Using external alignment to run multiple parts instead of looping.

I'm really close to ditching any attempt to use looping in my program to try and run multiple parts on my CMM table (I would like to run maybe 6 max). I'm trying to use 1 probe to inspect all the parts features (measuring on part, then going down in -Y 11.5" and doing the same measurement, go down in -Y again etc), then change probes, and measure all parts the same way (measuring all necessary features of one part, and then going down 11.5 inches in Y). The alignment keeps changing on me from the first part to the second...and when I post the data, 1 part will have the alignment from the second part. So, everything will dimensionally be okay, but because the origin is shifted down in Y by 11.5 inches, everything is screwed up on the total positioning (even though I know these parts will pass). How can I save one alignment/ do an external alignment, and then just shift it down 11.5 inches? I am sick of using looping, I feel like looping is really only for like bolt hole patterns, and waffle grid patterns in holes. Measuring whole parts in different locations is giving me a nightmare. It's something about the tool change and multiple parts. Because the second part doesn't get it's own alignment (like if your DCC alignment was A3, the second part should get A3-2 or something like that, but no. It just drives off the first parts alignment. I need multiple alignments just like the first part, just in different locations. I'll post the code just for giggles.

I've seen your threads pop up but haven't really had time to chip in yet.

Can I ask why exactly you want to do away with the probe change mid program?

Unless the cycle time is really critical your just adding (imho) unnecessary complexity.

That said, if you go want to do it, the best option would be to use either a while/end while our a do/until loop, using external alignments to recall the correct starting positions, however, as you'll be looping twice (once with the first probe and once with the second, you're also going to have to save any alignments you generate within the first loop to recall in the second loop.

These will have to have a unique name i.e ALN_ABC_1, and ALN_ABC_2, you would do this by creating a counter for each loop..

ASSIGN/V1=1

then
ASSIGN/ALN_NAME="ALN_ABC"+V1

then save the alignment with ALN_NAME.

You would then have to recall those using the same method within the second loop.

Okay NinjaBadger I just re-read your original post to this thread where you were trying to explain to me how to use while/end and do/until commands. I feel like this might be something I was trying to express but just didn't have enough experience to complete. 2 other users have also mentioned solutions that sounded like it was going to fix the problem with the loops in this situation: louisd and Hi-Tech Redneck. Like you mentioned, there are many ways to skin a cat. And I just want to know every way to skin them because it will come up in my job somehow. I have a fair amount of experience with programming BASIC like TI-83s and 89s, and feel like I've got a handle on alignments:manual/dcc alignments/readpoints/iterative and using the program. I apologize again for trying to run so fast before I walk, but the job is just like that. Also, I'm used to programming with a HAAS mill, and I used to do the CAD/CAM software before I switched to metrology. CAM is just so different because most cnc machines today you set the origin, usually put stock in your vices and the machine trims all the datums/around the part and you inspect it later. Having to home each part in is slightly weird to me in the order of sequences/logic. In CAM, making a tool do every hole and change is the easiest thing in the world: just load your tool, select all the holes and just do it.
