    ... and here also in/through spring steel -- https://www.youtube.com/watch?v=A_MN...ature=youtu.be

    - attached is the result - the stripe has 10mm height, cut from 0.25mm spring steel

    i was testing a new extraction / filter system on my fiber laser and it seemed appropriate to post here.

    suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.

    ... looks/sounds interesting!

    Which type of fiberlaser (power and PWM-range) and galvo? - mine sounds totally different

    it's a raycus source. 50W averaged power with a frequency range of 50-100khz.

    ... mine is a 30W from JPT, frequency range 1kHz - 600kHz (linear reduced power when from 30kHz down to 1kHz) -- the two last videos were made with 50kHz, so only the exhauster and some "hissing" from the laser audible ...

    ... the sound in the video is from the galvos? - mine are barely audible ...

    the sound is from the metal ablating. the galvos are quiet.

    ... hmmm ... didn't sound correct -- with 50kHz there should only be some "hissing" and maybe harmonics at 25 and 12.5 kHz only, not this "variance" with line-length as in your video ...

    ... you can test it by engraving the same file with power set to 5% or below, so there wouldn't be any ablation.
