Air assist manual and question about pressure

Post by Nig »

Hello,

I have bought the Neje Master 2S max with F30310 laser module and air assist kit:
(NEJE MF15 MANUAL CONTROL AIR ASSIST KIT FOR NEJE F30130 LASER MODULE-1.5MPA)

I can't find any information or manual about the air assist kit. Would you please provide a manual?

Why is there a nozzle in the package?
What is the best way to mount everything together?

In one F30310 drawing I can read "0,6 - 1,5 MPa". This is quite a lot of pressure. ;) Should I really use a minimum of 0,6MPa for air assist or does this means the maximum has to be between 0,6-1,5MPa?

Thanks for your help.

Nozzle is a gift, if it is F30130 module, the nozzle is not necessary, NEJE will update the video in NEJE.WIKI, please pay attention to the update;

Hi,

I used this pump with the air assist kit and it works brilliantly (I could barely get it to cut anything using the plastic air assist end the laser comes with) it's rated far lower than 0.6Mpa at >0.015Mpa but now I can cut 3mm MDF in a single pass with nice clean cuts !!

As for the nozzle (and spare nut & bolt) I've no idea, but using some of the hose in the kit I made a small attachment for my Master 2S 20W which has made a massive improvement to it's cutting & engraving !! I just used a thin bit of plastic screwed into the threads on the bottom of the laser with a small cube of wood with a 20 degrees angle hole for the nozzle with a bit of glue to hold it.)

Hope that helps

This makes no sense - or maybe their specs make no sense. 0.015 is over 40 times less than the pressure they recommend. Even the $100+ pumps on Amazon do not have 8% of the pressure that Neje recommends. How can this be?

NEJE recommends the use of oil-free air compressors to provide the air source. NEJE has developed a new type of automatic control valve, which can be controlled by either M8 or M7 commands. This function will be supported on NEJE 3 series equipment, the new NEJE 3 series The motherboard supports the replacement of the motherboard of the old equipment, please pay attention to NEJE update; Regarding the use of the oxygen pump as a control aid, it is recommended to use a device of 100W-300w, so that there is enough air pressure to achieve the desired effect, but the oxygen pump has 2 disadvantages: 1 . Noise is huge; 2. Manual control is required; NEJE next designed a relay module that can be controlled by M7 or M8 commands, which supports a wide voltage of 0-250V, and can control exhaust equipment and oxygen dispensers; if the power supply exceeds 36V , It is recommended to use under the guidance of personnel who understand electricity, high-voltage operation may be risky; NEJE recommends using solenoid valves to control air compressor pipes; use relay modules to control smoke exhaust equipment less than 36V; :)
