Yuav ua li cas los hloov cov neeg tsim khoom xaiv ntxiv rau lub rhaub dej kub

Yuav Hloov Cov Cuab Yeej Cuab Yeej Li Cas rau ntawm Monoprice Maker Xaiv Ntxiv
Hloov lub rhaub dej kub (lub rhaub dej kub) yog ib qho kev saib xyuas ntau tshaj plaws ntawm Monoprice Maker Select Plus (thiab nws ntau tus kwv tij txheeb ze zoo li Wanhao i3 Plus, Cocoon Tsim, thiab lwm yam). Txawm hais tias koj daim cartridge qub tau tsim lub voj voog qhib, muab qhov kub tsis sib haum, lossis tsuas yog tuag tom qab 2-3 xyoos ntawm kev ua haujlwm nyuaj, cov txheej txheem hloov pauv yog qhov yooj yim heev.
Nov yog qhov ua tau zoo, cov kauj ruam -los ntawm- cov lus qhia kauj ruam uas yuav tsum siv sijhawm ntau tus neeg 20–45 feeb thawj zaug.
Yam Koj Yuav Tsum Tau

Tshiab rhaub cartridge (feem ntau 12V 40W, 6 × 20mm, M3 × 20 teeb ntsia hlau hom)
Cov kev xaiv zoo tshaj plaws tam sim no (2025-2026):
tiag E3D lossis Slice Engineering
Keenovo / Aurora Tech / Aliexpress "UPRINT-3D" hom cartridges
Zam tsis txhob pheej yig tshaj tsis muaj- npe yog tias ua tau

Me me hex yuam sij (tsuas yog 1.5mm, 2.0mm, 2.5mm)
Phillips #1 thiab #2 screwdrivers
Koob-nose pliers (pab tau zoo heev)
Me me flathead ntsia hlau los yog spudger (kom ceev faj prying)
Kapton daim kab xev lossis siab -lub tes tsho kub (yeem tab sis pom zoo)
Thermal paste (nyias txheej, xaiv tau tab sis zoo)
Multimeter (muaj txiaj ntsig zoo rau kev kuaj mob thiab lees paub cov cartridge tshiab)

Kauj Ruam -los ntawm - Cov kauj ruam hloov pauv

Kev nyab xeeb ua ntej - tag nrho lub zog poob
Tua tawm thiab tshem tawm lub tshuab luam ntawv
Tos tsawg kawg yog 10 feeb tom qab luam tawm kawg (heatsink thiab cov xov hlau kub kub rau qhov xav tsis thoob ntev)
Tsis txhob ua haujlwm ntawm qhov kub kub thaum nws tseem sov

Tshem tawm cov kiv cua shroud / yas npog
Tshem tawm ob lub M3 screws nyob rau pem hauv ntej ntawm lub hnab yas kiv cua (feem ntau xav tau 2.5 hli hex)
Maj mam rub lub shroud downward thiab rau pem hauv ntej - nws feem ntau tuaj tawm yooj yim
Qee tus neeg tshem tawm ob lub 40mm txias kiv cua ntawm lub sijhawm no (4 screws tag nrho), tab sis nws tsis yog ib txwm tsim nyog.

Nkag mus rau lub rhaub thaiv
Koj yuav pom lub rhaub thaiv nrog:
rhaub cartridge (tuab liab / dawb / dub xaim tawm)
Thermistor (cov xov hlau nyias nyias, feem ntau yog iav hlaws)
nozzle hauv qab

Loosen lub rhaub cartridge teem ntsia hlau
Nrhiav cov ntsia hlau me me nyob rau sab ntawm lub rhaub thaiv (feem ntau xav tau 1.5mm hex key)
Tig tawm -clockwise kom txog thaum koj xav tias nws tso siab rau ntawm daim cartridge

Los yog siv rab koob- lub qhov ntswg pliers ntawm lub cev hlau ntawm daim cartridge (tsis txhob rub ntawm cov xov hlau!)
Pob zeb nws maj mam sab - mus rau - sab thaum rub

Ntxuav lub rhaub dej kub
Siv txhuam txhuam me me, txhuam hniav qub, lossis dov-paper sandpaper (400–800 grit)
Lub hom phiaj: tshem tawm cov qub thermal paste, oxidation, thiab txhua yam yas residue
Ib tug huv huv bore ua rau lub tom ntej no installation yooj yim dua

Npaj lub cartridge tshiab
Ntsuas qhov tsis kam ntawm cov cartridge tshiab nrog multimeter (yuav tsum nyeem ~ 3.0-3.8 Ω rau 12V 40W cartridge zoo)

Xyuas kom cov xov hlau yog taw qhia tib yam li qub (feem ntau yog cov tuab tuab liab / dub ob sab ntsej muag deb ntawm lub thermistor)

Nruab lub tshuab cua sov tshiab
Xaub nws hauv smoothly kom txog thaum nws tawm hauv qab (koj yuav tsum xav tias nws nres)
Thaum tuav nws tag nrho tso, nruj lub teeb ntsia hlau kom txog thaum snug
Tsis txhob nruj heev – ntiv tes- nruj + 1/4 tig yog txaus
Tshaj -tightening tuaj yeem tawg lub rhaub ceramic sab hauv

Hnav cov xov hlau
Route cov xov hlau tib txoj kev raws li ua ntej
Siv kapton daim kab xev los yog siab -temp lub tes tsho los qhwv lawv kom huv si
Xyuas kom cov xov hlau tsis tuaj yeem kov X lub tsheb thauj mus los lossis tau txais pinched

Reassemble txhua yam
Muab tus kiv cua npog rov qab (tsis txhob hnov ​​​​qab ob lub taub hau pem hauv ntej)
Muab ob npaug rau- xyuas tias tsis muaj dab tsi cuam tshuam rau cov xov hlau kub

Kuaj lub tshuab cua sov tshiab
Fais fab rau → mus rau Npaj → Preheat PLA (los yog 200 degree)
Saib qhov kub nce siab
Yuav tsum ncav cuag 200℃hauv 1.5-3 feeb
Let it sit at temperature for 5–10 minutes and look for large swings (>± 5 degree) - me me ± 1-2℃wiggles yog qhov qub
