FastFieros(rusted space frame?) I'm not being a jerk, I did what you are doing, its how I was taught, I didn't know $*!t at that point, I was green. I've since learned a lot, and now its my ass and my money on the line so... Play with your fixture offsets, it's really simple.
I've said it before, and I will say it again, NEVER EVER EVER use SETX or SETY or SETZ, or first space bar menu #7(axis zero) to set any kind of part offset. SETX and SETY set your home position(E0,G53). That is the position that ALL of your offsets are based off of, by changing your home position, you are rendering all of your fixture offsets useless.
I leave my home at my Cold Start, never have to use SetAnything. My post sends my table to E0X0Y9.5 at the end of all programs(4020) so I can get to my vises, I do adjust my X position in my program if I'm working on one end of the table.
Here is an example of what I do and why I don't want my Home position moving around. On one machine I have 3 vises, they are all lined up nicely. With no jaws in them, the bottom left corner of the fixed jaw on each vise is assigned an offset. Left is E21, middle E22, right E23. On the other machine, two vises and a 4th. E21 for left vise, E22 for right vise(in the middle of the table) and E19 for the centerline of the fourth and the face of the jaws of the 3 jaw.
So on Monday, my first job is some stupid BS thing that can be held in some simple stepped jaws that need a few reliefs. I open up the
Cam program. I draw my fixed jaw, it takes a whole 3 lines, I make a few other lines keeping in mind my jaws are 1" thick and I'm going to cut them with a 1" spacer. I'm going to make a relief at the top left hand corner of my part, that is going to be E21X1.Y-.7. Draw the part right on top of my jaws I just cut, and run them with offset E21. The second op is an easy single hole, wide open as to location, I'll just not put jaws in the second vise and run E22, 1 program, 2 offsets = 1 complete part per green button push. Now for 4th axis work, already having the center of that sucker set at E19 will save tons of time, however if I use a SETX or a SETY, I move my home and I've just lost the location of all the knowns I have on my table.
Fixture offsets are your friend and the Fadal with the E#s and the utilities, 1st space bar menu #4 (set fixture) is by far the friendliest and simplest machine I've ever set a fixture offset on.
