Cmmxyz: Nested loops video: General questions

[BIGWIG7]

I'm not great at loops.
1. When looping, what do you do to make sure each report is separate and individually labeled?

2. I'm attempting to loop a program which requires the operator to flip the part(s) upside down half way through the program. There are 3 parts on my new fixture. How do I know the report is generating correctly, connecting the first part UP with first part DOWN and so on....?
For clarity, my first loop checks 3 pcs UP, there is a pause, the operator turns the parts DOWN, then the machine goes back to the beginning and checks the same parts DOWN.
How do I know corresponding UP and DOWN parts will generate the matching report?

3. I've added my loops. When I try to run the part in offline, PCDMIS crashes. Any ideas? 2018 R1 CAD++ sp5






HI TREVOR!

[BIGWIG7]

[KIRBSTER269]

I've commented 7 times already, are you on a smoke break???????

[KIRBSTER269]

How many LOOP commands in there? Where is your LOOP end? "Where o where are you tonight? Why did you leave me here all alone?, I searched the world over and thought I found true love, you met another and PHHT!!! you were gone.

[KIRBSTER269]

How do you export the report? What's inside the LOOP, stays in the LOOP. If you use STATS, you put the STATS end right before the LOOP end. If you export it like PDF or Xcel, then you put Print Commands at the beginning and one at the end (inside the LOOP). One to KEEP instances and one to DELETE instances.

[KIRBSTER269]

Can you Post the code that your using? The LOOP and PRINT Commands or STATS or whatever. Don't really need the Program Code.

I export the report using standard method: SAVE/PRINT THE REPORT button in Report window
Not sure what the question is here?

[KIRBSTER269]

My apologies thought you were having problems with print exporting. So I guess my question is what are you trying to accomplish? You have lets say 3 parts you run all 3 up and you then run 3 parts down and you want to align results 1 with 1, 2 with 2, and 3 with 3?

[BIGWIG7]

yes.
if I loop the first half and loop the second half but then report everything at the end, will the report combine loop1x1 to loop2x1. loop 1x2 and loop 2x2, and so on?

[KIRBSTER269]

That might be tough to pull off. Be like adding pages in the middle of a book. I would think it could be done, by sending results to the very end of the program and grouping it there. I will mess around with it, and see if I can't come up with something.

[BIGWIG7]

ok kirbster I can't figure this out. I put the looping commands where I think I need them, I have moved the reporting features around so they are split into the two looping commands.

the software (2018 R2) crashes the instant I execute the program. why?

how do I post code over 10000 characters?

[BIGWIG7]

can you not have two loops in the same program if they don't overlap?

[KIRBSTER269]

You can have 2 Loops, one inside another or a loop and later in the program another loop. I have done both.

[BIGWIG7]

can the LOOP/END command be the very last line of code in the program?

[KIRBSTER269]

Sorry haven't gotten back here, got busy, LOOP/ END can be the last line

[BIGWIG7]

YA this is so bizarre.
I open my program.
add first loop,
simulate and execute in offline
simulate and execute 5x more in offline mode
add second loop
simulate and execute in offline
simulate and execute 5x more in offline mode

no problems

save program
save program and relabel so I can continue editing program

rerun program again with no changes otherthan change to program name

software crashes

open previously saved program that was running fine before.....

software crashes.

have to start all over again.

[vpt.se]

Can you provide the program here so others can test it (to see if it crashes)?

[BIGWIG7]

how do I do that?

[SABarber]

I don't know what relabel means but you can try the following to get past the cash.

There is a registry setting "Option", "SavePreviousInstances" which is defaulted to 1. This causes pcdmis to save all duplicated (looped) commands. It could be that the duplicated ones are not correctly re-attached.
Set this value to 0 while pcdmis is NOT running.

Run pcdmis.
Load the PRG in question.
File/Save As, give some other name.
This should save the file without any extra instances of the command.
File/Quit to close the PRG.
You can then try to load and execute the newly named PRG to see what happens.
The only difference is there are no extra instances to delete and try to reconnect properly internally.
Last execution mode of the report would also not display those commands since they do not exist yet.

Prior to v4.0, pcdmis never saved the duplicated command instances.
It is now on by default (registry setting). It is up to the user if they wish to perform this type of saving.

Just something to try to get past the crash.

[BIGWIG7]

Can someone please write me a quick Assignment that allows me to put a small title at the head of every looped report so that I can keep track of serial numbers?
but also needs to allow for a range.

for example first loop parts 1-9, next loop 10-19 and so on but put a title at the top of every looped report so I can track parts.

[BIGWIG7]

bump ttt

[sealevel]

BIGWIG7 -- It probably is not the way you wish to do it, but for looping programs, I would have a 'loop.rtp' report/header and in the header it had a cell for the serialized part. (1,2,3...etc)
I just liked it better than having it in the report with all the feature reporting.
But for your need (if I understand it) the variable is simply a counter.


multipart.PNG

Sorry. I probably shouldn't have included the "WHILE/ END_WHILE" stuff in there. A generic loop wasn't doing what I needed for that part family
But anyway, this should work for your 'regular' Loop.......

Put this in before the loop command:
ASSIGN/V7=0

Then put this after the loop command:

ASSIGN/V7=V7+1

COMMENT/REPT,
"Station "+V7
COMMENT/REPT,


((( Then here is where the reporting stuff goes......,)))

Obviously, you can change 'station' to 'part' or whatever you choose.... sorry for my extra code in there before!

[BIGWIG7]

good lord that looks complicated. I'll give it a shot but i'm pretty confident i'm not gonna get that one.

are your serial numbers sequential every time or will there instances where they might mix?

sequential ex 1,2,3,4,5,6

mix/random ex 14,21,36,A

[Sutharsan]

what is External alignment how to use

[acgarcia]

An external alignment saves the location of the tryhedron in a file. Open a new program, align to a part, and save the manual alignment or reappoint alignment to your computer and machine. Then you can open another new program and just recall your saved external alignment. You can go straight to dcc alignment without doing the manual alignment. Works great for part families.
