That's what I've got too, though not used it much since I got it about a year or so ago.

I might have to pick your brains on it sometime if that's ok?

Out of interest, which software do you use, Robo Master or Design Master...or indeed illustrator with the plugin...or something else entirely?

I am a CorelDraw man (hate illustrator). What I do is all my artwork in Corel. Images, bla bla bla. Then I create a contour around this in a different colour.

I then select and export the coloured contour as a DXF. Then make the contour transparent and export the rest as a WMF. The reason for making the contour transparent is that the wmf is the same size as the dxf (important).

Then in Robomaster, import DXF, set to X0,Y0. Insert the WMF, and set to the same dimensions and position as the dxf (sometimes Robomaster imports them as 10x10px). Because I set the wmf to the same size as the dxf (with the contour) they scale correctly.

Then it is a case of adding registration marks and seding to the cutter.

Easy peasy.
 
Oh yes, you did mention earlier in the thread that you use CorelDraw. I see, you are printing the stickers and contour cutting, I've done this a couple of times but I'm quite interested in doing some coloured vinyl cutting so am doing some design work in Robo Master and Design Master, though neither are particularly user-friendly...

What sheets do you use for the stickers, got any pointers for a good value supplier of decent A4 white vinyl sheets?
 
What is the res on say the balsa wood? Could you 'burn' an image of say a 300dpi scanned newspaper on to a bit of balsa? Or even onto a bit of heavy cartridge paper?(for some literal laser printing) Could make for some interesting B&W style photo prints if you output a halftoned image.

Hangon, can it even print rasterised graphics ?
 
Yeah - that's pretty neat. The possibilities are very interesting. You could make some nice art/pictures , puzzles, games just by etching wood in this way. How thick material can it take? inch or more ?

It can print rasters. The green bits here are a bitmap. I have it set to 500dpi at the moment. The control software does all the hard work in conversions from colour to mono bitmaps. It works just like a printer. The head moves back and forth burning with different powered pin spots of light.

I just swapped out the water pump, so waiting for all the air to dissapate through the tube. Then I need to re-align everything and I will do a test print/burn.

As for the max height of objects I think I can get things that are about 4" high in there (the bed is adjustable).

For ultimate coolness I am going to make a rotary bed. So i can engrave cylindrical things, like glasses and bottles :-)

Pinter, I'm wanting to make a custom cat flap and need the Perspex cutting for the swing door, is it a service you would consider?

Yup, I can do 3mm stuff easily, more with more passes. I have clear, opal, trans Orange, black and white here now. If you send me cdr (v12 or earlier) or a DXF (max size is 260x160cms) I can take a look for ya.

How much for 10 key rings?? similar size to the OCUK thing you did???

Again send me a dxf or CDR or even a bitmap of what you need, and we can work out a deal.

It will be cheap for forum members, as I am not really running a laser cutting service (yet) :-)

Mostly tube time and materials.
 
Been following this thread (you have the best threads) with great interest, and now you say you're planning on doing glasses and bottles!
Will be very interested in paying you some money to engrave a bottle. I home brew, so would love to have one engraved just so I can show it off to my friends :D
Can you be my new daddy?

Yup I plan to do some cylindrical things. I figure I can make a mount (need to find some rollers, any ideas?). I have some stepper motors. I can add a plug so the rotary attachment uses the Y motor pulses to rotate rather then move in the Y axis.

Then I can do all kind of cool engraving on stuff.

I am also looking for some 3mm birch int plywood. I have some speakers to make and a very strange idea for an iPod dock which I think will rock!

Still my favourite toy!

Thanks for the stars, we aim to please the internet with kittens and lasers :-)
 
Ok, Tried engraving a bitmap onto some balsa.

Turned out very well considering it would normally burn balsa easily.

Example of detail, the 'n' in Incredible is 1.8mm across!

Who wants their iPod lasered :-)

BTW photo does not do it justice, looks amazing in real life, I can even read the date which is minute!

Source image is here: http://www.fodey.com/static/images/preview_newspaper.jpg I scaled it down even smaller.

Ok, popped out to get some 3mm Ply, they had 1.5mm but that was 3x the price!

Did some tests, Ply is a bit tough to get through. They didn't know if it was int or ext ply. Ext ply has back glue which absorbs the laser light.

Anyhow I managed to output a box :-)

Did a clear acrylic one too. Still needs aligning a bit.

Very nice, finger joints can be a tad annoying making sure all line up :p I find it fairly easy now but the first few models I did made my head hurt!

Here's some of the things I've done recently:
