Controllino 2 steppers

Hi,

I saw on youtube that controllino can run 2 steppers, i tried but i dont understand pins.

I have one stepper on pins 4-7 with digital out d0-d3, and i have pins 8-9 with digital out d4 and d5. I need two more pins and digital outs.

How do i get d6 and d7 to run together with d4 and d5 like on video for second stepper?

What is "controllino" ?

Post a link to its datasheet or user manual.

What stepper motors are you using - post a link to their datasheet.

Stepper Motor Basics

Controllino - https://controllino.biz/controllino/mini/

Stepper - in attachment is datasheet

Link where controllino runs 2 steppers

Code

Stepper myStepper1(stepsPerRevolution, 4, 5, 6, 7)
Stepper myStepper2(stepsPerRevolution, 8, 9, ?, ?).

I canot find output no in upper code

The Controllino page says its outputs can provide 2 amps.at 12v

Your motor datasheet says it has a coil resistance of 2 ohms in bipolar serial mode. If you provide 12 volts to that motor it will try to draw 6 amps and either the Controllino will be fried or the motor will be fried.

That sort of stepper motor needs a specialized stepper motor driver that can comfortably supply 2.12 amps - I suggest a driver that can at least provide 3 amps.

Have a look at Stepper Motor Basics

I understand risk and thanks for effort. I m checking possibility, but i dont know how to run stepper on d4-d7. On video it works.

I need to find out is it posible and how?

Hi,
Welcome to the forum.

Please read the first post in any forum entitled how to use this forum.

Can you please tell us your electronics, programming, Arduino, hardware experience?

Thanks.. Tom.. :slight_smile:

Hi Tom,

I m agronomist who is trying to drive camera on slider with stepper motors, i drive now one stepper on x, now i need y.

I m wondering can i do it like in video and how?

My expirience is basic, and i use Controllino mini and stepper at this stage.

If you insist on controlling your stepper motor directly from your Controllino then you need to get a motor that won't take more than 2 amps at 12v. Something like this would meet that requirement but I have no idea whether it would have enough torque for your project.

For the motor in the PDF in Reply #2 an external stepper motor driver is essential.

Thanks Robin2,

I will go in future with driver for stepper.
Untill i buy it i m wondering does someone knows how to control it like on video.

I know pinning for stepper 1, but for stepper 2 is a question?

Stepper myStepper2(stepsPerRevolution, 8, 9, ?, ?).

From what I see in the video, it looks like
Stepper myStepper2(stepsPerRevolution, 0, 1, 2, 3).

Jacques

Digital 0 - 4
Digital 1 - 5
Digital 2 - 6
Digital 3 - 7
Digital 4 - 8
Digital 5 - 9
Digital 6 - A4
Digital 7 - A5

I used pins 4-7 for stepper1, for stepper2 i have 8+9 - how to use A4 and A5?

Thats why i say:

Stepper myStepper2(stepsPerRevolution, 8, 9, ?, ?).

If you look at the video:here
you will see where the second servo is connected (in black).

I understand but which pins i should set a question marks:

Stepper myStepper2(stepsPerRevolution, 8, 9, ?, ?).

I understand but which pins i should set a question marks:

Stepper myStepper2(stepsPerRevolution, 0, 1, 2, 3).

8 should be replaced by 0
9 should be replaced by 1
first ? should be replaced by 2
second ? should be replaced by 3

If you have the same servos as in the video:

Green wire goes in plug 0
Black wire goes in plug 1
Blue wire goes in plug 2
Orange wire goes in plug 3

Jacques

Digital 0 - 4
Digital 1 - 5
Digital 2 - 6
Digital 3 - 7
Digital 4 - 8
Digital 5 - 9
Digital 6 - A4
Digital 7 - A5

Here is pair for digital output and pin in arduino. So it is not from 0-7 but 4-9+a4-a5

If you insist on this pinout, then I believe I am not able to help you further.

Good luck in your project.

Jacques

Jacques, i tried what you suggest but i dont get signals like i need. What ever i tried i couldnt use d6+d7 like you say.

Can you explain to me;

I have one stepper on pins 4-7 with digital out d0-d3

what pins 4-7 refers to, and what digital out d0-d3 refers to?

Digital output. In arduino code
Digital 0 - 4
Digital 1 - 5
Digital 2 - 6
Digital 3 - 7
Digital 4 - 8
Digital 5 - 9
Digital 6 - ?
Digital 7 - ?

Digital output of what? Controllino? Arduino? Stepper?

Arduino code, or Arduino pins? in this case, which Arduino model?
