Took delivery on wednesday. included software loads easily on pc. Unit is sturdy though certainly not even close to industrial/commercial grade. you have to use the included software which doesnt do much for editing. Did two trials yesterday with two different engraving depths. Laser engages and follows protocol. Unfortunately absolutely no engraving happened. since there is no user support and just a basic manual - there Is no way to troubleshoot. Could be user error. Could be defective. Im new to engraving but not new to tech and troubleshooting. No luck. Could have spent the money much bettet than on my new paperweight

I am extremely surprised by the number of people commenting on this product, which makes me curious enough to ask here: would anyone be able to layout a quick recommendation for someone (me) who would be interested in very precisely etching away the anodized layer on titanium and/or aluminum? No engraving of the actual metal is necessary; looking to eat away the surface oxide back to bare titanium.

I do have full chem gear and plenty of sense regarding hazardous substances due to my proximity to some not-so-lovely things at work; however, I don't think using a chemical means to remove the layer will suit my needs. I'm looking to remove the layer extremely precisely and only in specific positions. I'm capable of g-code, and hence was hoping for a CNC laser solution (but the reflectance of the material and other factors make me wonder if lasers would work at all)
On another note, I very much appreciate the detail in your response regarding your methodology, and I might try it with a separate project if I find a suitable need.

Take a look at K40 (40w) imported laser engravers. That should have enough power for what you want to do, and not break the bank. There's a lot of material on the net, and they appear to be very hackable as well.
go to wish or best gear and you can get this engraver for 70 to $80 all day long. I have seen some pretty good deals on massdrop but this kind of disappoints me. Hope they can do better.

Only once for me. It was a kilt. It is awesome.
Fwiw I also got burned by wish. $30 wetvac came slightly broken and required me to purchase additional parts. Woulda been cheaper to shell out the $35-40 in big box stores for name brand.
AMZ has the "Leepra Purple" for a few bucks more, looks identical except that has twice as much power as this one.
Doesn't seem like a great deal.
you or they should show some actual laser engravings that the tool has made!

That they don't is kind of a red flag in my book. :-/
Sabbradical
agreed. they did it again. just got notified of another laser engraver listed on massdrop without any images of the engravings :/

I purchased this off of Amazon for $125 last September. I got it because it was inexpensive and had no base allowing me to engrave objects of any size. Everything about it is cheap, including the software - BUT it works with no hassle that I've found. It's simple.
Note that the included software does not work with vector graphics. The laser burns in a scan-line pattern from top to bottom of the image. It is also manual-focus so there is no functionality to adjust to curved surfaces. The laser does have some tolerance to the focal-burn distance so maybe a slight curve is possible. Also don't expect deep cuts. You can put an image on something, but don't expect a groove.
Also leather stinks.
If I set an ridicoulusly low speed, will it cut thin wood or plastic?
fischele
Theoretically, yes. Realistically, no. If you had some 1mm thick wood, it might be able to cut through it over multiple passes, but you'd have to manually adjust the focus for each pass, without moving the workpiece or the engraver. I don't know how many passes it would take, but the vast majority of people would not be able to get even a second pass without changing the relative position enough to screw it up.
I've done more than my fair share of research on decent, low-cost cutting lasers and came to the conclusion that it doesn't exist yet. You can either spend a fair bit into 4 digits on a decent laser cutter, or you can get one of the (~$400) 40W CO2 lasers from eBay and do a LOT of work to get it running and keep it running.
"Able to engrave wood, paper, plastic, leather, and more" does more include aluminum, steel or other hard metals?

Yep, I agree about things getting complicated. I kept half-heartedly hoping that this engraver would be able to engrave metal, if I somehow tried really hard... until I remembered how reflective metal is. I heard that some jewellery metals can't be laser-cut at all, because they reflect nearly 100% of the beam. Imagine you're melting metal with 1% of your laser's power, while the other 99% is reflecting back up... I enjoy danger, but let's give that one miss. It's getting into light sabre territory.

CNC engravers using rotary diamond wheels like those made by Roland would seem the best option for metal but they are even more expensive than laser engravers.
Will this engrave non flat materials? For example Pint glasses, RTIC mugs, wrenches etc?
GFuggit
To do non-flat, you would need a software synchronized rotating fixture. These are available for other laser systems, don't know about this one.
GFuggit
I don't think so, mainly because that would require high quality optics and some sort of auto-focus mechanism which this thing doesn't have.
You can get this for 80-100 bucks on ebay includin shipping

You should take that with a grain of salt. It's probably still a 1000mW laser.
Zuryan
So this one is actually...? :-) But, yeah.. I've been working on a project where we've been using dozens of 30mW laser diodes sourced at different times on eBay and they do vary a lot. I don't have enough experience with this vendor or massdrop to know what to expect, but I'd like to presume it will be as advertised.
Why is this only shielded on one side? This looks stupidly dangerous, unless you plan on providing protective eyewear for everyone who might happen to wander by.

I can see some advantage of not having a staging area, like engraving the top of a table or other large object. But yeah, you'd have to be real careful regarding your backing for burn-through cutting projects.

There are a lot of things I'd like to see on a laser engraver... and we can have them all. We just have to pay a lot more money.
