Resolved problem with center in simtools

When I started doing this project, I had this problem, but besides it there were many others that were successfully solved. The problem is that when testing the axes, my position changes by 20 degrees, and if I change the position by even 1%, it suddenly becomes centered, which I set using SMC3. I saw a post from a person who had a similar problem, but changing the system language to English did not help. The settings in simtools are standard; when you change the drive type in the settings from linear to rotary, nothing changes in simtools v3, the same thing. The settings were selected in SMC3, which I think are ideal and the problem needs to be looked for elsewhere.
Motor Driver: Citron MD20A
Platform: Arduino Uno
Position sensor: 10K potentiometers
(there is an idea that Arduino does not understand what 0 is and it turns out like this)
I ask you to help me a lot as this is the only thing that stops me from using this simulator.

Please note that changing to rotary does not change anything

Does anyone have any idea? (even the stupidest one)

I'm still learning this all just as you are, but you wouldn't happen to be running both SMC3 and simtools at the same time, would you? I learned the hard way, it caused my sim to collapse early in my build and almost crushed my unmounted psu's. I had to reset and recenter all my SMC3 settings afterwards.

not using. Everything is fine with the power supply, 2x600 watts. The same thing applies to the motor controllers; they are new and have not been properly used.

I just noticed that the Arduino cannot understand what the simtools wants when you try to set the position below the center. The platform begins to throw and swing, but in SMC3 everything is perfect in any position and the movement is as smooth as possible.

What version of simtools are you using? What is your profile intensity slider set to?

I used version 2.6.1 and v3 the problem in v3 is repeated. I don't quite understand what you mean by the intensity slider.

On bottom right of my pic, there's half of an orange dot. That's where the slider is. I had mine set at 10 for initial testing and almost got thrown out of the chair. I have it set at 1.

when set to 1 and 100 nothing changes

as soon as I initially set the position to 51 it falls into place as in SMC3

this is what the curve looks like in SMC3, for me this is an ideal result, but in simtools something is going wrong and I don’t know what

Is that sine curve with you in the seat and under load? I'm not familiar with the motor drivers you're using, so I cannot comment any further on settings. You have mentioned the Arduino several times though, so if it were me in the same situation, id reset/clear all settings, download/reload SMC3.ino, double check the correct mode, and start from scratch. I have done that, and it only takes a few minutes. Couldn't hurt.

I just did all this and nothing happened, I repeat, what does this happen when the simtools is set to zero, but if you move 1 percent to the right, I get it down and it goes to the correct position, but it doesn’t apply to the left Arduino, as if it doesn’t understand that the simtools is sending and the motors are needed lift. My mistake is that the Arduino seems to be fake, but then why is everything so good in SMC3?

I’m thinking of ordering an original Arduino for 30 euros, but for some reason I doubt that it’s the problem. Can you recommend something similar but not an Arduino? something that will work reliably

Were you sitting in the seat for testing in SMC3? You haven't made it clear if this happens under load or just an empty chair. That can make a large difference.

when I sit, electricity consumption simply increases (here is a graph with a load of 100 kg)

maybe it has something to do with it but when I started the game there was a huge delay

How many kgs do you weigh? Again, I'm not familiar with your motor drivers, but to me, your SMC3 settings seem low. I'm not saying to go start maxing them out, but from what little experience I have with my rig, mine are much higher and I weigh 170 lbs. I use IBT-2S. All I can recommend now is scour the forums for your driver type and find if anyone posted settings with a similar setup.
