Problems during installation
Hello everyone, I'm having a problem reinstalling my V.Core 3.1 400. I flashed a new card with the latest ratos version, then the start screen came up but then it stopped! Klipper doesn't connect, I can't flash my Octopus pro 446 board via dfu using the ratos Configurator and even when I want to flash the toolboard ebb 42 1.1 it is recognized but Klipper is disconnected and I get an error message again, it's been like this for days now. I can't even get to the Mainsail interface and everything is displayed as invalid on the Update Manager. I've swapped all the cables and specially got new cards to flash. I'm slowly at a loss as to what to do next, the printer was working perfectly before the Toolhead Upgrade 3.1 🤷😭😭 Can someone please give me a tip?

Is your raspberry PI connected to the internet?
Yes I have connected it with Lankabel at the beginning there is also a connection with Klipper but it disconnected
All those things are indications of no internet connection
It's possible it's a timesync issue though.
Power up the pi and try the following:
That'll show you what it thinks the time is
And whether it's synced with a time server
Wie muss How do I do that? Unfortunately I don't know anything about it. Can someone explain it to me step by step?
you're doing it right, just write "yes" to that question on the screen
then type
raspberry when asked for password
and then type in timedatectl status when it connectsThank you very much Mikl, I will try that tomorrow and see what happens 🙂👍👍👍
Hello Mikl Schmidt, I did it as you told me and confirmed it with yes but now I can no longer enter a password via my PC keyboard 🤷♂️😭
I somehow managed it, how do I change the time zone and the time now?
Hello. I re-flashed the board and set the time zone with sudo raspi-config to Berlin via ssh, then clicked done and exited the menu. Now I've restarted the Pi and it's showing me 12:30pm instead of 5:30pm. Why doesn't the time change?
I'm sorry i didn't see you posted, (i don't get notifications unless you tag me or reply to one of my messages). So indeed the problem is most likely time synchronization, this further indicates that the pi doesn't have a connection to the internet.
If you do:
and it complains, then the pi has no internet connection. Without an internet connection the pi won't be able to keep time, as it has no real time clock.
Each time it's powered off, time will stand still
The further you drift out of sync, the more likely that secure connections to the outside world will fail (this is a basic function of SSL - certificates can't be validated if you don't know the time).
A connection is needed to update packages, and for moonraker to determine the status of your system.
It's also needed to get klipper to compile it's dependencies (this is why you're getting the "Detected but unresponsive" error)
No problem Mikl, my baby is purring again. It was the WiFi connection on the Raspberry Pi. I also managed to get the time zone right and changed it to Berlin, but somehow it isn't saved on the Pi, but that's not a problem. The main thing is that the printer is working again. Thanks for your help anyway 😁👍
I just have one small question. The printer now does the Pam across the entire print bed. How can I change it so that it only does it on the area where I am printing?
Awesome! Glad you got it fixed 🙂
There's a guide in the docs on how to enable adaptive meshing, give me a sec and i'll find the link 🙂
Adaptive Meshing (BETA) | RatOS
RatOS comes with it's own adaptive meshing (functionality was previously handled by PAM by Helge Keck), similar to KAMP. When enabled and configured in your slicer, RatOS will only probe the print area and your configured probe location, potentially saving a lot of time on smaller prints on bigger printers. RatOS will keep the resolution of your...
Oh cool thank you 👍🙂
