Hey Marcus,

Yep there the ones I'm talking about.
The one I got had a removable core so I don't have the aluminium angle surround getting in the way.

600mm x 500mm cost me AUD 60, not sure what the prices are like in the rest of the world.


12"  x 12" in the UK  about 16 on e bay.  (A$32?)  Larger types of course more expensive.

I remember reading in a model mag,   a chap advising people buying RC  transmitters to give them a good shake.  remove the back..turn upside down and shake again..... AND  watch the bits of wire and solder fall out from the board inside!!.....
Mind you..it depends in your case where the board was stowed...it might have picked up moisture...and POUF!!

Cutting / Re: Air Assists Compared?
« on: March 21, 2018, 01:30:11 AM »
An airbrush compressor  would do the job,  but you would have to check each to find the quietest as some make a noise that some  people might find annoying! - but..as long as the air intake is open  for cooling...it could be placed in a a sound  insulated box with a lid for access.   (There are some..said to be silent..Google...) 

Airbrushes run at around 45 psi I believe but when used with model paint the PSI can be adjusted by the "brush".
 I would suggest a cheap small fish tank plastic air valve would do the same  in place of the "brush" adjustment  or a smaller diameter pipe  with valve  from the main one....??

Thanks @ROSS. I appreciate that it's tricky but I'll be sad if I blow $200+ on a laser diode when that's a significant chunk of a K40 anyway.- Ian

Think its a chance you take with laserheads..some last a fair time and some go bang after a few hours.   The K40 needs some work to get a decent job from it which can cost another couple of hundred dollars. AND  you need to know what you are doing! 
The last line on the post above nails it.... :P

Ask ZAX..he knows all about the "blue box" lasers....

Opinions will vary.
 Much like asking someone what their car is like in performance and comfort. (It will always be THE best!!)... ;D
The only way to find out is to buy one!
Expensive I know  but quite a few bought a 5 watter as their first laser  and appear quite happy with it.  Others bought lower wattage lasers and are quite happy with them....   
I think the thing is , that you just want to use the laser on jobs it will do   (plenty of info on here as to which laser will do what jobs)....and not on jobs it will find impossible  (like expecting a 2,5w to cut 1/4 inch ply  in one go!! )

Go on..treat yourself   :P

Why do I need housing? Because of the fumes? Or protection from the lasers light?


You really need to run thro a few of the Laser websites on Google (the Laser  Safety types).  They will tell you all about laser  operating  safety.  Equally there are sites telling you about what can be cut and what is not safe to cut -  PVC for a start should be a No No....altho some have done it..PVC fumes can kill.

The 2.5 watt lasers have a built in board. The 3.5 and up lasers have a separate board. I have an A3 and the wires that come with the laser and board are short. Where is the separate board usually placed?

Most pictures showing the laser have it on the rear -  as I have.  Not sure why you have short wires.  Mine from Bangood came with long set of wires that proved a bit of a nuisance if not "tamed" in one way or another.... ;D

Well...for a starter..there is plenty of info on here.  Zax and Ralph (Administrator) have vids and PDFs available if you look around their signatures...and plenty of free advice from the regulars....

1st Piece of advice.   Buy a fire extinguisher!   ;D

Be interesting reading some of the insurance claims if the house burned down!  (and no doubt they will have heard it all before!!)

(I am reminded of a high speed teleprinter used in one of our offices that had the paper jammed.............the print head kept moving from side to side at speed.....friction caused the paper to burst into flame and the office was wiped out.......(the staff had left for the night  and left the machine to itself).............  ;D ;D

I thought it was too good to be true.  One has to be very wary of these claims from Chinese sellers.  15w ?  Mmmmmm...

Of course anakein  could always buy one and test it for us over a 6 month period!! :P :P
