hi all,
i am using mach3 on a lathe that i've just finished the cnc conversion. i've set the x and z drives to go home at power up. so the limit switches are on the drives not on mach3. on the software i use the soft limits, and it works fine. when the axes are at home, i reset the machine coordinates and then i can move the axis whithin the soft limits and the software will not allow the machine to move outside the limits, and this is what i want. the problem is when i set the work zero. then the machine coordinate and the soft limits apear to move to the same spot. for example when the z axis is at home (tailstock) the machine coordinate is set to zero, if i move the axis to the left at -10 and then set the part zero z, i can no longer move to the right of that point because the soft limits now apply to that new location, neither can i see the original machine coordinate. is there a way to have the machine coordinate stay set to the same spot for the whole session?
