I'm impressed and I like those leds too. I'm sure you can fix the spacing issues with some little editing. THANKS for not forcing us to listen to music! Machine sounds are better.

It is incredible as it paints a pen, never fails. Greetings

This is the most amazing thing I've seen all day!

Impressive work. If I may make one suggestion it would be to keep the Z-axis cable clear of the plate. But it works out fine. In fact, it was a joy to watch; you should be proud of what you've achieved.

Nice idea! Since this is holding the pen perfectly vertical, you could ram the felt tip almost all the way in to reduce the surface where it can dry out.

I can watch this endlessly

Back in the way distant past, I used to work with flat bed plotters which work in much the same way as this. However, the problem with fine detail always was that, over time, the nib of the pen 'splayed' and became wider than it was originally which, when used like this, would lead to more occasions when traces joined undesirably. My thoughts here are to, instead, prepare the entire board with a resist and, instead of using a pen, using a sharp scribe point to scrape etch resist off to expose copper for later etching. Of course, the software would need to be altered to scrape trace outlines but for all but the finest detail (which would still need photo transfer) it should improve results. That said, absolutely awesome results in any case, and I'd be happy to have your machine on my desk now :)

Really interesting project buddy, Even tho it has some complications like random error at 0:35 but this is something worth making. I will definitely enjoy a "How To" on it. Thumbs up for this device mate

Your project is simply excellent! Well done!

Wow. really nice work!

Very nice. Looks like I found another project to try.

If you could possibly give a list of parts or make a video of how YOU made this one, it'd be much appreciated. This is one of the better ones I have seen.

Well done my friend, i like it because it's little but very precise as i can see.

Amazing, nice creation. Nice clean design.

Simle and easy. Good job!

sonho de consumo, vou tentar montar um, obrigado

So smooth, very good!

Greetings. I'm new to PCB design/making, but it is my understanding that, especially for HF circuits, you really don't want right-angles in your traces. That's why there are 45-degree bends in commercial PCBs. You may want to adjust accordingly, unless you have an issue with mechanical fidelity and not being able to guarantee simultaneous X/Y coordinate movement (e.g. moving the pen at an angle). Aside from this minor issue--which is likely tied to the design itself--this is a great project!

u make it look so easy

first thought: "wow thats really cool"

Awesome work. I would like to complete one my self, maybe near future.

I love it!!

Wow I like so much

Hi, where can I find the project for the structure?

The Most Satisfying Video In The World! I swear :D

subscribed, waiting for the tutorial :)

very beatiful..great work

How cool is this 😮 thanks for sharing your video.

That was really satisfying to watch,

muy interesante ... felicitaciones por ese bello proyectó. saludos desde Ecuador

Is there a link to the STL's? Thanks :-)

Congratulations, you made one very useful device, which is in the same time very cheap :) The idea of movement transfer between steppers and linear moving parts is great, I thought before, almost unreachable with good accuracy using this 28BYJ-48, because this stepper has almost 4° degress circular clearance. I would like to ask you, how did you solve this problem, is that solved in the GCODE generator or mechanicaly (with reducing circular clearance in reducer of motor)?

Excellent work man.

Amazing!!!

Brilliant. Way better than messing with iron, foil and laser printer.

Really nice, and simple, and fast ! Well, maybe not so fast... but inspiring nonetheless

Congrats with achievement of making such a device. Question, how good/bad is usage of a pen? Are there problems, errors related just to usage of a pen? Thank You!

Ravi. Thank you for posting this demonstration. What kind of pen is it that so reliably and so fine?

Excellent project

Awesome machine, do you have any shots of the completed pcb, what do you use to etch the board?

Amazing project

A question regarding the pen: How do you configure the pen tip size (e.g. different pen tip)?

Do you have the layout of the pieces made in 3d printing? Where can I get it?

Wow, this is a very good idea!

Beautiful. Printing only with a Staedler.

A question here: How do you configure the pen tip size?

Mantap nih bikin pcb langsung cetak

Perfect !

Excelente gostei muito, teria como compartilhar conosco o esquema deste projeto?

Nice project! A question: How did you make it work with the nylon strings? I've tried, but it didn't work (not enough friction).

Can you please detail out the parts used, what rods and bearings, what are the sizes of the bearings and where you got them.

Hi, Awesome project! i've made it but i dont exactly get how i need to code the arduino and how i have to do everything. Can you help me?

Very good, Congratulations!

0:35 i hate it when this happens

Servo for the code M - i can't find it anywhere. Any sugestion ?

well done really amazing

sir, can you tell us how do you synchronize the servo to the movement of x and y axis.

Thanks For Everything

it's good if there is tutorial from beginning to the end, what parts needed, how to assemble those parts, how to connecting the wires, and how to run the software (the most people struggling with it) because not all people smart and can understand just by watching this video (me include of course). knowledge it's meant to be share

Really interesting this mini cnc (with guides retrieved from the printer). One question: after bathing in Ferric Chloride ... the pcb hole handles them either directly from the cnc (through a dedicated software) by applying a mini spindle? I really care about it. Greetings.

Hi! Good Job! How is the brand of the pen used? How the plotter knows the trace width of pen ? Thanks! Thanks so much!

Great video Ravi but I need help with the CD ROM stepper current because mines don`t have any description on the cover and therefore I just can`t calibrate them with my A4988 Pololu drivers.How can I find out the right values?.I`m affraid if I assume some values these don`t work properly or going crash.

Hello, congratulation to the project. Where do you bought the linear guides?

Openbuilds could supply all the Cartesian mechanisms, and a MEGA/RAMPS board driving steppers would bring it all to life. What I'd like to know is: How did you generate the G Code, and, what pen can lay down ink that consistently?

I want something like that for placing solder paste on the BGA pads.The pen can be replaced to have a syringe with solder paste?

very nice construction, congratulation! just something I am looking for, it can not be since you buy as a kit?

hello Ravi, amazing job ! i wonder what shield driver have you used and what program or how to learn how to program this ?

On your schematic you only provide the Arduino and not the mechanical build? Please update... Thank you

dear ravi it is amazing , please tell me how you are connecting stepper motor to slide i.e. through string. does it slips ?

Where can i get linear screw thread for this motor? Its for my mini cnc plotter project.

seu trabalho ficou muito bom, eu tbm estou construindo uma CNC usando sucata de dvd.

hello, in my project the pen goes on the side of the trail, how do I make the pen paint on the trail. thank you

Awesome projects lovely

I was inspired by this sir, that is why i also made my own version @

Amazing! :)

CAN YOU SHOW US THE pcb AFTER ETCHING?

I need that now...!!!

Very good

Hii Buddy, Can you please tell me complete process how did you did this I want to develop my own PCB making device

I would like to build a machine like yours, You could tell me which parts make up the project and where to buy them I mean the electronic parts engines and others. And the stl needed to print the machine

Please can you make a video about GCode, how to use FlatCam. How to configure it for the servo. Since this is the hardest part. Thank you

Excellent JOB

Nice! very very. I love it .Thank you.

Muy bueno hermano! Bien casero.

Hi, good job, which software do you use to generate nc file?

hello, very interesting i want to make this one, could you give detail part of hardware, please? thank you

Hi friend! Would you have a schematic list (pdf) with the measures of the parts? Thank you

Magic!

Hello.This is usual marker or special? How this marker picture holds versus FeCl3?

Hi, I have problems with the configuration of grbl with respect to the steps per millimeters of the engines 28byj-48, the required measurements are not the same as those that try to draw the plotter. Could you give me your grbl configuration? Thanks a lot. Greetings.

Do you have the entire step-by-step project for the assembly and execution of the project? How can I make it available?

Hi, wonderful project P \ where can I find the project for the structure?

fantastic！

Excuse me, I have a very similar one and tried to make me join the plates as well as you but I have not got my problem is that each track makes me the sides of the track does not make me a single line per track like yours, could you tell me how have you gotten this effect, I use gcodesenter to control the cnc and to make the designs I use proteus and then I pass the exported image to the inskape and he gives me the code g, however, he does this instead of giving me a single line what do I want help please?

Compliments! but could you show what software you used and how you came to plot?

question: where did you buy the rods ? i cant see to find any !!

Goooood! I have the same stepper motors, about 10 of them. It heats up so fast within 10 minutes, I never thought someone can make use of that motor. I wonder how long this machine can run without damaging the motors.

Muito legal! Incrível!

Чудеса, да и только!

Very simple way. I like it
