    Any news on the I180 and the Material Station?

     

     

    That is a question you probably would have to ask to igus since it's the manufacturer who decides if a material should be made compatible with the material station.

  2. Afaik the firewall only blocks internal network prints atm but not the USB port.

    I would probably use a seal sticker on the front panel.

    A more radical approach would be to disconnect the USB connector from the mainboard. For that you would have to open the bottom of your S3. You would do that in your own responsibility.

  3. Please be aware that the development of Cura by Ultimaker is focussed on Ultimaker 3d printers. I assume you use Cura with a third party printer. In such a case the open-sourceness is key. That means, the creator of that printer profile or the manufacturer of the printer (which would be the same in an ideal case) should care about the USB connection by Cura.

    In case you try to print through USB from Cura to an Ultimaker printer: it's not recommended, please use the sd card or Octoprint instead.

  4. There might be an alternative.
    If you bought that S3 after April 2020, it came with Ultimaker Essentials, the entry level Ultimaker software plan. Part of that plan is Ultimaker Cura Enterprise. That is a security-checked version of Ultimaker Cura that updates twice per year and gets official support for the last two versions from Ultimaker. That means, your IT department could install that Cura version and would only have to update it once per year (except for urgent bug fixes).

  5. The flow error is displayed if the measured flow is smaller than 80 percent of the flow defined by the print file.

    If the end of the filament is still 10cm away from the nozzle, somewhere inside the Bowden tube, it might flow with almost 100 percent but still you would have no extrusion. The sensor measures the flow through the feeder, not through the nozzle.

  6. Make sure you have the newest firmware version of your update channel installed. IIrc there was a recent update concerning the flow sensor during loading.

    As for no filament coming out of the nozzle: the sensor only detects the (in)correct flow but can of course not detect if the filament is at the wrong position (e.g. due to an early confirmation at loading).

    The belts do not need to be tensioned by you (except for the short belts on the motors if you ever remove those). The long belts are tensioned automatically by springs in the sliding blocks.

    Though one should allow those springs to tension the whole belt and not just the half that goes through the sliding block from time to time: https://ultimakernasupport.zendesk.com/hc/en-us/articles/115004168883-My-Long-Belt-Is-Loose

  8. You can easily achieve this with a S-line or 2+ Connect printer, the Digital Factory and an Ultimaker software plan like Ultimaker Essentials. Essentials comes with every new Ultimaker printer. If you already have an Ultimaker printer and don't need another one in forseeable future, please get in contact with your reseller for a seperate Essential license.

    You then can share a printer among individually selected people (teams) or with your whole organization, i.e. everyone you invite to sign up for a (free) Ultimaker account and to belong to your organization. On the S-line printer you can enable the firewall which restricts access to only Digital Factory access and disables direct network access.

  9. Der Filamentsensor des Ultimaker S5 basiert auf einem Encoder-Rad; das sollte auch mit komplett transparenten Filamenten kein Problem haben. Ich habe bei mir noch nie ein Sensor-Problem spezifisch mit PVA festgestellt.

     

    Im konkreten Fall von @Hering95 würde ich mal untersuchen, ob ev. irgendwo ein erhöhter Widerstand vorliegt. Wenn es nur bei PVA ist, dann würde ich mir zuerst den BB-Printcore vornehmen (Printcore-Cleaning mit Cold Pulls). Besagte Fehlermeldung kommt immer dann, wenn der Ist-Fluss unter 80% des Soll-Flusses fällt. Das kann auch bei einer teilverstopften Düse der Fall sein.

    Und natürlich sollte das PVA in einwandfreiem Druckzustand sein; im Zweifelsfall gerne mal 24-36 Stunden bei 55°C ausheizen.

    Vor einiger Zeit habe ich mal versucht, alles Wissenswerte über das Drucken mit wasserlöslichen Stützmaterialien zusammenzufassen: https://www.dim3nsions.ch/news/drucken-mit-wasserloslichem-stuetzmaterial

  10. Apart from cleaning the connector pins on the printcore pcb there is not much you can do about the printcore. And of course make sure the printcore is fully inserted into the slot but I assume you did that.

    What I find a bit strange is that you don't get a heater error when you try to manually heat the core - how long did you wait?

    You may also try to re-install the same firmware again to overwrite some potential typos from the active-leveling-disabling-procedure.

  11. An elephant foot is usually the result of an overextrusion or a too high temperature (and therefore a too low viscosity) on the first layer. Those should be the parameters to adjust for getting rid of it. From second layer on, no overextrusion should happen if e.g. the flow on the first layer is reduced a bit. Therefore I don't see a need for a second layer horizontal expansion adjustment for a well adjusted print profile.
