Hi Dan,

Glad you liked the video. Sadly I can never do high quality because my web host doesn't like me posting large files and I haven't yet mastered YouTube 

That's true speed but the video is compressed down to 3Mb so there are probably a lot of frames missing and it perhaps looks faster than it really is. The X Axis feedrate is 4500mm/min but because of the combined mass of my X and Z the acceleration/deceleration is set low so the axis only just reaches around 4000 at the centre of it's travel on this 90mm diameter piece.
The one in the video is wood, it's Obechi and yes I have a good extractor system, this is one big essential for laser work.    (the near neighbors haven't complained yet but if they do then I will have to fit the HEPA filters etc uggg).

That looks awesome Tweakie. It would be neat to see that being made. (hint hint, nudge nudge)

Here you go Sam - It's a bit like watching paint dry    (ignore the intro spelling mistake) . http://www.cooperman.talktalk.net/Aztec2.wmv

Music is good though.

Sounds silly but are you looking at the tool radius as being your rounded corners ?

Hi Sam,

There is quite a lot of smoke and debris with raster scan and I don't think a video would be too interesting but I will give it a go. In the meantime here it is half done

Both X and Y are 16mm dia. x 5mm pitch pre-loaded (twin ball circuits) not certain but I believe they are from NSK (Japan) same as linear rails.

Hi Amir,

No I haven't built another machine (yet  ).
Because I do not have any cutter torque requirements, when using the laser, I can drive my X Axis right up to my G0 rapids feedrate and still get 100% reliability.

Hi Guys,

An Aztec calendar, laser cut into Traffolite (engraving laminate) using the Mach3 impact engraving plugin. CO2 Lasers seem to like hard stuff and it makes quite a noise when it chews into this Formica like surface. The image is 90mm diameter and I used a stepover of 0.1mm and feedrate of 4500mm/min (took around 10 minutes to complete).
