    Looks like fun, but those are the types of machines company's buy to do their own mass production laser engraving instead of coming to US for it -- They even brag that Smith & Wesson and Springfield Armory use their machines. While I could make great use of one of those, I'd never be able to afford one... even with my workload it would take a few years to hit break-even and actually start seeing a profit. My fiber covered it's cost within 6 months. The Yeti-type cups and whiskey flasks they're marking in 14 to 17 minutes, charging enough to cover that much engraving time is a hard sell, and most of those are 6 minutes work via Cermark...

    Yup, as much as I'd love an Austin Martin, the Mustang GT will have to do!

    Nice, Actually If a person were really good with electronics, steppers and controls, I'd bet this would really be something pretty easy to cobble up.
    But not me for sure. Think of turning the rotary into a flat, just long x step rather than turning rotary. This is all that is happening, at least in the video. Now add Y movement driven by controller, that's a different thing. (but that video didn't show that happening)

    Software would be a challenge. Good for a conveyor-belt application.

    force of habit-- and shows just how far down my 'yeah, right' ladder an ASTIN Martin is

    I had a guy from some laser outfit in Calyfornya call me a few months ago, quoted me 'about' $3500 to build a simple XY-gantry, with software, using my Triumph parts. Been waiting for him to call me back...

    I've toyed with the idea of picking up a 20w cheap Ebay fiber like mine and doing this myself; I have the two XT machines, the one is pretty much proprietary to one customer, which is ez enough to change. These machines, unlike most CNC's these days, has a moving spindle carriage, with about 2-3/4" inch of vertical travel. Add that to the 3-1/2" of spindle head travel, and that would give me a great range of focus. Mounting the scanhead to the spindle head would be a simple matter of cobbling together a bracket to hold the thing. Taking into account the space the scanhead would eat in the Y axis, I'd still have 24" of X travel and about 15" of Y travel. The main jobs I have in mind for this would be operator panels I currently do by C02, mostly text, and small graphics, meaning, it would be easy to piece together 'sections' that would fit within the 6" scanhead limits. Each section would have to be moved into position in EZcad, and then the machine moved to match. it would be 'manually operated' to be sure, but I'm already moving the same kinds of parts by hand manually, and aligning each section by redlighting. The XT table moves could be entered as a job requiring nothing more than pressing start & pause. The routine would be run 1st section/move 2nd section in position in EZcad/start-pause/run 2nd section/move 3rd section into position/ etc... I'm actually pretty certain the job sections can be setup in EZcad to change themselves, and using the 'flymark' function, the fiber could tell the XT when to move..

    If only I wasn't planning on semi-retirement in less than 2 years...
