not as far as I'm aware (for either).

I've seen the Vectric Aspire trial version can map text onto a 3d surface, but that's a bit pricey.

I'd have thought that was more of a Cam operation than a front end op. ?

Yep, either will do it with the right code. Just height map the part using a probe, which should be easy if it's metal as you can use a pointy bit and the part as the switch, then you effectively need to apply that transformation to existing code, or import the pointlist into a CAD program as a surface and use that to generate the code. There's plenty of CAM programs which will do the latter.

I've made and engraved quite a few MotoX bike clutch casings. If it's just an engraving then Jonathans way is the best and easy enough to do. Depending on how curved dictates to how dense you need to probe and time taken, thou it's usually a 5min affair has your only needing the curvature not the whole shape etc and the surface area is small.

Also I have a USBCNC card to try but not got round to it yet has the machine I'd like to try it on isn't finished. Will let you know when I do but it won't be for awhile.

Hi Jazz,

Glad to hear someone else has done this, what software did you use? Software is yet another area that needs much reading, this CNC lark certainly keeps you busy, even without a machine!

Look forward to reading the posts on the USBCNC, will be good to know how it relates to Mach 3/EMC2, which do you use/prefer?

Cheers,
Geoff.

I use Rhino for 3D/2D Cad modelling.
Generate tool-paths using BobCAD-CAM for general engineering stuff like machining casing etc and Artcam for other stuff like engraving or signs etc.
Both will do Engraving thou Artcam does it better or should say has better tool-paths. BobCad does the engineering stuff better, again with tool-paths more suited to that type of job.
Both will project tool-paths onto curved surfaces.

Only use Mach3 and know it inside out and it works with great backup and tons of experienced users behind it on the very rare occasions I need help.

Thanks Jonathan,

I was wondering if using a tool and the case was possible, thanks for confirming that for me.

Still much reasearch to go software wise!

Cheers,
Geoff.
