... 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:

... I'm optimizing the setup for marking 150mm steel rulers (this is/was a forum action in "Peter's CNC-Ecke").


Here the video of the 2nd test -- [www.youtube.com]


And the results so far (the steel ruler is still from the last action):

... here a more actual video from laserengraving a hook-ruler -- [www.youtube.com]

It's maybe 10x faster with the 30Watt-fiberlaser than with the previous 20Watt.

And here the actual result too (in comparison to a common 300mm-steel ruler):

... marked some scales with a 30W-fiberlaser (request in/for the German forum "CNC-Ecke")

here the video with the 2m-scale - [www.youtube.com]

And with the 1m - [www.youtube.com]


The result (the 2m could be darker too):

... even better and more usable than a fiberlaser (bur more expensive too) is an UV-DPSS-Laser.

For a R&D-project I've ordered a 10Watt laser (had a 20W-type for a half a year for testing) and all the needed components - here an image of the temporary setup:




It's meant mainly for microfabrication with graphite and some other "R&D"-stuff ... but is pretty good with wood too
