  • how you control the laser with the mach3, and what laser driver did u used?

  • @lavawolf666

    I use self-designed constant current driver with enabling input. The input is driven by spindle signal, which is set in Mach3 to PWM control.

  • @c4r0hv

    Hey! Loved the video! But i've got this doubt, are u using mirrors to drive the X and Y or an entire moving head?

    Another doubt is, is the laser diode a "pulsed" one? (i don't know how to power on/off) when needed...

    Regards!

    (i'm also making one CNC Laser engraver.. that's why i'm asking...) final objective will be a simple SLS machine..! :) [ i'm a noob at this... ]

  • @rmourita

    1. Entire moving head.

    2. The laser diode operates in CW mode,, but the current is turned on/off by controlling software.

  • how do you focused the dvd laser? for now i'm only able to breack them. not to use... trying to collimate the beam i always breack the laser... but i'm lucky. i've a stock of brocken dvd recorder so i can try. but some help is appreciated.

  • @djtonyxxx5

    The best way co collimate or focus the beam is to use optics from a low power laser module.

  • @c4r0hv Hello C4R0, I would suggest to put a warning on your blog: "dont connect diode to power circuit when it was ON before". Some people reported me the charged condensator may burn the laser, otherwise. Is this right?

  • Haha too damn funny, I had Family guy on in the background when i was watching this video. Believe it or not it was the episode about the evil monkey too haha.

  • very very nice.

  • I really like this job !! Would be a nice addon for my cnc router :)
