Wow, a mirror alignment video that actually covers the science of alignment instead of just going over the basics of centering; your my hero! Would have never guessed the position of A if you had not shown the sticky notes explaining the geometry and how it relates to your machine (seems counterintuitive that you wouldn’t aim for in between C & D). Bravo sir, keep up the good work!

I was unable to align my laser on my CO2 machine. until I came across your video on KZfaq. you are the only one who explains the ACD method and that made it a lot clearer to me. Thank you very much for the effort you took to make the video.

I'm too embarrassed to tell you for how long i''ve lost the battle of the mirrors. Your explanation has cleared the fog of (mirror) war and I'm ready to do battle again. Thanks Vince. Its great having you in the trenches. You deserve a medal!

I've watched dozens of alignment videos and this was the one that gave me my "Aha" moment. I probably have 8-10 hours of alignment attempts and had gotten nowhere. I used your A-C-D method and had all four corners lined up within 30-45 minutes. Thank you!

dude this is the ONLY VIDEO ON K40 ALIGNMENT THAT MATTERS!!!! Thank you!!!!!

Thank you sir. For those who are facing trouble in this alignment thing, this is the best video SOLUTION!

Best alignment video of the K40 mirrors of ALL TIME!!!

I cannot thank you enough for this. I struggled with my K40 yesterday for over an hour and got it within a couple millimeters but couldnt nail it down. But I saw this in my suggested videos today and thought I'd watch it. AND I AM SO GLAD I DID!!! I literally had it dialed in within 10 minutes. THANK YOUSO MUCH!!

I've watched endless hours of alignment videos and spent 5 months trying to get my OMT 80W aligned with no luck. Watched your video, had my "aha" moment and had it sorted out in 20 minutes. My laser burns perfectly now. Can't thank you enough. Excellent video!

After many alignment attempts we finally watched this...Wow, really helped, so much!!!!

Best alignment video on KZfaq. Thank you. Speeded things up a great deal and as easy as ACD!

I bought a k40 around Christmas last year.. out of the box it worked okay to get me started. After the holidays i changed airassist , ventilator , and and mirrorset/laser head. That is when the problems started. Couldn't get the alignment right. Got only crips cut at one side of the bed... Last week i spend hours of trying en errors.. until i took my time to watch this video a couple of times , take notes and a couple of tries... You are my hero!! It works like a charm now! Crisp cuts all over the bed.. and i have been able to get super settings (power/speed) instead of almost blowing the tube .. thank you , thank you , thank you!!

I've been fighting with aligning the mirrors. This video saved the day. Understanding the difference between aligning and centering is huge. Also recognizing there is only one spot that is aligned and finding that spot is critical to understand. Kudos for sharing this!

Thank you so much! My K40 came in all busted. Corners were caved in and even the rails have dents. After all those hours i wanted to buy me a new one but now it still gets aligned. Big relief.

By far the best alignment video

The best method for alignment by far!!! Thank you lots!! You made my day. I just unboxed my laser and throw a splitted beam. I started looking for solutions. I've readed that the problem was the tube. But thanks to your video I managed to make a quick and dirty alignment and even with a quick and dirty alignment works fantastic!!! I really appreciate your effort in doing this video. Greetings from Barcelona

Explained so well! I watched many videos to align mirrors and this one has got me spot on.

Thank you for making this, the ACD helped amazingly. Turned hours of fiddling into minutes of adjustment.

Genius! This is by far the best alignment method as it gives you a predictive target to aim for. I spent hours with other methods and had the laser aligned in about 30 minutes with this method. Thank you!

Thanks so much! I've watched a lot of videos on laser mirror alignment, and your ACD method is the best I've found. Unlike many descriptions yours is based on logic, the appliance of science. It cuts out most of the trial and error and speeds up the task immeasurably 👍👌
