I have my system working almost perfectly. Pretty arrow straight drilling, however I have a problem.
I line myself up with the AB line at the start of a run, off I go, but even if I sit dead on the line, I press my steer switch and AOG veers me off 12 - 20cm from th line before bringing me bak again.
If I drive manually for the first 20 metres, then press steer swtch, it works fine.
Aquire look ahead is at 3.5, hold look ahead at 2.
Makes no difference if aquire look ahead is from 2.5 to 5.
Ah yes, ok. Well that does perhaps make sense. Sometikes when lining up, the tractor icon is sitting at an angle to the ab line when im actually driving straight. Not when the problem described happens, but its perhaps not noticable.
Ill turn it down to 70/30 tomorrow and give it a try.
