Mirror Alignment for Co2 Laser Cutter and Engraving Machine Quicker and Safer Alignment Tool (16mm/K40+)

Bought one of these when they first came out for my 60w laser. It got the 60w laser running like a champ. Here we are 3 years later and I had to order a large size for my 150w laser.These are the best quality out there but because of manufacturing processes I can see they are not dead on 100% of the time but this is not an issue as long as you know how to use it properly. The best way to check that the laser alignment tool is machined well is to roll it on a flat table, I use the top of my co2 laser door. Looking at the beam where it hits the wall, roll the laser on the flat surface and you might see a slight wobble.If you see no wobble then you can reverse align mirror 3 (the final head with the air tube and lens) and mirror 2. If there is a slight wobble you can still align mirror 3 far better than you would without the tool but mirror 2 might be iffy. Even if you have a perfect alignment tool, double check your mirror alignments with the tape burn method.The ability to target the actual laser tube beam at the correct spot on mirror 3 is just icing on the cake. There are a few videos showing why this matters and how much more power you can get out of your final focused beam when everything is done correctly. Would buy again and recommend to anyone I know with a co2 laser.

Got it today in order to align my cloudray k series mirror setup on my homemade Co2 laser. Took me about 20 mins and had everything aligned. Definitely saved me tons of time and headache. You still need to align the first mirror right out of the laser tube the traditional way but this allows you to align both mirrors on the gantry with ease. Worth every penny.

I spent 3 days following the so called easy to line up a K40 laser in under 60 minites videos and got nearly there not not quite, saw the videos online for this tool and decided to give it a try, the baterys get used up real quick, 25 min and they was dead but luckily you get a good supply of them with the tool, 10 I think it was, takes 3 at a time but straight away this tool shown me that the laser head was the main problem, took me under 30 minites with this tool and now I have a good even cutting surface all over the bed, this tool is awsome, well made machined and precisse, the laser shines through a hole a fraction of a millimeter, you just unscrew the lens and replace with this tool and line the mirrors in reverse, this thing made aligning the lasers not a breeze but still a heck load faster and way more acurate, plus it saves the use of yards of painters tape, just make sure you have a good supply of batteries, the seller recomends AG3, LR41, SR736, V36A, SR41SW and all of these I have found on Amazon so if you order this tool then get a supply of batteries too.
