Hi, I´m working in a small factory witch just bought an old CNC lathe, is a leadwell LTC 20. with a Fanuc O-T control. The machine is almost ready but it has a problem:

Whether I use MDI or MPG method to move in the Z axis, it always moves the half programmed, I mean, the screen shows the desired measure, por when I Check with a Caliper or a simple rule, The Turret just move the Half of that measure.

Is there a parameter who control the magnification of the movement in Z axis? I don`t know, Please, any of you know how to fix this? Thank you in advance
