You've figured out how to get to the probing VQC templates, right? Or is that the problem?
  1. Press Edit to get into editing mode (won't work from Mem)
  2. Press Prgrm/Convrs three times (until you get to the black VQC screens)
  3. Press F2 to get the template selection screen
  4. Down Arrow until you get to O09996 Renishaw VQC Probing
  5. Write/Enter
I do a vise corner in three steps. The probing template comes up with a bunch of choices. I use the Probing 1-9 templates. For most vise jobs, I put a work-stop in/on the left side of the work. I clamp a 1-2-3 block on there so I have a known square corner. That's almost always left as my G54. I program everything in Mastercam using that corner so I don't have to change setups.

Then I probe (using MDI for each cycle):
  1. The left edge (work-stop) using X Plus Surface
  2. The back surface (fixed jaw) using Y Minus Surface
  3. The top of the block (the parallels plus the block) using Z surface
After this, I go into the work offsets and subtract an inch from the Z work offset (to remove the 1-2-3 block height). This puts a fixed origin at the upper left corner, down on the parallels. I use this setup for almost everything I do that starts with a rectangular shape.

I see that there is a combination cycle in the second probing menu for doing a corner. I guess that would take care of two steps but it looks like you still have to probe the Z surface. In that case, it looks like you specify which corner you're using by inputting a number from the template display.

If I felt that I was 'wasting time' doing the three steps, I'd go to the trouble of combining them into one program. It goes so fast though, that I just haven't bothered. It's also good for me because I go through the motions of swapping screens, using the keypad, etc. It's reinforced my learning of the control which is more important to me right now, than outright efficiency.
