Hi,
How far can you get with the pc printer port, and is there much advantage to be had from the motion controller cards? Also i hear a lot about using the quill as the z axis as opposed to the knee. Is this simply to minimise wear and tear on the heavy knee (slideways) for drilling and related operations? I am not a big fan of using the quill for milling operations, will you get good acuracy on the quill if you retofit a ballscrew and servo? lastly, is it essential to get the whole machine on ballscrews, or can you make do with the 5mm pitch leadscrews that are currently in place?
Thanx for all the help sofar
