K40 Laser Upgrade Parts Kit Air assist3X Lase Guide holder2x Chinese 40Watt co2 

This kit can really get you going with your laser and make its capabilities expand. You are only using 50% of your laser without air assist & laser guide. I've used other styles of air assist and laser guide, these two are my favorite type of design to be using. RED DOT LASER NOT INCLUDED search classifieds board adjustable red dot laser diode Everything in picture included. 3x different styles of air assist, 2x red dot laser holder (with extra heads), wing nut with screw, laser head extended screw to accommodate guide holder and washer extra thickness, 1 on/off switch, 2X cr2032 batteries.

Latex tubing is highly flexiable, I would only use this around the moving head or x/y axis, keeps strain off the motors. Use cheaper Walmart stiff tubing to reach the distance to your compressor 3 styles of air assist nozzles, one is bound to work with your tubing and set up. I like this style more then the others you will find, this one doesn't require screws and slips onto the bottom of the laser head. 2 red dot/line laser guide holders, in case you accidentally break or snap one. These use the existing laser head screw/holes to attach to laser head.

Stock screw is almost to short to accommodate extra thickness, extended screw included. Red dot laser assists in checking cutting/engraving alignment to work and can save you a lot of material and misplaced cuts/engravings. Extra length screw so you can fit red dot laser holder plus washer onto the head. Wing nut for fast and easy hand adjustment. 1 on/off switch to power the laser with 2 cr2032 batteries.

You will need extra wire, I cut my wire from an old torn up aux. Cord, because its really thin and the perfect gauge. Broken headphone wire is to thin so don't even waste time stripping it. If you need an air compressor for air assist look into the harbor freight air brush compressor, its whisper quiet, cheap, and reliable. If your software has or is expiring look into the free "k40 whisperer" software, tutorials for it online and youtube.
