This is kind of off the subject but may be useful in future releases. On haas machines they have a parameter called grid offset for each axis. Basically it is a parameter that will "offset" the index pulse. This way you can control where your machine zeros without having to fool with the encoders.
When you set it, the control tells you how far you moved from the switch to the index pulse. Haas has a value that all machines need to be. Like 0.1 inches from switch to encoder index. In the grid offset parameter you enter the number of pulses to "shift" the index pulse to get the 0.1 On high pitch ball screws the location of the index pulse could move your zero a lot. They did not want people messing with the encoders and causing other problems so they have the parameter.
