Re: mill and steppers

Hello Jon, thanks.

The machine will probably be:

maschinen.de/opti_neu/home/ANZEIGE/MASCHINEN/PRODUKTE/FRAMEBF_20VARIO
.HTML

(sorry, it seems that there aren't info in english in the web about
this machines)

Perhaps it could be another machine, slightly smaller or greater, I
haven't still my final decission. I don't know the screw type, but
surely not ballscrews.

The torques of my motors are: 3 Nm (424 oz·in), 4 Nm (567 oz·in)and
4'6 Nm (652 oz·in).

My idea is not to move the knee, though I have another motor (567
oz·in) for a fourth axis.

Best regards,

Sattwa.
