In this video, we will build a super portable and precise Arduino-powered laser engraver. We will explore a new and unusual way of building these DIY machines by using rotational axis instead of linear ones, achieving great precision and unlimited range in a surprisingly small package that can be powered simply from a power bank and controlled wirelessly using a smartphone.

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!

@Shadow__X Год назад

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

@itsyaboipandaz Год назад

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

@Neptune730 6 месяцев назад

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.

@RobinGerritsen1995 Год назад

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.

DO NOT BUILD THIS, It is dangerous. An unshielded 250/400 mW laser diode as mentioned in the parts list can blind. This has no shielding and can cause blindness. 250-400mW visible light laser diodes are classified as class IIIB lasers meaning they are capable of causing eye damage

@fasttl Год назад

What sort of speed can be expected on thin wood?

@josephquinn6060 Год назад

this type of design has the potential to be very fast, but with the limitations of having a smaller work area, due to the focal length of the laser. Besides that this is a remarkable machine, especially because of the low cost and portability. Of course you won't be able to take full advantage of the speed of this design, unless you upgrade to a much more powerful laser module.

@Shadow__X Год назад

many commercial laser engravers use this and they are insanely fast, they scan so fast you basically just see a line

@stevepreskitt283 3 месяца назад

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.

@omsingharjit 6 месяцев назад

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??

@philgo2024 Год назад

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.

@juliocesardemoraesbarros5585 Год назад

Hi, how did you control de focus!

@goowatch Год назад

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 Год назад

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.

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 🇩🇪

@Ahmed-ic9ft Месяц назад

Hi you still have the stl?

@StabbyJak Год назад

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 Год назад

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.
