I've changed, I've tried different temperatures from 206 to 210 degrees Celsius. That's not too much. You may vary temperature a bit more, but don't go over 230°C for PLA.

Do you use the default temperatures for the 0.4mm and 0.6mm nozzle or did you change those values in the firmware?

Well the spamers maybe too...

uhmm... would you mind posting rather different topics in different threads? People who come later with maybe the same question find the answer much easier if you separate the topics.

Search a bit this forum for the two. I guess you will find that with the Mark2 you have a wide spread community for support which might not be the case for the other option.

Damit der Druck sicher auf der Druckbettplatte klebt und sich nicht ablöst (könnte z.B. eine Rolle spielen, wenn man auf ein UM2GO ohne beheiztes Druckbett druckt ) empfiehlt es sich, einen soliden Brim dabei zu drucken.

I think you're quite well off with the CPE profile for XT. From there it should not be so difficult to adjust for nGen. Have also a look at http://learn.colorfabb.com/how-to-print-with-ngen/

Do you mean testing our products (materials, hardware, software, how it all works together, and work with new things), or certifications like CE? Those are 2 quite different.. Well if you ask me like that: first one and then the other...

You don't even have to buy it - just use the PVA solution you get from postprocessing your UM3 prints with PVA.

You mean the belts? Sure. Please contact your Ultimaker reseller. He should be able to get them for you if he does not have it on stock.

Ultraschall bringt nicht viel beim Auflösen von PVA, da es das Wasser nur hin- und herbewegt. Entscheidend ist aber, dass immer wieder "frisches" Wasser ans PVA gelangt. Das bedeutet, dass die PVA-Konzentration im Wasser beim aufzulösenden PVA möglichst tief gehalten werden sollte. Am besten erreicht man das durch ein Bewegen des Wassers. Zusammen mit dem Temperieren des Wassers beschleunigt das den Auflösungsprozess. Am besten eignen sich daher Aquarien und Sous-vide Garer.

Someone from testing? This can be internal testing, beta testing, official measurements for certifications (e.g. EMC) etc.

+1 Cura Maybe not for the next but what about an AMA with one of the founders? Also, an AMA with someone from Sales/Distribution might be interesting. Or from support!

Doesn't sound like normal behavior at all. Please contact your reseller.

Then I suggest you compare the temperature and speed settings of Cura and Slic3r.

@adamgarb: The only printer Cura has an active connection to is the Ultimaker 3 afaik. In order to set up a printer you have to select one of the presets or set it up by yourself as a custom printer.

Maybe you want to clean the hotend as it looks like a partial clog to me. Make sure no leftovers from e.g. ABS are in the hotend when printing PLA. I recommend you start with a series of cold pulls.

Conductive filament has a conductive element admixed. Such admixtures (powder, fibres etc.) are quite abrasive. I would indeed recommend a special nozzle but avoid maybe steel or similar and go for a ruby nozzle, e.g. the Olsson Ruby.

Du sprichst ein paar gute Punkte an. Tatsächlich wäre eine saubere Dokumentation verschiedener Netzwerk-Konfigurationen sehr wünschenswert. Dazu gehört sicher auch die Variante der statischen IP-Adressen wenngleich diese Variante erfahrungsgemäss von sehr wenigen Benutzern gewünscht wird; die überwiegende Mehrheit arbeitet heute mit WLAN-Routern welche problemlos DHCP unterstützen und für bestimmte Mac-Adressen auch IPs reservieren können. Die statische IP-Variante kommt am ehesten drahtgebunden in Labor-Netzwerken vor. Da wäre eine Anleitung für fachkundige Benutzer tatsächlich angebracht. In Cura gibt es effektiv einen Schluckauf beim Verbinden. Wenn die automatische Erkennung nicht funktioniert, so hilft es, "Hinzufügen" auszuwählen und dort die IP-Adresse des Druckers einzugeben. Dann erscheint er sofort in der Liste. Wie Du richtig bemerkt hast, ist die UM3-App leider z.Z. nicht auf einem Stand, der die gesamte Konnektivitäts-Funktionalität sicherstellt.

If the Mark2 works with G10/G11 it should take the values from the printer settings. Otherwise retraction recognition (the feature is called somehow different) in Marlin would have to be enabled to be able to change it on the printer. If none of those is true, Cura handles the retraction settings.

In addition to the test model you use for testing a new material, can you describe shortly how a new Cura material profile is produced? What kind of test and results are needed before UM can distribute the profile? If this exceeds this AMA, it might also be a nice topic for a blog...

In addition to cleaning the outside, wouldn't it be better to avoid the nozzle dip into the PVA prime blob at the the beginning of the print?

And as also mentioned already on Twitter, can you maybe comment on the outdoor capabilities of some other UM materials too?

Here you find the assembly manual as part of the source files.

How did you get the old motor working with the new feeder? It should lack the cog... the new motor including this cog should be available from your Ultimaker reseller.
