I have just started using the machine and enjoyingit.

My challenge is to isolate the best materials and matching the machine to photograv.

1. In particular I enjoy engraving slate but I I am having difficulty getting adequate contrast unless the finished poroduct is fully and carefully illuminated. I am using the Black Granite setting in Photograv- this tends to give a dark image on slate and a very thin/ dark image on granite. My normal machine settings are 250mms and 20% power on slate- anything with more power wipes out the detail. At this level the detail can be very good but slightly dark. Increase net power and engraving is lighter- but detail is wiped out. Increasing bright/ levels in Corel also works but its slightly hit or miss.

2. I have no success- inadequate power- engraving ceramic tiles! Any ideas? Is there a laserable ceramic?

3. Wood is great- good contrast and fine detail.

4. Acrylic is excellent especially when lit at the base by LEDS.

5. I am not overimpressed with glass. Tendency to go negative unless lit very carefully.

Any ideas on different materials etc would be appreciated. Naturally, as I make some progress I will share with the Forum.

Thanks,

David

Suggestions would be most welcome.

Hi David,
Try wet paper on glass it gives a far better finish.
Try Thermark which is available in colours for ceramic and glass
Try their site for info.
