Re: LASER ALIGNMENT

that's the idea. do a few test squares, check each edge. it will show if you beam is not straight too. I.E. if the bevel is more one side than the other.
lasers are sort of machine dependent, so any advice, is just a suggestion. see what works best with your machine.

Re: LASER ALIGNMENT

the laser beam focus is cone shaped, coming to a point at the focal point and then spreading out again after that.
try getting the focal point half way through the material, or use a longer focal length lens, or both

Re: Pricing

Re: Vinyl records

yes, and yes !

the laser will cut them, but it will give off fumes that are poisonous to you, and corrosive to your machine !

So, I wouldn't ;)

What's the flow rate on yours Dave ?

these have 10l/M .. which doesn't seem like much ?

Re: Shadow when cutting

My 1st guess would be final mirror to nozzel .. i.e. reflecting of the side of the nozzel.
