Hi galacticroot,

Nice project! If I knew perl, I'd help out.

As far as features go, everybody wants everything - the greedy ********!
I'd rather see someone start with the basics, get the...

Here's Entry #2...

A lil different, but I hope the notion behind it comes across

Ok, Here's my first entry!

Surprisingly, it actually looks nice for a splash screen.

Did I win yet? Did I win yet? Did I win yet?

So, where's the photos of your new baby? =)

Question...

On the commercial laser engravers I've seen, instead of having the Z axis on the gantry, they raise/lower the table itself to focus to the height of the workpiece.

It's hard to tell...

Good to hear there hasn't been any problems.

Do you know if they have 110/220VAC PSU's as well, or just 220VAC?

Well, here's my sticker submission.

The text and background gecko can easily be color changed or resized without any loss to resolution as the original artwork can be modified for use on screen or...

AH, cool...
What are you using?

Paul,

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

Jim...

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...

"...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...

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...

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...

Be sure to ask them about importing it into the USA as well as contact customs and FDA.

I heard that some lasers are not allowed to be imported into the US under certain cercumstances and what...

I can't even locate a url for the mfg, Do you have one?

You could try Corel Draw, as it's 'standard' for most engraving shops.

Jim...

I've been looking at the commercial laser engravers (universal / epilog), and they want way too much money for what they give you imo.

35 Watt CO2 with a 12" x 24" cutting area - $14,000 USD

The EPS... none at all, not even cast acrylic. Extruded acrylic will stink like crazy. So much so that you will WISH you were sprayed by a skunk just to make it smell better.

The only thing is...

The EPS (expanded poly styrene or Styrafoam) is not a problem at all, neither is acrylic, delrin, and a few others I can't think of off the top of my head.
ABS being a really nasty material to work...

Take this with a grain of salt...

Since December 2004, I have been looking to purchase a commercial (universal, epilog) laser engraver.

It has been a big learning curve it what it's...
