    metric lead screw help

    Hi, I have a metric lead screw on my Z axis (Momus build) and I have no idea how to calculate the motor steps. I have Mach 3 running a Gecko 540 with Kielings motors, the lead screw is listed as an SFU1204-3, I have been able in the past to work out Imperial Acme screws but the metric throws this old brain into total frustration. Any help you can offer would be appreciated.
    Thanks
    Terry

    On the Settings page, just above the Reset button, click Set Steps per Unit and Mach3 will do the calculations for you.
