Hi there,

I have a little (Chinese) Unimat 4 imitation on its way for the sole purpose of being modified and for me to 'tinker' a bit with a CNC lathe.

I have converted a mill to CNC so have a good idea of what is involved. I am, however looking for an idea of what kind of stepper motor size I should be looking for on this lathe (it is just like the Emco Unimat 4). Any ideas???

Another question which I have been scratching my head over a little, is how to set the zero position on one of these homemade CNC lathes for the x-axis (I think that is the smaller axis of the two...). How is this done accurately and are homing switches a good thing to have?

Thanks
Warren
