RE: [CAD_CAM_EDM_DRO] Re: Gecko + Servos + Taig Mill

With a 200 line encoder the jitter is only .45 deg. With a 20 tpi lead screw
(Sherline) and a direct drive this is only a movement of 0.0000625" at the
table which is too small to actually occur. Even with a 10 tpi screw and
direct drive it is only .000125" which is likely below the amount required
to actually move the table. So other than some buzzing I don't see where it
would make any difference.
