Thaum kuv tau xaim 4-tus lej-7-ntu zaub rau kuv Teensy, Kuv txiav txim siab tias kuv yuav tsum pib tshawb fawb txog kev ua PCBs hauv tsev hauv txoj hauv kev yooj yim. Kev siv tshuaj ib txwm yog qhov ua rau nkees thiab txaus ntshai, yog li kuv tau muab pov tseg sai sai. Lub tswv yim zoo uas kuv tau pom ib puag ncig yog 3D luam tawm cov laug cam uas ua haujlwm ntxiv cov xim coj mus rau koj cov channel, tab sis qhov no zoo li tsis zoo rau kev coj ua. Kuj tseem muaj cov yeeb yaj kiab tshwj xeeb uas koj tuaj yeem siv ntawm ob lub tshuab luam ntawv extrusion, tab sis kuv tab tom nrhiav qee yam yooj yim thiab muaj txiaj ntsig zoo rau cov cuab yeej txheem uas kuv muaj.

Yog li kuv tau xav txog cov khoom siv ncaj qha thiab tso cov khoom sib txuas thiab cov khoom sib txuas ntawm 3D luam tawm.

Ua ntej peb pib, ceeb toom: peb yuav luam tawm nrog ABS vim nws tuaj yeem tiv taus +200ºC ua ntej deforming (yog li peb tuaj yeem ua tib zoo thov qee qhov siv rau ntawm nws). Kev luam ntawv nrog ABS tsis yooj yim li nws yog nrog PLA, koj xav tau lub tshuab luam ntawv kaw thiab ntau qhov teeb tsa 'ntsuas tab sis thaum koj tau txais txoj cai no, qhov tshwm sim ua qhov txawv.

Txhawm rau ntxiv qee cov ntsiab lus, hauv qhov piv txwv kuv tab tom tsim PCB rau ESP8266 12E wifi board yog li kuv tuaj yeem xaim nws mus rau lwm yam tom qab (lub hom phiaj kawg yog rau 4d7seg zaub).

PCB yuav cia kuv siv tag nrho nws cov pins muaj, thaum feem ntau cov qauv tawm muaj tsawg tsawg tus pin, lossis muaj ntau yam ntxiv uas kuv tsis xav tau tiag tiag (zoo li NodeMCU).

Thaum koj muaj PCB tsim hauv ntawv, koj yuav tsum muab nws qee qhov kev xav ntau dua hauv 3D qauv software. Qhov no tseem yuav npaj koj cov ntawv rau koj lub tshuab luam ntawv 3D. Nov yog qhov kuv ua hauv Blender:

  1. Tsim lub dav hlau ntxaij thiab ntxiv koj li PCB tsim duab hla nws. Nco ntsoov tias nws yog qhov ntsuas thiab qhov ntev yog qhov muaj tiag, vim qhov no yuav ua "ntawv taug qab".
  2. Tsim cov khoom yooj yim them nyiaj tshwj xeeb rau qhov chaw nyob thiab qhov loj ntawm PINS uas txuas rau koj li PCB. Tau txais cov chaw tsim khoom tshwj xeeb online lossis ntsuas lawv tus kheej kom tau txais qhov tseeb txaus. Nco tseg qee qhov qauv dims koj tuaj yeem siv ua qhov siv:

    1. Rau cov laug cam siv dav hlau. Rau ib sab PCB Kuv siv 1.5 hli tuab, raws li qhov me dua qhov no Kuv tsis tau txais cov ncauj lus kom ntxaws thaum luam ntawv (nws tseem yog qhov koj lub tshuab luam ntawv teeb tsa thiab muaj peev xwm, tab sis peb yuav tau nqis mus rau tom qab). Rau ob tog PCB kuv siv 2.5mm tuab.
    2. Rau cov pins siv lub tog raj kheej, yam tsawg 1 hli diametre txhawm rau kom nws ntes los ntawm lub tshuab luam ntawv.
    3. Rau cov channel siv ntsuas, yam tsawg kawg 1.2mm dav. Koj tsuas yog yuav nthuav tawm lub ntsej muag thiaj li tau txais koj cov channel.

  3. Nrhiav koj cov khoom siv raws li koj tus PCB tsim. Yog tias koj cov khoom muaj qhov txaus txaus, koj tuaj yeem siv qhov no txhawm rau txheeb xyuas kev sib tsoo, tab sis ib txwm tso cai rau qhov chaw ntxiv nyob ib ncig ntawm txhua ntu.
  4. Taug qab koj cov hluav taws xob hluav taws xob. Muab ib lub voos xwmfab mesh tso rau ntawm qhov chaw thawj tus pin. Tom qab ntawd, hauv kev hloov kho hom, tshem tawm lub ntsej muag hauv kab ncaj tom qab tsim. Ib zaug ntxiv, khaws nws yooj yim, siv 90º kab thiab siv ntau txoj hauv kev raws li koj xav. Tsis tas li, tso cai yam tsawg 0.8 hli sib cais ntawm phab ntsa lossis lwm yam lawv yuav ploj thaum luam ntawv. Daim duab 1 hauv qab no qhia qee qhov kev hloov pauv tom qab ua qauv nrog qhov ntev tiag, vim tias txoj kev zoo tshaj plaws yog nyias dhau los ua tau.
  5. Tsim koj li PCB los ntawm kev ntxiv ib lub voos xwmfab tiaj tus (dims li saum toj no).
  6. Sau koj cov channel thiab qhov ntawm lub rooj tsavxwm los ntawm kev ntxiv boolean hloov pauv rau koj cov khoom PCB. Qhov no yuav txiav tawm ntu ntawm pawg thawj coj saib xyuas uas yog lub hom phiaj ntawm kev hloov kho boolean.

Cov duab 3 thiab 4 qhia qhov txiaj ntsig kawg rau ESP8266 pawg thawj coj saib (qauv 3D hauv daim duab 2).

Tom qab qhov no, koj yuav tsum pom 3D luam tawm ntawm koj li PCB.

Kauj ruam kawg yog xa cov qauv kom raug.

  1. Nco ntsoov tias txhua lub ntsej muag taw rau sab nraud ("Kho kom raug hom - Xaiv Txhua Qhov" Tom qab ntawd "Ntxaij - Zoo ib yam - Rov suav dua sab nraum").
  2. Nco ntsoov tias lawv yog txhua tus neeg lub ntsej muag ("Kho Hom-Xaiv Txhua Tus" Tom qab ntawd "Ntug-Ntug Ntug").-Yog tias koj tso tseg ob kauj ruam no, koj yuav pom cov ntsiab lus ploj ntawm koj li software Slicer.--
  3. Export raws li. STL ("Xaiv Xwb" kom xa tawm tsuas yog PCB kawg thiab "Chav Scene" kom khaws qhov ntsuas ntawm yam khoom).

Cov tshuab luam ntawv 3D feem ntau muab cov "Slicer" software los ua cov qauv 3D (hauv.stl lossis lwm yam ntawv) thiab xam cov txheej txheem tsim nyog los luam nws (hauv.gcode hom ntawv feem ntau). Kuv muaj Creality Ender 3, thiab kuv tsis tau txav los ntawm Creality Slicer muab, tab sis koj tuaj yeem siv cov kev teeb tsa no rau lwm yam software.

Kuv tau txiav txim siab tag nrho ib feem rau kev txiav cov chaw raws li lawv yog qhov tseem ceeb heev thaum luam ntawv ABS, uas yog qhov nyuaj heev vim kev ua kom tawg, ntsws thiab tawg. Kev luam tawm PCB kuj tseem nyob hauv qhov txwv ntawm tus qauv 3D tshuab luam ntawv vim yog qhov yuav tsum tau ua.

Hauv qab no kuv tab tom qhia qhov kuv siv ntawm Creality Slicer rau ABS cov ncauj lus kom ntxaws luam ntawm PCBs. Lawv txawv ntawm cov qauv teeb tsa hauv:

  • Cov phab ntsa nyias nyias thiab txheej (kom muab cov ncauj lus txaus - qhov no yuav xav tau ob peb zaug rau koj qhov kev xav tau, tshwj tsis yog koj zoo siab nrog kuv teeb tsa).
  • Siv lub nkoj. Qhov tseem ceeb yog ntawm lub hauv paus, uas koj yuav tsum tau saib xyuas tshwj xeeb. (Kuv tso cai rau 10mm offset los ntawm tus qauv kom tsis txhob muaj qhov ntxeev tsawg los ntawm kev cuam tshuam rau luam ntawv). Tsis tas li, tsis muaj kev sib cais ntawm kab kab kom ua tiav lub hauv paus ruaj khov. Yog tias koj tau txais koj lub hauv paus raug, nws ua tiav. Yog tias koj pom ib lub ces kaum folding hauv koj lub hauv paus, koj yeej yuav tuag.
  • Qeeb qeeb. Kuv tab tom siv txog 1/4 ntawm tus txheej txheem nrawm (qhov no tso cai rau tso cov kab xev zoo thiab yog li ntawd lo thiab ua tau zoo tag nrho).
  • ABS kub (txaj: 110ºC, nozzle: 230ºC)
  • Cov kiv cua xiam oob qhab (pom zoo kom ua kom sov tas li rau ABS).

Thaum kawg, xa koj.gcode rau koj lub tshuab luam ntawv thiab tau txais koj li PCB tsim. Qee cov lus qhia koj yuav tsum ua raws:

  1. Kaw koj lub tshuab luam ntawv 3D. Ib lub thawv ntawv yuav ua rau koj qhov kub nyob ruaj khov dua, uas yog qhov yuav tsum tau muaj rau kev luam ntawv ABS. Nco ntsoov tias koj khaws CPU thiab lub zog xa hluav taws xob sab nraum lub thawv ntawv, nrog rau koj cov ntsiab lus. Yog tias koj tswj hwm luam tawm ABS yam tsis muaj qhov thaiv, thov qhia koj li kev dag vim nws ua rau kuv vwm.
  2. Preheat koj lub tshuab luam ntawv ib pliag. Ntawm PLA koj tuaj yeem luam tawm ncaj qha, tab sis nrog ABS kuv cov lus qhia yog ua kom sov nrog ABS teeb tsa (txaj: 110ºC, lub taub hau: 230ºC) rau 10-15 feeb yog li koj tsim qhov chaw zoo ua ntej koj tuaj yeem mus tom ntej thiab pib luam ntawv.
  3. Luam qeeb tab sis muaj tseeb. Raws li tau hais ua ntej, Kuv tau txo tus qauv luam ntawv ceev mus rau 1/4 hauv cov ntawv teeb tsa. Qhov no qhia kom qeeb txaus kom tau txais txiaj ntsig zoo, tab sis koj tuaj yeem tswj hwm kev luam ntawv thaum luam ntawv los ntawm kev tswj hwm tus nqi noj yog tias koj xav ua kom zoo dua me ntsis. Tsuas yog nco ntsoov tias kev nrawm nrawm yuav ua rau muaj kev txav mus sai heev uas yuav tsis tso cov kab ntawv ua tau zoo lossis tuaj yeem sib tsoo nrog lub mesh thiab tshem nws.
  4. Ua lub hauv paus zoo. Qhov tseem ceeb ntawm ABS yog kom ua tiav lub hauv paus ruaj khov. Yog tias lub hauv paus tsis ua tiav thiab tsis thim, tus qauv ploj mus (saib qee qhov kev puas tsuaj hauv qab no). Nrog cov lus qhia saum toj no (kaw, ua ntej cua sov thiab qeeb qeeb) koj yuav tsum tau txais lub hauv paus zoo thiab ua tiav zoo. Tab sis tsis zoo li PLA, uas kuv tso tseg tsis saib xyuas rau ntau teev, ABS xav tau kev saib xyuas ntau dua.
  5. Ceev faj, tshwj xeeb thaum pib. Rov hais dua qhov saum toj no, tus yuam sij yog lub hauv paus. Nco ntsoov tias thawj txheej sab nrauv tau zoo. Qhov no yuav tsav tus so ntawm thawj txheej nplaum. Qee zaum cov kab xev tsis lo ncaj qha lossis rub los ntawm nws qhov chaw. Koj yuav tsum pom qhov no sai txaus txhawm rau kho ib qib lossis ntxuav lub hauv paus phaj. Ib txwm saib rau kev ua phem, yog tias koj pom cov ces kaum nce lawv yuav zaum tsis thim tag nrho lub hauv paus thiab ua rau tag nrho cov ntawv puas. Txawm hais tias lub hauv paus tseem nyob hauv qhov chaw, kev ua rog yuav ua rau lub ces kaum no deformed.
