Z axis setup in Mach3

[3fingersshort]

Hi. I'm having trouble setting up the Z-axis homing and limits in the Mach3 dialog box. I had it figured some time ago, but lost everything when my computer crapped out on me. Can anyone tell me how this is generally set up. I don't have any limit switches, and I'm not sure about soft limits, but I'd really like the Z to stop crashing about unpredictably. Thanks.

Go to the config menu option, select “safe Z setup” that is one way of doing it.

Not sure about other cam programs but Vcarve Pro also has a setting for the Z clearance settings that I use.
