I am a user who bought a license for a raspberry pie, and would like to run a stepping motor through raspberry pie.

I have questions about how to use a stepping motor using the 'oscat library'.

I want to drive the stepping motor without using the field bus.

I found that oscat library has pwm_dc and pwm_pw, so I tried using this library.

However, the stepping motor turns around without turning smoothly. The input data F and PW or DC values ​​were the same.

Is there any other way to implement a stepping motor?

And can you tell me how to drive a stepping motor using Raspberry Pie and Arduino?

If I have to use EtherCats, I want to know which products I should use and how I can drive stepping motors.

I'll wait for a good reply. Thanks.
