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.

One more thing NinjaBadger before I go to bed. I realize that much of my failure to comprehend what is being told to me is that I'm too used to translating my old knowledge of programming language or cad/cam use. I get more of the theory of what y'all are talking about compared to actually doing it in the program. For example, I understand the concept of loops, loop counters, offsets for x,y,z in coordinates, labels, subroutines, all that jazz. I've used it in different methods with BASIC or cad/cam, and I guess I'm trying to describe what I want without *knowing* how to do it in PC-Dmis. For me it's the little things of PC-DMIS that I wasn't taught, like each alignment needs to recall the last one. Or the Master/Main probe. The person that helps me in person every now and then from a friendly nearby company: he doesn't even use a Main/Master probe, and they are an aerospace company of around 25 people and inspects thousands of parts every year. So, I get this information from him, and he's helped me out a LOT (for real, many weekends), and then I read online what y'all are writing about which is way more complicated: and obviously it's working for you. And I'm not saying he's wrong either. I'm not trying to insult anybody here if that's what anybody thinks. I'm more or less trying to be a sponge lol. Absorb everyone's data. That's what I was complaining about before with conflicting/misinformation. I don't think I've read much misinformation here, I was talking more about with my friend and the probe loading: he told me that Hexagon said every time you do a probe change even with the magnetic holders that you had to cal after. Every time. So, I wasn't going to risk it being a noob, and I was happy finding a new "trick". But then I come on here and the information is very much different. Usually when you are getting the same results from multiple places (this forum) it's more accurate than the other sources.
