I'd like to engrave a logo on a bicycle head tube before a frame building class in a couple weeks. Unfortunately I no longer have access to the CNC machines I used to work with and now have a Tormach 1100 available at a local tech shop.

I have read in the manual that I cannot use a G2/G3 on the rotary head, is that correct? If yes, then I'll have to somehow convert the arcs into segments and think perhaps Fusion 360 might accomplish this for me? Thoughts?

Take a look at cnc wrapper.

The website is down for the moment but I'm sure you can find it on another website.

Jeff, thanks for that tip! While the cncwrapper site is not available as you indicated, google turned up this freeware and it looks like it will meet my needs...

You might find GCode Ripper (G-Code Ripper) suitable for your project.

Kstrauss, thanks for that, seems to be a better solution as it handles the non-metric standard here in the backwaters of the US.

GCode Ripper looks VERY promising, however the graphic of what it produces is dubious, It's a logo and it should be a circle at the top, not compressed as it appears?

probably not thinking it through, but don't you just sub A for Y?
