Arrêt brutal durant l'impression
Bonjour,
Repetier server 1.0.3 est installé sur une raspi3 à jour. En cours d'impression (sur Alfawise u20 en marlin2.0.x), l'impression s'arrête brutalement. Je n'avait pas le problème avant. J'imprime le même gcode depuis la carte sd sans avoir d'arrêt brutal.
Quel peut être le problème ?
Merci

Hello,
Repetier server 1.0.3 is installed on an updated raspi3. While printing (on Alfawise u20 in marlin2.0.x), printing stops suddenly. I didn't have the problem before. I print the same gcode from the sd card without having a sudden stop.
What can be the problem ?
Thanks

J'ai donc 2 alimentations 3A, 2 câbles USB 2A (1 pour la raspberry, 1 pour l'écran tactile). Je vais testé avec une autre Raspberry PI3.
There is also an option to reset usb on timeout that helps with some printers in case it is the serial driver in linux that hangs due to some error.

What exactly happened? Did really the server restart? You need to check server.log and /var/log/syslog to see what is disturbing the prints. Always hard to say since so many things can cause print stops.
2021-03-15 18:30:58: No valid response seen within 10 seconds from printer, restarting connection
Last thing is unplug usb cable and reconnect. Would it then connect again?
The question here is mainly why do we get no more data from the printer. Depending on where the problem is different actions will lead to connecting again. It also might be that you need to reset printer to make it work again.
You can try to set in serial connection ping pong on. This reduces the risk of communication problems but also reduces maximum transfer data. But some firmwares get problems with high communication load. Others only communicate on special rts/dtr values which automatic reconnect may prevent from being set. Once we know what the problem is we can put in the correct fix.
What do you mean with shutdown? If you shutdown the server the printer will stop.
All I see here is a server start that needed some tries to establish connection and a job that was killed after 3 minutes.
You need to provide more context and time when what happens and what you saw and did. From this I just assume you killed the print as I do not see a disconnect during print.
Le serveur a planté seul, sans aucune intervention de ma part. Voici les journaux de l'imprimerie actuelle, qui a été brutalement stoppée.
Recv: 15: 57: 33.100: Erreur: le chauffage a échoué, le système s'est arrêté! Heater_ID: 0
Heater id 0 is most likely your extruder. These are the most frequent to have this error. Normally a broken wire due to all the moves and bending during print. Can be the heater or the temperature sensor. On mismatch better firmwares detect that the temperature does not react as expected and go into fail save mode. There is also the chance of a false signal if the calibration of the detection parameter is too narrow. When you enable real logging you see this in the temperatures. When they go suddenly to very hot or very cold the thermistor is the problem, otherwise more likely the heater.
