Sorry but i’m confused how 2.5 amp driver (DRV8825) drive 2 Nema 17 Stepper Motor Bipolar 2A 84oz.in?
And i have another question i have nema 17 stepper motor with (BLK, GRN , RED , BLU) how can i parallel them to Y axis?
Do i have to connect the BLK of motor 1 to BLK of motor 2 and GRN of motor 1 to GRN of motor 2 and the same with RED and BlustevanParticipantNovember 18, 2015 at 4:23 pmPost count: 3
You can try to follow the connection scheme with the colors of wires in the attached image.

That should help with the wiring.
As for the stepper amps. http://www.vicious1.com/forums/topic/how-to-connect/#post-3461
It breaks down to your steppers are 2Amps at like 3Volts, we run them at 12volts so the amps is lower.
2ampsx3Volts=6watts the more important number is watts.
.5 amps x 2steppers = 1 amp needed from the driver.
Hope that makes sense, I hope I am correct with all this it seems to work out when I set the drivers so I assume I am doing something right.
Clear as mud?vicious1KeymasterNovember 18, 2015 at 4:42 pmPost count: 2669
Of course your amps and volts will be different. That was just an example.Asho777ParticipantNovember 19, 2015 at 3:05 amPost count: 59
Black of motor 1 to Black of motor 2
Green of motor 1 to Green of motor 2
Red of motor 1 to Blue of motor 2
Blue of motor 1 to Red of motor 2
Just an attempt to make it 100% clear, as my motors are the exact same colours!
