I created a CSV file with two columns and 18 rows. In Lightburn I created a square and added text within the square with %0 on line1 and %1 on line 2 and set the offset to 1. I associated the variables with the CSV file and made a 3x3 array of the square and text. I set the auto advance to 9.
All worked perfect except the very last square did not put anything in %1. Possible bug.
Thank you berainlb, that did the trick. My offset was set to 0 for line 1 but it was set to 1 for line 2 which I failed to notice. Lightburn software always does what you ask of it, just gotta provide proper instructions!
