Pavel Jelic Papita nthawi kuchokera pamene tinakubweretserani gawo lachitatu la mndandanda wa Getting Starting with Engraving. M'magawo apitawo, tidawonetsa limodzi komwe ndi momwe mungayitanitsa engraver ndipo chomaliza, mutha kuwerenga za momwe mungapangire makina ojambulira molondola. Ngati mwadutsa magawo atatuwa ndikusankha kugula makina ojambulira, mwina muli nawo kale atasonkhanitsidwa bwino ndikugwira ntchito pakadali pano. M'gawo lamasiku ano, tiwona pamodzi momwe pulogalamuyo imapangidwira kuwongolera chojambulacho imagwirira ntchito komanso pazoyambira zake. Choncho tiyeni tiwongolere mfundoyo.
Izo zikhoza kukhala chidwi inu
LaserGRBL kapena LightBurn
Ena a inu simungamvetse bwino za pulogalamu yomwe wojambulayo angawongoleredwe. Pali ochepa mwamapulogalamuwa omwe alipo, komabe kwa ojambula ambiri ofanana ndi ORTUR Laser Master 2, mudzalimbikitsidwa kugwiritsa ntchito kwaulere. LaserGRBL. Izi ndizosavuta kwambiri, zowoneka bwino ndipo mutha kuthana ndi chilichonse chomwe mungafune momwemo. Kuphatikiza pa LaserGRBL, ogwiritsa ntchito amatamandanso wina ndi mnzake LightBurn. Imapezeka kwaulere kwa mwezi woyamba, pambuyo pake muyenera kulipira. Ine pandekha ndinayesa ntchito zonsezi kwa nthawi yaitali ndipo ine ndikhoza kunena ndekha kuti LaserGRBL ndithudi inali yabwino kwambiri kwa ine. Poyerekeza ndi LightBurn, ndiyosavuta kugwiritsa ntchito ndipo magwiridwe antchito apamwamba amathamanga kwambiri.
Mutha kugula zojambula za ORTUR pano
Zithunzi
M'malingaliro anga, LightBurn idapangidwira makamaka ogwiritsa ntchito akatswiri omwe amafunikira zida zovuta kuti agwire ntchito ndi chojambula. Ndakhala ndikuyesera kuti ndizindikire LightBurn kwa masiku angapo, koma pafupifupi nthawi iliyonse yomwe ndimakhala ndi mphindi makumi angapo ndikuyesa kuyimitsa mokwiya, kuyatsa LaserGRBL, ndipo imangogwira ntchitoyo mwachidwi. nkhani ya masekondi. Chifukwa cha izi, mu ntchitoyi tingoyang'ana pa pulogalamu ya LaserGRBL, yomwe ingagwirizane ndi ogwiritsa ntchito ambiri, ndipo mudzakhala nayo mabwenzi mwachangu, makamaka mukawerenga nkhaniyi. Kuyika LaserGRBL ndikofanana ndendende ndi zina zonse. Mumatsitsa fayilo yokhazikitsa, kuyiyika, kenako ingoyambitsa LaserGRBL pogwiritsa ntchito njira yachidule yapakompyuta. Dziwani kuti LaserGRBL imapezeka pa Windows yokha.
Mutha kutsitsa LaserGRBL kwaulere patsamba la wopanga
Kuthamanga koyamba kwa LaserGRBL
Mukangoyambitsa pulogalamu ya LaserGRBL, zenera laling'ono lidzawonekera. Nditha kunena koyambirira kuti LaserGRBL ikupezeka ku Czech - kuti musinthe chilankhulo, dinani Chiyankhulo chapamwamba pazenera ndikusankha njira yaku Czech. Mukasintha chilankhulo, tcherani khutu ku mabatani amitundu yonse, omwe poyang'ana koyamba ndi ochuluka kwambiri. Kuti muwonetsetse kuti mabatani awa ndi osakwanira, wopanga chojambula (kwa ine, ORTUR) akuphatikizapo fayilo yapadera pa disk, yomwe ili ndi mabatani owonjezera kuti akuthandizeni ndi ntchito yoyenera ya chojambula. Ngati simulowetsa mabataniwa mu pulogalamuyi, zidzakhala zovuta kwambiri komanso zosatheka kuti muwongolere chojambulacho. Mumalowetsa mabataniwo popanga fayilo kuchokera pa CD yomwe dzina lake limafanana ndi mawu mabatani. Mukapeza fayiloyi (nthawi zambiri imakhala fayilo ya RAR kapena ZIP), mu LaserGRBL, dinani kumanja kumunsi kumanja pafupi ndi mabatani omwe alipo pamalo opanda kanthu ndikusankha Onjezani batani lazosankha kuchokera pamenyu. Kenako zenera lidzatsegulidwa momwe mungaloze pulogalamuyo ku fayilo yokonzekera batani, ndiyeno tsimikizirani kuitanitsa. Tsopano mutha kuyamba kuwongolera chojambula chanu.
Kuwongolera pulogalamu ya LaserGRBL
Pambuyo kusintha chinenero ndi kuitanitsa kulamulira mabatani, mukhoza kuyamba kulamulira chosema. Koma ngakhale izi zisanachitike, muyenera kudziwa zomwe mabatani omwewo amatanthauza ndikuchita. Chifukwa chake tiyeni tiyambire pakona yakumanzere yakumanzere, komwe kuli mabatani angapo ofunikira. Menyu yomwe ili pafupi ndi mawu COM imagwiritsidwa ntchito posankha doko lomwe chojambuliracho chimalumikizidwa - pangani kusintha kokha ngati muli ndi zolemba zingapo zolumikizidwa. Kupanda kutero, kusankha kokha kumachitika, monga momwe zinalili ndi Baud pafupi nayo. batani lofunika ndiye lili kumanja kwa Baud menyu. Ili ndi batani la pulagi yokhala ndi kung'anima, yomwe imagwiritsidwa ntchito kulumikiza chojambula ku kompyuta. Pongoganiza kuti muli ndi chojambula cholumikizidwa ndi USB ndi mains, chiyenera kulumikizana. Nthawi zina, m'pofunika kukhazikitsa madalaivala pambuyo kugwirizana koyamba - mukhoza kuwapeza kachiwiri pa chimbale chatsekedwa. M'munsimu ndiye Fayilo batani kutsegula fano mukufuna kulemba, Kupita patsogolo pambuyo anayamba chosema Inde limasonyeza patsogolo.

Pansipa pali kutonthoza komwe mungayang'anire ntchito zonse zomwe zimaperekedwa kwa wojambula, kapena zolakwika zosiyanasiyana ndi zina zokhudzana ndi chojambula zingawoneke apa. Pansi kumanzere, pali mabatani omwe mungasunthire chojambula pa X ndi Y axis Kumanzere, mukhoza kukhazikitsa liwiro la kusintha, kumanja, ndiye chiwerengero cha "minda" ya kusintha. Pali chithunzi cha nyumba pakati, chifukwa chomwe laser imasunthira kumalo oyambira.
Amalamulira pansi pa zenera
Ngati mwalowetsa mabatani molondola pogwiritsa ntchito njira yomwe ili pamwambapa, ndiye kuti m'munsi mwa zenera pali mabatani angapo omwe amapangidwira kuwongolera laser ndikuyika machitidwe a chojambula. Tiyeni tiphwanye mabatani onsewa limodzi ndi limodzi, kuyambira kumanzere kumene. Batani lokhala ndi kung'anima limagwiritsidwa ntchito kukonzanso gawolo, nyumba yokhala ndi galasi lokulitsa imagwiritsidwa ntchito kusuntha laser pamalo oyambira, mwachitsanzo, kumagwirizanitsa 0:0. Chokhocho chimagwiritsidwa ntchito kumasula kapena kutseka chowongolera chotsatira kumanja - kuti, mwachitsanzo, musakanize batani lowongolera mwangozi pomwe simukufuna. Batani lapadziko lonse lapansi limagwiritsidwa ntchito kukhazikitsa zolumikizira zatsopano, chithunzi cha laser kenako chimayatsa kapena kuzimitsa. Zithunzi zitatu zooneka ngati dzuŵa zimene zili kumanja zimasonyeza mmene mtengowo ungakhalire wolimba, kuyambira wofooka kwambiri mpaka wamphamvu kwambiri. Batani lina lokhala ndi mapu ndi chizindikiro cha ma bookmark chimagwiritsidwa ntchito kuyika malire, chizindikiro cha amayi kenako chikuwonetsa zoikamo za engraver mu console. Mabatani ena asanu ndi limodzi kumanja amagwiritsidwa ntchito kusuntha laser mwachangu kumalo omwe mabataniwo akuyimira (ndiko kuti, kumunsi kumanja, kumanzere kumanzere, ngodya yakumanja, kumanzere chakumtunda ndi kumtunda, pansi, kumanzere. kapena kumanja). Batani la ndodo kumanja limagwiritsidwa ntchito kuyimitsa pulogalamuyo, batani lamanja kuti lisinthidwe.
Pomaliza
Mu gawo lachinayi ili, tayang'ana limodzi zowunikira pakuwongolera pulogalamu ya LaserGRBL. Mu gawo lotsatira, tiwona momwe mungatulutsire chithunzi chomwe mukufuna kulemba mu LaserGRBL. Kuonjezera apo, tidzasonyeza mkonzi wa chithunzichi, chomwe mungathe kuyika maonekedwe a malo ojambulidwa, tidzafotokozeranso magawo ena ofunikira okhudzana ndi zojambulazo. Ngati muli ndi mafunso, musaope kufunsa mu ndemanga, kapena nditumizireni imelo. Ngati ndikudziwa, ndidzakhala wokondwa kuyankha mafunso anu.
Mutha kugula zojambula za ORTUR pano
Moni. Zimamveka bwino, makamaka kwa ine, yemwe ndili ndi chojambula chofananacho. Ndikufuna kudula mapepala mpaka 1 mm wandiweyani nawo. Ndikukhulupirira kuti mudzayang'ananso momwe mungakwaniritsire kuti kukula kwake kumagwirizana ndi choyambirira. Mwachitsanzo Ndinayika m'lifupi mwa chithunzicho kukhala 30 mm (ndiko kuti, ngati kukula kwa pulogalamuyo pansi pa nambala 30 kumatanthauza mm), komabe, zotsatira zake zinali 25 mm. Sakanatha kupanga bwalo nkomwe ndipo zolembazo zinali zopanda pake. Kodi ndiphunzira za zinthu izi apa? Zikomo
Moni, kwa ine kukula kwake kumafanana ndi kukula kwake - kotero ngati ndiyika m'lifupi mpaka 30 mm ndisanajambule, ndiye kuti chinthucho chimakhala ndi m'lifupi mwake 30 mm. Ndipo ngati simungathe kuwotcha bwino bwalo kudzera muzojambula, ndiye kuti mwasonkhanitsa molakwika - yang'anani gawo lachitatu la mndandanda uwu: https://jablickar.cz/zaciname-s-gravirovanim-sestrojujeme-a-zapiname-gravirovacku-3-dil/
Ndiyenera kuthokoza wolemba masambawa, chifukwa posindikiza bukuli, adandikopa kuti ndigule chojambula. Engraver yogulidwa ku China, yoperekedwa m'masiku 4 (masiku anayi m'mawu). Ndimagula m'masitolo achi China pafupipafupi, ndipo pakadali pano palibe vuto. Ndi zinthu khumi ndi ziwiri zomwe ndidalamula, sizinaperekedwe m'milandu iwiri yokha. Pambuyo pa dandaulo, adabweza ndalamazo nthawi yomweyo. Ndikungopangira. Ndipo zikafika pazojambula izi, ndingalandire malangizo ndi malangizo ochulukirapo.
Moni,
Ndikufuna kufunsa za mphamvu ya laser. Kodi mphamvu zitha kukhazikitsidwa ku 3 intensity mu pulogalamuyo yokha?
Kapena ngati laser ili ndi, mwachitsanzo, mphamvu yayikulu ya 5W, ndiye nditha kusintha mphamvu momwe ndimakonda. Ndimakonda izi nditawonera kanema wa wojambula

Zikomo poyankha
Mutha kusintha mphamvu momwe mukufunira. Makamaka, kuthamanga kwa laser kumayikidwa. Kuthamanga kwapamwamba, mphamvu yotsika.
Laser iyenera kuthandizira kuwongolera mphamvu, apo ayi dinani pa zenera la LaserGRBL pafupi ndi kumanja, pansi pomwe - pomwe kuwongolera mphamvu, kuthamanga ndi kuthamangitsa (S,G1,G0) kuli.
Moni, chonde, ndagula laser kuchokera ku China, imalemba kalilole ndipo sindikudziwa kuti ingakhale chiyani. Ndili ndi pulogalamu yojambula. Ndipo ndikufunanso kufunsa, kodi pali penapake kudula plywood kapena kudulidwa pa liwiro la laser? Sindikupeza kuya kwa kudula. Zikomo chifukwa choyankha Jarda
Kuchokera pazomwe ndakumana nazo - ndimayesa kusinthanitsa zingwe ndi ma mota. Ndinalumikiza ma axis motors molakwika monga choncho ndipo ndinalembanso pagalasi. Zachidziwikire, mutatha kusinthanitsa zingwe, musaiwale kusintha zero (zimadaliranso mtundu wa laser).
Ndilinso ndi vuto ndi njira yosiyana ya mayendedwe. Zingwezo zili ndi malekezero opindika, kotero sizingasinthidwe pokhapokha nditazidula. Ndidayesa kaye mu pulogalamu ya Benbox ndipo idapita komweko. Len ndi wosakhazikika kotero ndimafuna kuyesa GRBL ndipo mwadzidzidzi zimapita kwina. Muli chiyani?
Moni, ndakhazikitsanso madalaivala ndipo zimagona bwino. Ndinayang'ana chithunzicho m'makonzedwe asanayambe kuyaka. Ndipo ponena za kudula, ndili ndi laser yofooka kwambiri, 2,5W, ndipo sindidzaika kupitirira 3mm. m kupita ku 5W mwamsanga momwe ndingathere .kupanda kutero kuya kumatsimikiziridwa ndi liwiro, kapena mphamvu yamoto.
Moni,
Nkhani zabwino kuti muyambe. Ngati muli ndi nthawi, ndikufunika malangizo. Mtundu wa Mi Ortur Master 2 20w wafika. Kulumikizana, kukhazikitsa, chilichonse popanda mavuto. Vuto linachitika posuntha laser motsatira y-axis. Laser imasunthira kumalo omaliza popanda vuto lililonse, koma ikayaka kapena kupanga mapu, m'malo mosunthira mbali imodzi, mkono umayenda motsatira y-axis sitepe imodzi mmbuyo ndi mtsogolo ndikuwotcha mzere umodzi. Ndikasuntha nsonga iyi pogwiritsa ntchito mivi mu LaserGRBL, ndimadina muvi wakumunsi ndipo laser imayenda mwachisawawa mmwamba kapena pansi. Zimakhala ngati akuyamba kusokonezeka. Sindinapeze yankho kulikonse. Cholakwika chomwecho chimapezeka mu LightBurn pa MAC. Ndinakonzanso lamba wa mano, ndikuyesera kusintha chingwe cha USB, kuyang'ana zolumikizira, palibe kusewera kulikonse. Ine ndiri kumapeto.
Moni, ndine watsopano, ndagula makina ojambulira, malangizo amomwe mungawonjezere mabatani sagwira ntchito, sindikudziwa choti ndichite nawo Winawake adagula Rybitví, Pardubic, ndani angandithandize ndi izi? Zikomo
Moni, mupanga liti kutulutsa gawo lotsatira?
Zikomo.
Kutengera ndi mndandanda waukuluwu ndidagulanso Ortur Master 2 15W ndipo ndine wokhutira kwambiri. Inafikadi m'masiku 5! Ndipo izo mu nthawi isanafike Khrisimasi! Ndili ndi funso limodzi - ndimatsitsa kuti mabatani?
Ndinali ndi mafayilo onse ofunikira ndi madalaivala pa CD yomwe idaphatikizidwa. Kupanda kutero mutha kutsitsa zomwe zili mu CD pogwiritsa ntchito ulalowu, awa ndi mafayilo ovomerezeka a wopanga: https://www.dropbox.com/s/1o76v7d1rkqcb2j/LaserMaster2.zip?dl=1
Tsoka ilo, ulalowu sukugwira ntchito, ngakhale chowotcha chimandigwirira ntchito, koma ndikufuna kuwonjezera mabataniwo. Ndiloleni ndikhale nazo.
Kodi pali amene akudziwa ndi Atomstack A5?
tsiku labwino,
Ndili ndi Atomstack A5 Pro kunyumba ndipo ndine wokhutira kwambiri. Ndinagulanso cholumikizira cha rotary chake ndipo makina amandisangalatsa. Ndinagula LightBurn monga SW, ndimagwira ntchito pa Mac (LaserGRBL ndi PC, kukhazikitsa pa Mac kungakhale kovuta, komanso kukanakhala kotheka) ndipo panalibe vuto ndi HW ndi SW - unsembe, kugwirizana, kulankhulana pakati. SW ndi HW,... Ndikusewerabe pang'ono ndi mfundo yakuti zipangizo zosiyanasiyana zimadulidwa / zojambula mosiyana, koma ndayesa kale zoikamo zambiri ndipo zimagwira ntchito. beech - zotsatira zake ndi zodabwitsa. Ndinayesanso chikopa komanso chabwino. imadula pepala bwino kwambiri. kuchokera kumalingaliro anga, ndikhoza kuvomereza izo ndipo ndikuganiza kuti zidzabweretsa chisangalalo chochuluka osati kwa inu nokha, koma ngati mutapereka zotsatira za kusewera kwanu kwa wina, mudzawona chisangalalo.
Moni.
Ndili ndi vuto kulumikiza chojambula kudzera pa chingwe cha USB. Sichikufuna kugwirizana ndi mapulogalamu. Ndayika Driver_CH340SER. Ndatsitsa mtundu wa LaserGRBL 4.3.0
Zikomo pasadakhale malangizo.
Zathetsedwa :-)
lingaliro lomaliza linatuluka:
- kuzimitsa chojambula ndi batani ndikuyatsanso
- kukhazikitsanso ndi batani la RESET pa bolodi lowongolera
Kenako pulogalamuyo idapeza doko lolumikizira (sinali COM1, lomwe silingasinthidwe mpaka pamenepo) ndikulumikizidwa.
Moni, kodi mudakumanapo ndi vuto loti kutumiza kwa svg kuchokera ku Illustrator kumasokonezedwa ndi GRBL ndikusintha sikelo? Chilichonse chimakulitsidwa kangapo kwa ine. Zikomo chifukwa cha malangizo Martin
Moni, Ndikufuna kufunsa ngati wina wakumanapo ndi vuto ngati langa ... Wojambula akugwira ntchito, zonse zili bwino kuphatikizapo laser, ndikungodandaula ndikupukuta nkhwangwa. Mutha kusuntha kuchokera kukona yakumanzere kupita kukona yakumanja yakumanja, i.e. moyang'anizana ndi mnzake, apo ayi wojambulayo sangasunthe, kapena angasunthike kwina kuposa momwe ayenera, kapena "agwedezeka". Kodi alipo angandilangize? Zikomo kwambiri.
Ndinalinso ndi vuto ngati lomweli mpaka ndidazindikira kuti waya wina wopita ku mota adatulutsidwa ndi cholumikizira. Ndiye chabwino.
Kodi pali aliyense amene ali ndi malangizo amomwe mungasinthire mawuwo (GRBL, LightBurn) kuti zilembo zisagwe mukadula makatoni? (O, A, B, ...) mwachitsanzo kuti athe "kuyika" zolumikizira zazing'ono.
tsiku labwino,
Sindinapeze izi mu LightBurn. Ine ndekha ndimasintha zinthu zakunja ndipo nditatha kukonza ndimazilowetsa ndikupitiriza ndi chinthu chosinthidwa. Koma pali font yomwe yakonzeka kale kusankha izi (mwachitsanzo: https://www.ceskefonty.cz/ceske-fonty/vida-stencil-demo - pansipa ulalo ndi chitsanzo chabe cha mawonekedwe)
Moni, pali amene wathetsa vuto ndi kusalondola kwa X axis? Mwanjira ina imadumpha ndi mamilimita angapo panthawi yojambula ndipo zotsatira zake ndi kutayidwa. Malamba ndi zingwe zili bwino.
Vuto lenilenili limandivutitsanso ine. Kodi alipo amene ali ndi yankho?
Ndinali ndi vuto lomwelo. Zinali zokwanira kukhazikitsa zoyambira ndi zotsika muzokonda za GRBL ndipo chilichonse chimayenda momwe chiyenera. Ndiyesera kupeza manambala amenewo penapake...
Moni, kodi alipo amene ali ndi kutsitsa kwa custombuttons.gz komwe mungandipatseko. Wojambula wa Ortur Laser Master Pro S2 adafika popanda CD ndipo ulalo womwe uli patsamba la wopanga sukugwira ntchito
Kodi pali aliyense wodziwa ndi MAC ndi pulogalamu ina kupatula GRBL ndi LightBurn?
Tsiku labwino,
zimandilemba ngati galasi, ndingasinthe bwanji chonde?
Moni, simukudziwa momwe mungakhazikitsire laser? Ndikachita zambiri, mzere wa laser umakhala wolimba kwambiri. Kodi mungalangize? Zikomo
vuto lidzakhala lens lakuda la laser, lomwe silingathenso kuyang'ana (monga magalasi onyansa), utsi woyaka moto umakhazikika pa lens ndipo pakapita nthawi kuwala kwa laser kumabalalika pa dothi ndipo motero njira ya laser pa workpiece ndi yotakata. mphamvu yamtengowo ndi yofooka. Zimathandiza a) kusintha lens la laser ngati kuli kotheka komanso panthawi imodzimodziyo kuwombera ndi mpweya, zomwe zimachotsa utsi wa laser kuti usakhazikike. b) imathetsedwa ndi gawo la laser palokha mothandizidwa ndi chowotcha chozizira (ma lasers ena atsopano komanso amphamvu) kapena chowombera chiyenera kuwonjezeredwa kunja (mapampu a mpweya amagwiritsidwa ntchito pamayiwe, etc.)
