Motor Stepper Example

[aratti]

Check out all the labels in your code! You have names that you never call. Example:

goto close1 your goto will never goto label close1, since you have named it close1(reverse gripper stepper):.

Either move the : to the correct place and rem the rest of the label or place the correct name under the goto instruction.

Close1: ' (reverse gripper stepper)

GOTO Close1


or

close1(reverse gripper stepper):

GOTO close1(reverse gripper stepper)


Timing is not that critical. If too long your motor will run slowly if time delay is too short your motor will not run at all.

thank you for your help..i will try your suggestions...the label close1(reverse gripper stepper) , i only edit it before i post the program so that to clarify the operation of my project..actually is only close1:

If it still does not work after you clean up your code. You may just have one of your coils reversed on your stepper motor. This will cause the motor hum and not rotate. A schematic of your project would help.
good luck

what's wrong when i on my circuit..the led i used as indicator for the sequence will only standby on the first step..and when i touch the positive side of the supply it start to run..i construct my circuit in the breadboard as of now for trial...

..and when i touch the positive side of the supply it start to run

Did you pulled up with a 10K the MCLR (reset pin) of your microcontroller?

Why don't you post your circuit?

i didnt use the MCLR in my mcu...

what is the right thing to do?

You might be able to turn MCLR off but we do not know the chip you are using.
Post your configs, complete code, and schematic so the folks here will be able to help you.
