Re: Digital Readout software - packages on the net for Linux

David,

Mach 1 and 2 can also read encoders in DRO mode. And provide the full
CNC later when desired. In fact Art even posted to this list in the
files section a DRO OCX. That might get you going more quickly unless
you're a "penguin" <G>

Hope this helps,

Ballendo
