Fetching Printer... No Connection

[St1fT]

Hi,
Mobileraker connect to my Printer, but the Dashboard shows "fetching printer..."
My Config part is: */printer_data/config/
I don´t know, if this is the issue.

[akno2205]

Sorry, I didn’t expect that it is so long. All my other printer with the old config path (klipper_config) are working well. The detail were shown in the app. I run the latest release of Klipper.

[Clon1998]

I will have a look at that once my only Klipper printer is back up running. Otherwise it's hard for me to reproduce it.

[akno2205]

Thank you for the fast reply.

[klHaribo]

I have the same error.
printer worked fine with mobileraker.
until I changed my setup to dual color, this error came up.
I am now on the last version from github

[Clon1998]

I currently don't have time to look into that since I have a few finals coming up the next week's.
I am pretty sure there is a issue with the config parsing?

[klHaribo]

I am not a programmer, but I can take a look at it in the next days. I am also very busy :)

[Clon1998]

Just noticed that this issue is related to #97, or at least the problem @akno2205, @klHaribo encountered.

I just fixed that issue, as mentioned in #97 a new app version 2.1.1 should be available in the next few hours.

[Clon1998]

However, this does not resolve the issue the original author @St1fT has AFAIK.

Therefore, I will look more into that once I am done with my exams in the upcoming weeks.
If I forget it, don't hesitate to ping me again @St1fT !

[freeblazin]

I am also experiencing the OP's symptom. Dashboard shows "fetching printer..." indefinitely. Console commands and emergency stop from app are working as expected, confirming connection to moonraker api is good. I am also running the latest moonraker version with changes in config directory structure to "`/printer_data/config/". I tested mobileraker v2.1.1 with no change in symptom.

Hope your exams went well good sir!! Let me know if I can support any other testing or data/log gathering to support when you get around to looking into this.

Are you by any chance using iOS?
If that's the case can you try the latest beta:

https://testflight.apple.com/join/h9JwuyR0

And if it is not working, can you send me the log files that are accessible at the bottom of the Settings page?

[freeblazin]

I am using Android app version. Looks like there are no log files in the settings page for the Android app. Is there another way to access the app logs?

Can you try to join the beta program on PlayStore?
I just double-checked it and by now, google should have approved the latest build (2.1.2-126) for the public.

Hey thanks for the log, I will look into that.
Regarding the message [ [38;5;12m💡 No remote client configured... can't do handover! ref:92050206 [0m], this message simply means that no OE client is available for usage in case the current local client is unable to connect to your machine. However, as the log entry [ [38;5;12m💡 [516785204-ws://192.168.2.119/websocket] ClientState.connecting ➝ ClientState.connected [0m] shows, your local client is working fine and therefore this has no influence.

I had a brief look at the output, it seems like the app gets stuck during the parsing of the cached temperature data.
Can you do me favor and send me the output of the following web-request in order for me to debug/reproduce it locally:

1. http://192.168.2.119/printer/objects/list
2. http://192.168.2.119/server/temperature_store

[ripinteer]

Thanks for explanation. One more thing, I remember that I faced this problem last year. Unfortunately, I was busy studying, so I didn't report the problem then.

---

As for the jsons, here they are:

temperature_store.txt
list.txt

I changed .json to .txt, cause github don't like it for some reason.

I will plug the json directly into some of my code and see what happens.

I think I already found the issue!
Is there any reason to why you did not configure any heater_bed?

[ripinteer]

I think I already found the issue!

That's right, I have my test bench on my table, and I removed heater_bed from config, so Klipper won't complain :)

Alright, I will hopefully have some time today to remove all of my hardcoded heater_bed references that are causing/will cause errors!

[ripinteer]

Hooked up the bed and config piece)

[Clon1998]

Fixed in 2e598ee!
Should be available in the stores in the next 24-72hrs.
For Android users, feel free to sideload the app via GitHub !
