Building a DIY portable Laser Engraver

[@EngraveMate]

That’s hands down the best thing I’ve seen this year

[@stevepreskitt283]

Looks like a cool project if you're on a budget and/or don't have access to a proper X/Y galvanometer head. I'd suggest three things though - 1.) use two mirrors instead of one and fix the mounts for both steppers - as it is, one axis is only moving the mirror's mass, while the other axis is having to move the mass of the mirror PLUS that of the other stepper. 2.) depending on the field size, it may not affect things enough to matter, but X/Y systems like this should really have an F-theta lens to flatten the focus across the entire scanned field. And 3.) use first-surface mirrors instead of normal everyday second-surface ones. Refraction through a second-surface mirror's glass degrades the quality of the beam.

[@trentonentwistle3586]

Hi! Are the google docs available somewhere else with the parts list and gcode? And the design for the circuit board? Thanks, very cool project!

[@Neptune730]

I like the system. The quality is pretty good for a 3D printed unit that has steppers instead of Galvanometers. You could probably get a little better quality with a first surface mirror as well. I am impressed though. Good job. I may have to build one.

[@Shadow__X]

this kind of laser control has been used for quite a while, and still is in machines like the laser pecker. Lasers mainly use cartesian gantries because you need to keep the beam straight when cutting

Holaa buenísimo!!!!! Excelent the home made litle pcb diy, Te Felicito por tu trabajo!!!!! Congratulation!!!! Saludos desde argentina 🤚👍

[@philgo2024]

Just a tip, don't use "normal" mirror (unsuitable for a laser) , look for a mirror in a paper scanner that you disassembled. I 'm not going to develop here but it's better.

[@haley8004]

The parts list on Google Drive says it's deleted? Can we access it somewhere else?

[@Mrmath76]

Hi did you find it?

[@jordidrago2239]

I´m very interested in building it, it is an incredible design. Could you please share more details on software? I know you are using Grbl firmware, but which version?

[@itsyaboipandaz]

Hi there! Like the laser! I was wondering if you could make a detailed video with the assembly and setup of this. I'm going for an engineering degree in the future and this would be fun for me to make

[@christinoccs]

THANKS FOR THE VIDEO CONGRATS, how do you control tension & current for the diode?

[@tvthiel]

Hi DAZ, amazing project, going to build it. Can you tell us what laser head you used?

[@jerosacoa]

Hi there... Some of the links don't work any more. Can you please repost them? This seems to be a nice design... I would like to replicate it if possible... Thanks for the nice work 👍

Remember to use proper safety glasses when using lasers, they are very dangerous and can lead to permanent blindness. Let me know what you would like to see me build next 👍. I'm not responsible for any eventual injury caused by this project.

[@DC-Nigma]

Do you have the code? I want to build to :-D

[@mkneubert]

Great video and awesome project! My parts list is ready, looking forward to the code video so that I can make my own one.

Hi, a new subscriber here. Looking forward for another video with firmware. I am planning to make this also. AMAZING project!

[@nova9054]

DO NOT BUILD THIS, It is dangerous. An unshielded 250/400 mW laser diode as mentioned in the parts list can blind. 250-400mW visible light laser diodes are classified as class IIIB lasers meaning they are capable of causing eye damage

[@frankhovis]

Has the firmware for this ever been released or is this now an waste of time thinking about making? I see the links to google drive for PCB and parts list have been removed so I'm guessing its now an abandoned project.

[@testantonio1]

Complimenti Davide!

[@RyLeedepressed]

Like a galvo with 100x the inertial forces

[@yikunwang7193]

thanks for the resourse

[@miniature_man]

you made my day

[@RobinGerritsen1995]

This principle I am also thinking on to make an additional tool to quickly switch between linear CO2 laser and galvo CO2 laser. The moving mirror will move the unfocused laser to the last lens and will burn on the material.

[@piotrsakowski9567]

this is super cool design!!!

[@goowatch]

Congratulations, very good project. I have a questions: Is the print not affected by the variable focal length between the laser and the objective? Do you set any software fixes?

[@kmyerslp85]

It is affected and I am positive he choose the optimal "range" so in the middle is slightly out of focus, outside of that is in focus, and further still is back out. Testing would reveal how much that affects quality to adjust for the best results with the lens. I was thinking if he could add a way to adjust that lens when the steppers hit their extremes. If he had the center of the work area in focus, when the laser starts hitting the limits of the area a mechanism would adjust the focus out to compensate. You could even have the lens on a spring to return back to the same focal distance.

[@larspregge6420]

Cool project.

[@dleivam]

awesome... the only problem I see is the safety issues related to a laser

[@omsingharjit]

How it manage to maintain its Beam focus because as beam moves from one end to other its distance vary from large to lass to large and so on it should be Account, so how it's implement here??

[@dchallenges9285]

where can i get the code?

[@myjet586]

So how do you overcome the distortion issue?

[@scr1ptery642]

Control laser with pwm, is much faster than a relay

[@StabbyJak]

Heya, quick question. It appears you're using 28byj-48 steppers, how are you dealing with the play / backlash in the gearbox? I would expect to see what appear to be missing steps in the engraving every time the motors change direction but that doesn't look to be the case.

[@Paint0nBrush]

I dont think a few missed steps are that much of an accuracy concern. the motor is like 2048 steps per revolution after the gearing.

[@xDarkBastix]

I printed all parts. But there are some information missing. For example that you have to print 2 small gear's. And the bearrings with 16x8mm are this 628? Is there a option, to use the normal laser modules from Ali or creality maybe. But all in all a great project and I like you skills, to do those awesome things. Greetings from Germany 🇩🇪

[@GabiBrawl]

I'm wondering how you solved the distortion problem, as a normal laser engraver goes on an x, y axis, and here you get a non fixed axis...

[@tructruc00]

What firmware do you use ? And can you provide links un the BOM?

Ok, I'll add them later. I use grbl, i will make another video about the software side of things or at least i'll make an article on the Arduino projects hub, i still have to decide

Running a laser that will blind you in a microsecond without an enclosure is a recipe for disaster.

[@iltiz]

waooo amazon project!!!!! im.a question.. motor stepper 5v or 12v?

[@EdFrench_uk]

You might want to use a mosfet rather than a relay to switch the laser- I don't think a relay will survive too many images

[@vigugaming9135]

What's the total cost??

[@eraldylli]

Looks interesting. But dont the stepper drivers need a 470 capacitor each? In any case, great job. Very interesting, different take on laser cnc.

[@DAZprojects]

I used a single capacitor for both the stepper motors mainly to save space and it worked perfectly fine

[@eraldylli]

@@DAZprojects Did you step it up to 1000uF or kept it 470?

@@nova9054 you obviously need to wear safety Glasses every time you use this laser

[@nova9054]

@@DAZprojects Look, your projects are cool and i do admire them, but I think you need to make it clearer that there are potential safety impacts when dealing with things like lasers. Some people who aren't trained engineers or have STEM knowledge try and make things like these and then can potentially hurt themselves. I like the project and I like your videos, but you need to make the safety aspect more clear. Sorry for the spam, but i don't want people getting hurt
