Wood is pretty easy to etch/cut as its capable of burning better than the foam (with low power lasers). White foam is not only reflective but also translucent so much of the power is lost. I have tried putting blue tape on the foam to cut it to help assist in cutting but the laser would cut the tape easily, and only slightly etch the foam.

With your powerful laser, you are concentrating the energy much more to initiate the "melting" of foam which makes it pretty easy to cut at lower powers than that of wood - I hope I am making sense.

Here is my low powered laser capable of burning paint to make my own electoronic circuits and even cutting ply but not foam:

OK ... I have looked at this on eBay often for Engraving - but never for cutting. Interesting.

I don't think that would be a deal !!!!  I have to say that it has saved me a ton of time and work ... not cheap but neither is my time !

All I want now is a machine with big enough bed to cut fuselages etc.

But back to thread ... I'm really pleased with results of the Wot4 .... she flies just as superb as before.

Here's a follow up day .... two videos (same flight but different camera angles ... )





Very pleased ... pity about the rough grass tripping her up at end ... but no damage.
