UM3 Starts printing from unknown source

Recommended Posts


my UM3 is located inside a medium size company and I had the problem that the printer starts printing from an unkown source. I asks the colleagues that are also working with the printer, but nobody of them started the job. Is it possible to see the IP-Adress or something else to find out the source of the job?

The API shows an empty user:

  "datetime_cleaned": "",
  "datetime_finished": "2018-01-04T12:52:44",
  "datetime_started": "2018-01-04T11:40:51",
  "name": "S_Csword-90",
  "progress": 0.23807909949339073,
  "reprint_original_uuid": "",
  "result": "Aborted",
  "source": "WEB_API",
  "source_application": "Cura connect",
  "source_user": "",
  "state": "post_print",
  "time_elapsed": 2913,
  "time_total": 12238,
  "uuid": "642a2cef-0224-483b-90b8-fbe66fc67e14"

Kind regards,

I figured out that an other colleague of mine has an Ultimaker 3, too. And to any reason the job starts on the wrong printer. This is very strange and I expected that every user has to get access (by pressing the button in the frontpanel of the printer) before printing is possible.


Anybody else with more then one UM3 has the same problem?

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
