Need help with Looping Program

[Harry_Nguyen]

Good morning All.

First of all, Thank you very much for all your help in adv.

I never write a program with looping. Customer just sent a fixture with 10 part on it.

5pcs on top row and 5pcs on the bottom row. And they are all 3.00 even space of all.

My question is where should I start to loop and where should I ended in the program.

If chance can you please post the Program code for sample. Please.

Again, Thank you so much for all your time.

I would start by programming one part entirely at first fixture position, unless your routine will require probe rotations.
Save that routine.
Then save as a new file.
After your initial DCC alignment of either the fixture or the first part (fixture preferred)... insert a loop/start command. Change quantity to 2 and change your offset value in y to 3. this will be the loop for your two rows of 5 parts.

Insert another loop/start command. change quantity to 5 and change your offset value in x to 5.
save again, making sure your loop/end commands are placed after dimensions and whatever data output you use.

Now, set that PRG file as read only and test at a super super slow speed, just to be sure it runs as intended.

Helpful Hints:
-Insert a Move/Clearplane at start and end of loop, as well as a recall of your fixture alignment at start and end of loop.
-If you need to make changes, be sure you reset your loop counts to 1 and execute prior to acting on changes.
-If you use move/increments, it's better than move/points for looped moves. they get weird when you change looped code.
-If you align, recall active alignments within loop routine, it helps make sure the recall align doesn't get hung up within the loop.

Run a quick example program something like ........

Loop1 x distance 3
Loop 2 y distance 3
generic circle
end loop
end loop

Check your graphics screen.

See if this creates pattern you need. If not, adjust values.

Thank you. I don't know where is my loop should be? can you post an example code?

Right at the beginning of MODE/DCC or somewhere shortly after that (if you have move points or comments or something).

Something to note. Your first loop will encompass the entire program (starting after MODE/DCC), your second loop will encompass the first loop.

The first loop will loop the program 4 times (original location then the 4 offset locations) then the second loop will offset the second loop to the next row of parts.

I don't have any examples handy so I quickly threw this together as an example. There are no features in it. I used operator comments to show what goes where.

Also, take a look at the help file and the core manual.

Thank you. I will going to test it out soon.
