My better idea didn't save a mult2 but by re-arrainging the order of things now gives me straight from the mux8, a value that when multiplied by the joints scale, gives me a count that represents a movement of .0001" movement per click as the base move. This same value could be displayed in the gui to tell the operator how far, in machine units, it will move for one click, but I've not yet cobbled that uop in .xml.
This 2.something is then multiplied by the encoders .count and will be fed to the joints jog input. So I believe I have the x axis behaving as I want. Doing z then is a copy/paste and a bunch of renameing here and there. If, when I actually get the dials mounted and wired up, I don't have to invert or correct a few somethings, it will be a first! But as I said, the first day will be running a vacuum cleaner, its a mess right now, and I need to finish an x-out home switch, so tiny I couldn't find it if it gets knocked off the resting place, and waiting on a 2-56 bottoming tap. z-home is yet another swarf generator project. And I should do a whole batch of z limits.

Yeah, but the way I've done this, it should be as accurate as the scale factor for that joint so if its wrong I'll set the dial up and see if an inch is still an inch. :) Famous last words of course, Murphy is back and drinking my beer again. :) > Erik Cheers Erik, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
