      Hi, 
I've encounter some problem on using the stepper motor with my self-built 
driver.  I am not using the driver in the HB. I have to build out a driver. 
The driver chip I use is L298 and logic gate chip is L297 or 374( this chip 
also use in HB) . When I connect the motor to it, there is vibration inside 
the motor. However, the shaft of the motor is not turning at all. I suspect 
that the step sequence is not correct. As a result. I found out that all 
the step sequence are the same  for every clock pulse . According to the 
theory, there should be a 4 step sequece with each sequence is being delay. 
 
 
How should rectify this problem in order to cause the shaft of the motor to 
rotate ? 
Is it my input is incorrect ? 
 
rgds, 
phillip

  |  Hi Philip, are you shure, you have the right pins from the stepper to the outgoing pins from your chip. Have your stepper 4,5 or 6 cables? If you exchange the cables, your stepper motor only do some vibrations or doing nothing. The easiest way to (...)   (27 years ago, 27-Aug-98, to lugnet.robotics.handyboard)
