G-code to engrave numbers on cylinders

Andy you are my savior. All I need is Bolton Brass engraved on a 1/2" round piece of brass with a single letter or number below it. And I agree with BigJohnT, that is slick as hell. Please tell me you make money doing this......
I know I am late to this post, but where do I start with xza?

This might not be too hard, you only need a few extra letters (B,o,l,t,n,r,a,s)

But: The point of this routine was to generate the numbers on-the-fly for scale rings of various types (0-360, -180-180, 0-10. 0-25 etc)
For engraving the same words many times it is probably sensible just to use a CAM system like Fusion360 to create the G-code once :

If you want to use this G-code, then it might help to explain how it works.
Each number is created by joining points on two octagons. (generally). I worked out the coordinates of the required points, typed them in (probably in Excel) and then formed them in to the subroutines (again, probably using Excel, but it was quite a while ago)

This is the number 8
The factors #41 and #42 are used to scale in the A and X directions. Here are the points plotted in Excel:



You would Need to create the letters you need in the same way, and form them into a subroutine looking like the existing digits.
I would suggest using ASCII to name the subroutines:

B = 66
o = 111
l = 108
t = 116
n = 110
r = 114
a = 97
s = 115

I actively avoid making money from this. It's important to me to keep it a hobby.

I have modified the code to also do the tick marks.

Hi. This is almost what I was looking forimage missing /media/kunena/emoticons/smile.png. I need to make a cylindrical dial for a leadscrew with 1/8 inch move per rotation. So it would be 125 ticks, each 5th is slightly bigger, each 10th is bit more bigger. And numbers 0, 10, 20,...110, 120 beside 10th ticks. How I can modify your code?
BTW, other dials, 1/10" per rotation or even metric would very useful. 

Try just changing #<_inc> to 28.8 degrees (and see what the preview looks like)
That's 360 / 12.5 though it sounds a bit too large without testing, and I don't know what it will do at 120.
(Sorry, not at a LinuxCNC machine at the moment to test it)
