Diode Laser Cutting Focusing

Hello all

I just put together my 2w laser diode (L-Cheapo) and got it working now on my 3D printer. I'm to the point now where I want to use it for the first time. I have loads of questions but I'm slowly figuring things out. One of the things I'm wondering about is the focusing. What is the best procedure to focus the lens? My laser dot seems a little fat and oblong right at the moment. It does burn but perhaps I need to adjust it.

Sorry everyone. I just saw a thread here: [forums.reprap.org]

Hi, just wondering what laser did you get?
Did you get a kit/all in one?
cost? (ebay?)

Thanks
Chris

I bought the L-Cheapo laser kit. It works very well. However, I bought it before I discovered the jtechphotonics kits. The latter are a bit more professionally built. The L-Cheaper is a bit cheaper.

Yes, I looked at JTech, I sent them an email, but go no response... makes me wonder...?

I'm thinking I can piece one together on ebay for half the price.

@Mogal
Jay responds to my emails regularly. I've ordered several accessories from him too. No problems and nothing to worry about in my opinion. Of course if he doesn't respond to you then I can see why you feel that way. If you think you can source it for half the cost then post your links. I'm interested.
