"Tractor tires are constantly moving – AgOpen V4.1"

Hi. I have AgOpen V4.1 with a Baraki hydraulic valve.
I have two satellite modules and two antennas. I have performed the assistant settings several times. However, the tires keep turning left and right even when the tractor is stopped—they won’t stabilize.

If I reduce the “minimum to move” value, the tires still keep turning left and right, just more slowly. But if I reduce it too much, the system doesn’t hold the line at all.

I have tried changing all possible settings, but nothing has improved.



What WAS are you using?

It is a good was, depending on how you mounted it. Hopefully no slack an use almost all 90 degree (80 degree is okay)

You should set max much higher 100 to 150, and Always over min!

If I turn the maximum above 70, he gets even more nervous. Can I turn on some graphs to see exactly what’s wrong?
Maybe try one of these sensors?


I don’t think the sensor is faulty, it would be very rare. Also I use the exact same.

If you have mounted it so it output around 2.5 v when wheels are straight forward. And was use almost all 90 degree.

Now show us what happens when you use the “drive” function in the expanded autosteer settings.

Do it with wheels straight ahead, and was show 0 degree.

I could think you have something inverted?

Like was or left right Coil on baraki (both can be set in AOG)

You mean, the wheels are moving when speed is 0 ? In this situation, did you have autosteer engaged? What happens, if you are in Manual?

Is there movement in gps position and jumps in speed/position caused from bad gps signal, during standstill?

Check out, if there is movement (wheels, gps position) in Manual mode.

Yes, the wheels move to one side and to the other when I stop for about 5 seconds, then the steering disengages. I’ll check the settings tomorrow.

Are you sure the wheels are propertly transfering the movement to the sensor, maybe it has too much play inside.

How can I check? When turning the steering wheel, the green indicator moves, but I don’t know how exactly.

Okay, turn left and than start turning right very slowly, if the wheels start moving before the green indicator than its not good. Try with right turn also since that sensor is spring loaded…

You seem to be right. Because turning the corner all the way and turning back little by little, nothing changes when turning almost 180 degrees, then the indicator just starts to react. It seems that the problem is in the connection between the sensor and the wheels. I need to see the connection point. Thank you for your support.

Maybe your problem is the lever on the was. Sounds like you are crossing the spot between the working halves of the was.
It have 90 degree at one half and also 90 degree at the other half.
If you measure the signal voltage, find the 45 degree center spot where you have 2.5 V . You will see 2.5 V at both halves.

I changed the connection, now the green indicator is more sensitive to the wheels. I was too happy. I put everything back together, but the problem remained. I’ll try to measure the volts. I will try to upload the video.

Have you tried Pure Pursuit instead of Standley ?

Where did you wire gnd and +5v for pressure sensor? If you use pin 4 Was gnd for pressure sensor also than that is also one of your problems… Was gnd must only be used for was.

I have never tried Stanley, so can’t help with setting for that, please use pure pursuit.
What did you change? Please show video of was when turning from full left to full right.
Also show video of using the manual turn on the expanded autosteer settings, turning from straight to full right, while we at same time see front wheel through window.

WAS GND connected correctly to 4 GND. Between gnd(4) and 5v high(2) there is 1v-3.7v from one stop to the other. The steering wheel is straight, then about 2.5v.
I did the full calibration again. Maybe something with the gps data? On the Teensy, the right and left gps modules were configured with “AOGConfigOMatic” each separately.Here is the video.

So you do not use full was angle, which makes it more sensitive. I use same was and have cpd set at 180. You have very few cpd which also makes it more sensitive.
Try 200 cpd and see what happens!

You did not use the manual drive function (the red tractor in the autosteer settings) make it green by touching it and activate autosteer. Then use the arrows beside red tractor to steer. I wanted to check that wheels actually turn left when activating left arrow! If not, then invert hydraulic steer.
