Lub tswv yim ntawm txoj haujlwm yog txhawm rau tsim 3D luam tawm, Raspberry Pi raws cov ntsiav tshuaj. Txhua ntu (cov khoom siv) yuav tsum yooj yim kom tau txais thiab npaj tau. Nws yuav tsum muaj roj teeb, thiab nws yuav tsum yog lub hauv paus tseem ceeb ntawm lub zog (lub ntsiab lus, nws yuav them nrog lub xov tooj txuas nrog, tab sis yuav tsum muaj lub zog txaus los khiav yam tsis muaj nws.) Nws yuav tsum muaj peev xwm ua haujlwm tau zoo yam tsis muaj keyboard (lub ntsiab lus, txhua yam hauv tus neeg siv interface yuav tsum ua haujlwm yam tsis muaj teeb meem txawm tias koj tsis muaj keyboard thiab nas ntsaws rau hauv.)

Nco tseg: Txoj haujlwm no siv Raspbian OS rau tam sim no, txog thaum kuv tuaj yeem pom qhov tsim nyog "kov-ua ntej" kev daws teeb meem.

Kauj ruam 1: Yuav Ua Li Cas Yees Duab

Thov Nco Ntsoov: Cov vis dis aus suav nrog kaw cov ncauj lus kom ntxaws ntawm txhua cov kauj ruam uas kuv tau ua kom ua tiav txoj haujlwm no. Thov saib cov vis dis aus lossis ua raws cov theem hauv qab no txhawm rau ua txoj haujlwm no rau koj tus kheej.

Kauj Ruam 2: Npaj Cov Cheeb Tsam

Hauv theem no koj yuav tsum tau hloov kho qee qhov uas koj tau xaj. Qhov no feem ntau yog siv qhov hnyav xws li cov thawv ntsia hlau thiab lub thawv USB thiab lwm yam, tawm ntawm PCB, raws li peb yuav muab cov hlua txuas rau lub rooj tsavxwm.

1. Raspberry Pi: Saj tawm USB thaiv thiab thaiv lub network (tsis txhob muab cov khoom pov tseg, siv lub tshuab txiav, nqa cov hlau thaiv, thiab txiav cov yas tawm). Kuj tshem tawm txhua tus GPIO pins tshwj tsis yog sab saum toj 6 (raws li daim duab sib dhos)
2. LCD: Tshem lub USB thaiv los ntawm PCB, thiab tshem ob ntawm 12mm tus pin nyob tom qab.
3. PiJice: Tshem lub yas yas yas yas yas. Tshem cov yas yas dub rau cov GPIO pins, thiab tom qab ntawv txiav (tsis txhob muag) GPIO tawm tsuas yog sab saum toj 6 tus pin (3 ntawm sab xis, 3 ntawm sab laug).
4. HW-517: Tshem cov ntsia hlau thaiv (tsis muag)
5. wm8960: Tshem cov yas yas dub rau lub GPIO, thiab tus hais lus cable thaiv thiab ntsia hlau, tom qab ntawv txiav GPIO raws li daim duab qhia.
6. Ntxuam: Tshem lub rhaub dej kub

Kauj Ruam 3: Luam Ntawv 3D

Koj tuaj yeem rub tawm txhua cov ntaub ntawv koj xav tau hauv qab no. Kuj tseem muaj daim ntawv theej ntawm Thingiverse, yog li koj tuaj yeem siv 3D kev pabcuam luam ntawv yog tias koj tsis muaj.

Tswv yim 3D luam ntawv:

Muaj qee yam txog Creality lub tshuab luam ntawv uas yuav cawm koj ntau qhov ua tsis tau tiav … Lawv cov iav nto yog qhov txaus ntshai rau luam tawm, thiab txawm tias cov phaj tsim yuav raug cua sov, nws muaj yuav luag tsis muaj cov nplaum thiab kuv feem ntau tsis siv lub brim. los yog dab tsi … ua li cas? Kuv ntxuav lub iav nrog cawv dawb, thiab tom qab ntawd siv cov ntawv nplaum ib txwm ua Pritt Stick. Nws yog cov kua nplaum uas tsis muaj tshuaj lom thaum ua kom sov (zoo li los ntawm lub txaj) yog nplaum heev, thiab sib txuas PLA rau cov phaj tsim. Tom qab ntawd thaum luam tawm tiav thiab tsim cov phaj txias, nws tsuas yog tawm yooj yim. Yog tias koj maj nrawm, koj tuaj yeem ntxuav nws nrog dej. (koj yuav tsum tau ntxuav lub iav tawm hauv txhua rooj plaub tom qab txhua qhov luam tawm)

Kauj Ruam 4: Tom Qab Luam Ntawv

Kua nplaum txhua txheej ua ke nrog cov nplaum nrawm super los yog qee yam sib npaug. Cov txheej yuav tsum zaum kom zoo nyob saum ib leeg. Txheej 1 thiab 2 muaj cov ntawv me me uas pab ua kom sib tshooj.

Nqa cov yas yas uas tawm los ntawm PiJuice, thiab muab cov kua nplaum tso rau hauv qhov chaw muab hauv Txheej 2

Tam sim no nws tau lo, koj tuaj yeem xuab zeb rooj plaub kom nws zoo nkaus li zoo!

Txhawm rau kom tau txais koj cov ntaub ntawv zoo meej, koj yuav tsum tau xuab zeb. Kuv siv cov hauv qab no:

1. Rough xuab zeb nrog 100 pob zeb, yog li txhua kab txheej raug tshem tawm. Cov yas sab nrauv ntsia sab nrauv zoo li grey thiab yog ntxhib heev, tab sis tsis muaj cov kab uas pom pom, lossis cov yas me me.
2. Ua kom du - nrog 400 txog 800 cov ntawv xuab zeb, pib ua haujlwm ntawm cov tawv nqaij kom du thiab du kom txog thaum nws tsis muaj qhov sib txawv yog tias koj tab tom ua haujlwm, PLA tseem yuav zoo li khawb me ntsis.
3. Brasso - Siv cov hlau txhuam kom zoo ib yam li Brasso, kom muab cov yas ua tiav zoo kawg nkaus.
4. Thaum kawg txau ib lub tsho ntawm Tiaj Tsuag Dub tsuag xim. Koj tuaj yeem siv ib qho (Kuv siv Rust-oleum) tsuav nws txuas nrog yas.

Kauj Ruam 5: Txuas Cov Khoom Siv

Siv daim duab kab xaim los xaim tag nrho cov khoom siv kom txhua qhov khoom siv txuas nrog nws cov xim sib thooj. Thaum koj tau ua tiav qhov no, koj tuaj yeem ntxig cov laug cam rau hauv rooj plaub, thiab koom nrog cov xov hlau ua ke.

Kauj Ruam 6: Laser Etching Ntoo Backplate

Cov kauj ruam no yuav xav kom koj muaj lub laser txuas rau koj lub tshuab luam ntawv, zoo li Ender 2. Qhov no siv PWM ntawm tus kiv cua nrawm xws li lub zog tswj rau lub laser. Thaum lub kiv cua puv, ces lub laser puv, thiab yog tias tus kiv cua hais 10% ces lub laser tab tom hlawv me ntsis rau hauv ntoo xwb. Qhov tshwm sim yog muaj peev xwm "khawb" rau saum npoo zoo li ntoo. Lub gcode kuv siv tau muab - nws teev qhov siab ntawm lub laser mus rau 50mm, yog li nco ntsoov ua kom pom tseeb ntawm lub laser raug ntawm 50mm.

Tsis teb los tau: Koj kuj tuaj yeem tsim koj tus kheej tsim yog tias koj nyiam, tab sis tom qab ntawd koj yuav tsum mus rau qhov chaw no:

Ntoo yuav tsum tau txiav rau 112mm x 230mm, thiab koj yuav tsum tau xuab zeb ciam teb kom haum rau Txheej 3
