Two stepper simultaneously

[christhebiss]

Hi,
I am working on my art installation, which is driven by two steppers and an arduino uno.
As well there is a button and a switch for homing the motors.
The construction controls a magnetwheel, which moves downwards and upwards.
Attached you will find a picture, the final code and the schematic with the electronics.
I think there I produced a mistake.

Now the problem is, that there is no more electricity at all on the steppers. I think I connected these wrong on the breadboard or with the arduino. Also I destroyed 4 tmc2208 drivers, I think with to much electrictiy from the power supply.

Could anybody help me to solve this problem and maby writing the code a bit more effective.

Thanks in Advance

Chris

I'm surprised you have not also burned out the UNO.
The stepper motors need a separate power supply.
You cannot power motors from an UNO 5v output.

How much current do your steppers require?

[christhebiss]

Hi,
Thanks for your reply.

They are already connected to the 5V Arduino Uno. The seperate Power supply delivers 12V to the steppers. And yes, I burned already a UNO board.
I think I do not connect them correctly to the breadboard. I think they should be all on the same side of the breadboard? But last time I tried to do so, I burned the Arduino...

[jim-p]

First, you should not use a breadboard for motors. The breadboards cannot handle the high currents.
Second, you must determine the current required by your steppers and adjust the driver accordingly.
Third, you need a power supply that can supply the required current for the motors.

Breadboard current limit

Often we tell newbies not to power motors and other high current devices through breadboard because it cannot carry the necessary current. The damage in the photo wasn't caused by a motor, it was caused by an accidental short I didn't notice until I smelled burning, but I think it illustrates the point. [PXL_20241222_085937499] Oh! Why Bar Sport? So you can all have a laugh at my expense! Comments welcome

[jim-p]

Depending on you motor requirements you should consider one of these drivers
https://www.omc-stepperonline.com/stepper-motor-driver

[christhebiss]

What should I use instead of a breadboard for the motors?
And how do I connect in relation to my schematic the other components to each other and the arduino uno?
Could you please give a feedback to my schematic?

I have two Nema-17, the external power of 9-12V should be enough for them, right? I did it like the guy in this video: https://www.youtube.com/watch?v=7spK_BkMJys, basically I installed the whole thing as he suggested...

Is the following power supply a proper solution?:

Thanks for your support!

[jim-p]

@christhebiss

What should I use instead of a breadboard for the motors?

The drivers I suggested have screw terminals for wire connections, so no breadboard is needed.

Is the following power supply a proper solution?

Probably not but as I already mentioned you need to find out the power requirements of your motors. Then you can select the appropriate power supply

[christhebiss]

Yes I saw that on the picture.
There is a recommended current of 12-24V, so I think the power supply on the pic could be possible..?

So as far as I got it right: I buy two of these drivers you recommend (for each stepper one, right?) and connect them directly to the arduino uno? Is for this project an arduino mega better?
Where do I connect the button and the switch?

[jim-p]

@christhebiss

There is a recommended current of 12-24V, so I think the power supply on the pic could be possible..?

Don't buy anything until we get this straight. 12-24V is the voltage, we need to know the current which is in Amps (A) not V
I think it best if you post the data sheet for the steppers you have. So we can see.

[christhebiss]

NEMA17-06_Datasheet.pdf

Here the sheet…

[jim-p]

Thank you. Let me review.

[jim-p]

Two of these will be your best solution for the drivers.
They are rugged, won't get hot and are more tolerant to over currents.
https://www.omc-stepperonline.com/digital-stepper-driver-1-0-4-2a-20-50vdc-for-nema-17-23-24-stepper-motor-dm542t

They are model DM542T, you may find them cheaper at other places.

Now you need a 24V 4A or 5A power supply. Just find one in you price range. It will connect to both drivers. If the motors are located far from the drivers and power supply then you will need some 16 gauge wire to make the connections.

[jim-p]

@christhebiss

Where do I connect the button and the switch?

I show them connedted to pins 2 and 3 but you can use any pins.

[christhebiss]

Thank you very much for your help!
So I connect the two steppers to each driver, then to the arduino and separately the switch and button as you showed?
The power supply is connected to the drivers?
Is that correct?

What you think about the code. Could you make more effective? Now I think its akward, isnt it?

[jim-p]

@christhebiss

So I connect the two steppers to each driver, then to the arduino and separately the switch and button as you showed?

Is that correct?

Yes to all three questions. See page 4 of the DM542 manual on how to connect. Use the common-anode connection scheme.

What you think about the code. Could you make more effective?

Why don't you wait and see if that code even works and does what you want. No point in optimizing code of it doesn't do what you want.

You may want to play around with the code to get art to work the way you want.

[christhebiss]

Thank you so much! Now Im trying to set all this things.
Could you maby recommend a proper power supply for the DM542?

maby this:

TOBWOLF DC 24V 5A Netzteil, 120W AC 100-240V zu DC 24V Netzteil Transformatoren,...

[jim-p]

I'm located in the US, so what I might recommend might not be available to you, might be out of your price range, or may have extremely high shipping costs. It best that you search for yourself. However, I only use power supplies made by MeanWell. They are good quality, you can download the datasheets from the meanwell site and I never had any problems.

The one you selected should be OK but I can't vouch for the quality. Note that it claims to be UL certified but there is no UL mark on the product. Also, the label says " for use with information technology equipment only". Does that mean it is not suitable for motors? Who knows?

Consider one of these:
The second one is cheaper and you need to buy a power cord for it.

MEAN WELL GST40A12-P1J SNT EXTERN 40W 12 : Amazon.de: Computer & Zubehör

MeanWell LRS-150-24 156W 24V 6,5A Industrielles Netzteil : Amazon.de: Gewerbe,...

[MicroBahner]

The second one is an industrial device intended for professionals only. It must not be used by electrical amateurs. (I know that many people use it anyway, but this is not ok and could be dangerous. It should not be recommended - especially in europe with 230V mains voltage).

[christhebiss]

Ok, thanks for your reply, could you recommend one for my installation?

[jim-p]

Does it have to be available in Germany or can it be anywhere in the world.
I only chose those available on Amazon.de
