There's a Scale on the right side of the "Z Axis/Height Adjuster". How I zeroed my height: - put the zero of the scale on the bottom position (20... this scale should be inverted) - slide the laser head up and down until I get the finest laser point on top of the laser bed (the honeycomb panels in your case) - lock the laser head From here you can easily adjust the height by rotating the knob. I believe the scale is in mm. According to the settings on the Neje software, this machine can go: 12000 mm/min (X) and 7500 mm/min (Y). You should bolt the machine down if you're going speeds above 3000 mm/min specially if you're engraving small parts/areas, because the start and stop of the head will shake your table (and may slide the machine out of place). One final advice, according to Neje's wiki, you should use 100% power for engraving and only 80% for cutting. It's always recommend to only go up to 80% to extend the life of the laser.
I've been wondering about the need to focus the laser on these machines. I always thought a laser was by definition a straight beam. What's stopping manufacturers from making perfectly straight fixed focus lasers?
I would think that it might have something to do with these being LED based lasers. However, I've seen CO2 lasers where you have to set the focal distance as well. It might have something to do with the optical power rating too. We need someone smarter than me to chime in. Thanks for the great question!
Hey Brian! It's slower in the maximum working speed which is listed as 1000mm/m. Most machines of similar construction have a working speed of 5,000-10,000mm/m. With the 3 Max being as large as it is and the fact that both the X and Y axis have the added burden of hauling the cable chains around, I believe lowering the speed was the only solution to balance cost and performance quality. The resolution is inline with most of the machines I've reviewed to date. Thanks for asking a great question. Hope things are going well for you!
so I have been binge watching your videos, im a complete beginner at laser and im trying to decide on what to buy. At this stage I would only be using it to cut chipboard, do you have a suggestion...?...im leaning towards the Aufero 1 because I have limited space as well...but I definitely have learned a lot looking at your videos very informative. Thanks for the time and effort you put in them
Mr David, do you feel that the price is fair, especially for someone who has only used a NEJE Maker Mini? So I'm not totally unexprecireced but I don't have much experience with Lazer engraving.
That's a tough question. If you compare the 3 Max with an Atomstack x7 with the extension kit the Atom stack is currently less expensive. The 3 Max comes with the auto air assist which is very useful. It's not an exact apples to apples comparison. They are both good options for the extended size.
Thnx; Interesting review It seems a GOOD machine indeed. Given the price-point of this thing, it performs really well And yes, when you double or quadruple the footprint of an average machine, the total time to complete a very detailed job will grow a LOT! This imo seems along the lines of a very large 3D print, so not unusual at all. Perhaps a tweak of 'feeds 'n speeds' / G-code can help you out somewhat. Hearing your cons, they appear to me to be more along the lines of 'unrealistic expectations'. Perhaps your review helps the viewers to to develop a feel for what to expect.

Nice Airplane reference
Super review. Accurate and to the point. No hassle. Tnx!
Thanks so much for watching!

Fantastic. Great Presentation.
Can this laser be upgraded to a more powerful one so bigger jobs can go faster? Not sure if that's how it works or not.
So is it slower than most lasers this power or is it slow because of the resolution?

Hi nice video thanks. But can you maybe tell How you did Focus Laser? I can't my to work like that:(

Very valid points on setting the expectations. I appreciate you watching and commenting!
