I think I will buy the bigger version of this once I see what you guys like and dislike about the smaller model.

Default Re: $90 Laser Engraver Kit?

I've spent about 15 emails going back and forth with them, trying to get them to send me a copy of the software.

They send strange links, that don't work, then they claim they attach files, but send emails without attachments. I'm growing very frustrated.

Sounds about right, probably "Drop Shipped" to you so they do random stuff to shut you up.
So have you received the unit yet? or are you waiting on unit and software?

Default Re: $90 Laser Engraver Kit?

This one on eBay claims to have a 500mW laser and supports "gray scale printing function" for $189. Seems a little odd to me to see what look like screws sticking out of the laser housing, as if it wasn't completely installed, but maybe they're some sort of aiming mechanism?

I've subscribed as I'm very curious to see how the $90 kit works out.

You may be better using your own controller and software. Wasn't there just a thread where someone made exactly what that kit is and used a RasPi to control it? I will see if I can find it. Would be a helluva lot easier than trying to get Chinese software, that may or may not exist, and may or not be in English.

Actually, they finally got me a copy of the software, and it's not bad.

I don't have the engraver yet, so I'm only judging the interface, but it's better than I expected. It seems to handle random image types fairly well, has really simple options for choosing how to dither them, etc. It has sliders for burn time and pixel size, and seems to have a tab for importing G Code directly.

I'm pleasantly surprised. It's better than I expected. Although the software humorously uses the phrase "Larser" instead of "Laser" throughout the interface, it's otherwise pretty good as far as translated interfaces go.

Plus, I kind of like "larser". Something whimsical about it.

You should update the OP with a download link for it, I doubt everyone else to mess around with trying to get it. Im surprised it even exists actually, glad you got it though.

Not my IP to distribute unfortunately. However, I notice that they've added URLs to some of the product pages now.

Looks like they're having a mini sale on these things (5% off with code listed at top of page):

Collection Promotion For Industrial Products - Banggood


It looks like there's only a $5 difference in price between the 120-150mW violet laser model and a 200-250mW red laser model. Not sure if that's very meaningful.

But do you want 200mW 660 over 120mW 405 ?

The cheaper ones look like something we could make with 2 leftover DVD-R/BD-R drives and some sort of frame, but at the prices BG are offering we can just buy these!

Let's see if they're any good first.

Default Re: $90 Laser Engraver Kit?

And it's pretty cool

It's monochrome, and it's not super fast, but it's very very fun to use. No assembly instructions, so it really was a "DIY" experience, but once the device was assembled, it just worked. Period. No real hiccups. The software is pretty good, and took literally 30 seconds to figure out.



This isn't going to print those gorgeous grayscale prints that I've seen from other professional grade printers, but when I look at what's in front of me, for $90, I'm VERY VERY impressed. I will have lots of fun with it!

Okay, now for some discussion of modding! Here's what I can tell you about the laser driving:

- The Arduino is driving a transistor.
- The transistor specs at a max of 500mA.
- The transistor outputs directly to the laser module wires.
- The whole unit runs off 5V, and there's no boosting, so the transistor is outputting max 5V, 500mA (and likely the voltage is a bit lower)

So now's where you're wondering how a transistor is driving a 405nm diode with just 5V?

- The diode module contains a boost driver inside the Aixiz module (a fairly typical looking boost driver).

This tells me that there's not much overhead left for driving a higher powered diode from the control circuitry's powder itself (which is just coming from USB). However, it should be VERY easy to use the existing transistor's output to turn on/off an optocoupler that itself trusts a more powerful driver that receives external power.

Does that plan make sense to others? If so, I'll design the driver.
