Hi guys, I'm on the lookout for a relatively cheap (<$1000) laser engraver to do some engraving on parts. I've had a go at one of these which my mate bought http://www.ebay.com.au/itm/10W-Lase...179415&hash=item5b3d75e47a:g:fwgAAOSwRJ1ZoRgH I'm pretty happy with how it works except that there's no option too focus for different heights. I mainly need it for engraving anodised aluminium and occassionally SS. I want to use this until I can afford a more industrial machine, my current workload isn't too high so I believe these will cope well. Any suggestions?
