Can anyone advice me on the Big Easy Stepper Driver, I don't seem to be getting power to the motor.
I'm not an electronics wizard by any means, just trying to understand enough to accomplish a
project of mine.
The LED is lit on the driver board, in fact when I first applied power to it (12V), it seemed to be
working, counting sounds and the motor getting warm.
I unplugged the power supply, downloaded a demo sketch to my Arduino, plugged the power supply
back in, now nothing.
What do you think this could be?

Thanks

Wait!  I know, I know... I say it's because Mercury is in retrograde.

You might consider showing us your circuit and code.  Otherwise, any speculation on our part is coming from la-la land.  Please use the links to the right to properly add your code to a posting and images to of your circuit.  Make sure we can see which wires are going to which pins.

@banjobrad2

Counting noises ?

If you just yanked the power from the Big Easy while it was running, it may have released the magic smoke. Stepper drivers don't like to be treated that way. If you have an oscilloscope, try monitoring the 4 wires out to the motor to see if the coils are still being triggered.

If they aren't - get another driver board; if they are - follow @Inq's advice and show us what you're doing.

Experience is what you get when you don't get what you want.

@ banjobrad2 fyi @Inq This is one of those 'how deep is the ocean 98.46893 miles due east from the Cape Hatteras lighthouse' type questions. If you can answer that I will answer your question, deal? 🙂

Arduino says and I agree, in general, the const keyword is preferred for defining constants and should be used instead of #define

Actually, that one would be easier...

It's 11437 feet deep relative to where the lighthouse used to be.

It's 11454 feet deep relative to where the lighthouse is today.

Hi @banjobrad2,

   As already mentioned, we can't see your set up, so any suggestions are based on a mixture of guesswork and gut feeling...

I haven't seen this product, but I am guessing your project looks like:

  https://learn.sparkfun.com/tutorials/big-easy-driver-hookup-guide

The Sparkfun guys seem to have a reasonable reputation, so it is probable that if you follow exactly what they say, then it will probably work ... (unless you have accidentally broken something, but luckily elctronic boards survive a lot of maltreatment, although magic smoke is not unknown).

My suggestion is that you carefully follow their instructions to the letter, and see how you get on.

If you have a precise question at some point, then post it and someone may be able to help, providing they know exactly  what you have done and what you can see.

The stepper motor drive board has many signals and jumpers, so there is a lots of ways of 'nearly' wiring it up, but actually leaving it in a state where it does nothing.

I am not a betting person, but if I was, then providing you have followed their instructions, downloaded and installed their demo software, but it still doesn't work, then my first pound/dollar would be on a wiring error, (including the jumpers, etc.).

By the way, another trick if it still doesn't play, if you can persuade someone to help you, even if they are not familiar with electronics and software, is to sit down together and go through every step again, with you explaining what it says to do and how you have done it. It is very difficult to check your own work, as you tend to see the same thing, even when it's wrong.

If you have a meter, use it to check all of your connections.

Good luck, Dave
