For completion sake.. downgrading to 1.5.0.0 seems to have fixed my printer. it's been reliable since. ER214 never occured again - and it stopped disappearing from the LAN, this could've been the result of deleting it from the DigitalFactory Cloud, factory resetting the printer and re-adding it to the cloud multiple times in different order - or switching to Cura 5.1. I have no clue what happened and how to avoid it in future, for now i'll stay well away from Firmware Upgrades. Ultimakers answer to my ticket was lacking any solution, but they replied fast.

Something is completely screwed up with DigitalFactory Cloud and my UM2+C. Preface this with: this used to work flawlessly for over a year.. and the only things i changed was update Cura more or less infrequently. It seems to me once i stated using Cura 5.0, the UM2+C stated disappearing from my LAN, both Cura 5 and DigitalFactory reported the printer as offline.. why a printer would drop off a cable based LAN is completely beyond me.. anyway.. In the hopes that a firmware upgrade might solve this, i let my UM2+C update to firmware 1.5.02 via the printers menu - and upgraded to Cura 5.1.0.. And now, i am well and truly stuck. For the first time, i received an ERR214 (see https://support.ultimaker.com/hc/en-us/articles/360018081180--ER214-Missing-SD-card#:~:text=If you have encountered this,the front of the printer. ) but only once, right after the FW upgrade, never again. I thought this Upgrade was meant to fix this error? For me, it seems to have introduced it. But now I can't get prints to transfer from Cura via DigitalFactory to the printer anymore. The printer reports "error receiving from Digital Factory", Digital Factory says error or failure to send. I was never a fan of this cloud b., but at least it used to work. Now it doesn't anymore. I tried factory resets, i tried deleting the printer from digital factory, i tried resetting the digital factory connection from within the printer (which according to Ultimakers FAQs is known broken? see her: https://support.ultimaker.com/hc/en-us/articles/360021112159-Having-trouble-connecting-your-printer-to-Ultimaker-Digital-Factory-) - all to no avail. I cannot print via Digital Factory anymore. In order to get some prints done, i downgraded to 1.5.0.0 (by guessing the download link - why is there no link given in the Firmware History page here: https://support.ultimaker.com/hc/en-us/articles/360017358580-Ultimaker-2-Connect-firmware-release-notes?) and at least got one print started after the downgrade back to 1.5.0.0, but this cannot be solution... How can I get a reliably working printer again? I know this is Ultimakers cheapest printer, but it feels like the step child that is mostly ignored by Ultimaker..

Strangely enough, I noticed this same behavior from UM2+Connect (sans Camera, which the UM2+C does not have).. It seems to randomly drop off the LAN for no apparent reason. Used to work just fine, just started recently. It might coincide with switching to Cura 5. Did you find out more about this issue meanwhile?

Ok, so I decided to finally add my Air Manager that has been sitting in its box for a while to my UM2+C. Maybe that was a bad idea. The printer has been printing flawless the last month or two, until I added the Air Manager. I am on latest Firmware 1.50. When I check the Diagnostics page on the printer, it reports Air Manager present, shows 23°C as ambient temperature (close enough) and I can turn the fan on and off. I started up Cura, sliced a test cube and tried to print using the Print via Cloud Option, as usual.. Looked good, nothing abnormal.. Cura says it uploaded the file successfully, but nothing happened. Print never started. The printer status remained "idle", regardless what I tried to do, no prints would start. Eventually after messing around for a while not getting anywhere, I decided to remove the printer from Cura, disconnect it from the Digital factory, delete the printer from digital factory.. and added everything back in. Good news: it is now printing again. Bad news: Air Manager does absolutely nothing. Fan is not spinning. Do I have to tell Cura that the Air Manager has been installed? I noticed that in Cura > Machine settings the box for Heated Chamber is not checked. Do I need to check this? I also noticed a checkbox "Chamber Loop" in the Cooling section. Am I supposed to check this box? Anybody got a clue what I am supposed to do?

Water based acrylics used by plastic model builders works well. The usual Vallejo, Games Workshop, ArmyPainter paints etc. I'd use a primer, yes.. couple of 3-4 coats of filler/primer spray and a bit of sanding also gets rid off layer lines. Check automotive primer spray cans. If your kid is still young enough to stick everything in the mouth, maybe even consider a food safe resin coating on top.

Möglich? Möglich ist es alles. Du musst gucken, ob das der Fall ist oder nicht, das seh ich von hier nicht. Zerleg mal das Hotend und schau, ob da Filamentreste an der Stelle sind, wo Schlauch auf die Düse stösst. Wenn ja, dann kann es sein, dass die Kupplung nicht mehr hält oder der Schlauch nie ganz unten ist. Youtuber Chuck Hellebuyck erklärt das Problem hier ganz gut ob man nun seinen Lösungsvorschlag übernehmen will muss dann jeder selber wissen.

Irgendwie verstehe ich Dein Problem nicht ganz. Es bildet sich also im Hohlraum zwischen Schlauchende und Düsenspitze ein kleiner Pfropfen, der nicht mehr durch den Schlauch passt - also beim Zurückziehen nicht mehr, weil aus der Düse raus wird wohl noch gehen? Verwendest Du nen schlauch mit kleinerem Innendurchmesser als "ab Werk"? Normalerweise klappt das Zurückziehen besser, wenn Du erst ein Stück extrudieren lässtund dann schnell zurück ziehst. Ferner wäre es vielleicht auch mal angebracht, mit ein paar "Cold Pulls" (in UltiMaker Kreisen auch "Atomic Method" genannt) Deiner Düse zu Leibe zu rücken, weil das Filamentende sieht jetzt auch nicht berauschend aus. Der Standardfehler beim Creality Hotend ist ein verrutschter Schlauch, z.b. weil die Schlauchklemme nicht richtig hält, dann hätteste auch ne schleichende Verstopfung. PS: eventuell bekommst Du in nem Creality Forum bessere Hilfe, das hier hier weder mit Cura noch mit Ultimaker Druckern was zu tun.

Ich bin dann wohl eher in der "Ich bin von Prusa enttäuscht" Fraktion. Ich hab nen MK2 und nen MK3, einen UM2+ und einen UM3. Den MK2 hab ich mir so umgebaut, dass es eigentlich kein Prusa mehr ist, erst seit dem ist er zuverlässig. Der MK3 steht noch original da, aber kann mit den Ultis nicht mithalten. Weder was die Zuverlässigkeit angeht, noch die Druckqualität. Von Joe Prusas mehr als befremdlicher Geschäftspolitik will ich gar nicht erst anfangen. Wenn man mal 10 Monate auf bereits bezahlte Drucker gewartet hat, oder immer noch auf Druckplatten wartet, dann ist irgendwann einfach der Spass vorbei. Selbst auf als "Lagernd" gelistete Ersatzteile musste ich wochenlang warten, das kann ich mir bei Termindruck nicht leisten. So Sachen, wie vollmundig versprochene Features, die nie geliefert wurden darf man ja im Vergleich UltiMaker vs. Prusa nicht werten - da haben sich beide nicht mit Ruhm bekleckert. Der MK3 ist ein toller Basteldrucker für den Hobbybereich, aber im Semi Pro Einsatz nicht empfehlenswert, und absolut nicht wartungsfreundlich. Am UM2+ war jahrelang *nichts*, den UM3 hab ich noch nicht so lang, da war aber auch nie was bisher. An den Prusas ist ständig irgendwas. Wenn ich was dringend gedruckt haben will, gehts an einen der Ultis.

Kann mich Smithy nur anschliessen. Problem ist meist der Düsenabstand. Das kann zu weit weg sein oder zu nah dran. Darum auch die Frage nach einen Foto von der ersten Schicht. Und mach das Bett nicht zu heiss. Original Buildtak funktioniert zur Not auch ohne Bettheizung mit PLA, wenn der Abstand stimmt. 50°C sollte bei Buildtak reichen. Nimm ~210°C an der Düse für die erste Schicht, Lüfter aus für die erste Schicht und Speed erste Schicht <= 20mm/s. Und mach ein Foto.

Hast Du das Problem noch mit dem EcoPLA? Wenn ja, schreib mal welcher Drucker, machn Foto vom fehlgeschlagenen Druck, also von dem das was aufm Bett haften bleibt (oder auch nicht). Das Eco PLA sollte durchaus in Griff zu bekommen sein, ich hab da schon paar Rollen verdruckt von.

Zerspaner_Gerd hats oben schonmal vorgeschlagen, häng ihn mal per USB an den PC, Schieb den Kopf mal in die Mitte, und dann versuch mal, ob Du mit der Freeware Pronterface (pronterface.com) die Achsen steuern kannst. Ich bin gespannt auf X, ob die geht. Und wenn er dann schon mal da am USB hängt, guck mal ob er mit M119 den Status der EndStops anzeigt. Hab kein UM2, aber versuch wärs wert. Wenn ja, dann drückste und hälst den Endstop und machst nochmal M119.

Also bei mir hatte ich das Display "Hüpfen" am UM2+ schon vor dem Wechsel auf Tinker. 100% sicher, weil ich noch gedacht habe, ob das mit Tinker eventuell besser wird 😉

Hmm.. bugs have been fixed according to the changelog ( https://www.simplify3d.com/software/release-notes/ ), unfortunately not the ones I was having problems with. Since the change log only lists some of these bugfixes, who knows. Supposedly 100+ more fixes went in, which ones is anyone's guess. The 3-4 bugs / reproducible issues i've had are still in. The disappointment stems from the fact that the "main features" of this update, as announced here: https://www.simplify3d.com/software/release-notes/version-4-1-0/ are imho a bit of a let down. Support for 6 extruders, better rafts. Ok, but not sure if that's what the majority of the user base has been waiting for. More accurate print time estimates as the 2nd featured item? Besides the fact, that it'll still be off...I just can't get excited about. Problems: well, besides the new dynamic prime towers either not rendering properly or not working at all, and not having the first clue where to specify the dimensions of the extruder to actually use the new "collision detection in sequential printing" they added, no, no new problems so far. But then again, they didnt add much to begin with.. Who said 2 out of 3 aint bad? ? In short: too little too late. Looks to me they're unwilling or unable to maintain meaningful development. Cura and Slic3r already surpassed S3D in features, I am finding less and less reasons to tell my folks: it is still worth spending $150 on simplify3d. Heck, after using S3D exclusively since 2016, I am now catching myself using Cura 3.4.1 <g> more and more. Because, you know, it has some really useful features that S3D doesn't have and probably never will.

I installed it.. And honestly, I shouldn't have bothered. What a disappointment.

Thanks.. I guess these are somewhat ( <g> ) valid reasons. I don't necessarily agree with the decision by the profile team, I would have wished for "print quality" over "print speed" or "less support questions" being the primary focus. (Sorry if this sounds harsh, its not meant as such) To me "Recommended" Settings means - or should mean imho - that I can tell an inexperienced employee to to just hit print in "Recommend" and end up with a decent print without having to go to Cura University first to learn what all of the 500+ settings in Custom mode mean.. Hence, if 2 materials are used, we get a prime tower that is thick enough to not break (as mine just did with my first CPE & Breakaway print - trial and error with any new material & machine, no biggie). My recommended settings would lean to overdo it to make triple sure the print works well - and sell more filament ? Cura is getting a nightmare to train folks in - or to support them if questions arise, so I hoped for Recommended to be the easy way out. NFC reads the tag and recommended switches to "guaranteed" (as much as possible) working settings for this combination. While the experienced folks use Custom and disable the prime tower if they think they can get away with it. I shall have to create a bunch my own profiles then. Dratts, but I think I'll manage ?
