Laser Upgrade

[dcrowder]

My router is pretty quick as it is using rack and pinion for the X and Y axis - I really dont want to have to buy another machine as I need the z-axis (I think) to achieve what I want to...

this video is what I'm looking to try...... https://www.youtube.com/watch?v=rUIrS3Ot1I4 I've got no doubt that my machine could go quicker than that too.

You could strap a laser diode to your machine and use the PICengrave software as shown in the video. Two things come to mind though: Extraction and air blast. MDF and wood, smoke when being etched, you will need to have a good extractor fan and some sort of hood. The air blast ensures the laser lens stays clean but also that your piece does not catch fire. All doable, just remember, do not stare into the laser with your one remaining eye :D

The impressive video of a 150w Co2 laser is worlds away of anything will be achieved by a 2-10w diode.

True, but CO2 lasers at 150W do not give good results when engraving at low intensity. For wood shading, I would go diode any day as you can greyscale with ease.
