The MDF conundrum with my diode laser

I recently got two sheets of very pale MDF from the local hardware store, 3mm thick. Was really happy to see it cuts nice and easy and works even better for relief engravings. One might say it was a lucky grab.... Today though I decided to do some image engraving. Wanted a pic about 40 by 20cm in si...

Re: Building your own high power laser module for engraving

I still have my old 30W CO2 system but my landlord only allows me to use it in the garage, which is out of the question for me. Sure, 7W is not worth talking about if you compare it to a CO2 system. But I found that for a lot of jobs a diode is just far easier and still provides great results. Even ...

Re: Anyone like buliding cars/ hotrods/ ratrods?

Well.... I am not easy to impress when it comes to people doing backyard jobs on their cars... But what do there IS impressive indeed :) Assuming all goes to plan: Isn't it a nighmare to get the paperwork done? Engineering certificates and such are a pain in AU these days when it comes to cars and m...

Building your own high power laser module for engraving

Not so long ago people salvaged the diodes from Bluray players and such to build tiny engravers with the mechanics from old flopps drives. Since then we basically only saw how people create useless laser pointers with 7W diodes.... Lately I noticed that module housing are being sold empty on many Ch...

Re: Anyone like buliding cars/ hotrods/ ratrods?

I see that you put a lot of dedication and thought into this project.
Can't wait to see all things come together.
Reminds me of my good old days of bringing old beetles back to glory.

Staying ahead of scammers....

Did not check much around the world but right now Australia seems to be the primer harvest grounds for all sorts of scammers. And since almost all of them are "online" these days I thought it might help one or two to know a bit about the problem. Not so long ago and hackers would have spammed you wi...

Re: Cutting thicker materials with a diode laser

Depending on what software you use the mentioned features might not be available or available in a slightly different type. Check it out anyway and experiment a bit with these little known features. But what to do if Lightburn is too expensive and your software is quite basic? There is no reason you...

Cutting thicker materials with a diode laser

If you just started your new hobby you might use thinner materials or manily some nice engravings. But once you are a bit sick and tired of buying coaster and other small items you really need to be able to cut out your creations. Let's start with a short and not complete list of materials. Great fo...

Re: Rotary attachment for laser engraver

As I feared already, changing the design created far too much free play for my liking :( While the mechanism itself work just fine, three jaws with a tiny bit of tolerance, one big sprial with the same and the "lid" add up. Something thin like a pencil is no ig deal. But grabbing a glass bottle is. ...
