  1. Here is a positive update; the DNS configuration error that has been plaguing us for some time has been fixed. No more aws url's. Sharing a reply, logging out works again as normal.

    It does not if you select the online documentation menu item in Cura. At least not for me.

    This one is a very good example for the unnecessary travel moves in Cura. IMHO there should be one travel move going to that circle and one leaving it again. Similar travel movements should occur for that infill in the front left corner. Second best way to do it would be to finish the inner walls except the innermost, then travel again to that spot, finish the innermost wall and right after it the infill. Best way to do it would be to print this area as a part of the second innermost wall line, printing something like as spiral for the remaining inner wall lines with the infill following before returning to the other inner wall path. Only very small travel moves would be necessary.

  3. If Cura would not be so obsessed to finish all lines of the same type (outer wall, inner wall, infill, in uninterrupted sequence, the major part of those excessive travel moves could be avoided. Advantages would be an improved printing time and a lower risk for a travel move to detach already printed lines. And of course one would get of the ugly combing lines which can atm only be done by adding retraction and z hop which needs additional time.

  4. Yes, a humidity warning sticker on the PVA spool would not be wrong. But I think it's quite logical that a material which dissolves in water is sensitive to humidity.

    UM PVA should now come with an additional resealable bag, at least the last 350g spool I opened had one inside the packaging. However that bag is not included in the printer package.

    Speaking of the 350g PVA spool: that one exists exactly because of that sensitivity to humidity. People who don't print a lot are better off with the 350g than with the 750g. If an UM3 is used professionally and running for a large amount of time it should be possible to use 750g in a quite short time.

    Anyway, if PVA is not printed, take it off the printer and store it in a sealed bag with dessiccant.

    You can use PVA also with ABS and PC but more or less it's safe to say that ABS or PC stick fairly on PVA but not the other way round. It depends a lot on the geometry.

  5. Ich habe mir ein Stück Karton zugeschnitten, das genau die Grösse des Heizbetts hat. Das lege ich z.B. für PC auf die 4 Clips und verhindere damit einen Grossteil der Strahlungsverluste. Geht deutlich schneller als ohne.

    Für die eingeschränkte Heizleistung gibt es verschiedene Gründe. Der wichtigste ist sicher die Leistung des 220W-Netzteils. Dieses ist das grösste mit dem verwendeten Stecker, stärkere Netzteile haben einen anderen Stecker. Diese Steckeränderung hatte stattgefunden als der Ultimaker 2 damals kurz vor der Vollendung stand. Damit war die maximale Leistung besiegelt. Dass Ultimaker so lange wie möglich beim gleichen Netzteil für möglichst viele Geräte bleibt finde ich nachvollziehbar. Daher auch die Beschränkung beim UM3.

    Andere Gründen dürften auch normentechnischer Natur sein. Eine 230V Heizung geht natürlich viel schneller, ist aber auch elektrisch anders zu behandeln als einen Gleichspannungsquelle.

  6. What upgrade kit do you mean? The dual extrusion upgrade kit for the Ultimaker Original? Don't use that one on an UMO+! The temperature sensor is different (thermocouple vs. pt100 on an UMO+) and if you use that heater cartridge which is made for 12V iirc with 24V you will heat with four times the power, i.e. with 160W (good way to burn down your house).

  7. I guess you will have to wait until the Cura devs introduce the functionality the TweakAtZ plugin had, i.e. to change a certain setting like the fan speed at a certain height.

    This should imo be part of the Curaengine, including the possibility to change the layer height at a certain height as e.g. Simplify3D allows for.

  8. 1)is the spool itself clear or black? the spools that are working for you, and the spools you got with the printer are clear. i am interested to know what the spool is like you bought.. i am guessing the spool color is black (i really am talking about the color of the spool, not the filament) and i think you got it in a brown box..

    If it would be an old UM spool without NFC tag one would not see the NFC tag id with the nfc reader test.
