2 dof with ibt 2 and smc 3 problems

Hello,
i build in the moment my 2 DOF with 2 ibt -2.
I use the Instruction from here
https://www.xsimulator.net/community/threads/smc3-arduino-3dof-motor-driver-and-windows-utilities.4957

I have change the arduino Code to mode 2.
I have conect the potis to the Motor in midl Position.
Now whene i start smc3 The Motors do nothing but until i turn on the potis the Motor run. But only in One Direction!! I have Check the wirering but its the same like the diagram in the Instruction posting.
what is wrong?

Pleace help me!

Greetings

This is my project.

I have 2 Bosch WhiperMotors
2 IBT 2
1 Arduino uno

But now a big new problem.
I have destroyed both ibt2 and the arduino becaus i have made a big fail :/
The new parts comes tomorrow.

But bevor this is hapend:

I have managed that at least the motor 1 moves in both directions
For the first time that the motor moves as it should be in the smc3 as a motion juhuuuuu


But unfortunately not in the area I would like so the path was much too small. I've changed the limits and nothing has changed. After that I pretended wildly and then nothing worked anymore.


The second motor didn't do anything yet. I then swapped the two ibt2s and it still didn't work. so one of the two is apparently already broken.
The second one that actually went got a short circuit because of me and since then it doesn't work either : /
and this was the moment when the arduino was died...



Luckily amazon delivers very quickly

The PC Powersuply is only for the cooling vents and my wind simulator.

Thank you for your hint!!!
As you can see in the picture, 3 cables come from my motor.
One ground one plus and one more.
I just cut the gnd off (it was on the motor housing).
So was that wrong? Is this where my fault lies?

Unfortunately I don't understand the drawing as it is meant

why does the + and - cable go from the power supply to the black cable on the motor?
and so i have to go to the housing with the + and what happens if there is electricity?
and if none of them flow? How does it have to be?





Edit:

the way I understand it.
Some wiper motors have the housing grounded, which is a problem when attached to a metal frame. If the motors run in opposite directions, your power supply will be shorted out. Which in turn destroys the motor h bridge


So I understand it that if I hang my continuity tester on one of the poles and then go to the housing, there should be no continuity.
That's the way it is.
if I of course use the brown mass cable then of course it is already like that.

Does that fit now? I don't know

Check these settings and check in your computer

Hello friends you can help me I put a video so that you understand my problem a little better thank you.

It's hard to say anything based on the film.
A few comments:
1. build some kind of stable structure for the potentiometer
2. the motor in the “monitor” mode does not control its movement, on the video you can see that something gave it a signal to move and “turned” the potentiometer out of the measurement range and any movement of the motor causes overshoot and OFF the motor
Do it properly and it will work, in the rest position, that is, the green line in the middle of the SMC3Utils screen, the voltage measured at the output of the potentiometer should be about 2.5 V
The potentiometer has a movement of 360 degrees, but the useful range is usually 180-270 degrees, and turned out of range will turn off the motor.

hello thank you for your answer as you can see when you turn the potentiometer by hand the motor it works well in both directions it is when you connect it with the motor there is something that does not turn well at all way I have already disconnected the 5 volts plus the GND of beam on I have reversed them but nothing has changed I will try to pour the right side and left side of potentiometer to see if there is something wrong I already have the motor support in the simulator which goes with the 24 volt motors I will put that aside to do a test like that it will be better for the sport it will hold the potentiometer in place and we can see on video I will keep you informed for the rest THANKS.

hello I put a full video on this message to be able to see my problem thank you all

From the video you posted not much can be seen, what could be noticed is that certainly the green line (signal from the potentiometer) is not in the center of the screen as it should be.
Here is a video of how it should look like, the green line in the center of the smc3utils screen, when I select Sine the motor starts to move, when I select Manual I can manually control the movement of the motor and at the end it centers the motor in the neutral position, the green line returns to the center of the smc3utils screen.
In addition, you used NANO board instead of UNO R3, theoretically they are the same but all projects I have seen so far worked on UNO R3.

hello thank you for your help that's it the motors they are running being able to advance the simulator Thank you

hello I have another problem now I would like to make my motors move with the LFS game but there is nothing moving there is no communication what adjustment I should make thank you the juice it is already patched I will post a photo. thank you

thank you
