I am new to 3D printing, so please forgive my ignorance.
I am planning to buy DuetWiFi so that I can connect a 12v 15W 450nm TTL controlled laster module. The answer to this exact question is what I am looking for.
@flippnswitchez, Were you able to make it work? If yes, would you please share your circuit schematics? It would be really helpful to know what needs to be connected where.
