I would like to take a look at it from here, but my english is not good enough to understand everything orally.

Hi,

I am too starting to experiment with AOG autosteer settings. I used it to seed my wheat last week for the first time, first it was hard to get it straight I finnaly got some stable results. First like Brian said counts per degree is very important, a small change made some big difference, to adjust it I set my counts/degree to 1 then turn my wheel to exactly 15 degree, measured with a protractor, repeated for both sides. I then divided the displayed number by 15 to give me the counts/degree. After I increased my minimum PWM until the motor reacted to minor changes. Started with look Ahead and min Look Ahead around 2.5 each. I played with each variables one at a time first with major change to see the reaction and finally just minor changes. I have a 12 volts 300rpm gear motor, my final settings are look Ahead 2, min Look Ahead 2.5, Prop Gain 22, output gain 11, min PWM 29.
