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, so...?

I would like to try to engrave/cut acrylic so I guess I need a lot of power for that. And I don't want to try CO2 now, but maybe you have a better idea?

Thanks for your help

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

Thank you

Next time, please ask your questions in the
same thread since we are still talking
about the same project. See there? I
asked nicely and said "please."

Post your questions in the original thread
and I will answer them.

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 laser forum I could have more answers, that's it.
How old are you to rate 1 star my post just because I already asked the same questions somewhere else?
Relax, it is just a forum man.
