Yuav Ua Li Cas Hloov Kev Nyab Xeeb Kev Nyab Xeeb rau K40 Laser Cutter: 4 Cov Kauj Ruam (nrog Duab)

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27

Tseem ceeb kho! Thov tsis txhob xaim koj cov kev sib txuas mus rau lub ntsiab ntawm lub tshuab. Hloov chaw xaim rau PG pins ntawm PSU. Yuav ua qhov hloov tshiab tag nrho sai. -Tony 7/30-19

Dab tsi yog ib qho ntawm thawj cov lus qhia hauv is taws nem rau thaum twg koj lub npe tshiab, (tej zaum) ci K40 laser txiav pom tshwm? Txhim kho cov khoom sib tshuam!

Dab tsi yog qhov hloov pauv? Yeej tsuas yog hloov pauv (hauv peb kis, microswitch), uas tau teeb tsa nyob ze ntawm lub hau ntawm lub tshuab. Yog tias lub tshuab ua haujlwm thiab koj nqa ib lub hau, qhov hloov pauv yuav txiav tawm thiab txiav lub zog rau lub tshuab. Lub tswv yim ua haujlwm zoo ib yam li khawm nres xwm txheej ceev, tshwj tsis yog koj tsis xav tau, yuav tsum nias dab tsi.

Yog li thaum kuv ua siab ntev tshawb fawb lub tshuab twg kuv yuav yuav, Kuv tseem tab tom tsim cov npe hloov khoom dua tshiab uas tau tshwm sim ua ntej lub tshuab laser tau qhib. Kev nyab xeeb ua ntej! Qhov teeb meem tseem ceeb uas kuv tau tshawb pom txog kev txhim kho kev sib hloov hloov pauv yog tias tsis muaj ntau txoj hauv kev zoo uas yog (1) yooj yim; (2) sau rau cov kws tsis siv hluav taws xob; (3) muaj cov ntaub ntawv zoo.

Yog li phau ntawv qhia no yog rau txhua tus neeg nyob ntawd uas xav tau 100% kev ua tau zoo, nrawm, thiab muaj kev nyab xeeb los xaim xov txuas sib txuas rau koj li K40 laser.

Yam Yuav Tsum Tau:

• (3) End -Stop Style Microswitches - Feem ntau pom ntawm 3D tshuab luam ntawv, tshwj xeeb tshaj yog cov khoom siv Prusa. Koj tuaj yeem siv txoj kev xav tsuas yog siv cov jane microswitches dawb xwb, tab sis kuv txiav txim siab siv 5-6 daus las kom tau cov no uas tau teeb tsa ntawm cov laug cam thiab tuaj wired npaj mus. Tsis tas li, Don los ntawm Don's Laser Cutter Things, muaj cov phiaj xwm rau qhov kawg-nres hloov pauv uas muaj qee yam ntxiv ntawm nws. Ua siab ncaj, tsis paub yog vim li cas, tab sis kuv tau dov nrog Don.
• Me me, PCB dawb paug - Kuv tau tshwm sim muaj ib qho ntawm Adafruit sawv ntawm ib puag ncig uas kuv tau siv
• Jumper Wire - Kuv nyiam tau txais cov tub ntxhais hlau rau cov no
• Txiv neej Header Pins
• 2 Pin Ntsia Hlau Terminal Mount - Feem ntau, thaum kuv mus rau qhov ua ntu PCB, koj tuaj yeem hloov cov khoom no rau yam koj xav tau lossis muaj ntawm tes.
• 3M Mounting Daim Kab Xev (koj ib txwm tuaj yeem tho qhov thiab ntsia liaj qhov rooj ntawm)
• Kub Shrink Tubing (xaiv tau, tab sis ua koj tus kheej nyiam thiab tau txais qee yam)

Yuav tsum tau cov cuab yeej:

• Soldering Iron (koj tuaj yeem zaum rub qhov no yam tsis muaj ib qho, tab sis tuaj, koj yuav xav tau sai sai yog tias koj yuav koj tus kheej K40)
• Cov Hluav Taws Xob Hluav Taws Xob, Cov Hluav Taws Xob Hluav Taws Xob, Koob Lub Qhov ntswg (thaum koj tsis xav tau cov khoom no ??)
• Ntsia hlau tsav tsheb

IB LUS QHIA TSEEB KAWG FINAL NOTE

Kuv lub tshuab tuaj nrog qhov hloov chaw nres xwm txheej ceev, uas kuv tab tom yuav siv rau hauv peb cov thaiv, uas tseem ua rau nws yooj yim heev. Yog tias koj tsis muaj e-nres, koj yuav tsum tau ua ntawm koj tus kheej txoj kev pheej hmoo ntawm kev txiav cov xaim zoo uas nkag mus rau hauv lub zog hloov pauv. Yooj yim txaus, tab sis kuv yuav tsis qhia qhov ntawd.

Kauj Ruam 1: Kauj Ruam 1: Nkag Siab Yuav Ua Li Cas Interlocks Yuav Siv Tau

Zoo, yog li cia peb mus nrog hluav taws xob.

Peb cov txheej txheem rau kev txhim kho cov hloov pauv hloov pauv yuav yog coj mus rhaub khawm khawm thaum muaj xwm ceev ntawm lub tshuab. Kuv cov ntaub ntawv nyoos tom-nws sau cov duab piav qhia.

Peb yuav mus…

1. Tshem tawm cov xaim mus rau hauv e-nres los ntawm PSU
2. Khiav cov xaim ntawd mus rau ib qho ntawm peb cov kev sib txuas sib txuas
3. Khiav hlau ntawm txhua qhov hloov pauv (sib npaug) yog li txhua qhov hloov pauv, suav nrog e-nres, yuav tsum raug kaw kom lub tshuab ua haujlwm.

Muaj ntau txoj hauv kev uas tib neeg tau thov, siv cov hlau nplaum sib nqus reed, thiab txhua yam khoom. Qhov no zoo li yuav tsis zoo nkauj.

Kauj Ruam 2: Kauj Ruam 2: Qhia Txog Qhov System Ua Haujlwm Li Cas

Yog li thawj ob daim duab koj tuaj yeem yuav luag xav tias yog peb li e-nres. Txawm hais tias koj nias hauv e-nres khawm kom koom nrog nws, thaum nws tsis tau nias qis, nws tau tso cai tam sim no kom ntws ncaj qha los ntawm nws.

Kom paub tseeb tias kuv xav ua dab tsi yog txoj hauv kev mus tiag tiag, Kuv tau sim nrawm siv lub khob cij thiab ob peb lub microswitches kuv muaj nyob ib puag ncig.

Ua ntej kuv txuas 1 microswitch (hu rau peb qhov e-stop hloov), thiab nws ua haujlwm. Tom qab ntawd kuv ntxiv 3 microswitches ntxiv los sawv cev rau txhua tus ntawm 3 tus hloov pauv peb yuav ntxiv. Lawv tau xaim ib yam li kuv qhov post-it note schematic in the first part. Txhua yam ua haujlwm thiab kuv ntseeg tias txhua yam yuav ua haujlwm tau zoo.

Qhov kev xeem zaum kawg uas kuv tau ua, tau lob ib qho ntawm kuv qhov kawg-nres thiab qee cov kais dej thiab ua kom nws txuas mus rau e-nres thiab tig lub tshuab nrog ib qho kev sib hloov hloov pauv kom pom tias nws ua haujlwm li tau npaj tseg. Yog, txhua yam zoo.

Tam sim no cia peb ua me ntsis so tawm board.

Kauj Ruam 3: Kauj Ruam 3: Ua Pawg Txiav Txim rau Koj Cov Hloov

Ib feem no xav tias koj muaj qee qhov txuj ci hluav taws xob yooj yim thiab paub yuav ua li cas txhawm rau ua thiab ua cov PCBs yooj yim, ua los ntawm tes.

1. Pawg thawj coj uas kuv tau ua yog yooj yim heev. Kuv xaim 4 teeb ntawm 3 tus txiv neej header pins ntawm PCB thiab muag lawv.
2. Tom qab ntawd kuv tau khiav jumper wired nyob nruab nrab ntawm txhua qhov kev sib txuas sib txuas, ib zaug ntxiv, zoo ib yam li kuv cov ntawv tom qab-nws ceeb toom schematic, thiab yuav ua li cas peb xaim cov hloov pauv ua ke ntawm lub khob cij.
3. Kuv muab 4 teeb tso rau ntawd, koj tsuas yog yuav tsum ua 3 tab sis. Kuv muab tus thib 4 nyob rau ntawd zoo li yav tom ntej kuv xav ntxiv lub ntsuas dej ntws mus rau kuv lub cev thiab kuv tuaj yeem ntsaws nws rau hauv. Kuv tso me ntsis homebrewed jumper cov pins.
4. Cov laug ntawm koj 2-Pin Screw Terminal Connector thiab xaim txhua qhov kawg rau qhov pib thiab qhov kawg ntawm kev sib tshuam hloov header pins.
5. Yog tias qhov no tsis yog piav qhia tus kheej, thov tawm lus.
6. Kuv xav tias tsuas yog ntxiv qee qhov 3M daim kab xev rau tom qab ntawm nws. Kuv nyiam siv cov khoom no vim tias nws muaj zog heev, thiab nws ua raws li cov insulator zoo thaum txhim kho cov khoom hlau zoo li rooj plaub no (tsis zoo) wired laser txiav.
7. Raws li koj tuaj yeem pom hauv cov duab kawg, Kuv tsuas yog coj cov hlau mus rau hauv e-nres, txiav nws hauv ib nrab, coj sab nrog xaim xaim thiab ntxiv qhov ntev ntawm cov hlau rau qhov ntawd thiab tseem ntxiv qhov ntev ntawm xaim rau lwm qhov kawg ntawm cov xaim txiav.

Yuav luag tiav!

Kauj Ruam 4: Kauj Ruam 4: Txhim Kho Koj Lub Rooj Tswjhwm Saib thiab ntsaws txhua yam

Thiab hais txog nws!

Txuas lub e-nres cov xov hlau mus rau sab xis ntawm lub hau ntswj.

Ntsaws rau hauv cov interlocks (xyuas kom tseeb tias kev taw qhia raug.

Thiab qhov no yog qhov uas kuv yuav cia koj txoj kev ntse thiab kev muaj tswv yim ua tiav. Koj tuaj yeem pom qhov twg kuv tau txiav txim siab rub ob qho ntawm kuv rau sab xub ntiag. Kuv yuav tsum tau ntxiv ib yam dab tsi kom lawv koom nrog thaum lub hau tseem raug kaw. Yog tias koj muaj gottten nyob deb no, Kuv paub tseeb tias koj tuaj yeem txiav txim siab yuav ua li cas txhawm rau txhim kho lawv. Yog tias koj muaj lub tshuab luam ntawv 3D, hla mus rau ntau yam, muaj ntau tus qauv tawm muaj thiab.
