NEJE Laser Engraver Questions

[qquake]

Really? That's all there is to it? You just set the engraver on a table and the piece to be engraved under it? How do you keep the engraving straight on the pen? It seems to me that it wouldn't take much to engrave off kilter just a little, and ruin the pen.

And a 20w for $200? Really?

I have two if the 3.5watt (or 7w, i don't remember). They are a big improvement over the box version. I bought it fronm Nancy McIntyre...around that price.

 

[qquake]

Do they actually work? Will a 7w engrave wood and acrylic pens?

 

[bsshog40]

The 3.5w will engrave wood, leather, antler. Without a rotary, yes, you will need to make sure your pen is straight. The laser will do an area sweep to show you exactly where you will be engraving. It also has an adjustment so you can move it up, down, left or right before you start to engrave. Watch some videos. There's a bunch of them on youtube.

 

[qquake]

I've already watched several videos, but haven't found one with the information I need. I'm trying to decide if I can engrave my own pens, or if it would be an exercise in futility.

 

[qquake]

Okay, I've watched several more videos, and these are my observations.

1. I probably only need the 3500mw (3.5w).
2. I won't need a rotary jig for single lines of text.
3. Setup is super easy. Just set the pen on something that keeps it from moving. A small sand or bean bag maybe?

One thing I haven't seen is filling the engraving with paint. On acrylic pens, the engraving place I use engraves through a piece of masking tape. They fill the engraving with paint, then peel off the tape once it dries. I'm assuming I can do the same thing. Opinions?

 

[bsshog40]

The 3.5w doesn't really engrave that deep. With wood, you can have the laser do multiple burns of the same pattern and it will eventually get a little deeper. With multiple burns though, you want to make sure you DO NOT MOVE the pen at all. I have not engraved on acrylic, so I'm not sure how that would work. I did a little mica powder inlay on a pen but I had to engrave a few times to get the engraving deep enough to be able to fill the engraving with the powder. I'm sure the stronger lasers, 7w and 20w will burn deeper but I don't have one of those to try.

Nancy suggested Rub N Buff, but I've never tried that. I'm guessing you rub it into the engraving then wipe off the excess.

[qquake]

I just can't decide. It seems simple enough, at least for single lines of engraving. But what if I can't figure out the software? Or run into other unforseen problem(s)?

 

[SteveJ]

Although the 3.5W will allow you to engrave on pens without the need for a rotary jig, the higher powered lasers allow for far greater flexibility and options down the road. The software isn't too difficult to learn - and unforseen problems do occur. If you buy from Nancy (https://nmclasers.com/shop/) you will get pretty good service as well as someone who is willing to answer your questions. Also, the way they measure the wattage on the blue lasers is somewhat different than how they measure it on a CO2 laser. It is my understanding that a 20W blue diode laser doesn't produce the same cutting ability as a 20W CO2 laser.

Well, I pulled the trigger and ordered a 7w from Nancy (NMC Lasers). It was more expensive than other suppliers, but it will be worth it for the support. Plus, the other suppliers are all Chinese companies, and you never know if they can be trusted. I'm excited right now, I hope I don't end up frustrated...

Just remember, you will get frustrated at times but you've made a good choice. There is a learning curve but it is worth it to suck with it. The more you play with it the more comfortable it will become.

My wife does a lot of crafts using scrabble tile and is forever bring entire games home. I took a couple of the tile trays and use them as a trough to hold my blanks steady.

Any chance we could get an update?

I am looking at this model as well, but it is out of stock.

Rub n Buff is good to use for engraving. Get it from Hobby Lobby or Michaels, or other art supply. Comes in a small tube but lasts a long time.

I had forgotten about this thread. I love the engraver, and am having a lot of fun with it. But I haven't quite gotten engraving acrylic figured out. However, I'm doing pretty good with wood. I've also used it for other fun things like wood gift tags.

Here is one of the tags.

Steve a 20w diode (that's the input power) laser delivers less than 5w output power to the material. It is also a very different wavelength from the CO2 laser. A 20w CO2 is roughly 4x more powerful at the material. Blue diode will pass right thru optically clear material and burn what is behind it. CO2 wavelength is absorbed by clear, such as alumalite, and will etch it nicely. It will also vaporize our cast resins with a smooth sharp edge, unlike the melting of a diode laser. I hope that helps.
