How can I configure mjpeg camera for K1 in GuppyFLO

[peak igloo]

@drifting ravine We've talked about this few day ago, and I've been looking at these docs: https://guilouz.github.io/Creality-K1-Series/helper-script/guppyflo/ where it is an option.
How can I get it to work?

If you already have your printer added, you can remove it and readd with the above camera configuration

Do you know the api path and port to your camera service for mjpeg? If you use the helper script to setup moonraker/fluidd/mainsail, the service is mjpeg-streamer, camera port should be 4408 for fluidd and 4409 for mainsail. Give the above picture setting a try, ip should be 127.0.0.1 in this case too.

[peak igloo]

I know the details, but I can't get anything else than go2rtc to show up

I've installed it on a separate lxc container on a different host on the same network

how can I update it?

I already installed/configured it a few days ago

I guess that's because I have an old version and need to update?

[drifting ravine]

You need to stop the service delete guppyflo dir and reinstall

sorry the installer doesn’t handle update yet, will fix that soon

[peak igloo]

can I keep the config somehow, to not have to reenter API keys, etc. ?

[drifting ravine]

yeah

save guppytunnel.json before you delete

And move it back into the dir after you reinstall

If you’re using ngrok for mjpeg streamer I suggest you not because your 1gb bandwidth from ngrok will get use up in like 5 minute of streaming

[peak igloo]

ok, so should I just remove ngrok settings?

[drifting ravine]

you can keep it, both tailscale and ngrok can be enable at the same time

Just make sure when you access via ngrok you don’t click on the cameras to start the streams

Unless it’s webrtc

[peak igloo]

Cam doesn't work for me. I've checked the url in the browser (http://<printer's ip>:4409/webcam/?action=stream) and it works

I've put /webcam/?action=stream in endpoint, ip adddress in IP address, selected mjpeg, but it shows broken image icon

also file-> remaining time

[drifting ravine]

Can you share the printer config in guppytunnel.json

[drifting ravine]

Heh will look at that metric calculation, it will tick up.

make sure you don’t share your ngrok tokens

[peak igloo]

for some reason the json has ONLY tokens, no printer config

I'll just nuke it and restart the service I guess

[drifting ravine]

I have some new changes committed but not release to better handle editing printer and camera and stuff

will release once I wrap up some other stuff

[peak igloo]

{"printers":[{"printer_name":"K1","moonraker_ip":"192.168.101.178","moonraker_port":7125,"cameras":[{"id":"camera-1405468725","path":"/webcam/?action=stream","camera_ip":"192.168.101.178","camera_port":4409,"type":"mjpeg-stream"}]}],"guppyflo_local_port":9873}```

and that url works

[peak igloo]

that's broken regardless of whether I'm accessing gf over local IP or tailscale

[drifting ravine]

hmm any backtrace in guppyflo.log? Do you see a message along the line of “Creating routes for camera”

[peak igloo]

2024/03/29 23:41:44 error coding pstats json: cannot unmarshal number into Go struct field .result.Status.print_stats.info.total_layer of type string keeps repeating

every 3 seconds

ok, that was browser's fault

Doesn't work in Edge, does in Safari

¯_(ツ)_/¯

[drifting ravine]

camera still not working?

[peak igloo]

It is working in safari but not edge on macOS

[drifting ravine]

cool I tested on chrome so that’s basically ms edge, will give edge a try later

[drifting ravine]

Probably need to ignore or add the layout fields into my go struct def, I tested without the layout stuff config probably

[peak igloo]

Just a side question: the installer script from https://github.com/Guilouz/Creality-K1-Series says you can't install KAMP when you're using GuppyScreen. Is the same thing really included in it?

[drifting ravine]

I have no idea, guppy screen doesn’t install anything kamp related. Not sure what the conflict might be.

[quiet belfry]

KAMP should be only a collection of macros and only need a few requirements that shouldn't interfere with any other software:
https://github.com/kyleisah/Klipper-Adaptive-Meshing-Purging?tab=readme-ov-file#requirements

[drifting ravine]

@peak igloo got something cool for you. Auto mjpeg streamer camera detection if you every need to setup more cameras in GuppyFLO

[peak igloo]

I've confused shape calibration scripts with KAMP 🤦‍♂️ which is actually easily installable using this script 😉

[peak igloo]

That's nice but not necessarily for me - I can set that up manually 😉 And I'll use anything else than mjpeg if I can avoid it 😉

it's a shame no one is willing to work on the adjustments for the new revision of Creality K! camera

as for me I don't think I really need to use GuppyFLO - I already have a Tailscale tunnel connected to my home subnet (at the router level), and my phone already used VPN on demand when I disconnect from home Wi-Fi

I don't think GuppyFLO really offers anything I'm not getting with that, does it?

[peak igloo]

but that will definitely be useful for people who don't, and don't know how to set that up, so thumbs up:)

[peak igloo]

@drifting ravine does GuppyFLO make sense for me to use in that scenario really? I'm using Mobileraker, can GuppyFLO provide any kind of remote access without having to connect to VPN (tailscale in my example) when using mjpeg camera?

[drifting ravine]

Not really the ngrok option used OAuth to secure access (no vpn needed), and just don’t think Mobileraker supports OAuth. Even if it does, streaming mjpeg will eat up the 1gb free bandwidth.

Why not use tailscale? It’s pretty simple to connect and disconnect on a mobile device before opening up Mobileraker.

[drifting ravine]

Maybe you can also explore other options outside of what GuppyFLO current offers. I know of cloudflared tunnel and tailscale funnels which are similar to ngrok. Cloudflared tunnel has OAuth before you need to setup a domain with them. Funnel doesn’t have built in auth so you’re relying on an obscured URL for access discovery.

There are ton actually, but my guess is anything that’s free and not p2p will not like you streaming video over their network.

[peak igloo]

I am using cloudflared for a few things, that might be a good idea. But I would need to up my authentication to expose it that way

I wanted to do it using obico tunnel (cause I'm already self hosting it), but the documentation for it (setting up the tunnel) is rather poor

and tailscale is fine, just hoped I could do it in a more seamless way.

[drifting ravine]

will take a look at what obico tunneling does

[drifting ravine]

So from my understanding of how self hosted obico works, you’ll still need to expose that server to the world. Obico does it for you in their hosted solution. But if you’re are self hosting you need to expose the self hosted obico-server (so you end up with the same situation of how you want to securely expose it)

To briefly summarize how obico works:

1. you install the obico client for moonraker/octoprint and register your printer.
2. This talks to the obico cloud, some auth exchanges and assigning a unique printer identifier
3. This registration enables your printer to talk over websocket/http to the obico server (this connection is initialized from your printer to obico and kept alive)
4. When you add your printer in obico apps, they can now tunnel data, printer <-> obico cloud <-> your clients
5. If you replace obico cloud with self hosted obico server, you need to figure out how your client will talk to that self hosted server (back to tailscale, ngrok, cloudflared, open port and etc.)

[peak igloo]

I can manage that. THe benefit of obico is that it puts some authentication in front of that too

I have been able to install the self hosted one, and access it both remotely and locally, but couldn't get the tunnel to work

for additional security I could try putting it behind cloudflared instead of Nginx Proxy Manager. But I need to figure out how to do NPM first

[drifting ravine]

What do you mean it works locally and remotely if you can’t get the tunnel to work? If the tunnel doesn’t work then what works remotely and locally? Your auth is basic auth, your server is handling it, so any attempt to DOS or exploit, it will be handled by your server instead of a third party like in oauth before allow access. I’m not fond of exposing a self hosted server which handles its own authentication and is part of my local network.

[peak igloo]

SO the WebUI for obico works, but klipper tunnel (which should tunnel moonraker for me) doesn't

I'm not fond of exposing it either. So once I get the basics working I'm planning on moving it to a cloudflare tunnel for some additional protection against attacks like DOS. I know it won't protect it from all exploits.

[peak igloo]

https://www.obico.io/docs/server-guides/tunnel/

https://obico.io/docs/user-guides/moonraker-obico/config/#tunnel-section

and right now I've detected an entirely different configuration issue with it that I posted about in https://discord.com/channels/614543405724205137/648759742881071124

[drifting ravine]

why not just expose your reverse proxy that’s hosting your moonraker/mainsail through cloudflared then? Is obico mainly for ai detection in your use case?

[peak igloo]

I thought about exposing moonraker via NPM, but that's something that might be less secure than Obico itself?

I don't know how much is moonraker being tested against being exposed to the internet

that's a solution designed to be used in that way

if someone tries to abuse moonraker that's on my printer it may actually affect my prints (performance of k1 isn't greatest) whereas doing the same to the server where I have obico probably won't do much

[drifting ravine]

no idea, don’t have context either. Just my 2 cents, I trust cloudflared/tailscale to do auth then a self hosted server

[peak igloo]

tailscale is probably the most secure option. Cloudflare tunnel is definitely more secure than just exposing a site via NPM with HTTPS, but doesn't avoid possible flaws in the service you're exposing. I feel like (and this might be unfounded) that obico is designed for this use case (being exposed to the web) and being patched with that in mind. I don't thing developers of moonraker put that much effort into supporting this use case. Yes, you can limit by addresses, use an API key (that shouldn't be able to be intercepted via HTTPS), but I think that's not the use case theyre actively taking interest in, if you know hwat I mean.

They have this feature, I'd like to try it out with mobileraker, so I don't have to rely on running tailscale all the time to access stuff remotely

[peak igloo]

Hey, since yesterday I've stared having problems with guppyscreen. It stopped refreshing/responding to touch. Restarting it sometimes helps.
This is what I'm seeing in the logs:

terminate called after throwing an instance of 'nlohmann::detail::type_error'
  what():  [json.exception.type_error.302] type must be string, but is null```

the only thing I remember doing since then is...adding filament to spoolman

I found that the filament I've added had no filament type (PLA, PETG, etc.) added could it be that?

[peak igloo]

It seems like that was the issue. That field is not mandatory in Spoolman, so I guess guppyscreen could do some validation? I’m not a developer, so can’t really help with it though:/

[drifting ravine]

Yeah I just committed a fix yesterday

Will make a release when ready

[peak igloo]

Thanks!

It’s not like I will hit it again, but hopefully someone else won’t:)

[peak igloo]

Hay, I'm getting klipper shutdown, when running Guppy shapers gcode macro:

{"code": "", "msg":"MCU 'mcu' shutdown: Move queue overflow", "values": []}
21:40
{"code":"key60", "msg":"Internal error on command:GUPPY_SHAPERS", "values": ["GUPPY_SHAPERS"]}
21:40
{"code":"key60", "msg":"Internal error on command:TEST_RESONANCES", "values": ["TEST_RESONANCES"]}
21:40
Klipper state: Shutdown
21:40
Testing frequency 58 Hz
21:40
Testing frequency 57 Hz

sometimes on the forst pass, sometimes on the second.

[primal meadow]

@peak igloo please fix your tags as the bot mentioned. this is a webcam related issue so please remove the wrong tags...

[peak igloo]

Can’t see that option on the mobile client

[primal meadow]

fixed it for you. its a bit tricky on mobile and i don't know if there are any differences between android and ios

[quiet belfry]

This whole thing was a mix of different things all connected to guppy stuff, so I let it like that. The title is a bit misleading here

Mostly related to guppyflo

[drifting ravine]

My understanding is that mcu error are usually due to the board overloading. My only suggestion for these cases is skipping the graph image generation. Or see if there are other non critical services you can kill off.

[peak igloo]

Thank you
