Re: [CAD_CAM_EDM_DRO] Large Linear Robot Base Axis

I need to get rid of a servo driven rack and pinion type linear robot basis
axis with about 20' of travel. It has some sort of Sony linear encoder for
the whole length and a Baldor geared servo motor drive. If anyone is
interested, e-mail me off-line at cavlon@....
