Hello.
I want to control a stepper motor with a raspberry pi.
The motor specs are: E Series Nema 34 Stepper Motor Bipolar 1.8deg 4.8 Nm(679.87oz.in) 6.0A 86x86x80mm 4 Wires
Will the Adafruit stepper HAT work for this? If not any suggestions on what will work?
I wanted to use the Raspberry Pi because I have one laying around, but would an audrino work better?
My second step of this project is to make the motor work on voice commands...
Any suggestions?

Re: Stepper motor and raspberry pi
The H-Bridge on the stepper hat can only provide up to 1.2A per channel.
Your stepper requires more current than the Stepper Hat can provide with its 6A rating.
Do you really need to use such a large stepper for your application? I've heard of others using solids state relays to expand the shields ability, but that is expensive and only works on unipolar steppers.

https://www.adafruit.com/product/2348Motors are controlled by TB6612 MOSFET drivers with 1.2A per channel current capability (you can draw up to 3A peak for approx 20ms at a time),

Re: Stepper motor and raspberry pi
Those motor specs are incomplete. You will need to know other details like the phase resistance in order to choose a compatible driver. But it is well beyond what the motor HAT can handle.
www.pololu.com carries a wider range of hobby-grade stepper drivers. But for 6A/phase motors, you will probably need an industrial grade controller such as a DM860. These are available from several sources on-line.

Re: Stepper motor and raspberry pi
Thanks for the replies.
No mikeysklar, I most likely don't need this big motor, but this is the one I got :)
And Bill, thanks for the suggestion. They have some nice controllers that can be used by Arduino, so I would guess also raspberry pi...
I will see if I get a reply from them :)
Thanks again to both.
