Very easy to get up and running with this laser engraver / cnc machine. I initially bought it for the cnc capability which it handles really well. I have tried it mainly on softwoods but I have managed to engrave a sign into oak as well.
The laser is easily fitted. You just power it off, remove the drill motor from the z axis (remember to unplug it from the controller card), and put the laser module where the drill motor was (facing down, obviously). Plug the laser wires into the relevant places on the controller card and you're good to go.
Before you start engraving you will need to ensure that the laser is switched on (mine has a little switch on the laser module itself) otherwise nothing will be engraved. Be sure to wear the safety glasses - you only get one pair of eyes!
The software that comes with the kit is functional. If you want something better there are lots of programs which can help you out - just Google for laser controller software.
The laser worked really well engraving onto a variety of woods both soft and hard. It also works well on white tiles if you spray them with white paint first (white paint with a high zinc content seems to work the best).
Unfortunately I don't have any images readily available to show you, but I hope this brief review is helpful.
In short, if you're just wanting to dabble with cnc and laser engraving, then I highly recommend this kit. If you make it into a business you may want to invest in a larger co2 laser in the future, but this should give you a good start while you're learning the ropes.
