Just wondering, has anyone tried the back side of a mirror?  Would it burn the coating off and leave it just glass?  Would it reflect and burn the shop down?  Would it leave the areas black and maybe you could wash off the coating and get some really neat effects?  I emphasise back side here and that may be a no no.   Maybe it wont work with real mirrors but would with black paint on a piece of glass?

Doe - That is done on the back side of a mirror.

How do I check if I did not connect the motor cables incorrectly?

If the C10 is enabled then the motors will 'lock' at system power-up.

(If you have not connected the motors correctly there is a danger of damaging the 4030)

Pysiek,

I take it that you do have a good and stable (regulated) 5 Volt supply connected to your C10 ??

That is quite amazing Jeff - excellent work indeed.

I would try; Config / System Hotkeys - then set Z++ and Z-- to the keyboard keys of your choice.

Hi Craig,

Thanks for your suggestions / ideas, they really are much appreciated.

If you were to rerun the program several times does it etch into the tile deeper?

I don't know, possibly it would - but the secret is not to completely destroy the surface glaze, just to heat it, creating the micro fractures / melt which capture the carbon soot (if that's what it actually is).

Also wondered about applying rub-n-buff for an added effect. You could mask and color areas for effect.

I have tried rub'n'buff after etching and yes colours could be produced but rub'n'buff is easily removed with many different household solvents and the finished tile, although looking good would perhaps not be so durable (I doubt it would survive too many dishwasher cycles).

Others are currently experimenting with coloured enamelling powders and laser fusing these onto / into the tile surface (similar to my toner experiments shown earlier). So far, the results are not that spectacular but I think the idea has great promise and definitely needs further investigation.

Hi Craig,

I don’t know if this image helps because there is not really a dot pattern as such to see.

The tile was produced from an 8 bit image using the Impact / Laser plugin and this fires the laser at up to 12,500 times per second so with a feed-rate of just 3,500 mm/min most of the dots appear on top of one another (overlapping).

The marking is essentially carbon soot which has, for the most part, been integrated into the surface glaze. I still have some different samples outside in the weather and what little sunshine we have had lately - whilst others have now had many dishwasher cycles so I am thinking the marking is reasonably permanent.

The lasering process will certainly destroy the surface integrity of the glaze but tiles are not usually glazed on their edges and I doubt that grouting compound is totally moisture resistant. But, like most of my stuff, it is early days yet and time will tell.

Hi Pisagor,

I am sorry, but there is no kind way to say this - The Chinese TB6560 controller board is junk.
In my opinion, you are unlikely to get it to perform in a satisfactory manner and you would perhaps be best advised to cut your losses now and invest in a substantially higher quality product (such as the Gecko G540) which has proper support and documentation etc.

I have been asked to do a few laser’d tiles for a friend (non-commercial work).

Following a bit of experimentation, it was evident that pen and ink line drawings (which use hatching to create the illusion of shade) produce better results than the pencil sketch drawings and this is the result of one of the tests which I thought I would share.

(I should point out that I have no rights to use this image. It was solely used as a test and this tile was destroyed after the photo was taken).
