Neville,

I am not aware of a Rowmark for laser and another for CNC use. Can anyone else answer with more assurance?

Laser is the preferred method though if you were really careful with your feeds and speeds and tested carefully you could use a CNC for the job. There is a CNC bit out there for doing ADA work as well if that is what you have the Rowmark for.

I think you will find a laser to be wayyyyyy faster engraving Rowmark than a CNC. Seemed like there have been some threads on this within this last year in both the laser and the CNC forums of SMC. A quick search will dig them up for you.
