    ... Christmas is over, we're heading for Easter -- but here's something for next Christmas ... scanned a "Brussels lace" window tag from my wife and lasered it (scaled down) from a 0.2mm aluminum card:

    ... got an request from a former customer - but now another laser, so first tried whether I get similar results with it -- it's a 30Watt fiberlaser (instead of the previous 20Watt), but in the range below 40kHz it can't perform this special "super-hot" mode ... so with other settings also different results ... but works too

    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.

    ... tried "deep engraving" in slate today -- here on 100x100mm slate tiles - left 1 pass, right 20x (just under 15 minutes):

    ... for an (ex-) customer request for yesterday I was "forced" to extend my fiber laser by an additional "endless" X-axis for engraving punching strips (have lasered approx. 30m).

    The stepper driver can be seen in the rear compartment at the bottom left - for the time being I fixed it "provisionally" to the aluminum plate with double-sided tape (will probably stay in forever ).


    So far, with two manual stops, I've only been able to cut and engrave up to the size of the small 150mm hooked liner - but I would have liked to be able to cut-engrave the 300mm steel liner as well.


    Then I searched my basement for free linear axes -- the one in the back has 300mm travel, the long spindle 500mm - I'll test it next time
