A quick bench test, just check it all works OK now that it has been assembled up.
Here, the laser was fired for a 1 second burst (pressing the trigger then camera shutter almost simultaneously) at a setting of 20.5% PWM which, according to the Synrad power graph is approx. 25% of the lasers output power. It makes an instant and satisfying 'pop' as the cardboard ignites.
This is the beam straight out of the laser (approx. 6 mm diameter) without any lens, when it has been focussed to a point the size of a pin prick (0.04 mm) it should be quite awesome.  ;D

Hi Buddy, it is called 'Mach1Lic.dat' and it is in the Mach3 folder. If you have really lost it then contact Scott and he will re-issue the license but you may have to specify the name or possible names you used when you purchased it.

Just something I tried during the holiday - as opposed to 'inlay' this is 'onlay' or laser marquetry.

This example is rubbish really because it was produced by cutting two identical images from different veneers and then transposing the parts. It has no allowance for tool radius offset so I have filled the kerf just to see the end result.
By thickening the outline of the original .dxf I should be able to produce two toolpaths (one for cutting on the outside of the line and one for cutting on the inside of the line) then, if I get it right, the parts should fit exactly with no visible kerf.  :-\
A lot more experimenting before I get it right but it is an interesting technique and eminently suited to lasers.

My Boss took an early lunch today and while the cat's away..........

It took two attempts to get the tool radius offset correct but once I got it right the parts do fit pretty well.

So is this laser cutting a negative and positive and you are switching the cutouts? I am not sure of what I am seeing and havent really followed the thread.
I want to die in my sleep like my grandfather, not like the passengers in the car! :-)

That's about it.  ;)

( I haven't shown all the leftover parts that are thrown away).

Thanks Terry, who knows, I could be stalling out at the craft fairs later on in the year.  ;D
