Setting time manually without internet
All our IoT devices are firewalled from the internet so they don't leak or accidentally upgrade and lose features (I'm looking at you, Bambu). Network time can't be reached.
How do I set the time manually?
Vik :v)
RE:
You can't set the time on the MK4 manually. What works is setting up a WiFi hotspot on a mobile device, activating the WiFi on the MK4, connecting it to your hotspot for a few seconds until the time on the printer's display is set via NTP. Then you can turn off the WiFi on the MK4 and also the hotspot on your mobile device. You should change the password for the hotspot to a short one or no password for this to simplify the process on the MK4. Entering the password via the encoder wheel is an awkward process. Afterwards you can set the password back to a long and more secure one.

Right, will try. Might just fire up an NTP server behind the firewall.

Android has deprecated PublicNTP so I VPN'd a phone connection. Set it back to ethernet.
Why bother? One simple example of many: if a bad actor spots NTP time requests suddenly stopping from a device like a 3D printer, they know the user has likely turned it off to go on holiday...

I was able to change it directly on the printer. It is under settings. But you need to know what your GMT offset is.
RE: Setting time manually without internet
I do not agree with @pfa-2. You can not set the hours and minutes to the correct time from the printer display panel.
RE: Setting time manually without internet
Correct. It does not allow you to set the hours and minutes and it the setting is manual, as in it does not set directly from the Internet. But I was able to Google the GMT offset for my location, and input that into the control panel on the printer. It now displays the correct time for my area. Is this what you meant? Or am I missing something else?
I would prefer it just set automatically. This process did feel a little like setting the clock on an old VCR or the microwave oven, but it did the trick.
RE:
I think your printer must have been connected to the internet at some point, and it got the correct time then. I did that with my printer when I first got it. Since then I've disconnected it, and my time has been slowly drifting off. It's about 15 minutes off now, and unless I reconnect to the internet I can't fix it. It has nothing to do with the GMT offset. That will always change the time in one hour increments.
RE: Setting time manually without internet
Gotcha. Yeah mine is whole hour. No drift so far. We'll see.
