Aliexpress 300mW diode
Hi Folks,
I wonder if anyone of you has any experience with Aliexpress' 300mW diode engraving?
Is it powerful enough to engrave painted plexiglass?
Is it fine enough to engrave 2-4 mm letters?
Thanks for any comments

Re: Aliexpress 300mW diode
Hi mefiu,
please be more specific and give us a link to the machine you have in mind.
I've been looking at them, just like you did, and their mechanics appeared to me to be router-alike.
I bet - their precision would be of a mechanical router , but i can't be sure.
Regards.

Re: Aliexpress 300mW diode
Well, first in the row:
http://www.aliexpress.com/item/New-A...304557186.html
I've my own cnc machine, but due to some misalignment in Z axis, it cannot be used to engrave.
My main question remain the same: is this diode powerful enough?
I've some previous experiences & tests with DVD diodes, but they were week and cannot burn painted plexiglass...

Re: Aliexpress 300mW diode
Mefiu,
I have one of these cheap laser engravers using a 300mw laser. They are pretty useless on anything but would or paper.
What I am contemplating is to up the diode to 1.6w and then I think it may be ok for engraving.
Regards

Hi,
I was going to fit a module complete with Heat sink from Banggood.com. Have not finally decided yet.
Here is the link, hope it helps, not cheap .

Re: Aliexpress 300mW diode
Not cheap indeed.
Give us a hint if it's worth this money and capable of engraving painted plexiglass when you buy one.

Re: Aliexpress 300mW diode
Just to pick up the subject.
Anyone has any experience with Chinese blue lasers, powered 2000mW or more, to engrave plexiglas.
I'm still hoping to give it a try, but without any recommendations it's a risky business for me.
