setp x1 3.5 setp y1 -.003 setp x2 7.0 setp y2 .006 setp x3 11.5 setp y3 .002 setp x4 15.0 setp y4 -0.002 etc etc Between x0 and x1 it will interpolate that -.003, so at 1" you would get a -0.00085714285714285714286 correction out of it. ditto for the x1 to x2 range it will interpolate, even giving a zero correction at one point in that slide. A correction that is calculated and applied every millisecond in essentially real time. If you have a real bump at so and so, set a correction point on both sides of the bump. There is nothing there that makes you do the correction in precisely 3.5" bits of the travel. Reading between the lines Mark, it seems to me you are doing the saw in 1" increments because that is how you are doing the taper. That 1" limitation may be overkill when with lincurve doing the corrections, you might be able to do it in one 56" run. If its actually stopping for millisecond or so at these 1" way points, that could be creating some of the wibbles you are now having to plane off by hand. That cannot be good for the accuracy of the glue line thickness. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
