After getting setup in the field over the last few weeks, and testing in a levelish field / getting good results, today was a real life test… Having some problems with it following the line on the side of a hill, and a little confused as to what I should be seeing on the screen or shouldnt.
So I am using an MMA on the PCBv2, x axis, and have zero’d it out in the yard on the level… it seems to report very similer angle to the greenstar in the same place, so seem to be working…
However, when running today, A-B lines on the side of the hill, I dont seem to be able to get it to stay on the line, it will always run 30-40 cm to the side. From my understanding, the roll value, is used along with the antenna heigh value, to calculate the amount of sideways movement at the antenna point, which is then added / subtracted to the GPS position to compensate for the fact the tractor is at an angle? So as far as AOG is concerned, level, or side hill, it should still follow the line, and be aiming for 0cm error on the lightbar… Is this correct?
If that is the case, why would I be seeing this problem, it will happily drive a straight line, but sits 30-40cm off to the right, however it doesn’t “attempt” to correct it, so doesn’t seem to be a steering issue, as if you view the steering chart, set point / target are right inline with each other, it just seems to be happy to go along at that point, sometimes will even get 50 -60cm, and then it will flick to next A-B line! and drift again, then flick again, and end up driving diagonally down across the field!
I am using PP, and tried dropping the lookahead a bit, which didnt seem to make much odds, the only setting that did, was the sidehill drift compensation…but I thought this was meant to be to move the tractor PAST the A-B line on purpose, so that the implement would then follow the A-B line to account for drift on the side of a hill? by adjusting that, I could get it to come up to a better position in the outside world, but obviously still appeared off on the screen…
Am i right in thinking that no matter what is going on, AOG should always be aiming to drive the tractor towards the A-B line in all situations on straight track? In which case, what could cause it to happily drive along next to it, but not on it.
Have confimed WAS 0 many times…and when on level ground, it will follow the line +/- 1-2cm normally!
