    Super 3D-Drucker - Alfawise U20 ONE
    Vorab, das ist mein erster 3-D-Drucker. Er kam gut verpackt an und tatsächlich waren nicht allzu viele Schritte notwendig, um ihn aufzubauen.
    Die Anleitung ist für den Aufbau etwas dürftig. Daher empfiehlt es sich paar Youtube-Videos anzuschauen. Unter dem Verkaufsangebot ist auch ein Video, wo eine junge Dame den Aufbau tätigt. Das ist schon mal viel wert. Es ist schon eine Weile her, dass ich den Drucker aufgebaut habe. Mir ist aber so, dass ich mich bei den Kabelanschlüssen auf die Umsetzung der Anschlussstellengröße sowie der Kabellänge orientieren musste. Die benannten Beschriftungen an den Kabeln selbst brachten mir nicht wirklich viel. Mitgeliefert wird etwas weißes Filament zum Probe-Druck. Die mitgelieferte Matte ist auf die Glasplatte zu kleben. Das steht leider auch nirgendwo. Auch das erschließt sich aufgrund der mitgelieferten vier Klammern. Fälschlicherweise habe ich sie direkt auf die Heizplatte geklebt. Nun habe ich es so kalibriert und benutze es ohne Glasplatte. Auf einem Video war es (leider) genauso gehandhabt. So habe ich mich auch dazu verleiten lassen.

    Der Drucker tut, was er tun soll. Es stehen zwei Druckformate zur Verfügung, um sie über die mitgelieferte Mikro-Karte ohne Anbindung zum PC zu drucken. Ich schätze, die Lösung ist besonders für die Leute interessant, die den Drucker weiter weg vom PC betreiben möchten. Schließlich ist der Lärmpegel zwar erträglich aber doch störend. Eine direkte USB-Anbindung ist aber auch möglich. Die mitgelieferte Mikro-SD Karte steckt in einem USB-Adapter, um neue 3D-Druck-Dateien raufkopieren zu können. Dieser enthält auch 2 Beispiel-3D-Drucke , die Anleitung in EDV-Form sowie mögliche Programme zum Modellieren eigener Drucke (Ultimaker Cura usw.). Die Mikro-SD-Karte lässt sich schwer aus dem mitgelieferten USB-Adapter herausziehen. Es empfiehlt sich einen anderen Adapter zu benutzen. Ich lasse die Heizplatte auf 60 Grad und die Drucker-Drüse auf 200 Grad Celsius erwärmen. Das hat immer funktioniert. Größere Drucke habe ich noch keine anfertigen lassen. Das kommt vielleicht noch... ;-)

    Für Einsteiger wie mich kann ich diesen 3D-Drucker ruhigen Herzens weiterempfehlen. Es gibt tolle Videos bei YouTube auch in Deutsch dazu.

    Freie 3D-Drucke gibt es im Internet viele. Man kann diese mit der mitgelieferten Anwendung Cura für den eigenen Drucker formatpassend importieren und abspeichern.

    Good 3D printer .... BUT the service GNMPF
    After the indicated time of the U20 came one with me and was assembled relatively quickly. Then the trouble started. Unfortunately, neither a calibration and thus any pressure was possible. The support reigned as expected quite tough and even by e mail and Allerwelts advice. After 2 days, nightly search and ner pretty lousy mood I had found what it was, the micro limit switch of the Z axis was broken, probably 0.2 cents metal plate was simply not there. All attempts since failed to improvise something. The support further ruled tough and after I was in a bad mood significantly and this also communicated was answered "contact with the management" or threatened, I had as I should interpret it no idea what brought me really laugh. There were long photos and a video are made and the "SUPPORT" was still not sure what it was. It was so clear that it understood even people with very little technical understanding and interest. Simply Catastrophic this contact to the "SUPPORT". The offer was the printer to send to the camp to Spain (pointing to my cost) and then to be able to soon arrived choose among three options: Add Printer voucher Gearbest or your money back. I decided to laugh at you to order 4 Micro switch incl. Cable for € 13 and some change on EBay and take the whole into their own hands. Why 4, there were only a set. Support I laughed on to say it informed him that "Treebeard" Lord of the Rings is faster and waited for the switch. Once they were there, I soldered the micro switch (the board was 90 °) soldered it to the printer board and what can I say, it worked. The support has replaced me the amount of the switch. Print quality, I am now satisfied after many attempts but that more was up to me, a 96-hour endurance test he has passed well behind and genuine. All in all, it runs now but as I said, the support ??? Probably sitting somewhere in the world someone Allerweltsfragen can answer, but of technology, he really had NO idea. Too bad. If I order again at Gerbest? Yes, but I know that I'm asked me.

    Recommended but .....
    I chose this printer (my first printer) especially for the renewed style and the improvements made to the Z axis compared to the sister U20, here in fact we have a double motor on the Z axis and for the few tests I have done so far I can say that of the usual problems read around the forums, not even the shadow here. Everything arrived in an impeccable packaging, the inside of the box is preformed and there was no possibility for the various components to move during transport. Once the printer was assembled, I realized that many of the adjustments and tightening (even of the parts assembled from the house), needed a revised one. The plate was practically very slow on its track, as were the straps of the various axes. The cables run inside the corrugated cut on one side and especially those for the Z axis suffer a lot when printing at the maximum height, that is 400mm. I tightened everything and switched to the ignition and setup to find the right leveling of the floor. Here I immediately realized that something is wrong with the Y axis, it is as if the head (and therefore the extruder) could not reach a maximum stroke of 300mm ... actually I am still studying the question why in manual I can move freely around the entire plate, while in leveling or printing this thing is more than evident. However, I strongly recommend this printer, solid and easy to assemble, I am sure that once I find the solution to my problem (a matter of days), it will know how to satisfy all my needs. Brava Alfawise you made the center again this time ;-)

    Excellent printer el prices, but ...
    The alfawise U20 is an excellent printer for the price. Assembly as simple as possible, great and high printing surface, double motorization of the Z axis, color touch screen. The printing is good quality input, even if we can have the appearance of salmon skin, it is really great for the price. The fans are pretty quiet (relatively), the stepper motors, however, are a bit more noisy than on some printers. Small least are especially at the pre-assembly, even if the printer only happens in two parts and its assembly is simplified to the maximum, it is really necessary to check all screw tightening. I got for the model has been damaged threads at the "nuts" of the Z axis, which implies a new thread. Once these issues resolved, everything goes really for the best. Some improvements could beings useful buildtak of the bed hangs a little too much, even completely cold, sometimes it's really hard to shift parts and the user menu is not very intuitive. For my part, I added TL Smoothers, reinforcements for the Z axis you can find easily on Gearbest and I also changed the wheels on wheels polycarbonate less fragile than the original. Otherwise, go ahead, for the price, it really is happiness!

    Alfawise u20 one
    I chose this printer because it had good reviews and I must say that the five-star deserves all, just arrived (early) I immediately mounted, about an hour, the plate was detached from the base so after it mounted and tight springs almost full I did two times the calibration because of too much space between the nozzle and the glass in the first leveling, I find it very good and I would recommend it if someone asked 3d which printer to take, value great price, of course comes with the bare minimum but a once mounted every man can set up as required with the colors that own terms. I'm happy, a little something to uppare for perfection but for a neophyte who could go so well. I think further, not now ride on the smoother, the effect is there but salmon is not very pronounced and does not even make all this noise in the press. I think it's been updated in the first laps components, I saw video of shoddy pieces but this does not seem to have these problems. It has the glass plate which in some reviews is missing. Overall 5 stars.
