Wanted to do something like this for a long time.This looks much easier and doable and also useful. You've inspired me. Great work! Thanks for sharing.
Wow this is very interesting years and years later. I’m going to attempt to build this with your video and hopefully pull it off. My soldering skills are decent but I’m a noob when it comes to resistors and capacitors etc.. very interesting thank you for sharing you work!
I have the feeling people who have the skill to take on this project don't really need a how to. The rest of us just just have a real hard time to follow your steps. O.o
nope. for experienced people, it's a great source of ideas. for newbs, it's a great source of experience. for the rest of us, it's great source of envy.
id104335409 yea basically just rough examples and ideas and idk I've yet to even see this thing in action. I'm not totally convinced. He Shows us a bender image and immediately cuts to an engraver cutting out a completely different image with the framing of it completely cutting out the engraver contraption.
Hello sir, Why my stepper motor is not continuously and moving in perticular axis while pressing the arrow keys and even movement is not content sometime it moves to Relatively large distance some times very little, sometimes not at all no matter how long I press the moving command keys or at any Step Level and sometimes the software misbehave ( not only this but other cnc software giving same problem), 1st i thought its Smps causing the noise I changed I even rapped stepper wires around choking ferrite but same issue so far it moves somewhat constantly but very tiny amount why? I am using clone uno with ch3 type installed driver? What causing issue
Great work! In grbl, I'm assuming you are using 256 steps for the laser power scaling. In this case $32=255 and not 256 as you've stated. The laser power starts from 0 and goes to 255 covering 256 steps. If you set that to 256 then you are starting from 1. Its not a major difference but when start laser power from 1 it means that its on even if its really really dim.
Do not wire the laser as it is in the schematic at 2:54 unless your laser has a constant current source built in to it. If it has'nt then the one he uses with the LM317 regulator should be used. Otherwise you will just burn the laser diode out. In the schematic it just has 12volts switched straight to the laser through a FET transistor connected to the 2 resistors (10K and 47ohms.) Pin 11 on the Arduino sends a small signal to switch the FET on and connect 12volts. If you are going to use the FET method then it should be switching the constant current source on and not the 12volt directly to the laser. Lasers are current hungry devices and they need a constant current to prevent them from drawing too much and burning out.
I think the LM317 is used to power it, but didn't show it in schematic since many people have laser diodes that have built in power regulator. Can you explain and provide a schematic how we interface the LM317 to power the laser and use the Mosfet for modulating the laser?
first thing I had no problem understanding you. but could you please give some more information on how you connected the motors. do you know what type of connector you use for those plastic and copper strips, and how did you go about doing
Hi guys! "How to Do" I'm following your scheme but I've got a question about. I saw how you use LM317 and where is located before laser diode but what I don't know and I am not able to see is where goes IRFZ44N before step-motor and it's driving me crazy! Thanks man! It's a very nice project, congratulations!
i took appart a dvd player (with rewritable capability) and it did not have stepper motor. it had dc motor (2 wires) and endstop and it did not have laser diode. it had holographic unit. (apparantly a combination of laser diode and optical sensor. it is a flat package with 10 leads)
@@abdoustube survival lasers, od rating and wavelength depend on what you want I got mine for like $40 usd. Go on lpf and ask if you have any other questions people on that forum are gods.
Thank You for this video. This is here bit.ly/2zMIolU I bought one! :) Have a nice day! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-fi57H_X-AcY.html
i mean you have to be a bit creative, you could basically use anything with a linear component, printers, scanners, whatever, basically take 3 of them mount them onto each other so they can move in 3 axis and bobs your uncle.
Putting “(I am being sarcastic)” show that you think that what you said could be taken as not sarcastic which shows lack of selfie confidence and also that you think that you are one of the few that thinks this, however you are wrong
Could you use this to cut trough masking tape for making small stencils,or could you possibly use this with UV diode and UV 3D printer filament and essentialy make your own 3D printer for less than 100 dollars?
Hi friend! Can you help me, please? Can I use your grlb software and laser grlb editor at arduino mega 2560 and cnc shield ramps v1.4 and 3 stepper motor? Is it possible? Are they appropriate for my component?
Great job ! A bit fast, especialy on the software part. It's inproper to pretend engraving with DVD drive as it suggere that you are using the laser from the DVD. I'd like you to tell which laser at which price it is you suggere to buy. Thank You !
Hey Konstantin This is a really cool project you made there and i would like to try to do it too but i have a few questions i hope you or andybody else could answer: 1. Whats the length of the alumminium angel you cut off or does the height not matter that much? 2. As you already told someone else in the comments you could get rid of the LM317 with the heatsink when you use a 12V laser diode driver, could you recommend any driver or should i just buy one that supplys the needed current? 3. How did you know how you have to connect the stepper motors to their drivers? In the drawn circuit it just shows where each coil has to be connected to the driver but how do i know where the motor has the connections for each coil?
1. Depends on the size you desire and the other parts you are using. 2. Pretty much yes, one that supplies enough current. I still recommend looking at data sheets to make sure it works with your laser 3. Read the data sheets for your motor and controller for more information.
Ok, thanks for your answer! I also searched for some answers online and found this if anybody else wants to know: 1. I think I´ll just take what I think will fit for the weight of the dvd drive and the laser to hold it stable 2. As somebody else mentioned in the comments a buck converter is also a good way to convert 12V to 4V the voltage and they are pretty cheap 3. You can easyly find out through searching "DVD drive motor connectors": electronics.stackexchange.com/questions/134930/wiring-up-a-4-pin-dvd-drive-stepper-motor

We learn so much from videos in fast forward. Do you really think someone could build a laser engraver following your video? Slow it down. Explain each step.
IS IT SO POWEREFUL THAT CAN BE ENGRAVE GLASS LIKE STAIN GLASS WORK MAYBE BY ADDING X4 OR BY MOUVE VERY SLOW CAN YOU TEST IT AND TEL US IF IT IS POSSIBLE OR NOT
Ohh yyeahhh!! Dude, you are a boss!! I've had 3 optic carriages lying around for such a long time, intended for this purpose.. I decided ill make the mech/elect setup in whatever way i feel like it should be. But since I don't have much experience with arduino, i keep procrastinating this project because i was afraid that I'm going to have to force myself to sit thru a few hours of tedious RU-vid tutorials made by some slowly explaining automation geek that feels like he needs to talk about every damn nut and bolt he uses on this diy build for 5 minutes each hahah... BUT NOO!! No need for that boring stuff at all!! This guy just makes the whole project exactly like i had in it in mind! and managed to condense the whole thing from start to finish into just over 8 mins of properly focused, correctly angled, clearly visible, nicely edited, high def video!! YAY!!! I'm so excited now i feel like getting started right away lmao, thanks so much for sharing this awesome tutorial bro! im subbing for more, 👌👌👌🔥
