Brilliant work Hannu - that looks really great.

Pablo,

My apologies for linking Mayan and Aztec as though they are the same.

I was always (since school) told that this calendar was Aztec but I have since learned that the Mayans were the skilled builders / craftsmen and probably the true creators of this stone masterpiece.
Because nobody is completely sure of the origin Mayan (Aztec) seems to cover both possibilities.

The Mayans were a post-Aztec civilization, the calendar as depicted in the artwork in this forum is Aztec ( except that middle graphic, that has to be modern )This is a MESOAMERICAN calendar used by lots of civilizations. Here's a Wiki link for more info.

Hi Guys,

After breaking a couple of router bits in voids in the crap plywood I had been given to profile cut I have gained a bit of spare machine time to play with the laser whilst I wait for the new bits to arrive.
This image has been cut to FSE’s dimensions in Oak and is probably equal to their quality but as they refuse to put up a higher resolution image, despite my repeated requests, we will perhaps never really know.
I had not cut anything into Oak before and it was quite a learning experience. It requires about 30% less power than engraving laminate and is considerably less noisy (hard engraving laminate makes quite a racket when you start chewing into it with a laser) also, as Fantasy2 and others had suspected, the sharp corners char more readily than the flat surfaces and this has the effect of smoothing the contours of the image.
This example was cut with a vertical (Y Axis) stepover of 0.08mm and horizontal (Y Axis) feedrate of 4500mm per minute. The total time from loading the .BMP to completing the work was 19 minutes (not as fast as FSE but my X Axis also carries the Z Axis which usually holds a 3 Phase spindle router motor. This combined mass limits my acceleration / deceleration and maximum federate over such short distances – thus the extra time. If anyone is interested in the details of my machine there is the full build history and lots more junk on my website here http://www.cooperman.talktalk.net/ ).
Although I can continue to reduce the vertical stepover I think that any possible increase in resolution is probably outweighed by the increase in job completion time.
What do you Guys think – is this as good as the FSE example or should I cut another with smaller stepover ?. Like to know your views.

Looks good Tweakie.. Here is a photo of ours as well. its about 2.3 inches. Photo is a little blurry and I can try to get a better photo later.
This was done with our 40w machine table size of 23.6 x 11.8 " running lasercut 5.3
But if you look at that guys earlier post he said it was engraved on maple... now here he says its oak.

Tweakie,
You have a very informative web site, thank you for sharing!

I'm with diyengineer....I need a Laser......

Shame I don't sell lasers - got two potential customers here

Dean,

That etching on the tile is great, so much detail.

Maybe you should start selling them, and possibly kits haha

[ViperTX]

Tweakie,
From whom did you get your laser?

Thanks,
Paul

[Tweakie]

Hi Paul,

The various laser parts came from all over the world.
The tube, mirrors and mounts from USA ; the PSU from China ; the focus lens from Israel ; pump from Korea ; the linear slides and ballscrews were purchased in the UK but made in Japan. And so the list goes on - wonderful thing the internet

One final free advert for FSE.

I think you need a disclaimer on those 'ads' that these were not produced on the systems FSE sell or you could slap your 'Tweakie' tag on them instead.

Dean,

I've been fine - I hope you also !! Everything working just nice, except I had a little algae problem (due our warm and moisty summer weather) - I made some little mix of distilled water / algae killer / cooling liquid - since the water has been as bright as possible - no problems - ( thanks for the settings ! )

Best regards
Hannu

Hi Guys,
I've finished my first object with the CNC ( the CNC I've designed from scratch), welcomes any comments.
Thank you.

Very nice job Ztoti!

I remember the first time I ran it up on a 600mm x 600mm board it almost killed the PC running the cnc! It's a lot of processing to do that design, but yours came out really well!

If your self built machine can do that, you should be very pleased.

cheers, Ian
