Are you making more corrections than expected? This may be a consequence of incorrect dimensions input in your system. It is crucial to take the distances with the most precision possible; those distances will affect all the calculations thus the corrections. Don’t forget that the same principle apply when you are doing an alignment with dials!

Laser Alignment and Readings Repeatability
After taking readings, with a laser alignment system, when making corrections, how often do you have to correct and correct again? Frustration sets in? Precision
