My Autozero shows that my circuit is complete by showing the green light when I lift the autozero plate to touch the bit BUT THIS OCCURS EVEN WHEN THE WIRE WITH THE MAGNET IS LAYING ON THE SPOILBOARD. I noticed this recently when I forgot to connect the magnet to the collet nut and after zeroing the bit did not go to the correct zero location. It pushed the plate away from the workpiece to the left. IS THERE A FIX FOR THIS?
