hello guys,
i’m not sure if to buy an ortur master 2 pro or a neje master 2s max.
the ortur with new firmware can engrave photos at 9000mm/min and this is the speed that i need!
but on the other side the engraving surface is only 40x40cm vs the 80x40 of the neje model.
Now the question is:
at what maximum speed did you manage to run the neje 2s max??? i can’t find anywhere the maximum supported speed, did you tryed it at 9000mm/min as the ortur or is not possible???
neje use their burning time MS unit that are milliseconds per pixel but i have no idea how could i translate in mm/min…
anyway i would use with neje the single beam 30w (7.5w output) N40630
Please let me know your experience 
The Ortur with new firmware AND a new X motor/carriage are necessary to get the higher speeds. It’s not just a firmware change, the new carriage allows it to go at a higher speed.
yes, i agree with you! do you know which speed is possible to achieve with the neje master 2s max?
Obiously biased but… each machine has its points of Pros and cons
What you failed to state though and is a bit paramount, is what are YOUR use case requirements
Do you need the higher 800xx footprint? Or is speed that you seek
Do you need acuracy or not… etc etc etc
Without your requirements i think both machines are a good buy, or a bad buy, for different reasons.

actually i need speed for photo engrave, no cutting, that is why i would like to know the real maximum speed of the neje model. i already know that ortur can get great results on photo engraving at 9000mm/min but the working area is too little for me, that is why i’m considering the neje model
Ortur frame is superior, Neje frame by its lenght and choice of rails is not
You can overcome this by bolting the Neje frame down and square it propperlly
This has the con of making use of a full table permanently
Even with engraving images, and i am assuming the simplest more reactive material as black painted canvas, i doublt you will ever get near them 9000mm/min with a neje 30w, Which is basicly the same optical output of the LU1-4/lu2-4 orturs.
so… is a tough call, you will have to give up frame size for speed. But… thats really physics at play.
This said… Buy Ortur! 
P.s. Edit. By Ortur frame being superior i mean simply being smaller, full metal frame with a more rigid construction it simply results in a MORE rigid frame. Thats all.

thanks for the answer!
in conclusion with the ortur 40x40cm working area and LU2-4 is possible to fast travel at 9000mm/min. i imagine that considering the frame and carriages of the neje the fast movements are probably half or third of that speed?
Well you can check the Neje Grbl Firmware max travle speed settings and compare.
You can tweak it above the factory defaults but then you are on your own
YOu can also make the ortur go at 20000mm/min, but if you do you will be going outside the validated specifications.
And you will be fighting physics with physics
The faster you go, the more artefacts you will get on your engravings.
Which will leads you to reduce the acceleration values, which then will puzzle you when you realize you are running at 10000mm/min but it takes as long to finish an engraving as a 5000mm/min with default accelerations.
Is a Tug of war between the 3 Monsters: Speed, weight, and acuracy.
Only 2 of those 3 can - normally - win.
