I got a problem like a4988 stepper..., with my new a4988.
WOW! I couldn't find these from manufacture sites. Could say what is the current of the motor?
I'm trying, unforunate that the info is so limited.Can you ,measure the resistance of the windings of the stepper?Thanks.. Tom...
I'm not going to read 3 pages of posts to see what you are talking about. Please just describe exactly what you did (with wiring diagrams) and tell us what your current problem is.The Pololu a4988 web page has great information about using the A4988.Read first. Experiment second....R
Sorry, i couldn't draw it in Proteus.
Pencil and paper is fine. Then post a photo of the drawing.It is too easy to misunderstand verbal descriptions of wiring connections....R
I Think the board is fired! I will buy another. Which screwdriver is proper to adjust this potentiometer?
That's a nice drawing and it looks correct. The code in Reply #20 is nearly right. The problem is that you are sending your pulses to the direction pin. And you have no control on the step pin. You need to set the direction pin HIGH or LOW and then send pulses to the step pin.Try the code in my link in Reply #10. But make sure the pin references are correct for your wiring....R
