Probleme legare drivere la breakoutboard

Recommended Posts

Va salut din nou .

Masina construita de mine functioneaza perfect in configuratia urmatoare.

Breakoutboard model HY-JKM5 http://www.tecnoflexo.com.br/site/fotos/download/17/17.pdf

Drivere http://www.longs-motor.com/productinfo/detail_12_80_131.aspx

Dar pentru ca pe masina am Nema 17 cu 1,7 A  driverele sunt prea puternice asa incat le-am scos si le-am inlocuit cu modelul http://www.longs-motor.com/productinfo/detail_12_80_148.aspx.

Cum fac legaturile intre modelul din urma si placa ?

Multumesc pentru raspunsuri

Primul driver nu era prea puternic, il puteai seta la o valoare mai mica.Al doilea driver este anod comun. In loc sa ai + individual pentru toate semnalele, ai un singur + comun.

Primul set de drivere (care au fost setate la curentul potrivit)  tebuie sa le folosesc la o masina mai puternica ,asa ca din economie am achizitionat la jumatate de pret fratii  mai mici ,in alte conditii puteam sa mai iau un set de drivere la fel .Am inteles ca am anod comun dar unde introduc acest anod ?DM 420 are doar 4 pozitii de conectare fata de DM 452 care are 6 pozitii din care catodul ocupa 3 pozitii .

Am rezolvat problema in final . Mai simplu decat credeam . De pe interfata se ia doar firul de pulse si step iar din alimentarea de 5v intereseaza doar +care se imparte la fiecare driver

Cam asta ti-am spus in postul #2 si tu ai zis ca ai inteles ce inseamna anod comun.
