1. This is just an old gash piece of MDF, 500 x 500 x 6 mm in size.

    It's a good example *because* it is an old piece of crap, because it shows worst case scenarios, use new materials and the finished product results are accordingly better. Yes we know the power is set way too high for the speed, hence the flames, and possibly too little air flow too, but as I said, this is a worst case scenario demo piece, not a showcase piece for the sort of thing we would do for a paying customer, as no paying customer is going to turn up with damp MDF from a scrap bin...>;*)

    WE at Exeter Laser (exeter-laser.co.uk) choose Vimeo because unlike YouTube it is all high quality, and we *want* you to see everything.... nor do we drown out the original sound track with crap music to mask out the horrible grinding machine noises you get with cheap or poorly maintained equipment, we want you to have the laser operator experience.

  2. Just a quickie showing the first coolant fill

  3. This is 10 mm acrylic. I guess we're pushing the limits for a 2.5" focal length lens, should be using 4", but we are still at the stage of testing the machine and getting to know it.

    Hence this (and the butterly) 10 mm acrylic cut was done at a very sedate 1 mm/sec and 50 watts, and I have to say, the cut edge itself is excellent. I'm very pleased by this as I was going for quality and not speed, or not even trying to see how much faster it could go before quality started dropping off, the reasoning being those tests are better done with a 4" focal length lens.

    Again, it's an old piece of acrylic lying around so the protective film had already been removed, so the corners aren't quite what they could be

  4. Like the mud flap girl, this is done in 10 mm acrylic at a very sedate speed as we are still in testing and calibration phase, the edges are excellent and the raster engraving on the right wing is excellent, but I screwed up with the feed speed for the vector engraving on the left wing, it is there, just, but the camera basically doesn't show it.

  5. Just chopping some 20 mm high letters into 6 mm MDF

    This video was mainly done to show the difference, even when using the same gash MDF, when you ramp up the air assist, still 50 watts @ 5 mm/sec same as the previous one, but with the air assist on higher a much cleaner top surface and no flaming. No great care was taken with focus because again it's just some gash MDF and the real purpose is to contrast the air assist on a higher setting and nothing else changed, vs the MDF pattern video.

    Nice display of a serif font being cut, and leaving only tiny bridges in the donor material, highlighting the accuracy and versatility of a laser
