after job start i lose the connection



  • I have a problem with two duet2 ethernets of around 20 installed.

    When I start a print job, it loses the connection to the webcontrol shortly thereafter and can only be found again after the job.
    sometimes only when the printer has been reset.

    ping does not come, even though the display shows an IP.

    I then updated to the new firmware and still have the same problem.

    I ask for help.

    regards
    Michel



  • Sounds like electrical interference. What troubleshooting have you already done? Changed/swapped/moved ethernet cables? Are all machines identical, and config.g the same? If so, if you swap one of the problem Duets to another printer, does the problem follow the board or stay with the printer? If you can run M122 after reconnection (or immediately after reset), and post the response here, that may help.

  • I have already switched from 1.22.6 to 2.04.

    I produce printers and always have the same config and firmware on them.

    Lan cable is certainly not a problem since I have tested it on other printers and there are no problems.

    If this is a guarantee case, I will be happy to discuss this with roland.
