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.

I think the main problem for me is 1.) I need to learn really fast (super small aerospace company with not many employees/management unwilling to spend lots of money, so I have to figure things out on my own time/learn on my own). 2.) I come from a background more on the side of Basic programming and stuff like that. I *think* that I am describing the wrong thing/ looping won't work for me. The reason is that because it is shifting the alignments/I need more precision than what looping is doing. I am holding Total Positioning tolerances of .010 TP and using a fixturing plate on my CMM without ground pins. With the ground pins this should all be working/way more close. My theory (well, not really theory, because I can see that the alignment is shifting on the second/third/whatever number part) is that using looping doesn't adjust the alignment at all on the parts. It just drives off of the first parts alignment, and then I am shifting the loop by -11.5" in Y. It does a DCC on the second part, sure. But then the first parts data is being driven off the 2nd parts alignment coordinates. The Y's are perfect, they aren't messing up because I told the computer to go exactly -11.5 inches in Y...BUT the X's are shifting/I'm getting really screwy TP because the X's aren't going back in the same place every time. I don't have ground pins, I'm just using a washer bottomed hex head screw (it's got a round bit near the table, but can be screwed in with a socket wrench). These bolts aren't good enough for the looping pattern, and the looping just doesn't account for the 1st and 2nd parts actual positions. If it created an Alignment 1 for part 1, and an alignment 1.2 for part 2 for example, it would work. But each part is sharing an alignment. That's why I'm asking if anybody has used Variables/if and if end statements, and just shifting the alignment down -11.5 in Y because that would be much easier I think. I *could* just write it out....like copy and paste my DCC alignments, and then create a new alignment for each part on the table and shift it, but that is going to take a lot of tweaking and a much longer program. I wanted to get back into the swing of using logic statements. I am really sorry, I've probably confused the heck out of everyone on this forum. I'm going to go back and answer each persons comment, I am so sorry for being rude, but I am just desperate to learn as much as I can as fast as I can.
