Sorry to resurrect this old thread. Does anyone know the voltage ranges I should expect from the hall effects sensor as measured at the "sensing" pin of the four pin connector connecting the motor and the slave board?

I'm seeing a range of ~2.4VDC to ~2.6VDC going from extreme left to extreme right (moving by hand).

That would be great. Thanks!

I did additional testing and found that the coils stay engaged even when in attract mode (snaps to one side if I manually move it). So I likely have some board or interconnect issues as well.
