I have a looping question

Where to start…. I have been programming for about a year. I am not too much of a noob but I do not have any one to really turn too and ask for help (besides you guys and gals). So I have been playing around with my cmm, making a program then making a loop program out of that…. Now I have ran into problems doing this.

-first problem is If I stop the program in the middle of the loop, pcdmis thinks that the current piece whether it be 2,3,4,5,6 is the first piece to start on. I noticed that the actual coordinates on features are off and stuck. Why is that?

-after avoiding that, my Theo’s keep changing on me. I do not have CAD models so I have to change my Theo’s manually. After running the program they always keep changing. Any way to stop that?

-I guess I am just asking someone to take a look over what I have, I need some senior programmers to teach this young buck some knowledge please here is a picture of my set-up and some code … any advice will help and I am not afraid to take criticism

p.s. I left my manual alignment to show y’all how its changing up on me.

TO help ensure that your theo/noms do not change, you MUST have is an alignment that locks all 6 DOF as a single alignment. The lack of this has been proven by TECH support to be ONE reason for changing theos/nominals in programs. (are there more, who knows, but this one HAS been proven).

How you go about getting there is up to you.

And, how you get there will depend on what you are working with.

If your part/fixture sits 'flat' on the machine, then there is no reason for your manual (rough, first, whatever) alignment NOT to be measured all in MCS, plane, line, line, circle, all can be measured in MCS without a problem.

OR, if your part/fixture does NOT sit flat on the table, you still do not need 'extra' alignments since your lines & circles can be measured in the plane of the measured plane, it's been in the software since V3.7 at least. Newer version allow you to select the measured plane as the 'workplane', in V3.7, you have to toggle it in the feature in the edit window, but it is there!

So, plane, line, line, intersection point, then make the alignment, level, rotate, x origin, y origin, z origin, then any axis offsets needed.

THEN, do it all again in DCC mode to the manual/rough alignment, and I would again do all 6 DOF in that alignment. Done and ready to go.

Thank you MAtt, that is why I do 1 Man. ALIGN and 1 DCC.
