Isolation style toolpaths might be quicker than the raster and give you a ground plane too. Anyway it's excellent work, well done!

A lot of work went into this. Thanks for sharing. Its very clever.

Good work, with great results at the end - i'm very impressed!

you must be proud of yourself ..it's amazing.

Thanks for showing so clearly the performances of your machine. Nice resolution,and great engineering with contained vibrations,judging by result. I dont think to be able to do the same with my best press 'n' peel It would be great to etch the copper directly wit a powerful laser,but to me it looks dangerous as weaponry,1 wrong reflection and one gets blind before feeling the pain. Of course one could enclose the head,once everything works,but,during tests and adjustments everything could happen.

Beautiful man maybe slow but accurate and very nice resolution. That's what I call precision and high quality, very nice.

Very interesting indeed! A very good job it does too! Would love to build this as always prototyping. Ian..

Really fantastic resolution! Excellent work! I hope you will find a way to make 2-side PCBs with it!

a single video is worth more than 1000 words.

This is craaaaaazy. This is so insane that all of these parts for a machine like this are readily available these days

Wow, super Arbeit, sowas hätt' ich auch gerne zu Hause!

Awesome! Resolution is great, and 13 min is not that long. Good job! :)

Beautiful. I plan to try the same except with a smaller plotter.

Awesome job on the laser printer man :D

Nice work! I was trying to do mine based on spinning mirror prism from laser printer, but never got time to get it finished. It was based on Arduino and was reading BMP picture from SD card and projecting it line by line on the prism. Nowadays PCB manufacturing is very cheap and quick, so I abandoned this idea.

Not bad. Generally you have the best mechanical design I ever seen. It is even better than the most of commercial solutions. It looks so strong to make an drill instead of lightweight laser engraving diode. I suggest to work on the software because you still have some lumps and defects on the etched board. Also initial covering the PCB by plastic should be improved (consider spin coating). Some of things may be optimized but it is worth of effort, this machine have a really great potential. Microelectronics is possible (after change red to blue ;) ).

well done, professional, good resolution

Beautiful aluminum extrusions and other profiles. Nice crisp results. I cannot believe how small the 0201 SMD parts are. Not for hand soldering. I can do 0402 on a good day

We need more people like you!

so... it is possible to have the same result with classical methode? typon and UV light...

Hello congratulations for your project this luxury that chemists are using in the process thanks

F'ing BEAUTIFUL!! and Brilliant.

Great video but a little narration of the process would be nice.

Very cool! I am looking to do the same. What is the mW output on the laser diode?

It has very well turned out...

Grate job. Like it so much :)

Great ! Revolutional Method.

That is amazing, even would be for a professional PCB house.

Wow.. That is very very impressive.

Listening DIY's you don't need nothing like this, just need a print screen!

Very pretty result.

Excellent jump "Keep Lasering" :-) What spray you use on the PCB..

Well done sir ! very useful machine.

Soooo nice :) I must build it. Could you provide some information about diode and optics elements that you use it there?

Hi, resolution on your process is ridiculos ! wow i am very impressed !! I like this , thanks for sharing ! could you please share with us the power of your laser ? thanks

it seems you've used an atmega uC! ISR(TIMER blah blah blah) Amazing Work!

Can you please post the test pattern you used, I'm getting close to etching my first board and this would be a great tool to see the limitations of my setup. Thanks

Very good laser printer PCB.

Hi, have a questions: 1) what kind of plate you use? its the normal FR4 with or w/o photoresist? 2) what kind of kimicals you use? whay 2 baths? 3) in the first bath, the plastic tanque, what have benid it? its any heat resistor to heat the bath? (you do it yourself or this plastic tank can buy it? 4) where you buy the cnc and the laser? or you build it by yourself? thank you! p.s.: where you from?

Very nice, good work

incredible!

Well done!

Amazing!!!

Awesome work. I haven't understood very well what did you do with the lasser diode. Did you attack the copper part to remove? Could you tell more about post prosses?

Nice work! Great resolution. Do you think the laser can be controlled by parallel port as if it was a mill, not going line by line but following paths instead? Don't you think this could improve speed? Congrats anyway.

Regardless of anything else mention by others who might have a quicker way of doing this, the results of this printer speak for themselves.

Could you tell me a software that works (line by line) like that created by you and not working as a classic Mach3 and others. Maybe give control scheme of the laser. Congratulations on achieving !

Awesome!

Excellent job! It must have taken a lot of time and planning. Something for a kickstarter project?

Dude, this project is amazing! How did you do all those pcbs for the atmega and the serial converter? I mean, did you follow a tutorial or something? Do you have the projetct for this machine? I am planning to do a small homemade pcb milling and drilling machine, to have a fully automatic desktop pcb manufacturing machine. Any tips or advides?

0.2mm text is AWESOME!!!!!

Could you please release more specs, specifically the laser power.

Those Trinamics drivers are amazing... did you make them??

Could you maybe tell me some more about your etching process aswell as it seems to be two stage process. The covered bits seem to turn black in the bubble tank. Or is that just the lighting?

Very impressive.

Oh yes, the wonderful days of making your own pcbs. Unfortunately I don't have the time to do projects like this these days. I also never had the mechanical savvy to create something like this. Code, any day, digital electronics, some, analog electronics, a bit on a good day, mechanical gadgets, you don't want to see me try.

Whats it like on flexible pcb ,teflon etc ? Looks a damn site easier than the 90's when 0.05mm track gaps were about the smallest using resist and etching!

What solution are you using for the etching? Also did you use a uv laser to get rid of the photosensitive stuff? Or is it a normal pb

Very nice printer.

Thank you.

46x27.5 mm in 13 mins is slow? With photosensitive film/toner transfer + Etching agents + curing, that would have taken over an hour!.. You are making it over 6 times faster.. thats really fast.. I know you would want a faster result with the machine printing like a paper printer, hope some laser like that would be invented some day!

hacım mükemmmel olmuş. bakırı yakıyormusun?

Your heating elements, what are they - defrosters? And what of the published plans for this laser printer? Thanks for the video.

Awesome!!

Nice!

Great Job, But the Printed Circuit is working ? and i think you can do the itching on just the circuit without the Letters by printing them after itching

dammm...... nice job !!!!!

Very good. I wonder if a scanning laser could be made at home. We used to photo expose news paper aluminium printing plates using this process. I assume this would be much quicker than stepping a cnc type machine. Well done

E-X-C-E-L-E-N-T!!!!!

great work! what is the laser driver that you used?

the advantage of this way is working with two axis only

Great video. It is capable of making e.x microvias?

Is this laser a normal "chinese" laser ? I mean how can you make the dot so small ? Also how do you turn on - off the laser ? are you usung a transistor and a microcontroller ? Your work is amazing !!!

You wild!

Any info about the machine's HOME position and about aligning the PCB?

German overengineering at it's best! Digging the Trinamic drivers!

nice job, may I ask what etching fluid used for this video?

Good morning. Can you please write some information on the laser module you used? What is the wavelength? And the nominal power? Thanks for your attention.

very nice project , can you tell us how to make this laser machine

Well made! But i'm curious: 1.Do you take special cares for the acceleration / deceleration in the ends of the scanline ? 2. How do you create constant current (90mA) for the LASER during the "on" period ? I think that with a powerful resistor or a powerful transistor acting like resistor, e.t. linear. Possible ways for speedup (in theory): use N lasers, focused each exactly at next scanline so to do N scanlines at once. 3. How long is one point at the scanline ? speed of the head / point_time 4. Why the diode is operated with pulses ? Thus you expose each point with 50% of the power. Doesn't it work within spec. with constant current (e.t. keep it on when you need to expose, keep it off when you need to form a track) ?

А если прикрепить оптические линейки, китайские имеют разрешение 0,005 микрон в квадратурной дешифрации, Xmega поддерживает Qdac.

Thank's for your video. Ok, I afforded a TTS-55 from TwoTree. I think my definition ressemble yours. I struggle to see because you don't show a 0.25 mm track. But it seams that problem start around this size with your letters. Some chips need 0.25 to start from them for example the LT8705 power supply. With classic methods: i mean transparency laser printer and UVs etching, i can reach these sizes but there are other problems due to printers: 1/Linearity problems 2/Scaling problems. What paint do you use? Thank's. Jean-Yves.

Greate project Do you control the TMC 260 with SPI Interface or STEP/DIR interface? Do you publish this project with source ,a want to buil a smal version from your design. Thank you for sharing your video

very sick is there a tutorial on how to make this machine

I know this video is a few years old, im hoping you still read the comments, What are you using to convert a Grb file to solid black and what software are you using as a plotter ?

I can't understand what you do after laser printing.... what was in the first tank and in the second bubble tank.

You hand held the cam at the most critical part... lmao

What laser are you using? Would I be able to achieve that much detail with 5 watt focus adjustable Chinese diode laser?

Bonjour, superbe vidéo. Quels logiciels utilisez vous? Merci d'avance.

Greetings from Russia! Great job! Is there a description of the hardware and software?

great work! however I would be even more amazed if you explained to us how you arrived to this procedure, what software you're using! love it tho

how do you focus laser? using some optics?

Is the laser burn copper of the PCB? Why not just expose the lack on the PCB with lower optic power?

why u no vector!? how fine can you get traces and pads? also...damn dude, build a bubble tank! overall awesome though!

Good day, I am very interested in their software for the laser plotter. Could you please tell which you are using

Can you teach me how to make my own controller board using ftdi uart and configuring the micro controller

Nice! What kind of Laser is used here?

Was the photoresist used? I understand correctly?

Are you just using activating photoresisit?

Hello, I do have a Question, is it possible to cut 50um thick copper foil? would it present a problem to add kapton film? what is the power of your laser? 1W?
