Qhov no ua rau nws yog txoj haujlwm zoo los qhia ob peb yam kev dag uas yuav ua rau koj lub neej yooj yim dua thaum tsim PCBs.

Txhawm rau qhia koj ob peb hacks yog li koj tau txais ntau dua ntawm Eagle, Kuv xaiv txoj haujlwm yooj yim uas kuv tau ua rau kuv Kickstarter. Kuv xav tau ib tus neeg tsav tsheb sab nraud rau kuv Ib Hnub Kev Sib Tw thiab kuv tsuas muaj 48 teev kom tau txais cov tsav tsheb stepper no. eBay tsuas yog pom cov uas los ntawm Tuam Tshoj thiab tsis muaj txoj hauv kev kuv tuaj yeem tau txais cov no mus rau hauv tebchaws Australia txog hnub kawg. Tau kawg eBay pheej yig dua ntawm $ 14 txhua qhov tab sis hauv qhov no kuv xaiv lub sijhawm yooj yim dua tus nqi.

Nco tseg: Kuv tau ntxiv Schematic thiab PCB yog li yog tias koj nyob tom qab TB6600HG CNC Mill stepper lub cev muaj zog tsav tsheb koj tuaj yeem rub tawm lawv thiab kho lawv raws li koj nyiam. Lawv tau ntsuas 4.5 Amps thiab ntau dua txaus los tsav NEM23s. BTW qhov no yog thawj qhov kev qhia kuv… ua yuam kev tshwm sim thiab kuv yuav kho lawv tom qab koj qhia kuv txog lawv.

Hauv Cov Lus Qhia Kuv yuav hla txhua qhov hack cais kom koj tuaj yeem xaiv thiab xaiv qhov koj xav tau.

1. Dimension ntawm PCB thiab ntsuas lawv

2. Npaj, tsim, sib sau ua ke txhua yam ua ntej ua ntej xaj thiab tsim khoom

3. Khaws cov PCB thiab cov tswv yim ua ke

4. Txheeb xyuas cov khoom

5. Kho cov ntawv lo lo lo ntxhuav

6. Hais kom PCB pheej yig thiab tsis pub dhau 48 teev

7. Kev xaj cov khoom pheej yig thiab tsis pub dhau 48 teev

Kauj Ruam 1: Kauj Ruam 1: Qhov ntev ntawm PCB thiab ntsuas lawv

Nws pom tseeb tias qhov teeb meem loj ntawm no. Koj xav tau qhov hneev taw me tshaj plaws tab sis tsis tsawg heev uas koj tsis tuaj yeem tso cov khoom siv los ntawm txhais tes lossis khaws thiab tso lub tshuab. Cov laug cam me me yuav hnyav dua thiab txuag koj tus nqi thauj khoom (uas feem ntau yog tus nqi loj tshaj).

Teem kab sib chaws rau 50 mills yog li koj cov khoom siv tau zoo tso thiab tsis dhau. Kos cov phiaj xwm phiaj xwm loj txaus kom tso rau qhov tho qhov thiab tso lawv ua ntej. Koj tuaj yeem txav lawv ib txwm thiab koj yuav ua.

Siv DRC Cov Cuab Yeej los tshuaj xyuas ib qho ntawm cov khoom sib tshooj

Teem qhov loj me hauv kab Cuab Yeej rau 10 mil (default 6 mil). Qhov no cuam tshuam nrog tooj liab tuab ntawm koj li PCB. Hauv qhov no nws yog pawg tswj hwm lub zog yog li peb xav tau 2 Oz Cu tuab. Cov chaw tsim khoom PCB tsis tsim 6mil lem nrog 2 Oz Cu.

Muab tag nrho cov khoom tso rau ntawm PCB thiab xaiv txheej txheej. Xaiv cov cuab yeej ntsuas thiab nyem los ntawm ib sab ntawm pawg thawj coj saib mus rau lwm sab. Cov kauj ruam no qhia txog qhov ntev thiab tam sim no rub tus nas mus rau sab nraum PCB thiab tso mus. Tam sim no qhov ntev sawv tawm thiab nyeem tau. Yog tias koj xav rho tawm qhov ntev dua, xaiv txheej txheej txheej thiab mus rau nruab nrab ntawm qhov ntev thiab nyem rho tawm. Nws rhiab heev thiab koj yuav tsum nyem raws nraim hauv nruab nrab ntawm kab kab. Yog tias kab nyob saum koj daim phiaj phiaj xwm koj pom qhov teeb meem. Koj tsis tuaj yeem mus rau txoj kab ntawd. Qhov ua kom yuam kev yog kom txav ib leeg deb ntawm ib leeg dhau ntawm Cov cuab yeej txav.

Ib txoj hauv kev zoo ib yam koj tuaj yeem ntsuas qhov nrug nruab nrab ntawm qhov laum/mounting qhov ntawm kaum ntawm koj li PCB. Tom qab txaus siab rau lawv qhov chaw, koj tuaj yeem tshem tawm cov kab ntsuas.

Kauj Ruam 2: Kauj Ruam 2: Npaj, Tsim thiab Sib Raug Zoo Txhua Yam Ua Ntej

Tsis muaj dab tsi nyuaj siab ntxiv thaum koj tsis tuaj yeem tso lub dab dej sov vim tias koj hnov qab tias tsis muaj txoj hauv kev kom tau mus rau cov ntsia hlau thiab ntsia liaj qhov rooj thaum koj xauv lub hwj chim nti, hauv qhov no TB6600 mus rau PCB.

Cov piv txwv kev lag luam qhia tias lawv siv cov chaw tsim khoom uas twb muaj lawm khoov tus pin thiab ntxiv qhov hla lub PCB los ntsia hlau hauv lub dab dej kub. Cov laug cam no tau muag rau $ 14 ntawm eBay yog li koj tau txais cov lus tias qhov no tej zaum ua tiav sai thiab pheej yig los ntawm cov neeg ua haujlwm tsis muaj txuj ci. Tsis txhob sawv ntsug lossis cov ntoo ntawm PCB thiab cov cua sov. Tab sis lawv tau npaj nws kom nrawm thiab nrawm.

Kuv tus PCB tab tom ntxiv daim nyias nyias ntawm 3mm acrylic ntawm PCB thiab lub hwj chim nti los tso rau hauv qhov chaw. Tsis zoo tagnrho tab sis rau qhov xwm txheej no nws ua rau lub tswv yim zoo. Qhov sawv ntsug yog qhov loj me.

Qhov ua kom yuam kev ntawm no yog kom luam tawm PCB txheej txheem ntawm daim ntawv, ntsuas 1: 1 thiab lo nws mus rau ob peb seem ntawm PCB cov khoom uas kuv tau tso ib puag ncig. Laum lub qhov thiab sim ua kom sib dhos PCB tsis zoo no thiab sai sai koj nthuav tawm cov teeb meem thiab seb qhov kev txiav tawm puas yog.

Txhawm rau tsim Kev Txiav Tawm, koj kos rau hauv tKeepout thiab tRestrict Layers ib lub xwmfab los ntawm kev kos plaub kab. Ua tib yam rau txheej hauv qab, bKeepout thiab bRestrict. Sau rau hauv tNames txheej lo lus "Txiav Tawm", yog li PCB cov chaw tsim khoom yuav paub tias qhov no yuav tsum tau ua.

Kuv xaiv siv txoj hlua sib txuas ntau dua li hla lub qhov vim tias tam sim no thiab ze ntawm qhov nyob hauv cov qauv coj mus muag. Qhov teeb meem ntawm no yog tias Eagle lub tsev qiv ntawv tsuas yog hla lub qhov taw taw.

Hauv Schematic, Nyem rau ntawm Info tool lossis Group tool los xaiv Power Chip thiab txoj nyem rau ntawm Open Device lossis Symbol.

Xaiv hneev taw thiab koj yuav pom qhov tseeb ko taw sau ntawm cov khoom. Qhov ua kom yuam kev ntawm no yog hloov pauv puag ncig los ntawm cov pawm rau txoj kab sib dhos.

Qhov kuv tau ua yog siv SMD cov xim rau cov menyuam thiab kos cov kab hauv qab ntawm tus kheej lub ncoo (saib cov duab). Tom qab ntawd kuv hloov npe cov lem los ntawm kev siv lub npe yuav luag zoo ib yam li cov ntaub qhwv saum toj no. Kuv hloov ntawm txheej txheej saum toj thiab hauv qab vim yog txoj kab nqes ntawm TB6600 nti (nws muaj kab saum toj thiab kab hauv qab). Tom qab npe lawv txhua tus, Kuv tshem cov ntaub qhwv thiab txav cov kab mus rau txoj haujlwm uas kuv xav tau.

Tom ntej no yog txuas cov npe tshiab rau lub cim. Nyem rau ntawm lub cuab yeej nyob rau sab saum toj kab ntawv qhia zaub mov bar, xaiv Txuas hauv lub pop up thiab koj pom txhua lub cim cim thiab tus hneev taw. Txuas lawv ib leeg los ntawm ib qho los ntawm Kev Txuas thiab koj ua tiav. (saib screenshot)

Thaum koj muaj ntau tus pin txuas rau piv txwv li hauv av ces siv txuas ntxiv kom lawv txuas nrog ua ke.

Lwm qhov ua kom yuam kev yog cov ntaub qhwv cua sov. Qee qhov xwm txheej, zoo li kev sib txuas koj xav tau lub ncoo ruaj khov thiab tsis yog lub ncoo cua sov (muaj qhov khoob hauv cov ntaub qhwv). Hauv qhov hneev taw, koj nyem rau ntawm lub ncoo, xaiv Cov Khoom thiab de-xaiv Thermal xaiv. (saib screenshot).

Txhawm rau kom muaj suab nrov tsawg thiab tso cai yooj yim, peb ntxiv lub dav hlau av rau saum thiab hauv qab. Siv lub cuab yeej Polygon los ntawm sab laug Tool ribbon (5 sab pob zeb zoo li tus cim). Kos ib lub xwmfab puag ncig los ntawm kos ib kab, nyem, kos kab tom ntej kom txog thaum koj mus txog qhov pib ntawm lub ntsej muag thiab tam sim no ceev faj. Zoom hauv los ntawm kev tig koj lub log log nas thiab nyem rau ntawm qhov pib ntawm Polygon. Rov ua dua rau lwm txheej thiab nyem rau ntawm Ratnest lub cuab yeej nyob rau sab laug Tool ribbon ntawv qhia zaub mov. Nws dej nyab puv koj lub PCB nrog liab thiab xiav. Tsis txhob txhawj xeeb tias koj tseem tsis tau hloov lub rooj tsavxwm.

Tom qab cov kev hloov kho no, koj tus kheej qhia cov laug Hwj Chim Lub Hwj Chim thiab Cov Kab Txuas thiab tshawb xyuas tias cov khoom sib txuas yog txhua yam nyob rau hauv kab lus raug. Zoom rau hauv tus pin ntawm tus txuas thiab nyeem daim ntawv lo. Puas yog eg 'GND' ua. Puas yog peb pauv 'GND' thiab piv txwv li 'ENB' puag ncig. Peb xav kom GND zoo ib yam ntawm sab laug lossis sab xis ntawm txhua lub dav hlau ntsia hlau. Tam sim no pib nws txoj hauv kev seem. (Left Tool ribbon menu "Pib txoj kev")

Thiab ntawm chav kawm txheeb xyuas ua ntej ntawm Octopart.com seb koj cov khoom puas muaj hauv Tshuag thiab tus nqi tsim nyog! Octopart cia koj ntshuam BOM los ntawm Eagle kom koj tuaj yeem pom sai sai tus nqi tag nrho rau PCB.

Kauj Ruam 3: Kauj Ruam 3: Khaws PCB thiab Schematic hauv Sync

Qhov no yuav yog koj lub sijhawm txuag tshaj plaws. Txhua lub sijhawm qhov no dag kuv thiab poob haujlwm ntau.

Ua kom ntseeg tau tias koj muaj PCB thiab cov kws kho cov duab qhib txhua lub sijhawm. Yog tias koj hla lub rooj tsavxwm thiab txuag yog tias thaum lub phiaj xwm raug kaw, koj xoob qhov sib txuas thiab Eagle yuav qhia koj tias lawv tsis sib xws thiab tsis tuaj yeem piav qhia tom ntej lossis rov qab.

Feem ntau koj yuav tsum hla txhua txoj hauv kev thiab pib dua. Qhov no raug nqi tshwj xeeb tshaj yog tias koj xaj cov laug cam ua ntej thiab kho cov teeb meem me me. Koj xoob cov txiaj ntsig rov ua dua ntawm kev kho yav dhau los thiab qhia qhov tshiab.

Qhov ua kom yuam kev ntawm no yog kom tau txhua yam npaj rau kev hloov pauv thiab txuag lub PC/Schematic thiab txuag dua hauv qab lub npe tshiab lossis tus lej. Cov ntawv tshiab ntawd yuav raug xa mus thiab koj tuaj yeem rov qab mus rau kauj ruam dhau los.

Tsis tas li tom qab taug kev, tsis txhob txuag lub rooj tsavxwm kom txog thaum koj zoo siab. Yog tias tsis yog, tsis txhob txuag lub rooj tsavxwm tab sis kaw PCB thiab Schematic thiab pov tseg cov kev hloov pauv. Rov qhib Schematic thiab PCB thiab rov ua dua kom txog thaum koj zoo siab thiab txuag lub rooj tsav xwm zaum kawg.

Tom qab nrhiav qhov teeb meem tshiab, txuag nws dua li hloov tshiab. Rip-up tsuas yog txoj hauv kev uas muaj teeb meem thiab kho nws.

Kauj Ruam 4: Kauj Ruam 4: Rov suav tus lej

Muaj qhov kev xaiv nyob rau sab saum toj kab ntawv qhia zaub mov kom rov suav tus lej tab sis kuv ntaus lub snag.

Cov ntawv qhia zaub mov tau tshwm sim hais tias qee qhov tsis muaj kev kho ua ntej thiab kuv yuav tsum kho nws, hloov kho lub tsev qiv ntawv thiab rov ua dua.

Ib zaug ntxiv xaiv ib feem uas ua rau muaj teeb meem thiab nyem rau ntawm lub cuab yeej icon nyob rau sab saum toj kab ntawv qhia zaub mov lossis nyem txoj cai ntawm tus tivthaiv thiab xaiv Ntaus hauv PCB tus kws kho mob.

Xaiv cov ntawv kho kom raug los ntawm kab saum toj kawg nkaus thiab xaiv Ua Ntej (IC cim saib cov duab).

Nkag mus ua ntej ua ntej zoo li tsab ntawv (s) rau Cov Ntaus xws li Capacitor yog 'c'.

Txuag nws thiab rov qab mus rau Schematic editor thiab rov suav tus lej. Siv qhov ua tsis tau zoo xws li X thiab Y kev taw qhia thiab nws ua haujlwm tau zoo yog tsis muaj kev sim nrog kev teeb tsa. Tam sim no txhua yam tau suav zoo hauv PCB ib yam.

Kauj Ruam 5: Kauj Ruam 5: Txhim Kho Cov Ntawv Silk Screen

Hauv lub neej ua ntej, koj tau txais cov ntawv lo lo lo ntxhuav loj heev uas cuam tshuam ntau.

Yog li peb yuav tsum rov ua qhov loj me ntawm daim ntawv lo lo lo ntxhuav tName cov ntawv. Kuv tsis txhawj xeeb ntau nrog tValues vim tias kuv tso lawv ntawm silkscreen. Ua li ntawd nws tsawg dua pawg neeg thiab nyeem tau ntau dua.

Yog li peb yuav ua li cas? Zoo Google nyob ntawm no koj tus phooj ywg.
