Dear Stas,

Thanks.

Many I should work on your datas to solve the interfacing matter.

We will update the page about stepper with the photo how the motor should be wired. As to the commands, I will put this task to our to-do list. That will take a week or two.

I am afraid not having found those ...

Hello Stas,

Thanks for your help.

I found out my arduino board includes a FTDI chip.
Does it will works with HR ?

Kind regards
Pierre
