Hubert, I depends on the accuracy you are looking for. For machined metal parts you will need to have a Z marker pulse on your encoder. The limit switch only serves to position the slide so the home search will find the marker pulse on the same revolution of the ball screw so the home position is repeatable to a high degree of precision. thanks Stuart
