If your Y plus is toward the back of the machine, and your homing sensor is toward the back of the machine, you home at 30 not at 0. your HOME_OFFSET will be 30.1 HOME will be 30 HOME_SEARCH_VEL must be positive Alternative like Z your Y works in negative if you home at 0 at the back Alternative you home to the front at 0 Alternative your Y reverse your Y from normal Cartesian, but this breaks a bit of everything fcode compatibility wise everything is mirrored, but most cam have mirror Y function I believe.
