    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

    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.

    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
    Les

    Do you have any actual diode in mind? Could you please share a weblink?

    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.
