Hello,
I am currently trying to develop a Labview VI, that can control two Nema 17 Stepper Motors with a CNC-Shield and A4988 Drivers. It should be very basic (input steps for each motor, speed and direction; thats it). I am currently using a popular example VI which I have uploaded. It works fine, however I do not know, how to change the direction and the stepper number selection does not work for me: if i select Motor 1, it runs fine. If I select motor 2-8, both motors will turn but only roughly a quarter of the selected steps. Also, if I select motor 1 after selecting another number, it will turn in the other direction. This is probably because the program is built for a different driver.
Does anyone know about a good example VI, that can do what I am trying to do? Or can anyone give me advise, how to change the program I am currently using? I am very new to Labview so I hope my problem is clear.
Thank you,
Patrick

Hi pmaxd, I have similar problems with the example, have you yet figured it out?
