• Nozzle kub: 200 ° C.
• Lub txaj sov: 60 ° C.

Tsis muaj ntau yam hais txog qhov no tshwj tsis yog, muaj kev lom zem luam ntawv.

Kauj Ruam 5: Sib dhos Qhov (intro)

Zoo tam sim no peb mus txuas ntxiv txhua yam. Ua ntej kuv piav qhia txhua yam nws kuv yuav hla qee yam kom nco ntsoov thiab qhov ntawd yuav pab koj ua tiav qhov no.

TSWV YIM 1:

Kuv tau txiav txim siab ua txhua lub qhov 2.5mm tshwj tsis yog 3mm zoo li cov ntsia hlau. Qhov no yog li koj tuaj yeem coj mus rhaub xov los ntawm kev ntswj rau hauv cov ntsia hlau thiab tshem tawm qhov xav tau ntawm cov txiv ntoo. Tau txais cov ntsia liaj qhov rooj yog qhov nyuaj heev, siv koj cov hlau txuas txhawm rau txhawm rau sab saum toj, qhov no yuav ua rau nws yooj yim kom tau cov ntsia liaj qhov rooj nkag thiab pib ntswj.

TSWV YIM 2:

Yog tias zoo li kuv koj tau ua haujlwm qis ntawm cov ntsia hlau, tsuas yog ntsia hlau hauv kab pheeb ces kaum. Qhov no txuag ntau ntawm lawv thiab ua haujlwm zoo.

Kauj Ruam 6: Sib Sau Sab Saum Toj (Dispenser)

Cov ntu tau tso tawm raws li hauv daim duab.

Lawv tau tuav ua ke los ntawm qhov hu ua 'daim hlau'. Ib daim phiaj sib sau ua ke rau koj lub cav tsav.

Nco ntsoov tias sab saum toj ntawm cov ntsia liaj qhov rooj tau yaug nrog cov nplaim, lwm qhov kev pub mis yuav thaiv. Koj yuav tsum siv 3x8mm ntsia liaj qhov rooj rau qhov no thiab "Stepper_offset" tus qauv nruab nrab ntawm cov stepper thiab sab nrauv ntawm phaj.

Tam sim no muab zeb rau tus stepper, nws yuav tsum mus yooj yim haum. Yog tias tsis yog, koj tuaj yeem siv qee qhov vaseline.

Tus so yog ncaj nraim rau pem hauv ntej, tsuas yog siv tus ntsia hlau uas koj pom lub qhov.

Kauj Ruam 7: Sib Sau Sab Saum (Ntim)

Ntawm no koj pom yuav ua li cas kuv ua kuv lub thawv. Cov kaus poom yog qhov qub siv rau qhuav ntawm kev sib koom ua ke.

Nyob rau saum toj kawg nkaus, koj xav xa daim TOF-sensor, qhov no yuav raug siv los ntsuas seb cov zaub mov muaj nyob hauv lub ntim ntau npaum li cas. Hauv cov duab koj tuaj yeem pom tias kuv txuas nws li cas. Ua ntej kuv yaj lub qhov rau cov pins nrog kuv cov hlau txuas, tom qab ntawd glued lub sensor nyob rau hauv qhov chaw nrog qee cov kua nplaum kub thaum cov kab txuas txuas.

Txog kev kaw lub thawv Kuv tau ua 2 qhov nrog kuv cov hlau txuas thiab ntswj rau hauv 2 lub qhov taub. Ib txoj hlua roj hmab, hlua khi lossis xaim tuaj yeem siv tau los kaw nws li ntawd.

Kauj Ruam 8: Sib dhos Hauv Qab

Rau qhov kev tso kawm ntawm cov qauv sib txawv siv cov duab, lawv zoo nkauj heev piav qhia tus kheej. Ib feem ntawm cov duab no twb tau txuas rau hauv lawv, koj yuav tsum saib yav dhau los tam sim no. Cov duab uas coj mus rau hauv nruab nrab ntawm kev txhim kho txoj haujlwm no. Thaum pib txoj phiaj xwm tau muab tso rau hauv lub xov tooj ntawm tes thiab hnyav cov zaub mov tab sis vim yog kuv lub cell load amp tawg thaum lub sijhawm kawg, kuv yuav tsum tau muab cov khoom ntawd tshem tawm thiab hloov nws nrog cov vis dis aus nyob uas tseem zoo nkauj heev. Qhov kev xaiv ib txwm nyob ntawd txhawm rau ntxiv lub xov tooj ntawm tes, tab sis koj yuav tsum khawb mus rau hauv txoj cai thiab kho qee yam khoom.

Kauj Ruam 9: Khoom siv hluav taws xob, Sensors thiab Actuators

Tam sim no nws yog lub sijhawm los muab cov hlau txuas rau. Kuv tau muab 2 tus sawv cev ntawm yam koj yuav tsum tau ua, ib qho qauv siv hluav taws xob, ib qho kev sawv cev pom. Kuv xav qhia koj siv cov txheej txheem hluav taws xob vim tias nws muab kev nkag siab ntau ntxiv txog yuav ua li cas txhua yam ua haujlwm thiab txuas nrog rau ib leeg hauv kuv lub tswv yim. Qhov laj thawj tsuas yog lwm tus nyob ntawm no, yog vim nws yuav tsum tau ua. Vim li cas kuv hais qhov no, yog vim tias tsis muaj ntau qhov chaw rau cables, yog li koj yuav tsum tau ua kom zoo nrog txuas GND, +5V, thiab lwm yam uas nyob ntawm seb koj xav khiav koj cov cables li cas. Yog li tsis txhob xaim txhua yam raws nraim ib leeg zoo li cov phiaj xwm, nws yuav ua haujlwm tab sis yuav tsis haum.

Txog qhov hloov pauv koj tuaj yeem pom kuv txuas tag nrho 3 ntawm cov coj, qhov no yog vim qhov kev hloov pauv los nrog lub teeb tsa hauv LED uas qhia tau yog tias lub hwj chim tau qhib. 2 qhov tsis muaj xim ua raws li qhov hloov pauv, cov xim coj mus rau GND.

Feem ntau qhov no yog qhov kev txiav txim kuv txuas txhua yam:

1. Fais fab seem: fais fab txuas, h-choj, txhawb nqa tus nqi hloov pauv, hloov pauv
2. Raspberry Pi (Saib cov kauj ruam tom ntej kom paub ntau ntxiv)
3. IR-sensors
4. LED cov
5. Stepper inputs
6. I2C feem: 3.3V, SDA, SCL

Nws tsis yog qhov tseem ceeb tab sis muaj txiaj ntsig kom muaj cov qauv pcb tso ib puag ncig kom zoo li kuv tau ua.

Tsis tas li tsis txhob hnov qab txuas lub koob yees duab mus rau USB chaw nres nkoj ntawm pi.

Tseem ceeb:

Nco ntsoov hloov kho qhov hloov pauv hloov pauv mus rau 5V ua ntej nqes mus rau 5V feem ntawm Circuit Court. Lwm qhov koj tuaj yeem ua rau muaj kev pheej hmoo ntawm kib txhua yam. Txhawm rau kho qhov no koj tig lub hwj chim thiab saib qhov ntsuas hluav taws xob ntawm lub vijtsam.

Kauj ruam 10: Electronics, Raspberry Pi

Vim tias muaj kev txwv nyob hauv software kom kos cov txheej txheem kuv tsis tuaj yeem kos yuav ua li cas txhawm rau sib txuas raspberry pi.

Txog +5V koj tuaj yeem tsuas yog xaim mus rau 5V tus pin ntawm pi, tab sis qhov no hla dhau kev nyab xeeb xws li fuse. Yog tias koj saib hauv qab koj yuav tsum pom qee cov ntaub qhwv uas sau tias yog TPxx, hauv peb qhov xwm txheej peb tab tom nrhiav TP1 lossis TP2. Solder koj +5V cov hlau lead rau ib ntawm lawv tab sis ceev faj tsis txhob txuas nrog lwm cov cim. Qhov no feem ntau tseem yuav void qhov kev lees paub. Kuv tus kheej tau sim nqes nws mus rau ob qho kev ntsuas ntsuas thiab tuaj rau hauv kev suav tias nws yog qhov yooj yim tshaj plaws thiab muaj kev nyab xeeb tshaj plaws los siv TP2, nws nyob deb ntawm lwm cov ntaub qhwv tawm thiab tsis muaj ntau cov kab ib puag ncig nws.

Rau GND tsuas yog siv ib tus pin rau saum zoo li cov phiaj xwm qhia, qhov no zoo kawg nkaus tam sim no.

Kauj Ruam 11: Kuaj Cov Khoom Siv Hluav Taws Xob

Thaum txhua yam txuas nrog kom raug nws yog qhov kev coj ua zoo los sim txhua yam ua ntej sib dhos txhua yam kom tiav.

1) Thaum lub sijhawm sau qhov no, tus pi xav tau kwv yees li 2 feeb txhawm rau khau raj kom tag li koj yuav tsum muab qee lub sijhawm ntxiv.

2) Koj tsis txuas koj lub LCD kom raug. Koj tuaj yeem pom yog tias koj txuas nws raug los ntawm kev ntaus cov lus txib hauv qab no hauv lub plhaub:

sudo i2cdetect -y 1

Qhov no yuav tsum xa 2 qhov chaw nyob: 0x27 (= LCD) thiab 0x29 (= TOF sensor). Yog tias 0x27 tsis tshwm sim koj yuav tsum tau tshuaj xyuas qhov txuas ntawm lub lcd. Yog tias ob qho tib si tsis tshwm sim, koj yuav tsum txheeb xyuas qhov txuas ntawm SDA thiab SCL pins. Piv txwv li xyuas yog tias koj pauv ob qho los ntawm kev sib tsoo. Qhov xwm txheej phem tshaj koj tau ua qee yam tsis raug nrog 2 tus neeg ib feem lossis qee yam tawg.

- Kuv lub LCD tau daig ntawm "Txuas rau WiFi"

Qhov no txhais tau tias koj tus pi tau nyam sim txuas mus rau ib qho ntawm cov tes hauj lwm uas koj tau teeb tsa los txuas rau. Qhov no txhais tau tias koj tsis nyob hauv thaj tsam ntawm qhov chaw nkag lossis koj tau ua qee yam tsis raug thaum teeb tsa piv txwv ib typo. Hauv qhov no rov qab mus rau "Teeb WiFi" thiab rov mus dua.

Lub software tseem tau teeb tsa los txuas rau cov tsev sib txuas hauv tsev nrog tus IP chaw nyob uas pib nrog "192.168". Yog tias koj lub network tau teeb tsa nrog lwm qhov ntiag tug xws li "10.0" lossis "172.16" koj yuav tsum tau nkag mus rau /home/pi/project/main.py thiab hauv kev ua haujlwm get_ips () hloov pauv: yog "192.168" hauv ip yog "Koj tus kheej ntau ntawm no" hauv ip.

- Kuv lub LCD qhia tus IP tab sis kuv txuas tsis tau:

1) Nco ntsoov tias koj txuas rau 192.168. X. X tus ip, lwm tus ip 169.254.10.1 ib txwm teeb tsa los txuas hla ethernet ncaj qha rau koj lub PC. Qhov no yuav tsis ua haujlwm yog tias koj tsis txuas rau.

2) Nco ntsoov tias koj nyob hauv tib lub network, lossis koj tau qhib chaw nres nkoj xa mus rau ntawm koj lub network yog tias koj xav nkag mus rau tus pub los ntawm sab nraum nws lub network.

- Tus stepper co thiab tsis tig:

Qhov no txhais tau tias koj tsis raug txuas cov tswv yim lossis cov txiaj ntsig ntawm dual H-choj. Sim pauv lawv ib ncig kom txog thaum nws ua haujlwm.

Kauj ruam 12: Ua tiav

Tam sim no koj tau txiav txim siab yuav ua li cas kom txhua yam ua tiav, nws yog lub sijhawm los muab txhua yam ua ke. Kuv yuav tsum muab 2 ntu ua ke nrog daim kab xev, qhov no vim tias qhov tsim ntawm lub qhov tsis ruaj khov txaus los tuav qhov nro thiab nws tawg rau kuv. Nov yog ib qho tseem ceeb uas yuav tsum tau txhim kho yav tom ntej. Qhov kev xaiv ua kom huv yog tsuas yog lo ob daim ua ke tab sis qhov no tuaj yeem muaj teeb meem thaum qee yam sab hauv tawg thiab koj xav kom nkag mus rau sab hauv. Tias yog vim li cas kuv mus nrog daim kab xev hluav taws xob qub zoo.

Thaum koj mus rau lub vev xaib koj yuav tsum tau txais tos nrog lub dashboard uas koj tuaj yeem ua tej yam xws li kev pub zaub mov noj, txheeb xyuas qhov xwm txheej, saib cov ntaub ntawv thiab ntxiv presets.
