Wonderful.... well will see I'm ordering next week.

[ViperTX]

Paul, how much is this costing?

[cncadmin]

50watt and power supply 930.00 shipped if I bought that in the states it would be 2800.00 on up.

Heh... I'm sorry man, really dont' mean to scare ya!

I've been shopping around for lasers (new/used) myself, and been talking to a LOT of people, how much of that is true or not is unknown, but better to be safe than sorry.

I REALLY hope it goes well, cause I'll be placing an order myself!

The guy I'm dealling with is on the ball, and answers all emails, how can you beat the price.

"What FDA Can Do

FDA’s authority is over the manufacturers of laser products. These products must meet a federal standard for the amount of radiation they can emit and must be properly labeled. FDA is working to identify manufacturers of overpowered green laser pointers and other illegal laser products and will take action to prevent unsafe products from being sold in the United States. If illegal products are imported into the U.S., they may be refused entry, returned to the seller, or destroyed. "

So how does this guy get away with it http://www.emissiontechnologies.com/index.htm he buys them from the same guy.

Remember the days when there was swings in the park, and round abouts, etc. Remember the days when you could take a picture of your kids in the park without been viewed as a paedophile.

People tell us we live in a free society. Crap

jymmm, you may be right in what you post, but please dont tell us about it. The glass is half full, right?

Paul, Please delete this post in 24 hours

re-read it it's only for green laser

It's all in the wording...

The FDA website mentions sale to "general public", not to manufactures.
So I suspect it's the mfg's responsability to label/use devices correctly.

It also restricts medical lasers to licensed practitioners.
So, when does a laser become a "medical laser" ?!?!?!?!

Probably when it gets a FDA certification, I'd suspect.

So, when is it no longer a "medical laser"?
After it's been "salvaged" (scrapped for parts) maybe.



So, if/when you get a call from US Customs, when you order arrives, just be sure to measure your words properly if in question.

It's all about CYA

Read again...

"...and other illegal laser products "


"green lasers" are only mentioned I suspect due to the media proiganda.
There are CO2, Yag, Argon, UV, Diode, IR, and a whole lot more lasers out there
far more powerful than 'green' laser pointers.

Paul,
Could you explain how you take the laser beam from the tube, probably away of your machine, to the z axis?

Thanks,
Alex

The laser tube itself is stationary.

Special optical mirrors are used to "bounce" the beam around the table, then typically a lens is used to 'focus' the beam.

The principal is the same as using a magnifying lens when you were a kid to burn a leaf.

[cncadmin]

Yes the focusing lens come at different focal lenghts, the distance away from the work.

Paul,

Have you made any choices in optics and found any good sources yet?

Jim...

[cncadmin]

I already have my mirrors and lens.

[jymmm]

AH, cool...
What are you using?

[cncadmin]

3/4" focal length and gold mirrors, I got them off of ebay.

[aghobby]

Ok, but the axis are moving..How do you keep the beam in track with your moving optics?

[cncadmin]

The laser shoots down the X and picks up a mirror that shoots it down the Y. The beam is always in contact with the mirror shooting down the Y. See the pictures here - http://www.emissiontechnologies.com/xy.htm
