Yuav ua li cas kom txo tau cov load ntawm lub cev
1. So kom nruj nruj dua
Siv txoj hlua khis no dhau lawm, uas ua rau lub cev muaj zog thiab txoj kev txhuam ntawm lub log. Txoj kev ceev nruj pab kom lub cav khiav kom zoo thiab nrog qhov tseeb ntawm qhov chaw.
2. Txo qhov hnyav ntawm lub cav
Lub khob ntawm lub luam tawm platform, lub hauv paus ntawm lub chaw nres tsheb (qee cov tib neeg siv cov hlau), yog qhov chaw ntawm Y-axis thauj khoom hnyav. Cov nyhav nyhav dua yuav ua kom tiav los ntawm kev siv thawm iav lossis los ntawm kev siv thawj lub iav nrog lub rooj fiberglass. Nyob rau hauv lub hauv paus ntawm lub zog txaus, hauv qab ntawm lub luam ntawv yuav tsum tau hollowed tawm ntau li ntau tau, los yog cov khoom sib dua yuav siv tau los txo cov load ntawm lub Y-axis lub cev.
Qhov siab tshaj plaws ntawm qhov X-axis los ntawm lub tshuab tsav tawm. Yog hais tias txoj kev siv lub tshuab extrusion hloov mus rau qhov chaw pub mis Bowden, qhov load ntawm X-axis lub cev muaj peev xwm ua kom zoo heev.
3. Txo cov ntawv luam tawm
Thaum lub tsheb qeeb qeeb, lub hwj huam xav tau tsawg dua. Qhov no tsis tas yuav piav ntxiv dua ~
4. Txo qhov acceleration
Qhov no yog qhov zoo tshaj plaws thiab pheej yig kua uas sau tau sai sai thiab tsis tshee.
Newton cov lus tsa suab ntawm theorem hais F (force) = M (pawg) xa (acceleration)
Raws li qhov kev tsuj zuj zus, cov quab yuam yuav tsum tau raug txo. Txawm hais tias kev txo qis qis kuj pab tau, qhov kev txo feem ntau ntawm kev txo yog tsawg. Txo qhov kev ua kom acceleration zoo tuaj yeem ua kom zoo-tawm-kauj ruam, tab sis nws tsis txhais tau hais tias "qhov sau siab tshaj plaws" yuav txo. Nws tsuas yog siv sij hawm mus ceev rau qhov siab tshaj plaws. Yog li no, txo cov acceleration, tab sis tsis txo tus ceev ceev, tseem tseem ceev ceev ceev printing. Cia li txi ib co sij hawm luam, tab sis txhob plam koj kauj ruam, tua ob lub noog!
Cov nqis nqis, nws pom zoo kom hloov cov tsis nyob rau hauv Marlin firmware ncaj qha los ntawm LCD, thiab tom qab ntawd mam khaws cia rau hauv EEPROM. Koj kuj tuaj yeem hloov ncaj qha rau Marlin Configuration.h cov ntaub ntawv thiab rov muab hliv rau lub 2560 tswj lub rooj tsavxwm. Txwv tsis pub, nws tuaj yeem teev nyob rau hauv daim nplaub tshev software.
Marlin lub chaw acceleration tau muab faib ua ob ntu: Default thiab Max. Vim yog qhov siv acceleration thaum Gcode executes "txav hais kom ua" xws li G0, G1, thiab lwm yam. Lub neej ntawd tus nqi yog 3000mm / s2. Thaum Gcode executes M204 thiab sim hloov cov kev kub ceev, tus nqi teev tsis tau tshaj tus nqi ntawm Max. Acceleration. Ncaj qeeb tso Max acceleration rau 3000mm / s2 los yog tsawg dua los tiv thaiv cov M204 hauv Gcode los ntawm kev nce lub acceleration.
Max. Acceleration tuaj yeem hloov kho los ntawm kev xaiv "Control-> Motion-> Amaxx" thiab "Control-> Motion-> Amaxy" hauv lub vaj huam sib luag hauv LCD. Tom qab hloov kho, nco ntsoov siv "Control-> Storememory" los khaws cov chaw hauv EEPROM. Koj tsis tas yuav rov kho dua nws tom qab khau raj tom ntej.
