Wow, not even one answer... Did I say something wrong...? I just would like to know if it's possible to get a very fine beam with the NUBM44 by focusing at the smallest point possible? And if so could you indicate me the which lenses I should use please..? When I look online I see different...

Hello everyone! :) I have a big project in mind and I am pretty sure you guys can help me.... Please help me... I come to you with many questions, and many of them seem to have been asked in the past but I could not find any good answer for my problem. I would like to make my own CNC...

Ok Thank you very much :)

Oh ok, but according to the image, the CO2 laser wouldn't work.. that's strange.

My question was about "NDB7A75 or NDB7875 for engraving/cutting?" sorry*

Hello I would like to know which one is better to engrave/cut? And also which lens I should use with the diode to have the best performance of burning? Because I've read that the last diode has a larger beam which is not good for burning, but it has like 2 times the power of the 3W NDB7875...

Excuse me if English if not my native language and I do not have the same reflex and ask please everytime I post someting on internet. You could be more flexible with your exigence and just help me insteed of grumbling for nothing. My questions are simple and I thought by posting in the 445nm...

Mu questions are different, here I am specifically asking which of these 2 lasers is the better to cut or engrave with their burning power. I heard different things about the last one, that it seems better but it is no more precise. Please re read my post. Thank you

But according to the lazerblade it should work, any solution to be sure it is working with this laser? EDIT: After some mails with LazerBlade who seems to use the 3W 445nm 9mmLaser Diode +G2 Glass : " The laser cannot engrave clear acrylic without a coating. This is because the laser frequency...

I'm not planning to use any form of coat. But with all the examples in my first post, it should be enough to be sure I can with this laser right? Today I engraved acrylic with a Co2 laser at 15w, and even cut it, I did it in a lab, it's not mine, I just wanted to try. I really would like to do...

I'm planing to make my own machine, why? I knew about the glasses, I need to find them too. I won't let my eyes be hurt. Really about the acrylic I don't need to cut it, I just want to engrave it

Hello everyone! After spending most of my day on the forum I decided to create an account and post my message :) First excuse my English, this is not my native language :thanks: My case is simple, I'm totally new with lasers and I want to engrave acrylic. I already made some research, and what...
