trying to calculate the thread pitch for metric sherline mill

Hi All,

I need some help. I have the motors hooked up to the Xylotex driver
board with turbocnc. It all seems to work, ie. motors spin properly
in the right direction.

My problem is that I am not sure what the thread pitch in mm of the
sherline leadscrew. I need the this information so that I can
calculate the steps/inc. in turbocnc.

Thanks for your help,

Les
