debugging loops

[EmilySue]

Solution, thank you @louisd: Make sure all alignments in loop RECALL ACTIVE ALIGNMENT!!!



PCDMIS 2016 CAD++ Brown & Sharpe Chameleon, Renishaw controller

I don't know why the first block of code executes correctly, but the second block of code does not. (second block of code in first comment) The second block offsets my OD features by the entire 12 inches Y and 6 inches X that my loop indicates. I wonder if I'm just lucky so far with the first block of code, since I don't specifically call out all 6 DOF in every alignment inside my loop?

Update: I've tried locking down all 6 DOF, then resetting all feature origins to 0,0 and shelling the program. not having any better luck.

Try changing your alignments to "use active alignment", and end your loop with an alignment that calls the same features as the alignment at start of loop.
I don't see any loop/end commands. Be sure you have two in there, otherwise first loop executes and doesn't know where to go when it finishes running code without a loop/end command.

Use Active... UGH! I knew it was something silly! I know better than to forget that.

The recall alignment and loop ends are after the report commands, which I didn't copy (forgot there was relevant stuff down there)

[EmilySue]

This worked offline. Thank you so much! I'll post the solution in my OP once I run it on a table full of actual parts.

[louisd]

Also when I program in loops, I set loop counts at 1 until ready to release the routine (then set loop count to whatever's necessary for pallet and change file to read-only), that way all loop data remains displaying the first position's nominals.

[EmilySue]

I hadn't programmed a new loop in quite a while - just got to working on learning other things - and just flaked out. IF I have the alignments correct, I don't usually have a problem with the nominals changing on me, but that is a nice method!
