I have a Flashforge Guider 2s and like many 3d printers these days, it has wifi and ethernet. It appears as if Octoprint only works with printers connected via USB. Is this correct? If I was to try and add support for network printing, could this be done via a plugin or would it need to be a core change to Octoprint? Thanks for any guidance on this.
If you have been working in the I.T. field within the Linux speciality for the last decade then you might consider rfc2217 as a solution. Search the forum here for a write-up but it won't be easy and it still involves a Raspberry Pi Zero W, for example, connected to your printer. It can connect "over wi-fi" though from the Raspberry Pi 3B somewhere else in your home.
I'm happy to have a go reverse engineering it. I've looked at the tcp data being send it it and it looks like standard gcode. I've made a simple python script that has sent/received data over tcp. I'm just wondering if I could make a plugin (maybe using virtual printer?) to benefit both me and octoprint.
I am trying to set up automatic updates via Ethernet using the LM Flash Programmer utility. The help within this utility states that if you listen on port 9 for the magic packets you can automatically kick yourself into bootloader mode and thus allow the LM Programmer tool to automatically update to your device, via ethernet.
The LM Flash Programmer says "Program Complete - 97512 Bytes Programmed" which I assume means everything went through correctly, BUT after it reboots itself it never brings up the ethernet. If I then manually hit the reset button on the launchpad, everything comes up as expected.
Vincinius, is calling SoftwareUpdateBegin(g_ui32SysClock) all that is needed to get the device to program over ethernet? Do you have to mess with bl_config.h or any of the bootloader code? I am wondering because I get stuck in the default interrupt handler after calling SoftwareUpdateBegin(g_ui32SysClock)
Power over Ethernet (or PoE) is the delivery of electrical power to networked devices over the same Ethernet cabling that connects them to the LAN. This simplifies the devices themselves by eliminating the need for an electric plug and power converter, and makes it unnecessary to have separate AC electric wiring and sockets installed near each device.
PoE works over standard Ethernet cable that you probably already use for your network. The only catch is that for the Type 3 and 4 PoE standards that represent the current state of the art, you need 8-pin Ethernet cable. Some older networks still use 4-pin, so check before proceeding.
PoE standards are broken down into four types, which vary based on power capacity. The original IEEE PoE standard (802.3af-2003, now rebranded as Type 1) specifies how to deliver up to 15.4W of DC power per switch port to each device at up to 33 feet over Category 3, 5, 5e, and 6 Ethernet cables.
HDMI over Ethernet, also called HDMI over IP, uses an existing ethernet infrastructure to distribute HD video signals from one source to an unlimited number of screens. It can be used in many setups like point-to-point extension, one-to-many distribution, and video wall processing where video can be scaled from different .grid layouts. Video signals can be switched from any source to any screen, overcoming distance limitations of traditional CATx video extenders.
IP extension is a way to extend your video signals over long distances. Using AV/KVM extension technology to transmit lossless compressed video over optical fiber cables enables video extension of resolutions up to 4K@60Hz across very long distances today. This method provides enough bandwidth for high-resolution DisplayPort 1.2 video signals, keyboard/mouse, USB 2.0, RS232 and audio.
High-end AV over IP systems installed in stadiums, for example, can utilize compression algorithms such as H.264 to send packetized data over increasingly long distances. Such compression shrinks the signal delay down to an unnoticeable two or three frames per second. This gives the spectators an enhanced experience by viewing live or edited video content.
Discover how Black Box's HDMI Converters and Scalers offer instant conversions from digital HDMI to analog Component/Composite video with either analogue stereo audio or SPDIF digital audio. With these converters, analogue video receivers such as TVs or external TV receivers can be readily connected to HDMI sources such as DVD players or video game consoles.
AV and KVM extenders play an important role in overcoming bandwidth and distance limitations of VGA, HDMI and DVI, as well as PS/2 and USB cables. Classic (direct connect) KVM extenders transmit video signals via fibre or CATx over long distances (CATx up to 100m, fibre up to 10 kilometres).
IP extension is a way to extend your application over long distances. The technology is flexible, future-proof, and gives you the option of using either CATx or fiber optic cabling, depending how far you want to go and which signals have to be transmitted. IP-based extenders usually send data over a 100m (330 ft.) segments, but you can extend farther by using Ethernet switches as repeaters. If fiber cables are used signals can be extended up to 16 km (10 miles).
Black Box offers HDMI over-IP extenders that enable you to transmit HDMI video and audio over an Ethernet network to a virtually unlimited number of screens as far as your network reaches. Like this you can extend audio/video from one source to a single screen (unicast) or distribute (multicast) the same content to multiple screens.
High-performance KVM-over-IP devices transmit video and peripheral signals using a standard IP network, providing fast visual access and sharing of peripheral devices such as keyboards, mice, tablets and storage devices. Video signals are typically compressed (lossless) to accommodate for the bandwidth requirements of the application and network infrastructure.
When high-performance KVM-over-IP solutions such as Emerald Unified 4K KVM are connected to virtual servers, they provide zero-client-based, real-time access at very high image quality, preserving the desktop experience that users get from a local PC. This helps to increase workflow efficiency, response times and productivity without the expense of consuming more bandwidth.
HDMI Ethernet switches and matrix switching solutions, also called HDMI over IP switches, allow switching HDMI video signals between multiple sources (e.g. content players) and displays over IP. Connect multiple sender and receiver units with a dedicated Gigabit network switche to create a custom matrix. Or use a transmitter and a receiver as a point-to-point (P2P) extender by connecting them directly through a single CAT5e/6 cable.
Black Box's MediaCento Video over IP solution enables you to multicasts HDMI video and audio to up to 256 screens on a single Ethernet network, making it the perfect solution for distributing high-resolution digital signage content or other HD video and audio.

While HDMI to IP encoders allow to convert HDMI video and analog audio input signals to H.264 for streaming over an IP network connection, HDMI to IP decoders decrypt the compressed IP data stream to display it on a remote output device. These devices are also reffered to as IP streamers when used with specific codecs.
Black Box's VS2000-DEC H.264 Encoders/Decoders encode/transmit and receive/decode high-quality video over a standard IP network. Because the decoder uses H.264 compression and requires very low bandwidth, it's extremely efficient when decoding full HD video and analog audio. It also supports AAC audio encoding so a high-quaility audio signal can be delivered at low bandwidth requirements.
Black Box helps companies design, integrate, and maintain reliable AV and KVM solutions for broadcasting, post-production, stadiums & arenas, medical, air traffic control, oil & gas, government & military, and utility industries. Leave the tech to us and our comprehensive technology solutions will deliver secure connections, fast-response times, real-time collaboration and more.
We have a wired Voip phone that was recently moved to a different wall across the room. When you plug it in to the ethernet port, it powers up and receives power from the POE switch. However, it fails to see the network or receive data. When you move the phone to another working port, it receives data and works great. I've never seen a port give power and not data. Any ideas?
FCoE (Fibre Channel over Ethernet) is a storage protocol that enables Fibre Channel (FC) communications to run directly over Ethernet. FCoE makes it possible to move Fibre Channel traffic across existing high-speed Ethernet infrastructure and converges storage and IP protocols onto a single cable transport and interface.
I have a situation where I run a local network between two computers over an ethernet router. The ethernet router is not connected to the internet, but the wireless network is. I would like to be able to stay online, even when I am connected to the local, ethernet network... Is there a way to tell systemd-networkd/iwd/systemd-resolved to prioritize wifi over ethernet for internet, while maintaining the ethernet connection? I use iwd, systemd-networkd and systemd-resolved for my network needs. I tried setting RouteMetric to different values (I assume a lower value has a higher priority) but this didn't seem to work.
Each IP camera has a budget, the minimum power required over Ethernet for it to function. When considering suitable switches, check the budget per port to ensure that it is sufficient to power your IP cameras
PoE (802.3af) is the original PoE standard and offers 15.4W of power to the Ethernet port PoE+ (802.3at) is the latest standard which almost doubles the available budget, providing 30W of power to the Ethernet port and futureproofing your network with the latest power over Ethernet standards.
Also, if anyone has a better idea, I'm all open to it! I think I could even potentially put a different cable or install other cables if needed, but that would probably make it more complicated and is maybe an overkill...
