ATOMSTACKAir Assist Kit, Laser Engraving Machine Accessories, Air Assist Laser Cutter for A5 Series/S10/A10 Pro/X7 Pro Laser Engraving with 2m Tube for Smoother Cut and Engraving Edges, 10-30 L/min

This is Avery good machine, and has stopped burn marks on the wood

Easy to assemble, good quality, and great fun to use.

I was undecided between this and the XTool D1 (this was before the newer D1 Pro came out). I knew I wanted a true 20W laser diode for better cutting power and at the time the only way to get that with the XTool was to buy a complete 10W machine and then upgrade the laser module, which made it an expensive option. It also didn't come with air assist. So that made it an easy choice and I ordered the Atomstack A20 Pro.Despite the fact that the XTool D1 Pro 20W has now been released, which comes with a 20W laser as standard, it still works out more expensive for the same power and I'm still happy with my choice. I don't have direct experience with the XTool but it looks to me like they're putting a lot of effort into marketing (via Youtube, mostly) to gain some traction in the market. Atomstack have obviously been making laser cutters for ages so I felt sure they know what they're doing, and that certainly seems to be the case now that I have one.The Atomstack A20 Pro a very high quality bit of equipment. Everything is very well made and extremely well packaged. I think there's almost no chance of damage in transit as it all comes packed in layers of thick foam. You have to assemble it yourself but it's not difficult and only took about half an hour. All the necessary tools are included, although I found it easier to use my own tools. The only minor issue I had is that the height adjustment of the laser module was a bit tight, rubbing against the metal bracket it slides into. I solved that by carefully wiping some PTFE dry lubricant on the bracket and the mating metal part of the laser module and now it's much better.I connected it up to my laptop, on which I installed the trial version of Lightburn (which is fantastic and I'll be buying a licence when the trial expires). It immediately found the laser cutter and after entering a few very basic details it was all set up and working. The limit switches mean it can accurately home the laser to the bottom left corner, which is perfect for accurate positioning on your workpiece. Within a couple of hours of opening the box I was up and running, makes some test engraves and cuts. There are a few small sample pieces of wood and acrylic included, but I quickly moved onto bigger bits. Tip: cardboard is great for testing and costs almost nothing.It cuts and engraves beautifully once you get your settings dialled in. The air assist make a huge difference to the quality of the final result. The scorch marks just disappear. I'm mostly using 3mm MDF at the moment, which it has no problem at all cutting right through in one pass and I've no doubt it could manage thicker MDF / plywood easily. I'll be trying some dark acrylic next. I'm really looking forward to doing some real projects with it.One thing you must know is that it generates a LOT of smoke when it's running, especially while cutting. Obviously the same will be true of any similar machine. You either need to put it somewhere with very good ventilation or get / make some sort of enclosure with an extractor fan. I ended up buying the Atomstack B1 enclosure, into which the laser fits perfectly. It's not cheap but it's really good quality and adds a lot to the machine overall in terms of practicality (fume extraction and noise reduction) and safety (it fully encloses the laser while running with filtered acrylic windows so you can safely watch what's happening). It even has a cutout in the bottom for the rotary module to sit in, so you don't lose that option by using the enclosure. I cut a vent hole through the wall of my workshop for the fumes to go out through. A bit of an effort but worth it!I'm also intending to try installing a camera inside the enclosure. Lightburn has a great feature that uses the camera to help visually align your job with the workpiece.As a cheaper option you might like to have a look at the Comgrow or Sculpfun laser enclosures.Overall I couldn't be happier with it and I'm really looking forward to using it some more.

After I tested really I have to change my reviews about it I have to be honest Frankly, it is expensive because it does not do a perfect job. It is not accurate in work. It makes mistakes during movement. Then I had a problem with the air line. It is blocked. Air does not pass through the laser. It is not good for writing on stainless steel. I wish I had read and researched about laser first before seeing this

Great bit of kit works great with my Atomstack a5 m50 pro laser and engraver highly recommended with to anyone and the extra stuff you get for all different Atomstack laser module's.
