ramps 1.4 i motori non girano

Messaggi raccomandati

salve a tutti, ho un urgente bisogno di aiuto,.

ho appena finito di assemblare una prusa i2 totalmente autocostruita, andava tutto liscio fino a quando non ho collegato per la prima volta la scheda al pc, con repetier ho provavo a muovere i motori in manuale ma non giravano, vibravano soltanto, dopo tanti tentativi ho dato il comando di muoversi di 10 ad un motore e questo ha iniziato a girare senza fermarsi e intanto il driver si scaldava piano piano fino a scottare, quindi io ho schiacciato su stop.

tutte le altre volte invece facevano e fanno uno scatto, iniziano a vibrare poi il driver scotta quindi io fermo tutto.

i driver li ho settati ad una vref di 0.4 e i motori sono da 2.5A

Quale può essere il problema?

Sono disperato

ciao! beh sicuramente hai sbagliato a configurare i driver!

questa è una piccola guida su come configurerai driver, http://www.stampa3d-forum.it/guida-rego ... stepstick/

ma attento che gli A4988 possono erogare massimo 2A e con alette di raffreddamento!!! percui se le hai devi fare i calcoli come se il tuo motore sia da 2A altrimenti ancor meno!

facendo due calcoli dovresti avere una vref da 0.6-0.8

ok, comincio a a pensare che sei riuscito a bruciarli! hai scollegato l'alimentazione mentre giravi il potenziometro? sei stato attento a non fare cortocircuiti con il tester?

a quanto hai impostato la velocità massima degli assi nel firmware? sein caso riesci ad allegare il file configuration ?
