I laso tried to increase flux by adding magnets but the result not change. Im already satisfied with this setup but i was wondering if this is normal.


One thing I forgot to mention - you can get 3000 steps over 180 degrees, but what can you get within the extents of the axis that you intend to measure? In other words if you are only measuring +/-30 degrees, you'll only have 1500 steps.
