<div dir="ltr">Well perhaps us hardware types could meet up one night during the week to get it up and running or at least figure out the best way to run it.

</span>They are of no use, they are designed only to talk to well behaved<br>
devices using the defined protocols, you cant bit bang (waggle<br>
individual lines) with any kind of speed or accuracy.<br>
<br>
An interesting alternative suggestion is that if the existing controller<br>
board is of the really dumb type, with just step and direction inputs,<br>
then it may be possible to use a standard arduino and firmware and wire<br>
up the parallel connector as if it was a bunch of stepsticks.<br>
<br>
I just dont know enough about the mills hardware to speculate further<br>
