Ill order it so i can get my airassis on so i can start cutting my wood i had 3 mm ply wood and do not cut through and i got mdf wood and nothing whats to cut through went through al the video’s on youtube and still no luck.

Hopefully it wil cut through after i add the compressor and piping.

Thanks for the help

how many passes you do to cut 3mm plywood? and what speed and what power?

Some of ttm was 6 and the 8 an then 10

This one was 12passes

well, first thing i notice is that you have 2 problems:

  1. seems to me that you are not focused
  2. if those are circles you also have a belt problem.
    Belts should be tight but not stretched like rubber bands

I have a small compressor in the garage for nail gun & general “move the dust” use. I connected an inexpensive air control ($5 +/-) to my laser. The shop compressor connects to the air control. I’m able to control the air via a nob on the air control. Works great.

I use a small diaphragm compressor that I bought secondhand off eBay. It’s the sort used for an airbrush. Seems to be perfectly adequate when cutting both plywood and ‘real’ wood.

the important is that it’s oil free

If you’re cutting lots of wood and thick wood that creates a lot of smoke, a “normal” air compressor may be what you require. I cut 1/8" wood and use a fish tank air supply which works really well. You don’t need much, it’s just to clear the area in front of the laser lens. I had a very small but high pressure air compressor (used for air brush) but it was TOO noisy, and overkill. Fish tank supply is quite inexpensive, $25 CAD.

I tried a bunch of different air sources on my laser and summarized them at the link below. Basically I found that if you have enough air, you have enough air and adding even more is not going to help you. For my setup it seems around 3 psi is plenty of air, that is with an over the lens air assist with a 2 mm nozzle.
If your nozzle is more leaky you may need more air.

The easiest two different ways I have found to provide a nozzle have been to use a football inflator nozzle mounted in a 3D printed holder or a veterinary needle used on cattle or horses mounted in the same holder hooked up to an aquarium air pump that provides at least 50 liters of air an hour. A metal nozzle has the added bonus in that is capable of directing more air into a precise location then a 3D printed nozzle. Which if printed with anything less then ABS or one of the Nylon amalgamated filaments you will find to be rather porous. I’ve tried a few of the 3D printed nozzles using PLA and PETG and have had them blown apart with the pressure of an aquarium pump.

I went to the local petshop and bought the largest fish tank air pump they had - it works like a bomb on my Aufero Laser1 with ShortFocus Module!
