hey there. im thinking about getting the igaging remote dro (basically digital caliper without jaws and a little box on a wire that houses the lcd display.) for my sieg sx2. i have the micro mark one with the 20tpi leadscrews.
the dro im looking at has only 0.001in resolution (same as hand wheel lines) but they only have .002 in accuracy. do you guys think this will be a step up from the standard screw? i seem to have difficulties getting features exactly where i want on parts sometimes. thankfully i never need to go super accurate, but more is always better as far as accuracy. im just wondering if the feed screws are already more accurate than 2 thousandths. the dro would be nice for doing occasional metric work, and just make life easier. my little mill seems to have alot of "spring" in the controls, as in, it is hard to tell when the wheels actually move the table, or if it is still taking up slack and flex in the system. the z axis is especially bad with this issue because the power has to go through a shaft, then through a worm wheel, then to a gear, then through a castle nut, then through another shaft to another gear then to a gear rack and then through the screws that hold the gear rack on, and then the head finally moves lol. so if you can imagine, i turn the "fine tuning" wheel, and it gradually increases in tension until the head actually moves, and its hard to tell when that happens. i know for sure that even a 2 thou accurate scale will improve my z axis, but im not so sure about the x/ Y.
