Thread: Still no go on stepper

Hi,

I'm not familiar with what you're trying to do but a stepper motor works by moving the tiniest fraction or step for each distinct input it recieves, what this means is if you are just running your power supply into it constantly it will move 1 step and stop. To get it to spin continously you need to vary the input voltage as that tells it when to take the next step. you can potentially do this manually by just tapping your positive terminal with the wire from the battery but I don't know what your microstep driver does so I can't gaurentee this will work.

You still need a modulated signal input to the other terminal strip on the motor driver. Someone - I can't recall who - showed this in the other thread. Even linked to what I thought was a pretty good one.

You have a HY-DIV268N-5A stepper driver (TB6600) - I have one ordered. Expected it today but maybe Monday. It needs to be supplied with a pulse (pulse width modulated) signal, as NCArcher said. It drives the Step Port on the driver to Logic High then Logic Low, repeatedly, to cause the stepper to rotate.
Mine will be driven by an Arduino UNO board but I will be trying a $5 NE555 pulse generator as a trial as I want a portable unit.
Can you link to the wiring diagram you used?

If your post is aimed at me, name one, I've tried it, all day there are dozens on the web. I was in the workshop swapping wires and trying all day today.. I'm about to order the $5 one you mentioned, but this looks like it going to be an expensive way to do it, buy and try!

All I asked for was a link to the wiring diagram you used so I could have a look
It not really expensive- the YouTube video I put on the other thread has parts (including the stepper motor) costing a grand total of $22. To add the cost of the driver your using would only cost another $16 and I could subtract the $9 for the other driver. So, under $30.

Geez mate I looked at dozens, can't remember any links but they are all over the web all you have to do is look. Doesn't matter though, everybody apears to be as clueless as me.

Not clueless mate, mine works. We are just trying to help hence I built mine tonight and posted the videos. The key is the pulse signal.

As my reply on your other thread sacc51, to driver a stepper motor, you need a driver and a controller.
'The links I posted earlier were for a controller and for the driver as you will need both (unless you have an external controller: pc with the correct software and parallel port or a circuit board with pulse & direction outputs)'
I understand the learning curve can be frustrating, but remember the people here are trying to help.

I did what you are trying to do a few years ago.As the guys have said, you will need to make an astable oscillator where you can vary the frequency via a potentiometer. I used a 555 timer.What sort of rpm are you looking for? ( if I have missed this in a previous post, I apolagise. )Steve

Sorry, no help here, I've given up.

So sorry we all wasted your time and gave no help. How selfish of us.
Lappa can you post a link to your build. I've been playing with 555s lately and I'm always keen to learn. Although, I googled how to set up a particular application and found a fully functional module that did exactly what I wanted for $1.62 on eBay. No need to reinvent the wheel

The NE555 pulse generators are so cheap to buy on eBay, it’s a waste of time building your own like I used to do years ago. The units on eBay have adjustable frequency from 1Hz up to 200kHz and adjustable duty cycle or PWM. It has a tiny footprint.
I presume you want the link to my stepper motor circuit build? If it’s for the NE555 circuit, I can figure the one out on the board I bought as it’s a little different to many of the diagrams on the WEB due to its flexibility.
My stepper build is a modification to a build on the WEB, as I have introduced a pulse generator rather than a momentary switch which only allows you to step once every time you close the switch.
Let me know which one your after.
Cheers - Peter

A link to your stepper build but a link to the pulse generator you bought would be good too.

They are measured in ma, not much good for a 2 amp stepper! I haven't been able to find a single one that will handle the load.
