I had a need to use this cut registration method earlier today and it worked very well, I was able to make an expensive and important cut with confidence before the cut; that my previously cut work piece which needed an additional cut made on it was correctly registered/aligned with LB’s workspace and corresponding shape design for the additional shape cut. The problem causing the need for an additional cut had to do with a glitch in the plasma THC during the original cut, and noticed only after I had removed the work piece from the CNC bed. The fix was two step: 1) to redesign the horizontal slots noted by the red check marks in the pic; I used the LB “Offset” tool to make the slots 1mm larger in all directions to correct an edge imperfection from the original cut, and 2) then I used the method described in the original post here to register/align the LB group shape to the work piece as it now lay only in proximity to its original location on the CNC workarea bed. I was able to “dry run” the cut with a needle pointer in the Z head (in place of plasma torch) to ensure that it traced/scanned exactly where I expected it to do so on the work piece. Only then did I swap the pointer for the torch and proceed to make the new/added cut; it went perfectly. The red check marks indicate the 2 points on the design that I used “Two-Point Rotate/Scale” tools as my registration points.
Cheers,
Lou
