Excellent laser that can work with 3018 (non-PRO), too

I wanted this laser due to its fixed-focus lens and finer, rounder spot. After writing Sain Smart twice and receiving no reply, I decided to gamble and ordered it anyway. The accompanying instructions (quite good, by the way) included a fairly detailed description of the various inputs, including the two-pin PWM connector. I was concerned that the 3018's power brick might not have enough capacity (tho it does power the original 5.5W laser), but since it has its own power brick, I was only concerned about the compatibility of the PWM interface. I put my oscilloscope on the PWN pin from the controller and discovered that it emits a 12VDC pulse string which is exactly what the new laser wants...good to go! I clipped off the three-pin connector that the original laser uses as well as one end of the two-pin connector cable included with the new laser. It was a matter of five minutes to connect the black and white wires from each cable together, solder them and shrink a bit of heat-shrink tubing over each. The red wire on the original cable (+12VDC) was taped off to protect it from shorting to ground. Praying to the gods that the magic smoke wouldn't escape from either the laser or the controller, I powered both up and told Lightburn to trigger a 25% burst...success! After a couple of days of engraving, I can say that the laser does, indeed work with the 3018, and it works extremely well. Very crisp lines and very powerful. Focus is dead easy using the nice steel cylinder which quickly allows positioning the Z axis to the required 20mm above the work surface. I highly recommend the laser kit.

5.5.Watt Blue Solid State Laser...

Very easy to install. The laser makes very detailed engravings, if set up correctly

Very nice

Fitted onto my PROVer with no problem. Fixed focus is much easier to use than the older variable focus ones.

Great laser

I have so far found this laser to be excellent. I was really keen to use it for cutting veneers which I am pleased to say it does brilliantly. I thoroughly recommend this product. I would also encourage people to use Lightburn software. It is very easy to use but also very powerfull. Works well with Gemnitus ProVer and does not need any export/import to a LaserGRBL package. Much less hassle than say Vcarve laser module which although has Vtransfer does not give you much control over GBRL settings.

5.5 Watt 3018 Laser

Fulfillment of my order was very quick. The instructions were specific to software I don't use, but installation was pretty straightforward. This laser IS hot, so use the included glasses and appropriate caution. I would buy this again.

Great value

Best value in a low power laser that I've found. I mounted it to an aftermarket CNC machine and it works flawlessly. Fast and easy hookup and operation.

Great Little Laser

I mounted this laser on my X-Carve CNC machine using a homemade bracket. It works flawlessly and I am extremely please with it. It functions as good as units costing 4-5 times as much and was simple to connect and start using. Thanks for making laser engraving quick and affordable.

Excellent but...

5.5 watts is a lot of power if you are attempting to engrave wood. Even at PWM of 45% and well focused it does a lot of burning (e.g. you get a fairly large spot). If you plan on doing some fine work on wood you might be happier with one of the 2.5w lasers. The PWM percentage versus the power output is NOT linear. So what we end up with doesn't come close to the resolution in wood one can get from the 2.5w. All considered though, the price performance of this laser is excellent. I recommend you consider purchasing both a 2.5 and this 5.5. Use the 5.5 when you don't need the resolution but want the feed rate that the higher power affords you. Use the 2.5 when you need very small print.

Great laser, hard to find documentation.

I've been working with the laser now for 2 days and finally am making progress - but if it were not for the Sainsmart users on Facebook I would have given up by now. was not too hard to find but the 'missing manual' that a Facebook user had to point me at should have been included with the purchase: So 5 stars for the hardware and 1 star for the documentation averages out to 3. It's worth persevering (especially now I've pointed you at the documentation :-) )
