T6 Case Problem 1 Marlin Internet

[Ashlyn Robello]

Ihave instaled on my raspberry pi 3b+ octopi , that is conected to a mks gen l v1.0 motherboard for my 3d printer(ender 3 pro), soo wen i open my octoprint into a browser i can use octoprint . I wanted to install some pluggins ,but first time i had an error that said my server was offline , after conect my raspberry to wifi and set a static ip adress , i conect my raspberry to my main board , after that is said the status of octoprint was operational , soo i expected it will work ....

After that it said that my instalation doesn't have internet , soo i coldn't install pluggins . I see that in the "conectivity check" my host was 8.8.8.8 and my port 53, i press on test , there said "server is unreachable ".

Also on device manager pluggin write it is dezactivated, and a can't activate it

I now i tried it didn't work , also i tried to put the host 1.1.1.1 and port 27 but nothing , wen i an conected to the wifi on my raspberry , wen i search for ifconfig i see my ip at wlan0 , and wen i am conected trought the cable , on enx

are you sure there i at host , i have to put my ip , becouse thatwas a section taht said , it is loking for updates on that host , default , the google dns 8.8.8.8

" If the connectivity check is enabled, OctoPrint will regularly check if it's connected to the internet. This is useful to prevent resource intensive operations (such as checking for updates) if it's already clear that they won't succeed anyhow.

Define a check interval, a host and a port to check against. If you don't know what to set here, the default values (using Google's DNS server) should work. If you have concerns about using that, define the IP and port of a different online server that you trust and that has a high availability."

The Connectivity check should be left at 8.8.8.8 port 53. This is the address of one of Google's name servers and the port is the standard DNS port. If Test host & port button fails, then you do not have connectivity to the internet. You can't fix it from this page.

You mentioned that you set a static IP address. This is normally not necessary as the default is to use DHCP to obtain an IP address, netmask, gateway, and DNS servers. If you manually set a static IP address, you also need to manually supply the netmask, gateway IP address, and DNS server IP addresses. Failure to set these correctly would result in not being able to connect to the internet.

If one of your other systems is running Windows, open a command prompt and provide the output of the command: "ipconfig /all". If one of your other systems is running Linux, provide the output of the same commands as the OctoPi system.

If you want help, please post the output of the commands I asked for. If you changed files, post the current content of those files. Your interpretation of what you did doesn't help because it isn't working (not to mention the large number of typographical errors).

For the first case, this is either via port 80 (also known as HTTP) and would be using something like: as the URL. You might do this to check to see if both your workstation and the Raspberry are on the same network and can talk to each other.

For the second case, port 53 is related to the DNS client and is used to do DNS lookups. The related 8.8.8.8 IP address is that of Google's primary set of DNS servers so this makes sense. You might check this connectivity to see if your Raspberry Pi can talk to the Internet; this is a requirement for upgrading it in place.

@alex This sounds like it may be a problem with your network. You indicate that you added an Ethernet cable to your Raspberry Pi and plugged the other end into your Internet router. The connectivity check should have passed.

A standard installation of the OctoPi image onto a Raspberry Pi 3B, combined with plugging it in via Ethernet cable (and doing nothing else to adjust anything) should result in a Raspberry which can talk to the Internet. It's possible your other attempts to fix this are getting in the way. I would recommend starting over from scratch. You might find this useful as a troubleshooter as well as this for step-by-step instructions.

I had reinstal octoprint , now it is working , also the plugin and enthernet is working , but wen i want to move or to print , my 3d printer dont do nothing , in octoprint i had an error that printer healted , also wen i try on my tft28 touchscreen , it dont do nothing , juat now i conect all my wires in my mainboard , mks gen l v1.0, is the firmware, problem ? I instaled the ender 3 cobfiguration in marlin , from github , and modify that from standard , to setting for mks board

What is the problem?

This is a blog that has been a long time coming. From time to time, we get a request about how to configure networking in Failover Clusters. One of the questions we get is how should the heartbeat network be configured and that is what the focus is on this blog. I am here to say, there is no such thing, and never was, a heartbeat network.

In the picture above, we would want to select Private for our Cluster Communication to as to not use the Public which has all WAN traffic. All Cluster Communication between nodes (joins, registry updates/changes, etc) would go only over this network if it is up. As the picture shows, the networks are called Public and Private. As years went by, some started calling the Private network a Heartbeat network.

So let's say I have Private set as my priority network for Cluster Communications. If it is up, we are sending our communication through it. But what happens if that network wasn't reliable. If a node tries to join and packets are dropping, then the join could fail. If this is the case, you either determine where the problem is and fix it, or go back into the Cluster properties and set the Public as priority.

Starting in Windows 2008 Failover Clusters, the concept of Public and Private networks went out the window. We will now send Cluster Communication over any of our networks. One of the reasons for this was reliability. With that change, we also gave the heartbeats an additional purpose.

What the heartbeats are going to tell the Cluster is to use one of the faster networks for its communication. With that as the case, it is going to use either Red or Green network. If the heartbeats start detecting that neither of these is as reliable (i.e. dropping a packet, network congested, etc), it will automatically switch and use the Blue network. That's it, nothing for you to configure extra.

However, because of all of the hype about klipper recentally, and the Sidewinder x2, it might make more sense for you to keep klipper on that printer, and help the people get it set up to their network, ecterra, ecterra. Reason being, you might be able to get a bit more out of it. But its your choice. Here is a video about marlin setup in case you would like to create you own configuration. Ender 3 V2 - Marlin Firmware Upgrade - 2022 - Chris's Basement - YouTube

Then I read somewhere to download the latest vcp drivers from VCP Drivers - FTDI

The latest executable for windows installed nicely and when I plugged in the usb, the printer was recognized as a usb-dfu-device.

I used stm32 cube (from artillery website) to flash the stock binary without having to run pronterface. It worked like a charm.

This issue just recently popped up, I believe it was after the last Firmware Upgrade. I have kept my firmware up to date, I had firmware 1.05.01.00, and upgraded to 1.05.02.00 (i believe the was the number it is the current newest)

Hello,

Thank you for contacting Bambu Lab support. I am sorry to see that you are experiencing problems with your printer, but rest assured we will provide support to solve them as soon as possible. In this case, the problem seems to be related to the LED light.

This behavior is normal as it generally turns on automactically when the pritn starts, The only time it may turn off by itself is if the printer has been idle and goes into sleep mode, However even then it still may remain on.

one of the reasons I can confirm this is because if you print from either the bambu handy, or the bambu studio app, the light turns on even inside LED turns on even before the print is done downloading.

If you want to stay up-to-date then you should grab the newest version of marlin (e.g. here, idk if 2.0.x or 2.0.x-bugfix is the one for you) and re-insert your configuration headher files and select the correct environment in the default_envs = xxxx expreession of the platformio.ini.

Hi Max,

this sounds like a good way! I definitely need some time to check and rebuild the whole thing.

But man, I will definitely include you in my evenig-prayer for your kind help!

Would you mind if I come back to you in case of further problems?

Best regards

1. I've added a Ziflex on the plate, but unfortunately I can't use my printer anymore because the calibration is only physical (using screws) and I've reach the end before teh right settings. On the Ultimaker 2 Go there is a 'software' calibration first where you can move the plate up and done, which would solve this issues. How can I do the same ?

2. It's very slow to start, much much more than my old UM2GO, way more than my laptop... And it's brand new, what's happening ?

3. The feature "Skip cooldown" introduces some bugs : If I change the material, then skip cooldown, and immediately start a print, it will hang forever on the "preparing" screen.

4. How can I change settings while printing, like the printing speed ?

5. I'd like to use my printer on my local network, without internet, how can I do that ?

6. The open WiFi of the printer is always on, even after it's connected to my network, how can I disabled it ?

I'm on firmware 1.2
