Remember the 'Lasercubs'-project? The hardware changed a lot, but it is still alive. In this video I assemble and try out an EleksMaker EleksLaser-A3 Pro 2500mW Laser Engraver.The machine performs great after updating the GRBL controller and switching to the Laserweb software. - วิทยาศาสตร์และเทคโนโลยี
At 7:28 we see the proper safety procedure of etching PCBs.
And at 5:25, how to properly test if a laser diode is working.
Do not look into beam with remaining eye.
Hmm... I was trying to wrap my brain around how will this "laser etching" work, since it's not actually vaporizing the copper. Then it dawned on me that he's basically etching away a small grove AROUND the traces, so after the chemical etching those traces will be free and and independent from the rest of the board... very cool! :)
Totally awesome, and love the dry added humor as well. Very interested in the flex circuit designs in the future. Have been looking also for a perfect way to etch for ages. Remember over 30 years ago the old radio shack etch kit, messy and time consuming. Think I will give this a shot. Thanks.
*THE LASER IS A DEADLY LAZER*
The flexible pcb idea was great. I'll have to give that a try in the future!
Your humour is drier than dessicated coconut thats been left in the sahara desert with a sachet of silica gel and then eaten with an extra dry martini. I love it.
You shouldn't eat silica gel though. Says so on the packet.
:DDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD
Or drier than a semen stain on the bed sheet at a cheep "Motel 8".. tsk-tsk
literally all germans
Exactly, the guys German. Lol
Great working! By the way, please feel free to get back to us, if you will need Smart High Power High Voltage UV Lamp Ballasts, reference at www.uvballastsupplying.com. Thanks and have a good day! :- )
Thinking of making a circular slide rule, and I think this type of machine would be just the ticket for etching the scales on the moving parts. Thanks for the upload!
Wow, great video! Please make video showing the complete workflow. It seems to be one of the best lasered PCB's i have seen on youtube so far. Thanks for sharing !!!!
Nicely done, Marco!
I have to mention that you forgot to tell us that ... You'll be back!
We love you man. Keep it up
Just found this channel, I know what I'll be doing this weekend.
Very nice assembly and review, thanks for showing us.
The laser firing at start-up is because the control pin is floating while the Arduino is initialising (on my board at least).
A 10k resistor across the TTL connections on my laser control board fixed that problem for me. Not sure if there is a way to do that easily on a ready made board like that, but on my separate controller board, it was pretty easy.
I would use something like this module and slice it to the laser power wires. www.aliexpress.com/item/12V-DC-Infinite-Cycle-Delay-Timing-Timer-Relay-ON-OFF-Switch-Loop-Module-Trigger/32820660645.html
That way you could adjust the the delay time of the laser power to allow the arduino time to boot up.
same problem with my acan , first time was worried to see my wifes wooden desk with a big burn due at my disattention to power the device without usb plug connected to my pc... :-)
Excellent! Just the information I was looking for, presented well, clearly, and with a splash of humour! I've subscribed! Thanks!
Nice job, looking forward to more...
Great vid, thoroughly enjoyed your info, humour and general delivery. Liked, subscribed and notifications enabled 👍
Awesome.
Would love to see more experiments with the laser engraver and your Captain Tape©.
Nice overview. Thanks!
I thoroughly enjoy your style of vids and your humor. I'm out of my depths electronically, but glean much entertainment from them. Thank you.
what field of engineering does this fall under? truly fascinating stuff
Love you man keep it up. Great video and funny
5:05 - AYYYLMAO. Glad you kept your sight, good sir.
Great video content- wonderful narrating voice, really very engaging! Good stuff.
Ordered one with your coupon code I'll upload a video about my usage when it arrives.
One thing to try doing for custom flex is to try heating the -kapton- *koptan* tape with a heat gun, and also try having thicker traces and no big fill planes. And deeper "cuts"(more passes).
Hello.
Could you please explain again how did you mange to do flexible PCB? Step by step
Saying "peeling that will be the highlight of my day" + no change in voice tone = me having a good lol
Another inspiring video. Now I want a laser engraver!
Your dogs are really cute BTW!
Having just recently completed the build of an Eleksmill CNC machine myself I laughed when I heard the rooster crow in the background. A build I thought would take 2-3 hours, ended-up taking 6.5 hours including witnessing the sunrise ... on a workday!
Yah, that looks good!
Wow. Thanks for sharing😀👍
Your videos are so awesome!
Great stuff!
thank you for the video, I liked it
Cool video shot, thanks for sharing, keep it up :)
Impressive kit for the price!
Those flexible PCBs can open the door for people to create a ton of things. I never thought of using those two types of tape but that is clever. We have some of that aluminum tape which would be very similar to that copper stuff. Also some double sided tape that is remarkably strong for what it is.
+1 for the Husaberg logo! :-)
Excellent tutorial, and funny too :)
Taking this video as inspiration I decided to try this the DIY way. Lasercut the openbuild ACRO plates on a friend, buy some aluminum profiles, a cheap 500mW laser diode from aliexpress, arduino uno + cnc shield with a4988 drivers, some screws and motors and belt and pulleys and mount everything. Then I used lasergrbl and it worked like a charm cutting paper, EVA, cardboard, and engraving wood. It was all easier than I thought. Will try to laser some PCBs soon
Hah, 5:26 made me smile! (I am in the middle of binge watching every video you ever made)
Good review. Looks decent. If you improve the quality please do another video with details.
6:12 a masterpiece is born
I love your shot of firing the laser at the butane- LOL
Would love to see how you set up LaserWeb. I'm new to lasers and having a hard time trying to import something for it to cut.
My laser engraver should arrive the end of this month...Very good video.
Cooles Video marco
Great video!
Really like the thoughts of the flexible pcb. I'm trying to replace a foil circuit for an old car. It has a very specific shape with little hole cut outs to attach to the back of the cluster. Think this might do the job to etch the circuit and create hole cut outs?
Really nice!
Great video. Thank you. Will you keep us informed of what changes and improvements you make? I am an new subscriber.
Marco, you are a genious! Kind regards from east Germany! :D
Hey marco, I must say I really love your videos. Could I request a video on a good headphone amplifier, the components might be readily available with you already and the internet is full of tutorials etc.. but your explanations are very easy to understand !!
OMFG I laughed my butt off when you had the gas canister and your eye under the laser! Very funny 😁
Great video - v. informative and very funny. I love your your sardonic jokes.
Loved it very good !!
Bungard sells 0.125mm PCBs even double sided. They are basically sort of pre pregs for multilayer boards. They are not flex PCBs when compared to the kapton based ones. But they are flexible.
wow, that sure would solve a big problem. could you please share the link to banggood, thanks mike
Sometimes I wish I bought a kit for my CNC machine, it has been a work in progress for along time. This is very interesting
you can mount something similar buying openbuils ACRO plate set, some aluminum profiles, nema motors, arduino uno / cnc shield / a4988 drivers and an aliexpress 2500mW laser for about half the price he paid.
not sure if anyone has noted this but 445nm lasers us an array based chip tech so you can't get a dotyou end up the a very fine line or oval shaped Dot.
if you want a round dot use a 405nm laser as they have a true round dot. the dot can be made 3x smaller then a 445nm laser so a 1 watt 405nm preforms about as good as a 3 watt 445nm also with what your doing try swapping the steppers 0.9deg 400 step motors and Ti DRV drivers with finer micro-stepping you will lose 15~20% of your top speed but gain 16X the control over X and Y if you want the top speed back try using a 18~24v power supply for the stepper drivers only.
techmasterjoe thank you, I appreciate the heads up.
exact ....the burn on my wifes wooden desk has an oval shape :-)
Thank you
Marco,
This is a great video and NOT BORING. Keep up the great work. I built the Elekslaser and now am trying to get Laserweb to work. (under the eleks software it works fine.)
Laser web opens a drawing - DXF and it goes to the laser (grbl 1.1) but the laser doesn't turn on at the start of a run. and scaling is off. I am guessing that I need to send some sort of configuration to the laser. Can you share your configuration file and more importantly how to set it up. Everything have tried gives me an error or one sort or another
rror: 1 - ?G-code words consist of a letter and a value. Letter was not found. error: 3 - Grbl '$' system command was not recognized or supported. error: 3 - Grbl '$' system command was not recognized or supported. error: 2 - Numeric value format is not valid or missing an expected value.
So I am obviously missing something. -
thanks,
joel
He is good at reviews

purchased one myself.. tho i still havent managed to figure out how to get the traced image you use to generate the gerber in LAserweb
how did u setup eleks laser pro a3 with laser web 4 software...i want to know the settings of the laser web 4 configuration
hi marco.
this is the first of your videos that I have watched....have to say, this laser etching seems like a solid idea to me, man.
if any of you guys have any ideas how I can convince my wife that I need one, I'd be grateful ;)
thanks for sharing.... +1 to your subscriber list
@Marco Reps, what camera are you using? That thing is AMAZING.
Presented in a fine way. Thank you. I would never have attempted such a build had I not watched your vid.
I am a graphic designer not a C.B. designer. I don't think this would work to take the place of a good photo
emulsion unless you have any pointers. Again, thanx
Tom
I do that too when I peel the acrylic paper
omg you got me at 2:33
Cool as hell.
I don't know if you use this but I would recommend some conformal coating ($20
@8:37 The reason for the spacing difference on angled lines is the belt configuration running over the pulley wheels has too much expansion and contraction in the belt and wheels. Changing the belt to a reinforced non expanding type and changing the drive configuration to a standard arrangement will fix that.
I think the belts do have a metal mesh reinforcement inside. What did you mean by 'drive configuration to a standard arrangement'?
This design wrapps the belt around the wheels. the expansion and contraction of the wheels alters the positioning of the head on that axis. the belts should not have any source of contact except for the two pulleys at each end of the machine. this will give the least amount of positioning error.
Yeh, the flexing wheels! That sounds like a possibility. Thanks for the idea!
HI, will this work well if you put it in a vertical manner or inclined at an angle?
Marco, I have the T8 and it also does that damn tool power up on boot as well. Still, it was cheap and hackable.
Would it be possible to add a laser printer prism to the build to scan the laser over the etching mask? Can such power be deflected using prisms?
I gave this video a like just for the goat.
Dear Marco can you also laser in silver ? if yes how deep can you laser in the silver ? Kind regards, David
Very nice boot up state of the laser driver output... How can they get every other thing ok-ish but just completely disregard this obvious safety hazard!? ..what if there is a power out and machine reboots?! Fire hazard?
super video
1:50. Well done.
1:56 knob feel review channel reference :D
How many mils you think you can get out of it? And can better laser optics improve that?
Points for the Hussy'berg, represent!
Marco, how did you get Laserweb to trace the outlines of the traces rather than raster it?
Same question here. I tried Laser cut option, but I'm not sure it is ideal. Any update on this question?
@@moisesferber just use FlatCAM
Very cool! I ordered one through your link! Have you come across other methods for coating a copper clad board and using a laser engraver, other than the spray paint?
Not really, adhesive tapes / vinyl can work, but leave more dirt behind. I am making another video soon, mostly about mechanical improvements, but I might also include a wax spray product, that evaporates completely
What kind we need for pcb engraving. Thanks
Could you make a tutorial on how to mod this machine to use laserweb and make pcbs
Try to use flatcam we can set passes round for etching . and for the flashing problem might be arduino bootloader , you can upload program using programmer such as avr isp or arduino as isp to upload only program not bootloader.
This mehod your arduino will startup faster because arduino bootloader will wait for programming sequence about 0.5 second.
Where did you find this (1:17) instruction? I've been trying to find it for some time now with no luck.
Hi can I get some help getting red light from my board.
after i setup the laser
The question is if you prefer it over the 3018 cnc..?
Hello, can you please write me what spray you use to make PCBs? Thank you for answer.
it seems to me one of the axes is just slightly out of alignment. that could cause the diagonals to cut the way they did.
They gave him a pretty nice case for the parts...
@Marco - in 2020, any luck with using lasers to produce home-brew PCBs?
Thanks for the vid. BUT what was the spray etch resist, still trying to find a source of supply?
Pretty shure it was just black spraypaint
@@CarstenBe Yeah thanks, I should have gone through the vid again, it was obvious.
I have bought and just now built the 5500kw version of this. Curious to see how well it works with etching pcb's
A 5.5 megawatt laser? You must be directly hooked up to a fucking power plant.
wunderbar!
Yeah flex PCB!!! great video but I don't understand why not to use a laser printer? it can reach much higher accuracys and resolutions....
Nice, very nice. I definitely liked the parts with the innocent looking puppies and the Koptan tape.
Printing flexible pcbs by using kapton film seems like a great idea, if you can improve it. On the other hand, I still do not like the idea of these jagged lines all digital printers make when it comes to making pcbs. Or maybe, I just like straight lines to be actually straight rather than staircase-like. Somehow it doesn't feel right to me. Although I know in low frequency and voltage applications it's no problem at all, I have this nagging thought that it may cause reliability issues 10-20 years down the line (I have this thing about making things that last) especially when, upon maginification, it appears that the staircase lines are actually composed in fact by a number of horizontal segments which have tiny gaps in between (9:07), quite serpentine-like. I'm sure a CNC machine could be designed that would allow for the head to move in a variety of angles. It would only take only one more motor and one more rail (welll, actually two rails: one free to rotate on which the head can slide and one fixed where the other end of the rotating rail would be supported). Is there such a thing out there? I reckon it could be worth the trouble because in theory it should put much less strain on the vertical motion motors (and the whole moving assemblies) when printing diagonal or curved lines. Another advantage would be that it would print perfect circles of any size.
