This is kind of s general question for my info. I have a CNC router/plasma machine. When I reference home in the router xml the machine goes to the limit switch touches and then backs off and zeros out like it should. In plasma xml mode it goes to home switch touches and stops dead, some times it zeros out sometimes not. Its not a big deal as I have lived with it for almost 7 years. I am just wondering which setting would cause the variation in homing. Thanks
