Hallo,

seit ich heute auf Version 0.92.1 update gemacht habe funktionier mein Prusa über /dev/ttyAMA0 nicht mehr.... hat die ganze Zeit ohne Probleme Funktioniert, jetzt findet er auf der Schnittstelle keinen Drucker mehr... 
ich direkt am Mainboard über RAPI/Port angeschlossen..


jemand eine Idee

Strange thing. Just tested on my Prusa and got the same. After some hours of investigating I at least found out that the checkbox "Port is visible even if printer is not running" seems to trigger the problem. Also I can connect with that setting to real usb of prusa it doe snot work with internal ttyAMA0 any more as it seems. And that also I wrote it for that case to reduce all the log retries when prusa is not enabled.

So for now you can disable that setting and I hope it is the same problem as for me. Will check what changes apart from logging with that. and will fix it for 0.92.2 coming soon.

Ok, found the problem. Fixed in 0.92.2 until then just work with the switch disabled.

Bonjour,
Depuis la version 0.92.1 Pro, je pense rencontrer le même problème, tout fonctionne sauf que le serveur ne semble pas se connecter à l’imprimante USB, je n’ai pas activé "le port est visible même si l’imprimante ne fonctionne pas" mais ça ne règle pas le problème à la maison, donc je ne peux pas utiliser ma licence pro si vous pouvez m'aider s'il vous plaît. que devrais-je faire ?? : '(L'
appareil photo ne fonctionne pas trop ..... L'adresse IP n'est plus marquée sur l'écran de ma Prusa.
Le serveur ne reçoit plus les données de l'imprimante et ne commence pas à imprimer car il est gelé
is it possible to test your version 0.92.2 to see if this fixes the problem ??  
[Prusa MK3 firmware 3.7.2]

Server 0.92.2 should come today or tomorrow depending on the last bugs I want to remove.

With these settings it should work fine. But make sure that in prusa using Raspberry Port is off or the printer can not connect over usb I think.

Settings should work also with 0.92.1 I had tested usb that way.

What pi are you using? Zero W on the board connector or external pi? I wonder because the pi zero only has one usb port and with webcam you need 2 if both use usb.

Also whcih image do you use. V15 had broken webcam support so that might also be a reason webcam does not work.

And last, please answer in english. Don't speak french and translation with google is hard to understand.

Hello,
Sorry for the automatic translation of google that has messed up in my message. I use a rpi 3B +.
Regarding the port rpi in Prusa I noticed that it was ON yesterday during my tests so I will try again by switching it to OFF to see if this solves the problem on my side and I'll let you know by 3 hours when I went home. thanks a lot for your help
