Yes, and that can only happen if there are wiring issues or if the axis got stuck for a fraction of a second and then continues. There is simply no way that that's caused by my probe macros, especially since I tested on mine with identical parameters. Obviously he made some changes, now his probe is higher up, not dragging the wires, and the probing distance is different... and so on. UCCNC uses G31 to probe and the movement stops automatically by UCCNC when the input is triggered. Same as my macros in that aspect.
