Sieg X3 Conversion

[komatias]

You are right, damage can be done if the steps are lost but at least you will be able to tell and the drives can be wired in such a way to tell the control software that they lost the steps. Servs will have this too to some extent

To reduce the likelyhood of having lost steps in the first place, you have the motion controller.

It goes without saying that you will need to buy the ballnuts and screws as a matched pair like dodgygeeza notes.

What I don't get is why they say you need to index the spindle to the z-axis, unless of course you are doing rigid tapping. Mach3 cannot do this anyway unless you treat the spindle as another axis or use a servo. Even tormach agrees http://www.tormach.com/blog/getting-...hread-milling/
