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 (...) (26 years ago, 27-Aug-98, to lugnet.robotics.handyboard)
