Thats not what you sent, there, each inch was a -0.022" z move for each move I commented out in the first section, then it switched to -0.030 till it hit the straight section. Obviously this is test code, and I'm being a picky old fool. The teacher mode kicks in and I can't help myself. >>> That's what the rod taper is based on.

I think most of us would like to see how long a machine you have built as for fine fly rods in say 3 pieces, my imagination says you would need the two butt pieces to be around 4 feet each, so thats a 60" X machine. >>> Mark > >--------------------------------------------------------------------------- >--- > >_______________________________________________ >Emc-users mailing list >[email protected] >https://lists.sourceforge.net/lists/listinfo/emc-users > -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
