Mid ka mid ah waxyaabaha ugu horreeya ee aad rabto inaad ku samayso daabacaha cusub ee 3D waa inaad barato sida loo beddelo fiilada. Hagahan tillaabo-tallaabo ah wuxuu ku barayaa sidaad isku beddesho fiilooyinka fiilooyinka iyada oo aan waxyeello loo geysan ama aan la xirin sanka-saariyaha.

Tilmaamahani waxay u shaqayn doonaan inta badan daabacayaasha FDM -laga bilaabo ^(FDM)Creality Ender 3 ilaa Voxelab Aquila S2 ilaa Anycubic Kobra . Taasi waxay tidhi, had iyo jeer way fiican tahay inaad akhrido buug-gacmeedka daabacaada 3D, gaar ahaan haddii aad ku cusub tahay daabacaadda 3D ama aad isticmaalayso nooc aanad waligaa isticmaalin.

Sida Loo Bedelo Filament -ka Daabacahaaga 3D

Waxaa jira dhowr sababood oo caadi ah oo lagu beddelo fiilooyinka.

• Waxaad gaadhay dhamaadka fiilada ku dul socota dababka.
• Waxaad rabtaa inaad isticmaasho nooc ka duwan fiilo.
• Waxaad rabtaa inaad beddesho fiilaha daabacaadda dhexe si aad u gaarto saameyn.
• Fiilaha hadda jira waa dhaawac.

Sabab kasta ha ahaatee sababta aad u rabto inaad u beddesho fiilooyinka, tillaabooyinka asal ahaan waa isku mid.

1. Kordhi Printerkaaga

Hubi^(Make) in daabacahaagu uu shido. Neefku waa inuu kululaadaa si uu u bedelo fiilada. Haddii aysan taasi ahayn, waxaa laga yaabaa inaadan awoodin inaad nadiifiso fiilkii hore, oo ma awoodi doontid inaad ku shubto fiilada cusub ilaa cidhifka birta.

2. Deji heerkulka la rabo^{(Desired Temperature)} ee dhamaadka kulul^(Hot)

Waxaad u baahan tahay inaad ogaato heerkulka lagu taliyey ee daabacaadda ee fiilooyinka hore loogu shubay daabacaha (haddii ay jiraan) iyo heerkulka lagu taliyey ee filaha aad rabto inaad ku shubto. Ku sii kululee dhamaadka kulul ilaa sare ee labadaas heerkul. Tani waxay ka hortagi doontaa dhibaatooyinka extrusion hadhow.

Waa kan sababta. Inta aad ku shubayso fiilada cusub, waxaa jiri kara laba nooc oo fiilooyin kala duwan isku mar isku mar ah-wax yar oo fiilaha hore ah iyo sidoo kale filaha cusub ee aad ku shubayso. Heerkulka biibiile wuxuu u baahan yahay inuu ahaado mid sare oo ku filan inuu dhalaaliyo labada nooc. Haddii kale, waxaa laga yaabaa inaad la soo baxdo caarad xiran.

Tusaale ahaan, qiyaas inaad ku daabacanayso PETG , oo aad rabto inaad u beddesho filament PLA . Sababtoo ah PETG waxay ku dhalaalisaa heerkul sare, haddii aad u dejin lahayd heerkulka PLA , PETG waxaa laga yaabaa inaanay si buuxda u dhalaali oo aan si buuxda loo nadiifin inta lagu jiro isbeddelka fiilada. Tani waa qaladka ugu badan ee ay dadku sameeyaan marka ay beddelaan fiilooyinka.

3. Ka saar Filalkii hore

Qaar ka mid ah daabacayaasha ayaa lahaan doona ikhtiyaarka menu ee shaashadda LCD-ga^(LCD) daabacaha si ay u dejiyaan fiilaha jira. Madbacadaha kale, tani waxay noqon kartaa hab dhammaystiran oo gacanta ah. Tixraac dukumentiyada daabacahaaga. Haddii ay tahay mid toos ah, isticmaal doorashadaas oo raac tilmaamaha shaashadda.

Markaad gacanta ka saartid fiilkii hore, haddii sanbadhku aad ugu dhow yahay sariirta daabacaha si aad u hesho farahaaga hoostiisa, hel amarka dhidibka dhaqaaqa^(Move) daabacaha oo kor u qaad dhidibka z-axiska ilaa 50mm.

Marka xigta, dami matoorada stepper-ka. Taasi badanaa waxay ku jirtaa goobaha xakamaynta. Haddii kale, waxaad diri kartaa amarka g-code, m18.

Qaar ka mid ah daabacayaasha tuubada Bowden , sida ^(Bowden)Ender 3 Pro , waxay leeyihiin kabaal gacan-ku-saar ah si ay u sii daayaan fiilada mashiinka jaranjarada. Si tartiib ah u jiid fiilada ilaa ay gebi ahaanba ka go'do daabacaha. Ka taxadar inaadan si adag u jiidin. Waxaa laga yaabaa inaad jebiso fiilada.

Haddii ay jiraan wax badan oo iska caabin ah, laba jeer hubi heerkulka dhamaadka kulul; Hubi in matoorada stepper-ku ay maqan yihiin, iyo, haddii aad leedahay bakhtiiye Bowden , hubi in aad isticmaalayso kabaalka extruder-ka gacanta haddii loo baahdo.

Ka dib markaad ka saarto fiilada, ka fiirso inaad xoogaa hawo cadaadis ah ku afuufo qalabka wax saaraya si aad uga saarto wixii balaastig ah ee laga yaabo inuu ururay.

4. Diyaari^(Prepare) oo Raro ^(Load)Galka^{(New Filament)} Cusub

Kormeer fiilada cusub Hubi^(Make) inaysan jirin wax qaloocsan, meelo daciif ah, ama meelo go'an. Waxaad doonaysaa in fiilku u ekaado oo uu dareemo mid daahir ah. Cidhifyada faraha ayaa aad xasaasi u ah, markaa ku orod farahaaga dhawr cagood oo fiilada ah si aad u aragto haddii aad dareemi karto wax cillado ah. Haddii aad sameyso, jar qaybtaas fiilada oo iska tuur.

Inta aad kormeerayso fiilada, iska hubi in aanu ka furmin spool-ka. Ma rabtid in fiilku is dhaafiyo ama la qalloobo.

Si aad u diyaarisid fiilada cusub, isticmaal fiilada siliga ama mandiil si aad u gooyso fiilada xagal 45-degree ah. Waa in ay caarada ka dareentaa fiiqan. Tani waxay hubinaysaa in ay si fudud u dhex galeyso daabacaha. Ku dheji fiilada fiiladu ka hor intaadan sii wadin.

Haddii daabacaadhaagu leeyahay ikhtiyaarka menu-ka ee lagu soo rari karo fiilada, hel, oo raac tilmaamaha shaashadda. Haddii aysan taasi dhicin oo uu yahay daabacaha Bowden , iska hubi inaad isticmaashid siideynta gacanta marka aad ku dunto filaha cusub ee tuubada Bowden .

Haddii daabacahaagu leeyahay fiilo-sheegaha dareeraha ah, hubi inaad ku shubto fiilaha. Ku riix fiilada ilaa inta nadiifintu dhammaato, oo aad aragto fiilo dhalaalaysa oo ka soo baxaysa tuubada. Xaqiiji^(Confirm) in midabku uu la mid yahay midabka fiilaha cusub ee aad ku shubayso.

Kadib markaad beddesho fiilaha, hubi in heerkulkaaga dhamaadka kulul uu u dhigmayo heerkulka lagu taliyey ee filka cusub ee la raray. Haddii aad gacanta ku soo dejiso, mar haddii ay ku dhufato heerkulbeegga bartilmaameedka, ku riix fiil yar oo dheeraad ah. Haddii heerkulka dhamaadka kulaylku laga dhigo mid ka sarreeya fiilada aad ku shubayso, waxaad u baahan doontaa inaad si dhakhso ah u shubto fiilada cusub oo aad isla markiiba hagaajiso heerkulka dhamaadka kuleylka si uusan fiilku aad u kululaan.

Ka saar fiil kasta oo la soo saaray. Hubi^(Make) in sanbadhku nadiif yahay oo diyaar u yahay inuu tago.

Maxaad Samayn Kartaa Haddi Aad Ka Dhamaato Galka ^(Filament)Dhexda^(Middle) Madbacada

Haddii aad leedahay qalabka wax baadha ee fiilaha kaa baxay, daabacahaagu waxa uu ku baraarujin doonaa in fiilaha kaa dhammaaday. Raac tillaabooyinka kor ku xusan si aad uga saarto fiilaha hore oo aad ku shubto fiilaha cusub.

Guud ahaan, waxaad rabtaa inaad ku shubto fiilo cusub ka hor inta aanu fiilada jirta gebi ahaanba dhammaan. Haddii fiiluhu aad u gaaban yahay oo uu dhaafo qalabka wax-soo-saarka, waxaa laga yaabaa inaad kala soocdo-dhamaadkaga kulul si aad uga baxdo. Dareemaha dareeraha fiilaha oo dhamaa waa qasab, fikradayada. Haddii daabacahaagu aanu mid lahayn, tixgeli inaad mid ku darto.

Haddii aad ku beddesho fiilada isku nooc ah, waxaad ka tagi kartaa heerkulka dhamaadka kulul sida uu yahay. Haddii kale^(Otherwise) , raac tilmaamaha kore.

Haddii daabacahaagu aanu lahayn ikhtiyaarka menu dejinta si uu u beddelo fiilada, waxaad u diri kartaa m600 g-koodka daabacaha. Taasi waxay hakin doontaa daabacaadda oo ka dhaqaajin doonta madaxa daabacaadda si aanay u taaban daabacaada. Hadda waxaad ku shuban kartaa fiilada cusub sida kor lagu sharaxay. U dir m602 g-koodka si aad dib ugu bilowdo daabacaadda.

How to Change Your 3D Printer Filament

One of the first things you’ll want to do with a new 3D printer is learn how to change the filament. This step-by-stеp guide teaches you how to swаp filament spools wіthout damaging or clogging the extruder nozzle.

These instructions will work for most FDM printers—from the Creality Ender 3 to the Voxelab Aquila S2 to the Anycubic Kobra. That said, it’s always good to read the manual for your 3D printer, especially if you’re new to 3D printing or you’re using a model you’ve never used before.

How to Change the Filament on Your 3D Printer

There are several common reasons to change filaments.

• You’ve reached the end of the filament on the spool.
• You want to use a different type of filament.
• You want to change the filament mid-print to achieve an effect.
• The current filament is damaged.

Whatever the reason you want to change filaments, the steps are essentially the same.

1. Power Up Your Printer

Make sure your printer is on. The nozzle has to be hot to change the filament. If it’s not, you might not be able to purge the old filament, and you’ll be unable to load the new filament all the way to the tip of the nozzle.

2. Set the Desired Temperature of the Hot End

You need to know the recommended printing temperature range for the filament already loaded into the printer (if any) and the recommended temperature for the filament you want to load. Preheat the hot end to the higher of those two temperatures. This will prevent extrusion problems later.

Here’s why. While you’re loading the new filament, there may be two different types of filament in the nozzle at the same time—a little bit of the old filament as well as the new filament you’re loading. The nozzle temperature needs to be high enough to melt both types. Otherwise, you might wind up with a clogged nozzle.

For example, imagine you are printing with PETG, and you want to switch to PLA filament. Because PETG melts at a higher temperature, if you were to set the temperature for PLA, the PETG might not fully melt and may not be fully purged during the filament change. This is the most common mistake people make when changing filaments.

3. Remove the Old Filament

Some printers will have a menu option on the printer’s LCD screen to unload the existing filament. On other printers, this might be a completely manual process. Refer to your printer’s documentation. If it’s automatic, use that option and follow the on-screen instructions.

When manually removing the old filament, if the nozzle is too close to the printer bed for you to get your fingers under it, find your printer’s Move axis command and raise the z-axis about 50mm.

Next, disable the stepper motors. That’s usually in the control settings. Alternatively, you can send a g-code command, m18.

Some Bowden tube printers, like the Ender 3 Pro, have a manual extruder lever to release the filament from the stepper motor. Very gently pull the filament until it’s completely separated from the printer. Be careful not to pull too hard. You might break the filament.

If there’s a lot of resistance, double-check the hot end temperature; make sure the stepper motors are off, and, if you have a Bowden extruder, ensure that you’re using the manual extruder lever if necessary.

After you’ve removed the filament, consider blowing some compressed air into the extruder gear to remove any plastic flakes that might have accumulated.

4. Prepare and Load the New Filament

Inspect the new filament. Make sure there aren’t any bends, weak spots, or gouged areas. You want the filament to look and feel pristine. Fingertips are very sensitive, so run your fingers along a few feet of the filament to see if you can feel any flaws. If you do, cut that part of the filament off and discard it.

While you’re inspecting the filament, make sure it doesn’t unwind from the spool. You don’t want the filament to get crossed or tangled.

To prepare the new filament, use a wire snip or razor blade to cut the filament at a 45-degree angle. It should feel sharp at the tip. This ensures that it easily slides into the printer. Put the filament spool on the spool holder before you continue.

If your printer has a menu option for loading filament, find it, and follow the on-screen instructions. If it does not and is a Bowden printer, make sure you use the manual release as you thread the new filament through the Bowden tube.

If your printer has a filament runout detector, make sure you load filament through it. Push the filament through until purging is complete, and you see melted filament coming out of the nozzle. Confirm that the color matches the color of the new filament you’re loading.

After you’ve changed the filament, make sure your hot end temperature is set to the recommended temperature for your newly-loaded filament. If you loaded it manually, once it has hit the target temperature, push a little more filament through. If the hot end temperature is set higher than the filament you’re loading, you’ll want to load the new filament quickly and adjust the hot end temperature right away so the filament doesn’t get too hot.

Remove any filament that has been extruded. Make sure the nozzle is clean and ready to go.

What to Do If You Run Out of Filament in the Middle of a Print

If you have a filament run-out detector, your printer will alert you that you’ve run out of filament. Follow the steps above for removing the old filament and loading the new filament.

In general, you want to load a new spool of filament before the existing filament completely runs out. If the filament is so short that it moves past the extruder gear, you might have to take your hot-end apart to get it out. A filament run-out sensor is a must-have, in our opinion. If your printer doesn’t have one, consider adding one.

If replacing the filament with the same type, you can leave the hot end temperature as-is. Otherwise, follow the instructions above.

If your printer doesn’t have a settings menu option to change filament, you can send an m600 g-code to the printer. That will pause the print and move the print head out of the way so it’s not touching your print. Now you can load the new filament as described above. Send the m602 g-code to resume the print.
