  • Will it come with filament?

    It comes with 200g PLA filament.
  • Why the filament can't stick on the heat bed?

    1. Paste high temperature adhesive tape on the heat bed or using 3D print heat bed glue.

    2. The distance between the nozzle to heat bed is very important, please keep the distance is about 0.2 - 0.3mm.

    3. Some types of filament need higher temperature of heat bed, usually PLA is 50 - 60 degree, HIPS/ABS/PC is about 80 - 105 degree.

  • Extruder cannot heat up to setting temperature, what can i do?

    1. Check the blowing fan is on off or not when extruding, if on please turn off it first.

    2. Check whether the heater wire connected well or not.

    3. Disconnect the heater from the control board. test two ends of heater by a multimeter(using resistance grade), if resistance is over 10 OHM, it means the heater is broken.

  • How to update the firmware?

    The firmware upgrade for this machine is very convenient, if the machine's firmware has a major change that needs to be updated, the manufacturer will provide two files to the user, Users only need to copy these two files to the SD card, and then restart the machine. After the machine progress bar is completed, the firmware is refreshed. Then the user needs to delete the two files in the SD card before the machine is used normally. Otherwise, the firmware will be refreshed each time when started the machine.
  • How do I know the links to update the firmware? If SD card data is lost, how can we find it?

    Bu fiyata En Kaliteli 3D Yazıcı CREALITY CR-10 Katili resmen :)
    Color:Black Size:EU Plug
    İlk yazıcım JGAurora A5 Modeldi. Ve o modelide deneme amaçlı almıştım. Sonrasında dedim biraz daha uygun modelleride deneyeyim. yaklaşık 1000tl daha ucuz bir yazıcı buldum ve karşıma AŞFAVISE U20 denk geldi. İlk başlarda tereddütlüydüm fakat yazıcı geldiğinde ve ilk baskıyı yazdırdığımda zaten şok oldum.
    1 ay sonra Alfawise U10 modelinide satın alacağım.:) Daha ne diyim yani.:) Detaylı baskısı videoda mevcut. Videomu youtube dan açıp izlerseniz görebilirsiniz. Ve almak isteyen olursa video altındaki bağlantı üzerinden alırsa çok sevinirim.

    Kademe kademe anlatmak gerekirse:
    1- Kaliteli metal profile sahip ve hiç titreşim yapmıyor. (En çok korktuğum noktaydı )
    2- Montajı kolaydı (Kablolama kısmında biraz karşık gelebilir ama aslında bilen için çok basit. Fakat yeni alanlar yarım saat uğraşabilir :)
    3- Isıtmalı tabla olması çok iyi hatta diğer şık hemen altta :)
    4- Isıtmalı tablanın cam değişimi dahada iyi. Diğer yazıcılarda malesef cam ile ısıtma yüzeyi yapışık oluyor ve bu sebeple değişimi çok sıkıntılı ama bunda öyle değil.
    5- Cam tabla yüzeyi gerçekten çok iyidi. Kalitesiz dursada baskı alınca filamentin yapıştığını görünce sizinde fikriniz değişebilir. :)
    6- Filament sensörü olması da gerçekten büyük artı. Çünkü bundan pahalı olan creality markasında o yok şahsen.
    7- Filament bittiğinde veya değiştirmek gerektiğinde baskı kaldığı yerden devam edebiliyor. Creality cr-10 modelinde o özelli YOK :)
    8- Extruder küçük görünse bile işini çok iyi yapıyor.
    9- Nozzle Isınma süresi gayet hızlı 20-30 saniye gibi kısa bir sürede nozzle baskıya hazır ısıda oluyor. Tabla daha geç ısınıyor.
    10- Z Ekseni yüksekliğinin 40cm olması zaten bu fiyata muazzam ötesi. Bundan daha pahalıya satılan creality de 30cm malesef. Güncellenmiş versiyonu bununla aynı ölçüde fakat oda bundan 1000 tl daha pahalı.
    11- Yüksek çözünürlüklü baskı alabilmeside çok iyi. İlk baskı 0.2mm ile denedim ikinci baykuş baskısını 0.1mm de bastı ve muazzam ötesi kaliteli ve hızlıydı.
    12- Güncelleme ile 0.05mm çözünürlüğe kadar baskıya müsaade ediyor. Hatta eğer uğraşırsanız daha altında bile baskı verebilir.
    13- Dokunmatik kontrol paneli işte en büyük artısı. Kolay kullanım arayüzü ve sorunsuz ayarlama imkanı sağlıyor. Creality de dokunmatik özelliğide yok :)
    14- Tabla ayarı çok rahat ve kolaydı. Dokunmatik ekranda gerekli leveling ayarını yapabiliyorsunuz ve tablanın altına eliniz rahatça girebiliyor.
    15- tek Z Ekseni motoru olmasına bakmayın. Bende ilk baş çok şüphe ettim çünki JGaurora da dual z eksen motoru mevcuttu ve memnundum. Ama bunda hiç bir sıkıntı yok. O konudada beni çok şaşırttı.
    16- Nozzle ve Filament soğutmasıda cidden JGaurora dakinden daha iyiydi.
    17- Z Eksen milini tavan kısmına sabitlemeleri zaten baskı kali
    Suggestion
    Aslında çok aşırı eksiği yok. Ki bunlar bu fiyata eksi çzellik olarak değerlendirilmez. Fakat yinede yazalım.

    1- Dual Z step motoru olursa çok daha iyi olur.
    2- Kablo karmaşasısnı biraz daha düzenlemeleri gerekli.
    3- Kabloları biraz daha uzun yapmış olsalar daha iyi olurdu. Ki kullanıcılarında kablo düzeni yapması kolay olabilirdi.
    4- Fiyatı biraz daha arttırıp BL-TOUCH sensörü eklerlerse eğer mükemmel olur. Çünkü artık her yazıcıda Auto level yani Otomatik tabla ayarı olması gerekli diye düşünüyorum.

    Fakat dediğim gibi bu fiyata Creality cr-10 KATİLİ :) Creality bildiğiniz çöp arkadaşlar. Çok satıldı diye havalandılar ve fiyatları çok aşırı pahalandı. İlk başlarda ucuzdu ama şuan hiç değmez.

    très belle imprimante avec une magnifique conception mécanique, la partie contrôle et pilotage est elle à améliorer
    Color:Black Size:EU Plug
    Mon test en français : http://bit.ly/2MNGOGR
    Good points
    + the value for money of this 3D printer is very correct: 260 € for such a great printer, it's great
    + the capacity (size of the work area) is great: 300 * 300 * 400 mm it's very big
    + It is almost completely assembled, the rest of the assembly is easy to do and fast
    + it has an excellent ratio global footprint / size of the work area
    + the structure in aluminum profiles is perfectly rigid
    + beautiful prints with the current filaments
    + the heating plate is extremely powerful: it is monobloc (the resistance is crimped on the aluminum plate): high efficiency, the heating is fast (less than 5 minutes for 70 ° C)
    + over-glass does not reduce much heating time and keeps the surface very flat
    + much more successful than my other printer "Anet E10", which had a lot of small defects (small savings that make a big difference)
    + numerous accessories (PLA wire, stainless steel spatula: to sharpen, needle of unblockings, keys of adjustment and assembly, cutting pliers PRO ...)
    + LCD color touch screen
    + a dedicated Facebook page for help and updates

    She also has negative points
    - the external fans are of average quality (noisy for my taste)
    - the internal software is not yet completed: bugs, lack of options and NO compatibility with Repetier-host or recent versions of Cura.
    - the heating plate coating is good but not sufficient for hard to adhere materials such as ABS or HIPS
    - the provided spool support is really too small

    alfawise u20. it's worth your money.
    Color:Black Size:US Plug
    I started off with a small printer, to learn how these work before going for larger print volumes.. the u 20 IS THE LARGER PRINT VOLUME. it was easy to assemble, had it together in about 20 minutes. the packaging was great, everything was secured in the box well. I joined the facebook group alfawise u20 and I believe everyone purchasing this printer should, as updates are offered for download to keep your system updated when new things are added... I've had no negative issues with the printer, the heated bed works well and warms quickly.

    I had my first storm power outage and the power resume worked as intended. it simply warmed up the hot end, homed the x and y and continued printing.. that's awesome..

    I would print a spool holder for it as the one provided has trouble with full sized spools of plastic. it works well for the provided spool though..

    I cannot wait to really get some hours under this printers belt and watch the great things it prints for me... I love movie props and statues, so this bed size is going to be fully taken advantage of...

    this is a great printer and the price is nice. join the facebook group, take advantage of the updates and learn from the other nembers, maybe I'll see you there..

    A gift for my son's admission to his favorite university
    Color:Black Size:US Plug
    My son had asked me to buy an open-frame FDM 3D printer for him, because he loves 3D printing lessons and feels proud of his 3D-printed models. They are something extraordinary. After the admission, I though it might help with his major in the university. Now that my son is interested in 3D printing, he can keep himself occupied before the beginning of the new semester and studied a lot of knowledge. After several long hours prints (about 2 - 3 days), he gave a positive review and put it online.
    According to him, the nozzle will not be clogged and the printing quality is great when the extruder is working at a high speed. Indeed, the details of the models he made are fascinating. What he likes the most is the combination of printing directly from Micro SD card, filament run-out protection and power cutoff protection. Because 3D printing takes much longer time, these three features help to avoid any possible imperfection and restart.
    He thought the problems are not a big deal and many can be easily fixed. For example, he replaced the cooling fan, and ignored the scratches on the gantry caused during the shipment.

    The 3D printer is competitive and promising
    Color:Black Size:EU Plug
    Pros:
    I love the increased use of metal brackets. The belts are also pre-tightened perfectly. I have few complaints about any part of the actual physical construction of the printer. It is nice.
    Besides the noise and salmon skin, the print quality looks very promising. Layers are aligned very well, making watertight. Print is surprisingly easy. I'm very pleased with the potential of this printer. It has the potential of actually being real competition to a CR10 with just a few tweaks and upgrades.
    I like the touchscreen so much that I want to use it on my other 3D printers. The user interface is absolutely fantastic. One of the best I've ever touched.
    Both the glass plate and the aluminum plate for the heat bed are both incredibly flat, so I can print directly on it. Whereas, it is not the case with Creality CR10.
    Cons:
    One has to stand up in order to look at the screen because it is not angled or tilted horizontally;
    The bolts are loose from the factory I had to retighten many of them;
    The cooling fan is too noisy. It is better to be replaced by one with a higher quality.

    Competitive Large Build Volume 3D Printer
    Color:Black Size:US Plug
    I waited 2 days to get my first print which takes up the full size of 30 x 30 x 40cm. It is incredibly perfect. Certainly, there exist some noise which is unavoidable for FDM printers. The better the filament you use, the higher printing quality will be. It takes me only 6 minutes to finish connecting the frames and the cables, although I did not have a look at the instruction. This is because there are labels at the end of the cable, so what you need to do is only to match them. It is easy and time-saving! I also like inserting a TF card to print, so I do not need to keep the computer operating for tens of hours.
    As to its disadvantages, the 3D printer had not been packed well, although everything inside is intact. Different parts needed to be separate apart. Evidently, this is something that you should think highly of.

    Great Printer. Only requires a little technical knowledge and tweaking
    Color:Black Size:US Plug
    Up till now, I'm loving this 3D printer. It shipped quickly and everything arrived well packed. I really wanted to print some buildings to finalize the design.
    Unpacking, assembly and leveling took me about half an hour. It was easy, I just followed the user manual step by step though it is not detailed at all.
    The first thing I tried to print was the included test file on the SD card, then, I set about printing my own. I did get some failures, at least 2 prints failed within 2 weeks, because the cooling fan ended up broken and dragged plastics across my prints. I printed a new one after disabling the cooling in Cura and prints have been going solid from then on.
    Hairspray seems to work the best for me to make the print stuck on the bed in comparison, the tape and glue haven't worked well.

    Love it! This is my first 3D printer
    Color:Black Size:US Plug
    Easy to assemble!
    Easy to use!
    Quality printing!
    I had been expecting the arrival of Alfawise U20 after I had ordered it. It took me about 10 minutes to put the three parts together and finish leveling. Really fast! Another good thing is that the glass plate is flat, so I did not need to replace it. After testing several small prints and full-size prints, I concluded that the printing precision is great, and the salmon skin that the printer produces is exquisite. The layers are perfectly aligned even it is operating at 150mm/s. This is incredible!
    A little paint came off from the metal frame. The package needs to be improved; the spool holder does not support 1kg filament, which is a pity. However, the problems are minor.
