Default Pulled the trigger

We were starting to look at laser engravers ($8K for an Epilog?!!?!?) just a week ago when this thread started. Based on the comments up to this point, we also pulled the trigger on the 1W version. When it does show up, I will show some results on pens that we engrave to help add to the knowledge.

You sure looked at both ends of the spectrum! 40 watts versus 1, bench top versus being able to hold in one hand, focussing distance lens vs looking at a dot, etc.....

No kidding... After falling off my chair when I found the price of the Epilog , I was happy to see the other end of the spectrum.

We were looking at the Epilog for some other non-pen projects, but at that cost, we still couldn't justify the cost of it. For now, we are going to stick to the pens and look to expand later...

As for focusing the laser, I have had mixed results. I pretty much eye ball the precision. Text seems to engrave better than images. A wider pen, like a Sierra, has more surface to work with. I was surprised at how close I could get to the edges before the detail was lost.
Keith, thanks, that is exactly the sort of info I was looking for! Please, do, post some pix when you have the chance. Are you engraving in CA covered wood, Acrylic, both? Text is pretty much what I'm interested in.

PS: Could one engrave on bare wood, then apply the finish?
I did my initial testing on unfinished unturned blanks, just to see the level of details I could get and to get a feel for the software.

My first official engraving was on a friction polish finished pen (gearshift), but it didn't look like the lazer liked the finish as the engraving wasn't as solid as I had hoped for. I believe it is because of the reflective properties of the finish. you can't engrave shiny materials as the laser is either bounced away or refracted further, thus impacting the intensity of the focal point.

That's pretty much what I am expecting. I had sort of planned to do the engraving prior to finishing and see how that works. I also envision personalizing wood pen boxes, etc.

Forked over the $8.00 for expedited shipping, so hope to have it in 10-12 days (I've dealt with Gearbest.com before--expedited 10-12 days, free shipping 25-30 days).

Must be an issue with the incredibly low power, or a poor focus. No issues with finish on a 25 watt machine. I can get a little haze around the engraving, but a little rubbing alcohol takes it right off.

Mike, when you get this bad boy up and running, I would LOVE to take a drive to Fairfield to see this in action!

Here are some photos of some of the engraving I did on a Euro style twist pen. The pen is over a year old and was originally finished with friction polish. Sorry for the fuzzy pictures, I just took them at my desk at work. From L to R: Dr Who, Superheroes, Military, more Military, over all view.

I have other pens at home that I practiced on, plus an un-turned blank with various fonts used.

As you can see, the smaller the image, the less detail you can get...but I believe there is some settings in the software program that can change that, but there really isn't a manual.

If these photos should go somewhere else, let me know. Wasn't sure where to put them.

Keith, for the modest expenditure, I think those look great. Thanks for sharing!

Looks more successful with lettering than images in that scale.
