I've been looking at fiber laser engravers as they seem to be able to engrave finer detail than I can achieve with a high speed spindle and they have pretty reasonable prices for say a 30W machine.
However, the software that typically comes with them seems to cause users a lot of issues for rotary engraving, never mind full 4 or 5 axis work.
So, I'm wondering how feasible it would be to attach a fiber laser source with simple fixed focus optics onto one of my existing cnc machines similar to how many users have done using a diode laser ?
Are there any particular issues with doing this or in controlling a fiber laser source ?

There an example module here which might be a suitable laser source;

I've found just one laser module designed for fitting to an existing cnc machine, however it seems a little underpowered with a relatively large spot size, but it's still interesting as a concept;
