This should be simple and straight-forward, and would be covered in a tutorial which I’ve always meant to create: engraving your serial number tag.
I may have the beginnings of that tutorial somewhere, and if not, it’s simple enough and I’ll see what I can work up when I have a chance — unfortunately, I’m slammed at work (have to finish CRXs on a book in time for the proofreader to have it done by the end of the month in addition to normal work).
The problem with doing this in Carbide Create is that it re-sizes the text as it is re-keyed / entered, so you may have to fiddle with the settings, and it doesn’t have the kind of typographic control that I demand (one of the reasons I wound up learning to use TeX was that Quark XPress and other early DTP apps didn’t afford adequate typographic controls — one of the reasons I continue to use it is Adobe InDesign doesn’t afford adequate long document tools).
I think you could just adapt the techniques from the photo tools tutorial: http://www.shapeoko.com/wiki/index.php/Carbide_Create_Photo_Tracing (just replace the tools photo with an image of the coin) and the nascent inlay tutorial: http://www.shapeoko.com/wiki/index.php/Carbide_Create_V-carving_(advanced) — just set the text and apply the inlay option to that — that would just leave workholding @ApolloCrowe has done a number of things which do this in ways which could be adapted, and has done some coin modifications.
The balance of this post is intended for posterity should someone need to do production-level automated work in large quantities — skip it for now.
My inclination here would be to set this up as an automated typesetting job using a tool such as lualatex:
- provide CSV of text for customization — this w/ a customized typesetting routine would create a .pdf
- use Inkscape in a command-line form to union paths as needed and export to a .svg
- find some CAM app which was scriptable and load the SVG files into it, export G-code files
- make a fixture for the machine which will hold an array of coins
- concatenate the G-code files in a step-and-repeat and send them all to the machine
If you don’t have a sufficient quantity of jobs to do that, and if F-engrave affords adequate typographic controls for your needs, then it should work as well as Carbide Create, but with an interface which might suit your needs a bit better (copy-paste from a text file):
The problem with using Carbide Create for this is it’s a graphic program which doesn’t seem amenable to scripting (if it could be Applescripted this could all be quite easy on a Mac — I really wish Windows Powershell had the kind of direct app integration as Applescript does).
