Those look like reasonable values.

Maybe you could expand upon:
when I set wcs and hit cycle/ start the tool is not where it should be.
Where should the tool be, according to your CNC program?
Where does the tool actually go?
Where does the DRO position say the tool is?
What does the status window say about tool number and offset number?
Does your job file specify a different WCS than the one in which you set zero?

I set my WCS on a corner point in fusion as I normally would ensuring xyz are correctly oriented. I run the simulation in fusion and the tool starts at the top center of the part for a contour operation. Load that file to the machine and probe the point which I chose in fusion. Set x, set y, and set z. Run the operation and the tool starts heading for the center of the part. Maybe it's user error but I've ran similar operations when it was cnc11 with no issue. I'm just wondering if there is still a problem with the PLC with WCS that is preventing proper tool path. I will test some more operations tonight and document my results.

If it's just Z that seems wrong, it's probably a height offset issue. If X and Y seem off, it's probably the last item CNCSNW posited and you are setting one WCS, but your program is calling a different one at the start.

When you use the F8/Graph key in CNC12 to preview the program before you try running it, you can look at the scales/rulers on the Graph screen to see where the toolpath cuts, relative to the WCS X0 Y0 Z0.

BTW, the PLC has nothing whatsoever to do with WCS locations or G code interpretation.

It was user error. I made a mistake in my setup. Sorry false alarm. Did I mention I'm new to this :lol:
