OK. Then you could try the svst firmware:
If you look at this, for example,

It is designed around a specific harmonic drive and very

The design is meant to be a good fit for his Deckel milling machine

Because in both cases 7i39 cards were used to drive servo motors and
default firmwares for 7i39 (for 7i43 and 5i23) do not contain stepgen,
I would like to know more about that design please.
And what cad software do you use?

Nice bit of kit, and servo driven at quite a speed.

Do you mean 5i25?
Rather than use a real parport, put a parport breakout on the 5i25
