General Discussion / Re: Has anyone used this 2.5W Blue Laser? Advice

Be advised to check out the post on GREEN glasses.....there is important safety advice on it.  Suspect the rating of these green glasses....in fact suspect anything quoted as safe from China!

Might I suggest  people who ask for info regarding certain items mentioned in a post  let the rest of us know which country they live in.

This will enable  other posters to  supply info appropriate to the original enquirers country as opposed to  pointing them to a place that could incur a stiff postal charge.

Cheers, but a UK specialty store is as bad a US specialty store since I am in australia.
I will add "engraving laminate" to the search list though .. still nothing on aliexpress or banggood, surely they sell it somewhere..



I DID  point you in the direction of an Australian supplier.  in my post  above .......http://engravingsupplies.com.au/

Equally entering the following in Google should bring up information.....Traffolyte Engraving Material

Plastic Stockist offers a fantastic selection of engraving laminate in an extensive colour range. Consisting of 3 or 5 layers of opaque coloured plastic sheet permanently bonded together to give an engraved finish each time. When engraved, our Traffolyte material gives the effect of a two tone material allowing the underneath colour detail to show through. Our engraving laminate gives a durable, high quality finish and due to it being naturally hard wearing no further surface protection is required. Engraving laminate is also resistant to water and oxidization and is very difficult to ignite.

(I have no interest in this firm).

You can buy the right size ceramic screwdrivers.

https://www.google.co.uk/search?q=set+of+ceramic+screwdrivers&oq=set+of+ceramic+screwdrivers&gs_l=psy-ab.12...2809.5327.0.7413.7.7.0.0.0.0.295.911.4j2j1.7.0....0...1.1.64.psy-ab..0.2.410...0i13i30k1j0i8i13i30k1.GD9ieUlnylU

Also metal will do but be careful..they use Philips type.....Buy a cheap set of the latter one of them will fit.

About a week or two ago, I checked out a thread about using a computer fan or blower to clear out the debris of the laser etch. There they showed a mini blower as a suggestion for the task. Well I got sidetracked and forgot the thread location. Anyone recall?

Enter BLOWER  in  SEARCH.  :-*

Think I'd rather pay $350 for a 40 watt CO2 and fix it than mess around with an overdriven diode.

Me too..but it does not stop at $350  by the time you have adapted it..! and it only has a 12 x 8 work area.......

My experimentation found the secret to consistent efficient cutting is a high velocity low volume needle air jet directed accurately into the laser cut.

Def agree..
It  seems it is important to keep the lens clear of dust build up as well .

Yep..you def need a blower to clear the rubbish out of the way...makes a big difference.
Nice mod.
 There are some very small blowers around (see phot with dimensions in mm)  work on 5v that give a reasonable "blow" that could be mounted out of the way and stlil use silicone tube and brass tube.   The one shown I think..gives out about 2 cfm

Trouble Shooting / Re: Assembling the lenses correctly
« on: August 05, 2017, 06:05:19 AM »
Thanks for your response.
As i tryed to figure out the right positions of the lenses i slipped with a tool. There was a contact to the laser diode i think, because now it is broken... ;-(

;-liver

Cant you resolder the contact or make a new one and solder it on?

Do i have to add some extra fans for the laser module to prevent overheating of it?

;-liver
Should not think so if you are not using full power.  IF you intend using it at MAX then I would say Yes...up to you...
On the other hand..if you want to cut really thick wood then buy a scroll saw....(jigsaw)..... :P  I have a 3 watter but if I cut thicker than 3mm I use the saw.....Quicker as well  if its not too complicated (which it normally is not)...
