I use hall effect trigger switches for each of my axis. Yesterday I ran my machine and everything ran as normal. Today I noticed that my machine seemed to be cutting deeper. I checked everything out. And I noticed that my Z axis which used to trigger at a point of 6.959 above my table now triggers at 7.0469 above the table. A change of .0879" over 1/16 of an inch different.
I trigger from a steel bolt through the face of my z axis, and a hall effect through the face of the Z mounting plate (Top down pic included, couldn't get a good side view pic). Both the sensor and the bolt are still tight.
So how could the trigger point have changed with nothing else changing?
