I am using 4 axis and I need when move all axis to zero first X and Y after this Z and A. Today happens this way:
when I click GotoZ, X Y and A go to zero and after this z go to Zero.
What I need to mach3 do this sequence?

Thanks

You would need to make up a VB button if you wis to do the sequence differently as the GoToZ is coded into Mach.
 Having said that maybe all you are needing to do is set a safe Z, if you do that setting the safe Z as machine coords 0 then what will happen when you GoToZ is the Z axis will rise fully up the X, Yand A will go to your offset  zero then finally the Z will move down to your offset zero.
