I’ll take a peak at the relative servo.

Did you know that every servo control can specify more than one servo? Including reversing servos. Take a look here and see if that helps in the meantime: https://synthiam.com/Docs/Programming/Servo-Controls

Yes, thanks, I know that every servo control has a multi servo function, but unfortunately I cannot call it from a script and I need that.

If there is no long-term solution, I can write a small script for every position that contains the servo positions, and then call the small script from the main script.

But that would mean a lot of work with 10 servos and would be very confusing.

All other singel Servos works fine (no randrom movements on connect)

I'll take a look at it - stay tuned :)

No Problem... I upload a Video how it looks when i connect:

maybe it helps. Maybe the mistake is mine, but I just don't know where.

ok i was able to isolate the error. I deleted all servos from my project and wrote a small script. This should simulate a relative servo.

The script works. If I connect without the script working there is no error.

When I start the script and connect all the motors go crazy like in the video.

Although I deleted all servo controls from the project as I said.

This is the script:

:start

############# Flabs Hoch Runter v1 ########################### $SERVO_V1 = GetServo(V1) Servo( D8, $SERVO_V1 ) Servo( D10, $SERVO_V1 )

############# augen rechts links v5  ########################### $SERVO_V5 = GetServo(V5) Servo( D4, $SERVO_V5 ) Servo( D14, $SERVO_V5 )

goto (start)

The error seems to occur as soon as I use viritual ports.

I was hoping to work around the error if I didn't add a "Relative Servo" but wrote my own script that do the same... Now I am at a loss...

I made some fixes to the relative servo

Much better! Now the problem only occurs when I use a relative servo move from a script. And only the first time. After that I can also end the connection and reconnect, the error does not occur. Only when I disconnect and reconnect the EZ-B from the power and then control a relative servo with a script - then the error occurs again.

I always start and end the connection with all servos in the same position. If I only control the relative servos by hand everything works.

As I said, only the first time a script is started after the EZ-B has no power, the error occurs once.

wouldn't be that bad either, but I could break components if the servos don't move synchronously.

I can’t seem to reproduce the situation you’re experiencing. Can you create a basic project and post it in your response?

Yes, I can, but it takes a moment. Yesterday I put everything back together and when I controlled one of the "relative servos" (by hand and not immediately after the restart) the error occurred again and damaged different parts. Among other things, one of the original EZ-B HDD motors :-/

When I have fixed everything, I will try to reproduce the problem again in a clean project.

Thank you in advance for trying so hard.

ok i am one step further. I am now pretty sure that the problem does not come from the "relative servos". Could now produce the error in a script that does not use "relative servos". I still attached the clean project. I also filmed it again.

Any ideas what kind of hardware problem could trigger something like that? Broken motor? Problems with the voltage? (I'm using a 9V power bank) Wrong wiring?

it looks like the error is occurring in certain motor movements. You can see it quite well in the video.
