There are lathes that do that already. The lathe is temperature
controlled and the slides run on air bearings with a tolerance of better
than 2 or 3 nano meters. The job is given in 10 micron steps and I have
to work the gcode from there

Gmoccapy is not the issue, as you can add more digits to the DRO on the
settings page. But if you speak about 0.1 µm it is useless to build a
lathe on that accuracy, as you will never be able to turn a part at
that accuracy. Just a few degrees temperature difference will destroy
the repeatability.
Just calculate 1 Degree is 1 µm length difference on every 100 mm.

The DRO's will have to be modified a bit I suppose. In order to show
the larger travels. The max travel is about 300mm.

The question I have is - will I be able to control the lathe to say
0.1
micro meter with Lcnc using the Gmoccapy front end.
You could easily configure the machine to use microns as the base
unit
(then G20 would work in thousandths of an inch).
