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 test the sequence is the following (Stepper Motor with 5 or 6
Cables)
Most steppers with 6 Cables are using 2 for their voltage.
For example
Outgoing Pins form Chip
Step 1)
1 ---------- Stepper in 1
2 ---------- Stepper in 2
3 ---------- Stepper in 3
4 ---------- Stepper in 4
it doesn´t work then go to STEP 2
Step 2)
change Stepper in 1 with Stepper in 4 it doesn´t work go to STEP 3
Step 3)
change Stepper in 2 with Stepper in 3 it doesn´t work go to STEP 4
Step 4)
change Stepper in 3 with Stepper in 4 it doesn´t work you have a big problem
:-)
I have test some steppermotors with an special mini-electronic (NE555 and
Stepper Chip SAA????)
With this equipment i test my Motorpins. It´s very easy and i have the correct
cable sequence.
cu and good luck

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