How to use a 14HM11-0404S1 to create a robotic arm?

[scosn]

hello to everyone,
I recently bought a stepper motor called 14HM11-0404S1 to create a robotic arm. since I am not very experienced in the matter I tried to inform myself and I bought a cnc shield for arduino and also a DRV8825 to put on the board named before. here are the questions I would like help with:

Are the drivers I bought okay?

How many volts and how many milliamps do I need in total to make the robotic arm (I need 6 motors) ? and how many volts and how many milliamps are needed for each motor?

here are the datasheets:

This link does not lead to the expected data sheet. Learn searching for data sheets and avoid the alldatasheet and similar collections.

A real data sheet like this answers your questions about the motor voltage and total motor currents: 0.4x2x6 A.

As an exercise look up a data sheet for the DRV8825.

The CNC shield can handle 4 motors, not 6. You need a different solution for your 6 motors.

Can you show a drawing or a picture of what you think your robotic arm will look like?
