply downloads the entire file before it starts, and then prints it from it's local memory card, the only downside would be the loss of remote monitoring.

My Creality Cloud box required an SD card to print wirelessly. The box simply downloaded the file to its local memory and then printed it from there. If it lost wireless connectivity during a print it wouldn't even be aware of it and would just continue to print as normal.
