Kobra - gu waxa uu leeyahay bakhtiiye toos ah, kaas oo ah wax aan caadi ahayn oo ka dhex jira daabacayaasha goobtan qiimaha. Guud ahaan, madbacadaha fiilooyinka waxay leeyihiin mid toos ah oo kaxeeya ama baqaha qaansada. Bowden extruders riixaya fiilka galay sanka ka fog, oo lagu hago iyada oo loo marayo tube teflon ah, halka extruders drive toos ah ay ku rakiban yihiin midig ka sarreeya dhamaadka kulul, si weyn u yaraynaysaa caajiska gudaha tuubada sababtoo ah aad bay ugu dhowdahay sanbabada.

Kobra - ku waxa uu leeyahay dareemaha baadhista inductive ee cabbirka sariirta tooska ah. Waa dareemayaal u dhow oo ogaan kara biraha u dhow. Sax maaha sida BL Touch laakiin aad bay uga jaban tahay waxayna ku siin kartaa natiijooyin aad u fiican. Prusa waxay u isticmaashaa kuwan daabacayaasha laba jeer ka qaalisan, sida Prusa MK3 . 

Sariirta kuleylka leh waxay leedahay go' bir ah oo guga ah oo ku dheggan xagga sare ee birlabeedka sariirta, taasoo ka dhigaysa mid aad u fudud in laga saaro daabacaadaada.

Kobra - gu waxa uu yimaadaa qayb la ururiyey-sabab kale oo ay ikhtiyaar fiican u tahay bilowgayaasha daabacaadda 3D. Waxaad baran doontaa sida makaanikada daabacuhu u shaqeeyaan markaad isku dubaridayso, mana qaadan doonto waqti aad u dheer maadaama qaybo badan oo ka mid ah mar hore la isugu geeyay adiga.

Waxa ay nagu qaadatay ilaa shan iyo toban daqiiqo in aanu soo ururino Kobra^(Kobra) . Tilmaamuhu si cadaalad ah ayay u caddaayeen, in kasta oo sawirada buug-gacmeedka golaha ay ka badnaan karaan. Ma jiraan wax badan oo khalkhal gelin kara. Maareynta fiilada ayaa ah meesha aad rabto inaad ka taxadarto.

Matoorada stepper mar hore ayaa lagu rakibay. Waxay u baahnaayeen oo kaliya in lagu xidho iyadoo la isticmaalayo fiilooyinka la bixiyay. 

Calibration

Anycubic waxay ku talinaysaa in la hubiyo xiisada suunka iyo in la hubiyo in saxanka la dhisay iyo dhidibka x ayan gariirin. Uma baahnin in aan wax hagaajin ah ku samayno lowska eccentric ee xakameynaya sida ugu adag ee rollers-ku u qabsanayaan soo saarista aluminiumka. Uma baahnid inay aad u cidhiidhyaan, oo hubaal ma rabto inay aad u dabacsan yihiin. Haddii aad u baahan tahay inaad hagaajiso, way fududahay. Kaliya waxaad rogtaa lowska eccentric ilaa uu gariirku joogsado—oo aan cidhiidhi ahayn.

Haddii aad u baahan tahay inaad hagaajiso xiisadda suunka, waa toos. Suunka kasta waxa uu leeyahay biro birta ah. Laba qof ayaa rogrogay furayaashaas, waadna dhammaatay.

Ka dib markii aanu samaynay heerka sariirta tooska ah, waxaanu hagaajinay z offset-ka. Si taas loo sameeyo, waxaad gelisaa xaashida birta hoosteeda oo aad hagaajiso ka-goynta ilaa ay waligeed-wax-yar u qabato warqadda. Waxaad u baahan doontaa inaad si fiican u hagaajiso tan maadaama lakabka koowaad la daabacayo. Waxaan ku qasbanahay inaan kor u qaadno 0.1mm offset-ka. Natiijooyinkaagu way kala duwanaan doonaan.

Dhis tayada Kobra kasta oo cubic ah

Waxa kaliya ee aanaan jeclayn tayada dhismuhu waa in dhidibka z-axis uu leeyahay hal baal oo rasaas ah. Iyadoo taasi jirto, dhidibka x-ku wuxuu u muuqday mid deggan. Annagu ma aannu dareemin wax miyir-beel ah. 

Mareeyaha qaboojiyaha waa yara qaylo badan, laakiin waxay u badan tahay inaanan ogaan lahayn haddii daabacaaduhu aanu aad u aamusnayn. 

Fiilaha fiiluhu wuxuu taagan yahay xagga sare ee daabacaha. Waxaan doorbidi lahayn xagga hoose maadaama culeys kasta oo dheeri ah oo ku yaal xagga sare ee baabuurka tooska ah uu ka dhigi karo daabacaha rux. Dhanka kale, ma jiraan wax caddayn ah oo muujinaya in taasi dhacday intii lagu jiray daabacaaddayada.

Daabacaadda Koowaad

Daabacaaddii ugu horreysay ee tijaabadii, waxaanu isticmaalnay feylka tijaabada ee ku jira kaarka SD oo lagu daabacay Fillaha Anycubic PLA^{(Anycubic PLA)} . Iskuma dayin in aan ku daabacno fiilada ABS sababtoo ah, waayo-aragnimadayada, taasi waxay u baahan tahay xero-xidhid si aan rajo uga qabno helitaanka tayada aad ka filayso PLA .

Wax dhibaato ah nagama qabin ku dhegganaanta sariirta daabacaaddayadii kowaad. Daabacaadda qayb ahaan la sii daayay markii sariirtu qaboojisay, taas oo ahayd mid fiican.

Sida aad arki karto, waxaan helnay daabac wanaagsan isku daygii ugu horreeyay. Waxa jiray xadhig yar (runtii, ku dhawaad ​​midnaba). Ciladda kaliya ee weyn waxay ka dhalatay bac aan ku guul darreysannay inaan ka saarno birta. Waxaa si gaar ah noogu soo jiitay tayada daabacaadda dhegaha ee ku yaal xagga sare ee guumaysta-madbacadaha ayaa inta badan la halgama qaybo khafiif ah oo xagal sare ku yaal oo kala go'ay, una baahan in sanbadhku kor u qaado oo uu dhaqaaqo. 

Anycubic ayaa sheegay in xawaaraha daabacaadda Kobra uu 167% ka dheereeyo tartamayaasha. In kasta oo xawaaraha daabacadu aanu ahayn kii ugu dhaqsiyaha badnaa ee aan waligay aragno, haddana taas ayaan filaynay. Waa baayac-mushtar ah in la haysto duuliyaha tooska ah halkii uu ka ahaan lahaa bowden. Fikradeena, ka jawaab celinta duuliyaha tooska ah waa ganacsi la aqbali karo oo loogu talagalay xawaaraha daabacaadda waxoogaa gaabis ah.

Review of Anycubic’s Kobra 3D Printer

In yet another stop alоng our journey to find the best affоrdable entry-level 3D printerѕ, we had a chance to try out the Kobra 3D printer from Anycubic. The Kobra is a minimal-assembly kit that costs US $299.00 on Anycubic’s official website and on Ali Express. Or you can buy it on Amazon for $319.99.

In this 3D printer review, we’ll let you know what you get when you buy an Anycubic Kobra, what it’s like to build it, and our first impressions about its quality and usability. 

Features of the Kobra by Anycubic

The Kobra by Anycubic is an FDM 3D printer. FDM stands for fused deposition modeling. The print material for FDM printers is plastic filament. If you’re considering buying your first 3D printer, you could also consider a resin printer like the Anycubic Photon Mono X, the larger Photon Mono X 6K, or the Photon M3.

The Kobra’s features include: 

• Build volume of 9.8 x 8.7 x 8.7 in. (250 x 220 x 220 mm)
• Machine dimensions of 19.1 x 19.1 x 16.9 in. (486 x 486 x 430 mm)
• Uses 1.75mm PLA, ABS / PETG & TPU filaments
• Ø 0.4 mm replaceable nozzle
• A heated, textured, removable, and flexible build platform made of PEI spring steel
• Ports for USB and microSD card 
• 4.3″ color touchscreen LCD
• 25-point auto bed leveling with an inductive sensor using Anycubic’s LeviQ technology

The Kobra has a direct-drive extruder, which is relatively uncommon among printers at this price point. In general, filament printers have either a direct-drive extruder or a bowden extruder. Bowden extruders push the filament into the nozzle from a distance, guided through a teflon tube, whereas direct drive extruders are mounted right above the hot end, greatly reducing the slack inside the tube because it’s so much closer to the nozzle.

The Kobra has an inductive probing sensor for automatic bed leveling. It’s a proximity sensor that can detect nearby metals. It’s not quite as accurate as something like the BL Touch but it’s dramatically cheaper and can give you excellent results. Prusa uses these on printers that are twice as expensive, like the Prusa MK3. 

The heated bed has a spring steel sheet that attaches to a magnetic top on the bed, making it incredibly easy to remove your prints. Just remove the spring steel sheet and crack it like an ice tray. In our test print, the print even released itself from the bed as it cooled. Moreover, the bed leaves a nice texture on the underside of the print. 

The LCD touchscreen is quite similar to the screens on some of Anycubic’s other printers, like the Anycubic Vyper. It’s intuitive, responsive, and easy to read.

The print volume is quite similar to the Vyper’s, as well, and the print beds are identical. Lastly, the Kobra has optional filament run-out detection. You can turn that feature on or off via the touchscreen panel. 

Assembling the Anycubic Kobra 3D Printer

The Kobra comes partially assembled—another reason it’s a good option for beginners to 3D printing. You’ll learn how the printer’s mechanics work as you assemble it, and it won’t take very long since many of the parts are already put together for you.

It took us about fifteen minutes to assemble the Kobra. The instructions were fairly clear, although the photos in the assembly manual could have been larger. There’s not a whole lot to mess up. The cable management is where you want to be the most careful.

The stepper motors are already mounted. They just needed to be plugged in using the provided wiring. 

Calibration

Anycubic recommends checking the tension of the belts and ensuring the build plate and x-axis don’t wobble. We didn’t need to make any adjustments to the eccentric nuts which control how tightly the rollers grip on the aluminum extrusions. You don’t want them too tight, and you definitely don’t want them too loose. If you do need to adjust them, it’s fairly simple. You just turn the eccentric nut until the wobbling stops—and no tighter.

If you do need to adjust the belt tension, it’s straightforward. There’s a screw tensioner for each belt. A couple turns of those screws, and you’re done.

After performing the automatic bed-leveling, we calibrated the z offset. To do that, you put a piece of paper under the nozzle and adjust the offset until it ever-so-slightly grips the paper. You’ll need to fine-tune this as the first layer is being printed. We had to raise the z offset 0.1mm. Your results will vary.

Build Quality of the Anycubic Kobra

The only thing we didn’t like about the build quality is that the z-axis only has one lead screw. Despite that, the x-axis seemed pretty stable. We didn’t notice any sagging. 

The cooling fan is a bit noisy, but we probably wouldn’t have noticed if the printer weren’t so quiet. 

The filament spool is positioned at the top of the printer. We would have preferred it at the bottom since any extra weight at the top of the direct-drive extruder could make the printer shake. On the other hand, there was no evidence of that happening during our prints.

First Print

For our first test print, we used the test file included on the SD card and printed with Anycubic PLA filament. We didn’t try printing with ABS filament because, in our experience, that requires an enclosure to have any hope of getting the quality you expect from PLA.

We had no problems with bed adhesion on our first print. The print partially released when the bed cooled, which was nice.

As you can see, we got a good print on our first attempt. There was minimal stringing (really, almost none at all). The only large defect was caused by a piece of plastic we failed to remove from the nozzle. We were particularly impressed by the print quality of the ears at the top of the owl—printers often struggle with thin parts that are at a steep angle and are separated, requiring the nozzle to lift and move. 

Anycubic says the Kobra’s printing speed is 167% faster than competitors. While the print speed isn’t the fastest we’ve ever seen, we expected that. It’s a trade-off for having a direct-drive extruder instead of a bowden. In our opinion, the responsiveness of a direct-drive extruder is an acceptable tradeoff for the slightly slower print speeds.

Cut to the Chase

Virtually every entry-level 3D printer gets compared to the Ender 3. In this case, the Kobra out-performs the Ender 3 in these areas:

• Less stringing because of the direct-drive extruder
• Comes with a magnetic bed for easy print removal
• No x-axis sagging
• Vastly superior touchscreen

With the Kobra, you’ll get high-quality prints for under $300. If you’re interested in a similar printer with a much larger build volume, keep an eye out for our upcoming review of the Anycubic Kobra Max, a monster FDM 3D printer we simply loved.
