Steve, just a thought, and I never work on wire machines but they use the same technology as a cnc mill. A wire cuts with very little force inputted to the slides, look up your backlash compensation parameters and add the 0.0008 to the value allready in there. Retest for accuracy and adjust as needed. Thats what cnc controls are really good at, compensating for geometrical errors and slop in the screws. On a maching center with the high cutting forces, you can only go so far before you have surface finish problems, but your machine probably has linear slides and this may fix your problem with zero cost. I think your auto lube system is not a bad idea, just turn it way down low. Bill
