Self made CNC machine with DVD writer laser burns laser hazard logo on CD case

[shark2v]

where can I get a laser like yours? good work

[ExpertCMX]

Fucking Amreican Branis, Rule the world!!!!!!!

[abpccpba]

Nice work. I like your use of draw rails.

[kingmike40]

would the laser be powerful enough to cut through wood about 1/8" thick.

[Bigmig639]

Would this work on an xbox 360 case and do you have cnc plans if you do it would be great if you sent me the plans

[c4r0hv]

@Bigmig639

Probably would work, but it depends on the casing material and color. I don't have any plans.

[omgitschrislol]

Will this work on aluminium? LIke if i were to do this would it put a deep enough grove in it so i can fill the grove with paint so it stands out?

[MrPlaystation345]

great work man I'm impressed, and that takes alot.

[19Knorke93]

how did you manage it the laser on and off about?

[19Knorke93]

what program do you use?

[c4r0hv]

@19Knorke93

Mach3

[reesk92]

laser smoke dont breath this

[W3TIC3]

thats

awsome.

[typodaemon]

There's a joke to be made here about being a CD burner... but I'm gonna need more caffeine before I figure it out.

[Shandybrother]

cant get to your web page, does not seem to exist

[martyfriedman666]

That thing is awesome! what power is the laser? what sort of mW range is it in?

[msichal]

Źle się to ogląda po przypadkowym spaleniu podobnego lasera...

[advthinker]

Where did you get your plans for the homebuilt cnc, or is that of your own desinge, either way nice set up you have there.

[c4r0hv]

@advthinker

This one is my own design. Thanks :)

[ThePyrochief6]

Cool

[teja89max]

Can you burn holes in PCBs with this setup? Or perhaps with a more powerful diode?

[SettimaLegione]

@teja89max No, impossible. Homemade laser from DVD (red laser) can burn only dark plastic. Homemade laser from BlueRay (blu laser) can burn any color of plastic, foam and paper. In both cases the productivity is low: only few mm/sec. To vaporize copper on a PCB it would take an enormous energy. It's absoluty out of range for a hobbist.

[lupusk9]

@SettimaLegione what about engraving on rings or like metal?

[Gardinenstange3101]

Here u can see why the people have books @ home

[cyberdems]

awesome job

[KeithWasHere1]

what are you using to power the laser? what kind of laser is it

[c4r0hv]

@KeithWasHere1

1. Switch mode current regulator.

2. Diode laser, 20x DVD-RW diode in it.

[KeithWasHere1]

@KeithWasHere1 got a part number/model number on that current regulator?

[didaloca]

I like how you have recycled an old computer desk for this :)

[c4r0hv]

@didaloca

I haven't recycled any computer desk for this...

[sparkyuiop]

@didaloca Really? The computer desk... That is an amazing homemade effort of a precision piece of equipment that took some huge and rare talent to build but you like the recycled computer desk best did you. Ok, that's good and green of you.

[MultiPassmore]

@sparkyuiop

Indeed!

[uberloss]

mam taki sam

słownik!

[BoSoffen]

awesome!!

[SettimaLegione]

Video is real time or accellerated?

[c4r0hv]

@SettimaLegione

This one is real, not accelerated.

[SettimaLegione]

@c4r0hv so, the speed is much faster than any physical tool!

How much mA are you giving to laser?

[FREAKGLUE]

Awesome wow!!

[Elamin008]

what is the name of software that you are using , thank you sir

[c4r0hv]

@Elamin008

Mach3

[hackie77]

i had this idea some years ago, but i think your realisation in low budget is awsome

:D

as y,x drive i had a Plotter (for Pens) in mind, these old fashioned things u know

great work

[FalloutBe]

very nice! it's really awesome :D

[djcossie1]

Thats who you are your Q out of 007 as there is no more films you need something to do lol. Buddy keep it up you are brainy.

[GARICOL9999]

no joke intended but at first is that a homemade cnc controlling software ,too, thnks?

[pawcios123]

Skąd masz te silniczki z paskami zębatymi?

Maszynka zajebista, bardzo mi sie podoba oby tak dalej!!!

[ayoria92]

woww en verdad icreible y muy ingenioso tu invento.

[kurtee3]

I'm using Mach3 on my own DIY CNC and would love to swap out my cutter and use a laser.

I'm Curious how you setup Mach3 to enable and disable the laser while running your G-Code!

Thanks for your response.....

Kurt...

[foam27]

@kurtee3 The G-Code M03 and M05 will turn an output on and off, from there hook a solid state relay with an input voltage of 3-30V to the printer port assigned pins to activate a 120V relay that can turn the laser on and off, or activate a shutter actuated by a solenoid.

[dmatrix5]

You're a genious man. Good job.

[brenck]

So will thoose laser pens that are 400mw will actually do better then yours? Thank you for reply

[c4r0hv]

@brenck

If they really are 400mW and you focus it properly, then probably yes. But like I said, it depends on the burned material too.

[brenck]

Really nice, how much power is the laser? Can you cut paper? I wonder if bluray writer laser would burn even more...

[c4r0hv]

@brenck

This particular laser is something around 240mW (measured). It can't cut white paper, but if it's black or grey, then it can. BluRay diodes can be much stronger (diode from 12x writer can give even 500mW), but the burning abilities depends also on the burned material.

[yoshimura2500]

holy SHIT! amazing!

[J1I9M7M4Y]

Wow!! Really impressive. Can i buy your brain plase? :) 5/5

[c4r0hv]

I got only one so I don't want to get rid of it. How about kidney? :P

[Blizzardo1]

@J1I9M7M4Y I want his brain too. Amazing dude. 5/5

[benjamin241000]

des is ja der hamma

der laser is von nem alten drucker oda

[ONPRIEL]

great , 5*****

[Dinasuke]

hardware from old printer right ?

[c4r0hv]

No. Motors + timing belts from scanners, and ball bearing drawer slides :)

[HVdischarge]

Thats awesome, are you controlling this with a parallel port? if so how do you program and control this to go where you want?

do you need a stepper motor driver too?

Thanks

[c4r0hv]

Yes, I'm controlling it with parallel port. You should read something about CNC. There are a lot of programs for controlling CNC machines. I'm using Mach3. There's also some kind of standard, called G-code, for describing the machine moves. Yes, stepper motor drivers (at least two for X and Y) are needed.

[HVdischarge]

cool, i have been looking around for a while for a free program that you can manually program. or if its possible to have some sort of drawing software (like paint) that you could draw the image you wish to etch/cut (to scale) and it would automatically follow the pattern drawn. do you know if there is such a thing?

is the stepper motor driver is just an IC?

Thanks

[c4r0hv]

There are programs that converts .bmp files to g-code. However, I couldn't find any that would satisfy me so I wrote my own :P You can download it at c4r0(dot)skrzynka(dot)org(slas­h)gcode

There are many kinds of stepper motor drivers. Mach3 works only with drivers that have step/dir inputs. The simplest driver of this kind (I'm using it) is based on two ICs: L297 and L298.

[HVdischarge]

oh, BMP is what paint uses to save isnt it?

i have no experience with G-Code, i have heard of it though.

:-D thanks.

Telling me what IC's i need has given me a good push in the right direction :-) Thanks.

[the2dipip]

how strong was that laser, and where would i get it, for how much...+kan i just use a CD copier laser...the ones in the CD disce thing....oh, and cool that you can speak like all languiges!

[c4r0hv]

The laser was 240mW and it was from 20x DVD-RW drive. Yes, you can use also a CD-RW infrared laser, though it would be max 100mW. But for engraving in black plastic like in this video it's enough.

[creativeboy1]

Hmm, can you make anything that you can see the IR Laser? i have one now but dunno if it really works :P HAHA

[c4r0hv]

Digital cameras can see infrared. You can use even cellphone camera. But there is one thing - If laser diode emmits light it doesn't mean that it works ok. It may be broken and act like ordinary LED dide.

[hrag500]

Wow this is a amazing machine! how much do they sell them for?

[c4r0hv]

LOL, what do you mean? I haven't bought it, I made it myself, so nobody it selling them.

[the2dipip]

my school has one of thous...and as far as i know they paid like 5000 euro, or more for it...but it burnd down... :'( was preaty awsome, hey, and grait work man, this laser is awsome!

[msichal]

Mam pytanko: czy ten filmik jest przyśpieszony czy po prostu teraz masz taką mocną diodę? Jeżeli to drugie to z jakiej jest ona nagrywarki?

PS. na maila wyslalem Ci pare dni temu kilka pytań, możesz juz nie odpowiadać bo spalila mi się dioda.

[c4r0hv]

Filmik nie jest przyspieszony. Dioda jest z nagrywarki chyba LG H58L czy coś takiego. Pracuje na prądzie 600mA. Moc tego modułu (mierzona) to 240mW. Dla porównania, moc modułu na diodzie z nagrywarki 16x przy prądzie 250mA to jakieś 130-140mW (mierzone). Na maila zaraz odpowiem, nie miałem ostatnio dostępu do internetu bo jestem poza domem.

[joshuaUnreal]

i use probotix electronic (parallel port , and drivers), in my own cnc machine, but I do not know how connect the laser in the port, or i need any circuit to do that?

[joshuaUnreal]

ok sorry, Parallel Port Breakout Board, how u connect to it, the laser turn on and torn off when it cut,. how u connect the laset to parallel port or needs any circuit?

[joshuaUnreal]

Hi karol, how connect it to break borad or needs any circuit?, can u explained that please.

[c4r0hv]

What do you mean by 'break board'? :|

[jrbpyro101]

what program are you using as the cnc software

[c4r0hv]

Mach3 and my "Laser g-code generator"
