hi all. have a problem with homing in mach3. y and z are fine. on my x axis i hve two ballscrews with two motors and two drivers, x and b. they are slaved together in mach. when you jog them they re fine and move as one. when homing, z goes first, they y, then x but not b so it tries to twist the axis and then stalls. how do i get around this.
