New to looping

[Ken379128]

I have tried looping for the 1st time today. I do a manual align. then just before I start dcc I assign C3 as an input then my dcc align then ask the operator to input how many pieces to run the affore mentioned C3 value then

V1 LOOP/START, ID = YES, NUMBER = C3.INPUT, START =1, SKIP = ,
OFFSET: XAXIS = 0, YAXIS = 25.364, ZAXIS =0, ANGLE = 0

Then I measure my features which runs fine on the 1st piece but when it is suppose to go to the next one it stops and will not goto the next piece. I checked out the F1 on looping but zip any Ideas. I want to do 4 pieces in the y axis direction.

Thanks for any help

p.s. global image 3.7 mr2

Perhaps you can assign C1.INPUT to a variable and use the variable in the number property. I've done it with variables and it works but it seems like your way should too.

Just making sure the LOOP command is marked for execute. I've fogotten to do that in the past.

[Ken379128]

C3 input is a number entered on the amount of pieces I want checked up to 4. I am using previously written programs as a guide and as far as I know it is all the same I cannot see a difference. I have marked the program, of course if I get time tomorrow I will try again just to make sure these things were done and I did not miss anything.

Here is a bit of code I wrote that I paste into my programs when I need to loop. It doesn't specify how many parts you want to measure, it just asks if you want to measure another until you say no. Put your measurement code between the "begin measurement" and "end measurement" comments.


Let me know how this works for you as I'm pretty new at this too...

Silly question time, got an end loop command in there?

Understanding that I believe your code should work. You could try retyping the C3.INPUT in the number property and see if PCDMIS picks it up. If not assign it to a variable like so

C3         =COMMENT/INPUT,NO,"ENTER THE NUMBER OF PARTS TO CHECK"
           ASSIGN/LOOP_COUNT = C3.INPUT
V1 LOOP/START, ID = YES, NUMBER = LOOP_COUNT, START =1, SKIP = ,
OFFSET: XAXIS = 0, YAXIS = 25.364, ZAXIS =0, ANGLE = 0

Here is another example from a program I use regularly to check a random number of parts. This is at the end of my program. The program will keep looping as long as you want. I put the notice to change parts in because operators have clicked "yes" w/o changing parts and screwed up. I also put in a second part to choose between printing and not printing a report. The reason being checks during setup to tell setup operators where the part is but do not need documentation.

Maybe this will help.

C1 =COMMENT/YESNO,ARE YOU CHECKING ANOTHER PART?
,
,IF YES LOAD PART BEFORE CLICKING "YES"
IF/C1.INPUT=="YES"
GOTO/START
END_IF/
IF/C1.INPUT=="NO"
GOTO/END
END_IF/
END =LABEL/
C2 =COMMENT/YESNO,PRINT REPORT?
IF/C2.INPUT=="YES"
GOTO/PRINT
END_IF/
IF/C2.INPUT=="NO"
GOTO/NO_PRINT
END_IF/
PRINT =LABEL/
PRINT/REPORT,TO_FILE=OFF,AUTO=1,$
TO_PRINTER=ON,DRAFTMODE=OFF,$
PREVIOUS_RUNS=DELETE_INSTANCES
NO_PRINT =LABEL/

Ken,

The code you are using should work, and in my opinion is the best and most simple of the looping options to use where offsets are concerned. I did notice however that your sig says that you are using 3.7MR2. Perhaps you want to try this loop in an older version or even go up to 3.7 MR3, as I heard alot of discussion with the variable style loop function having issues in MR2 when I was in my Advanced class.

Just a thought. Hope you get er done!

[BSchwark]

Did you put an "Loop/End" at the end of your program?

I didn't get an answer when I asked that question, I hope you do, so simple but it could be the problem

Why is the LOOP/END a sepparate insert command anyway? Intellisense adds an END/IF and END/WHILE and others to multi line code. Why is LOOP/END a separate action required by the programmer? It makes sense to me to just have it inserted at the same time as the loop block.

Yup, you're right, but if you want it to work you gotta do it the Demons way. Try it, it'll work.

That the way it was done in Avail and MM4. Old habits are hard to break?

It used to be in VB you'd had to indent nested sub routines (and other commands) if you wanted them to stand out. Now you don't. Minor gripe, but it could be changed.
