Going to build a laser engraver...

I think the biggest factor would be which software you'll be using to generate your g-code. There are a few threads indicating the support may be on par with grbl etc, but it also seems to be a priority to fix any issues thats limiting the firmwares ability to work with lasers.
Maybe if you elaborate a little more details on your use case someone can give you some more accurate feedback.

One of the best software for hobbyist or pro laser is "Lightburn". They have demo, and they are fairly cheap, at $40 for the G-Code compatible version. https://lightburnsoftware.com
The point being, you can look at their output G-Code right now, if you wish, including getting a feeling for how they raster.
-
There are several users already running laser engravers with Duets. We have been in discussions with Lightburn and we have further development work planned in the near future to reduce the amount of GCode needed when doing raster engraving.

I`m working on a laser where I did plan to use a Duet 2 WiFi
Is there a software like LOightBurn that is compatible with RRFW today?
Or Should I start with an simple grbl controller and wait for RRFW support in LightBurn? -
RRF is already compatible with GCode generated by Lightburn. In fact, Lightburn has configuration options to generate a number of different styles of GCode.

Please do not ask me for Duet support via PM or email, use the forum

So I can run my Duet 2 WiFi with the latest RRFW 3 in combination with LightBurn ?I have a 5V PWM laser and plan to use one of the pwm outputs on the Duet 2 extension board

That's a good way to interface a laser with a TTL-compatible PWM input to the Duet 2.

Not full RRFW support yet? or is there news in the rrfw 3 that make it work with LightBurn?

How would I start setting up LightBurn? Do I choose Marlin or GRBL as a default?

I am mainly looking for engraving photographic images. On wooden panels and back of mirrors. If possible in greyscale, if not in a fine dithering.

I've added a post to that thread.

The Grbl (not LPC and not M3) profile seems to work quite OK.

Disregard my statement above - with further testing - it doesn't seem to play along.... - Let's wait for the firware update
