3D luam tawm STL cov ntaub ntawv txuas nrog. Kuv siv Creality Ender 3 nrog 1.75mm PLA dawb.

Nov yog cov teeb tsa kuv siv:

  • Tus nqi: 20%
  • Txheej qhov siab: 0.2 hli
  • Nozzle kub: 200 ° C.
  • Lub txaj sov: 60 ° C.

Cov txheej txheem luam ntawv tag nrho siv sijhawm li ib teev nrog cov teeb tsa saum toj no. Yog tias koj tsis muaj lub tshuab luam ntawv 3D koj tuaj yeem siv daim duab los ua!

Tom qab koj ua tiav luam tawm koj yuav tsum muaj ob ntu. Hauv cov kauj ruam no peb yuav sib sau cov catapult.

  1. Coj tus ntsia liaj qhov rooj thiab siv tus ntsia hlau ntsaws rau hauv lub qhov nruab nrab ntawm ib feem uas zoo li rab diav.
  2. Lob cov hlua roj hmab thiab ruaj ntseg nws nyob ib ncig ntawm ntsia liaj qhov rooj nrog cov txiv ntoo. Siv me ntsis kua nplaum kub yog tsim nyog.
  3. Siv cov cuab yeej txhawm rau ncaj cov ntawv txiav thiab txiav nws ib nrab.
  4. Muab ib nrab ntawm daim ntawv tso rau hauv lub qhov ntawm ob qho 3D luam tawm thiab khoov qhov kawg kom ntseeg tau tias txhua yam nyob hauv qhov chaw.

Cov servos:

Peb pib tawm nrog servos. Txuas cov xaim daj ntawm thawj servo rau tus pin 5. Qhov no yuav yog servo los tua cov catapult. Txuas cov hlau daj ntawm qhov thib ob servo rau tus pin 9. Qhov no yuav yog lub xauv servo. Txuas cov xov hlau liab ntawm ob qho kev pabcuam rau sab zoo ntawm lub khob cij thiab txuas cov xaim xim av ntawm ob qho kev pabcuam rau sab tsis zoo ntawm lub khob cij. Kuv siv qee lub xov hlau jumper los txuas cov servos tab sis lwm cov xov hlau yuav ua haujlwm ib yam.

Khawm:

Solder tus resistor rau lub khawm thiab txuas lub xaim mus rau lwm qhov kawg ntawm tus tiv thaiv. Muab ob lub xov hlau txuas rau lub pob raws li qhia hauv daim duab. Txuas cov xaim daj rau tus pin 7 ntawm Arduino, txuas cov xaim liab mus rau qhov zoo ntawm lub khob cij thiab lub xaim xaim xiav rau sab tsis zoo ntawm lub khob cij.

Txuas qhov zoo ntawm lub khob cij rau 5v thiab txuas qhov tsis zoo ntawm lub khob cij rau hauv av (GND tus pin).

Sawb lub USB cable kom tau txais ib txoj hlua uas ib kawg yog USB nkag thiab lwm qhov kawg yog ob lub xov hlau. Txuas cov xaim liab ntawm USB cable nrog VIN tus pin ntawm Arduino thiab lwm qhov nrog hauv av (GND tus pin). Lub Circuit Court tau ua tiav thiab peb tuaj yeem pib coding!

Kauj ruam 5: Txoj Cai

Txoj Cai!
Txoj Cai!

Hauv theem no peb yuav sau cov cai los tswj cov servos. Peb yuav siv Arduino uno los ua li ntawd. Cia peb pib!

Qhib Arduino IDE thiab import cov ntaub ntawv.ino kuv muab.

Kev piav qhia ntawm txoj cai:

Peb pib nrog kev teeb tsa. Hauv kev teeb tsa muaj ob peb kab. Serial.begin (9600) yog teeb tsa kev sib txuas lus nrawm. Hauv qhov no nws tau teeb tsa rau 9600 ntsis ib ob. pinMode (buttonPin, INPUT) teeb tus pin rau khawm. Ntawm ob kab tom ntej koj yuav pom servo.attach (5) thiab servoLock.attach (9). Cov no yog cov pins qhov twg servo tau txuas rau, hauv qhov no servos tau txuas rau 5 thiab tus pin 9. Thaum kawg koj yuav pom resetCatapult (), qhov no hu rau resetCatapult muaj nuj nqi.

Yog tias peb mus rau lub voj koj yuav pom buttonState = digitalRead (buttonPin). Qhov no nyeem lub xeev ntawm lub pob (khawm nias lossis tsis). Yog tias lub pob raug nias lub catapult yuav tua hluav taws thiab rov pib ua kom rov tua tau dua.

Kev ua haujlwm tua kom ntseeg tau tias muaj kev nruj nruj siv rau txoj hlua roj hmab Tom qab qhov no, lub xauv servo qhib thiab lub catapult yuav tua.

Kev rov pib ua haujlwm yuav siv txhua qhov kev nruj tawm ntawm cov hlua roj hmab, ua rau caj npab poob qis. Tom qab qhov no, lub xauv servo xauv lub caj npab thiab lub catapult tau npaj kom raug rho tawm haujlwm dua.

Nrog kev paub txog txoj cai ua haujlwm li cas tam sim no koj tuaj yeem hloov kho txhua yam rau koj nyiam.

Tshaj tawm cov cai rau Arduino.

Kauj ruam 6: Casing

Rau lub casing peb yuav siv 3mm plywood. Kuv txiav tawm 5 daim nrog qhov ntev hauv qab no:

  • 8 x 6 cm (1 daim)
  • 8x5.4 cm (1 daim)
  • 6 x 12.7 cm (2 daim)
  • 8 x 13 cm (1 daim)

Laum ib lub qhov nyob hauv plawv ntawm 8x6 thiab 8x5.4 thooj (xyuas kom nws loj txaus rau 3 xov hlau ntawm qhov kev pabcuam). Laum lub qhov 1.1 cm hauv daim ntawm 8x13 cm raws li qhia hauv daim duab.

Daim ntawv 8x13 cm yuav yog sab saum toj, lwm daim yog ob sab. Siv rab phom nplaum thiab nplaum txhua daim ua ke los ua ib lub thawv.

Kauj Ruam 7: Ua tiav Catapult

Koj yuav luag tiav! tsuas yog ib qib ntxiv thiab koj tuaj yeem txaus siab rau koj cov khoom ua si hauv tsev!

Muab txhua yam tso rau hauv lub casing, tab sis xyuas kom tseeb tias cov servos thiab lub hwj chim cable nyob sab nraud. Kaw lub pob rau lub qhov nyob saum lub casing thiab koj yuav luag tiav!

Tig lub casing kom tau lub ntsej muag sab saum toj rau koj thiab lo cov servo uas tau siv los tua cov catapult mus rau ib sab (tsis muaj teeb meem sab twg). Nco ntsoov tias servo muaj lub kaum sab xis 0 ° thiab taw tes rau ntawm lub npov zoo li hauv daim duab.

Siv lwm qhov ib nrab ntawm daim ntawv ntawv (los ntawm kauj ruam 3), siv cov cuab yeej khoov nws mus rau lub kaum sab xis ntawm yuav luag 180 degrees thiab txiav nws ib nrab ntxiv. Lob cov ntawv khoov thiab ruaj ntseg cov hlua roj hmab ntawm lub catapult rau sab caj npab servo.

Kua nplaum lub hauv paus ntawm catapult rau saum. Nco ntsoov tias tsis muaj qhov nro ntawm cov roj hmab! Thaum kawg lo lub xauv servo mus rau lwm sab ntawm lub casing. Nco ntsoov tias servo muaj lub kaum sab xis ntawm 180 ° thiab thaiv lub caj npab ntawm catapult.

Txhawm rau kom ntseeg tau tias caj npab yuav thim rov qab peb yuav muab daim kab xev tso rau ntawm lub hauv paus ntawm catapult. Thaum caj npab tsoo daim kab xev nws yuav thim rov qab mus rau nws txoj haujlwm qub thiab koj yuav tuaj yeem rov tua dua. Thaum kawg koj ua tiav! Wb sim nws!
