Multiple O103 repeat [n] in a single file

I am using the O103 repeat[n] function to do some repetitive incremental moves. This works fine until I try to use a second O103 in the program. Then i get an error saying “error duplicate o-word o103.”

What am I doing wrong?

While you can call an o sub multiple times (same o number), but an o repeat command can only be used once in a g-code program. To do multiple repeat commands you will have to use a unique number for each repeat call that you use in a g-code program.

To do what I think you want to do I would suggest putting your repeat within an o sub, then call the o sub repeatedly throughout your g-code program.

Your suggestion to place the repeat into an o code would work for this particular program. But suppose I wanted to write a program with multiple repeats, each of which is different. How would I approach this? Will either of the other two looping commands (while/endwhile, do/while)let me create multiple loops in one program?

You can have multiple repeats in a program, but they each have to use a different o-number. Same with other o-commands.

Well!

Thank you for pointing that out. I'll try that.

If I may ask, what then is the purpose of the o-number?

For example here is an array repeat that will make rows and colums of some code using 2 repeat commands (one nested inside the other).
