The analog thermometers are typically repeatable to <1&#37;... you need better than that?!

<chuckle> I have no idea what I was thinking when I wrote that ;-) Thermometer... turkey thermometer!

"Turkey baster" style analog power meters are in the $200+ range, but the cheapest digital meter starts around $800. You can rent the digital meters for around $100.

The higher wattage lasers are typically water-cooled. I believe the higher-end FireStar units by Epilog have water cooling as an option...

:nono: I have no problems etching leaded glass. In this case I'm willing to bet there was simply a major flaw in the glass, and the laser heated it up until it gave way.

Try freezing the sheet first to cut down on edge melt.

<slap forehead> Should have caught that one... (wedge)

Minor correction... 500 dpi is 0.002" between pulses, not 0.050".

I see no issue with engraving that large wine pitcher. Rotate the letters 180 degrees and slightly the pitcher towards the front of the machine. The pitcher is oriented with the portion to be...

Then go buy it... if you're looking for warez here you're in the wrong place.

DD,

Send me an email and a description of what you're looking to do (part size, image type, etc.). The pieces do not need to be hard anodized as they're not wear items (like an engine valve...

That's obviously laser-engraved anodized aluminum (CO2 would have no problem with that), and the level of detail shown is no problem at all. I've done quite a bit of anodized aluminum and it hold a...

Hundreds of watts, at a minimum... and you're still going to get a heavily charred edge. CF is best cut with a waterjet.

Spoken like a true rival laser company... moron.

The kerf should be the same regardless of where it is on the item being cut... if not, the beam needs an alignment. The kerf for 1/4" material should also be very minimal... the beam has an...

You're not going to get that kind of resolution with a CO2 laser, if that's your plan... even a YAG would have a difficult time getting there without some very high quality optics.

I don't see why...

If you plan on doing acrylic, furnace filters aren't going to cut it. Those are some nasty, toxic fumes coming off of that plastic, so a charcoal bed is a necessity. Unless you're venting to the...

A lot...

Hey guys, this forum is NOT the place to be discussing company issues. If you have a problem with another company, call the police and file a report, but unless we're able to hear both sides of the...

You supply RF sealed CO2 tubes with a low-voltage, high-amperage power... figure in the range of 45-50V (SS lasers are usually a few volts, unless placed in series) @ 5-20A (depends on laser power,...

Nearly two years later?!

Have you considered subbing the work out to a laser owner who can hit the ground running with this project? It would be a lot cheaper in the short run, as well as give you a chance to gauge the...

You say "only with SS and...", but does that include aluminum, as well? Could be flashback. if you haven't done aluminum yet (since that would do the same). At that kind of power, a melted pool of...

Bob,

1/32" anything shouldn't be a problem for even a 25W machine. Do not turn off the venting cart to get it to cut... doing so will gum up the lens and mirrors with smoke and then you'll be...

I'm trying to imagine how many glasses you'd have to mark to pay back a $10k machine... :confused:

Ouch! Purpleheart? It's one of the more difficult woods to carve, so yes, it can be the wood. It's a heavy resin wood, so it's difficult to engrave without setting on fire (this is where air...

Multiple passes are going to help, but ideally you would be using air assist to keep flaming down. Also consider masking your wood with some painter's tape (or again, ideally with sign transfer...

It's a US company using Chinese glass tubes... a relatively inexpensive way to go. I don't know what software they use to control it, but their prices for replacement tubes and power supplies are...

SOMEONE has to have an interest in this... so many people picking them up these days

Disregarding the fact that the website is nothing but a placeholder (zero content), any machine that large for such a low price is guaranteed to be a Chinese machine with a glass tube. Take that for...
