G-code to engrave numbers on cylinders

UUUUUGGGGHHHH, It's working now. Sorry about that.

Has anyone expanded this to include letters as well as numbers. Seem like this could be a cool generic program to engrave serial numbers or other information on pens and such.

I think it would be difficult to modify this code to handle alphabetical characters as it relies on calculating and calling computed subroutines.
I guess it might be possible have subs for each ASCII code, but I don't know how one would pass the strings to the G-code.

I guess I envisioned a sub for each g code.

I could do this is fusion 360, but incrementing the serial number for each one seems better suited to a gcode program. There must be something like this out there already.

I am pretty sure that you could write a G-code sub to carve sequential alphanumeric strings as serial numbers.
I thought you wanted to carve arbitrary strings. In that scenario the hard part is passing the strings to the G-code.
