Printer stoped. Conection closed

iancarrasco

Hello. I installed Ubuntu and Repetier Server on my Orange Pi Zero 3. I loaded the backups of the 3D printers that I had on another Orange Pi and set everything up. However, the problem I'm having is that whenever I try to print, regardless of the printer, I encounter the same issue. It starts printing, but then randomly stops. Sometimes, the print gets stuck, only laying down a few lines before getting stuck again, repeating the process. Other times, it just stops altogether and doesn't work anymore. These are the errors that the different log files are throwing:

I see 2 things. Problem onw seem
2024-03-24 02:35:15: (B1) Ender-3 Max - H2: syslog: [ 251.488734] ch341-uart ttyUSB0: usb_serial_generic_read_bulk_callback - urb stopped: -32
which might be the reason you get communication issues. Then you have usb reconnect on timeout set and I guess it is on early so server tries to recover the connection be resetting the usb line, which is why linux restarts driver after you see

2024-03-24 02:35:15: usbreset: /usr/bin/sudo /usr/local/Repetier-Server/bin/usbreset /dev/serial/by-path/platform-5200000.usb-usb-0:1.4:1.0-port0

So first try setting it to never to see if this is the ugly reason why we implemented it - driver crash due to communication errors. If it just gets an error and continues it should stay that way. If it hangs until you reset usb manually it is required and you should check if there are sources of electric interference or unstable power for pi (see bolt menu in server if you had undervoltage). These can improve likeliness of errors.
