@AA5B It’s good for displaying information that you don’t expect instant updates on. Today’s calendar, tracking deliveries, news feeds perhaps. I haven’t really looked into any of the alternative use cases so I’m just using the cloud-based functionality.
I had one of the earlier original models and at one point a firmware update completely cooked it. I’m not thrilled about the e-waste, but the company handled it well and I got a replacement without any fuss.
@Trail A1 series? If you remove the nozzle there is a graphite (?) plate that has screws on the backside that can come loose and cause issues with bed probing. You need to remove the plate to get at them.
I’m sure Bambu has instructions for this but I don’t know what terminology they use.
But another possible cause is that the nozzle isn’t actually seated correctly. It is possible to install them so that the latch closes but the nozzle can still move around.
