Need something that can engrave metal similar to electro etching. It's not cost effective nor easy to make stencils for one-of jobs. Currently using a high speed spindle and I've used a vibratory engraver in a CNC application.
I see a number of fiber laser diodes listed on Ebay. What would be ideal, and I don't know if such an animal exists, would be a laser device where the head was connected to the laser via fiber. The head would be mounted in place of the CNC spindle and you would drive the machine using regular CAM software using M codes and Z retracts to turn the laser on & off.
Is something like this possible and cost effective using surplus parts?
