Test of the Vertical Laser XL on cutting a 1/2" thick plexiglass using a 2" focal lens at various speeds. the nozzle position is almost touching the face of the plexiglass, bringing the focus convergence well into the material.
One thought that I didn't add to the video is that the surface on which I placed the Plexiglas doesn't allow for the material to be evacuated like a honeycomb material would. I may do further testing to see if a honeycomb or other "breathable" support would allow more efficient cuts.
So, what do you all think of the tests. Is it what you expected? Is there a variation that you would like me to try? Let me know in these comments. Thanks!!!
Not sure if you have done further test's but I cut 10mm at %66 power and 4mms on my 50watt Ebay blue machine on a raised pinbed. It is a clean cut underneath because of that.
seen sumtin a while back with a professional focal point determination
they used a thick block (like the 1/2 inch turned sideways ) and shot the laser at it for an x amount of time
the focal point was the biggest bulb in the line the laser cutted in the plexy
Interesting. I might try that. Love how you spelled something "sumtin". It's the way we say it in Jamaica.
im dutch i learned english from reading a lot , picked stuff up from just about everywhere
That's the best way!!
it seems like the "kerf is wider near the top.. so I guess it wouldn't be perfectly square to teh surface?...How about a 4 inch focal lenght? Is it easy to get and install a different one on your machine?
Yes, I will be doing tests with the 3" and 4" focal length lenses after I exhaust all the tests for the 2". You are correct that the top seems to have a fillet where the top edge has a bit more melting going on, and it is angled towards the bottom. I think the angle is the actual cone of the lasing energy, but the fillet on the top I think is just a little more heat melting it.
We just bought a 130w. Do you know where to buy quality lens?
You could buy it from us at buildyourcnc.com. We have not tried our lenses with 130W however. If you have specifications, we can certainly find a supplier.
