It is highly beneficial to use the soft stop setting in order to not damage the machine moving at a high homing speed that's coming to an abrupt stop. +6.

The Distance to Home Sensor has to be set up to be slightly higher than the maximum length that the working piece will have to travel to find the homing sensor. This depends on the particular size of your machine

The Gap Speed will describe the speed with which the machine moves between the sensor and the gap end:+8. It is sometimes desirable to set the homing position to be slightly further away from the edge at which the sensor is located, so that the Home position is not right at the very edge of the working space. Using the Gap setting, the user can add a gap between the sensor position and the new software Home position (5 mm in case of this example). The Gap Speed will describe the speed with which the machine moves between the sensor ​(located at the edge) and the gap end (located closer to the centre):

This is useful when a linear encoder is located ​a fair distance away, and is set to be slightly smaller (on the scale of nearly a millimeter) than the actual distance to the encoder. This setting is not necessary, however it does allow the user to lower the required time on the Encoder Z Home Detection. ​+3.
