Turret problems

[Mike Bos]

I have problems with Motor control B.
...i think.
The previous owner also had this problem and he did not find the problem.
I checked all the wiring and bought a new receiver but the problem remains.
What's happening?
Sometimes the tower starts rotating spontaneously.
This happens very slowly and when i give the trim a few taps the problem is mostly solved for now , but when you turn off the tank and then use it again the tower runs slowly again.
Has anyone ever had this problem? The barrel moves as it should.
It is noticeable that when I move the barrel...the dome sometimes also makes jerks.
In my opinion, the problem lies in Module motor control B ... can it be calibrated or reset?
Please give your opinion.

Are the BEC outputs disconnected from the B module, that could cause some issues on the R/C circuit.
Some times R/C incomparability happens. it's painful,
My Taranis didn't like my motor control B module, so I changed the speed controller for different manufacturer.
Now all good.
Sorry this is not much help, but sometimes you have to try different equipment to find a solution to the problem.

I had the same problem with the M3 Lee, if u have the red boxes probably the dip switches on the motor controller are set wrong.

1=off
2=on
3=on
4=off
5=on
6=on

Best regards,

Dip switches should be looked at as up and down referenced by the numbers.
My dip switches on the speed controller came with dip switch one only in the down position. Which switches off the mixed outputs. Dip switch 4 switches on the acceleration ramping in the down position, apparently for smooth acceleration on large robots.
Auto calibration dip switch 5 is on in the up position.
I think you can set it up manually but you need to read the instructions.
My problem started after 3 minutes after switching on and I couldn't stop it with out switching the whole thing off.

Hope this helps

Thanks for your response.
I apreciate the reactions and the many tips.
Lot of things to look at next week. (But hopefully this weekend )
I keep you all informed

In one of my tanks, i have the silver boxes and every so often, the barrel decides its going to elevate........you gotta be quick to stop it else geometric lock follows

Thanks to you the problem has been solved!!!

Initially I started with the wiring.
I had replaced all the wires to the receiver to just the yellow wire.
So I removed the red and brown wire.
But then nothing worked anymore.
so the wiring was restored to 3 wires again..
Then I opened the red Box Motor control B.
It turned out that the 2nd and 4th dip switches were indeed positioned incorrectly.
Ultimately I had to remove the red cable from the turrent wiring. The rest now all have the three cables from receiver to both boxes.
Problem solved thanks to your input!
Thank you, thank you and thank you again!!

I am very happy with the result, which both the previous owner and I struggled with.
