A raspberry Pi controlled plotter! looks so cool and easy to make. great instructions by HomoFaciens
I love it you dont put music on for soldering and you explain everything
Thank you so much for sharing, very amazing and beautiful,
I simply love the stuff you come up with. It's made of spit and bailing wire and it is the highest form of engineering.
Fred Mull Sorry to be picky, but "baling wire" is the stuff used to tie "bales" of hay together. It is not useful for removing water from a boat by "bailing." ☺️
Excellent! Very thought-provoking... thank you.
Okay, the homemade H-Bridge is just freaking awesome! (@1:58 in the video)
+MrWaalkman ...more freaking h bridges:

such an amazing tutorial based introduction. Very infformative speech. Keep it up. and congratulation on this project.its super cool to build our own machines
***** Yes, there is nothing better than watching your own machine doing some work for you.
Love this! What a great idea.
This is amazing!
Great job!
Beatiful. Even it can draw over any surface. like for you
Seems like much fun :)
This kind of stuff is what i plan to create in the future but as for now im just learning to code.
I was planning to buy a Raspberry for this and im glad to see it works just as i was hoping.
Wish i had more knowledge of electornics, im sure ill burn the Raspberry eventually hehe
I particularly like the write-anywhere feature of this plotter :)
+Claudio “Hütte” G. Yes, that's what many people fascinates when thy see this machine drawing.
I love it! Just found a scanner+printer device and currently dismantling it to get the cool parts. I'm planning on building something very similar to this but on a larger scale. Gotta love how things that are thrown away can be reused to make cool and actually useful stuff. Such a device can easily be adopted to be used as 2D plotting device for small projects.
+rbaleksandar Yes, 35x35mm isn't much for plotting projects, thus a larger machine would be more helpful. Hope to see your machine soon.
HomoFaciens
I hope so too. Epson printers/scanners however seem to lack labeling on some of their motors and/or datasheets completely. Will have to research quite a bit...
You can drive your little step motor by a 12V source, just by adding some extra components (current limit res, opamp, clock generator ) or connect your L298 dual bridge with its driver L297, your motor will spin faster with less step loss. Great work, nice project BTW (sorry for my bad english)
Anh Tú Nguyễn That would be the overkill for this plotter project since it is more a toy than a tool. There will be more plotter / printer / router projects. I will consider your suggests when building one of these machines - thanks! Currently I am creating a larger one with a router. I will use normal DC motors with the L298 dual bridge, turning them into stepper motors with photo sensors - stay tuned. (There is no need to apologise for your English it isn't bad)
As a native Anglophone, I can attest that your English is fine.
Nobody can tell me that this guy does t sound like Arnold Schwarzenegger
+AIO inc. Can't help, but those Schwarzenegger always tries to imitate me.
HomoFaciens
ikr
+AIO inc. the i'll be back nailed it
gyoussef
No, to da printer:
th-cam.com/video/IgU__c4NgrM/w-d-xo.html
Well he does say ''I'll be back'' right at the end.
I just hope he does a video about cooking with fresh herbs and shouts ''get to the chopper''
Excellent work!. I want to try this product.
박가이버 You've got to build one by yourself to try it - it's not for sale.
very Cool HF! enjoyed this very much!!!
Wonderful, many thanks for sharing this.
+Marcus Hulme You're welcome!
Great piece of lateral thinking there. Another job well done!
andy parry ...it's just the prelude of my next video about a big plotter that is currently under construction.
Cool. Would be interested in that. If in the future you could change the pen on your big plotter for a router or a laser cutter, that would be epic.
andy parry Using it with a router is indeed the main intention of making the plotter bigger. I have cut a gear wheel from 4mm plastics today, but the result wasn't as expected, so I have to do an overhaul of the mechanics tomorrow. Since power lasers are dangerous I won't treat those devices in my videos (yet).
Working on my building my CNC with an arduino. Thought I might have damaged my stepper motors as well. I should have just clipped off the ribbon instead of removing it. but it looks like they are still functional. Waiting for motor controls to come in the mail to continue. Wonderfull series you have.
+Maltux1 Thanks!
nice project and well thought out
+Colin Smith Thanks!
Excellent work!
Very inspiring ............. keep cool work guys ...!!
+Dedy Yasriady Thanks, but it's a one man show.
This is awesome !
YOU ARE A GENIUS !!!
+AdryannMC My project is meant to share the ingenuity of technology. Learn how to create your own awesome machines rather than just admire those of others. It's not too hard to become a maker ;)
+HomoFaciens im inspired by u. may i know how do we insert the images? is it hard to chose which only suits?
Heng Amirah
I have inserted a quick Hoto in the software section of the project page:
www.homofaciens.de/technics-machines-plotter-cdrom_en_navion.htm
Awesome Job!
Excellent !! Very good explain
I like how that laptop looks, very classic looking
+scottaw1981 Unfortunately the laptop broke down. It was old when I got it and now it's time seems to be over...
It's last appearance was in the video about CNC v2.0 (forward to 13:40):
th-cam.com/video/p1PwYa4Fdqc/w-d-xo.html
Thats a shame
love the design
Excellent educational tool.
...mission successfully accomplished!
Genius. I'm so glad that he spoke english and not german, so I could understand what he was saying. I laughed out loud at the end when he said: "I'll be back." lol !
Very good This CNC machine!
you are a genius
+Amin Mohammed Thanks!
+Amin Mohammed Ideed he is! Ill try this for sure, I was planning to do it with an arrangement of metal threads and 2 motors for X and Y axis, but your solution is clever with old CD readers.
Alexandro Giles I m still at basics operating relays this is far fetched for me , I have been doing more on software side this is exciting
+Amin Mohammed I will combine hard and software in future videos and chapters about physical computing - stay tuned!
Flight simulator? Wow!
excellent, very nice, thanks for share!!!
Nicely done
Great stuff as usual
Congratulations!
I love this guys accent.
...it's German-English as good as I can ;-)
amazing works
+Kuuzka Thanks!
very clever, would not have thought of tearing apart some old cd drives for that, now i'm thinking how can I use them. :)
Kirk Nelson I am not the first tinkerer that has done that mod, there are many videos on TH-cam doing (nearly) the same. However, the reasons why I have made another video are: I wanted to demonstrate the building of such a great tiny plotter more precisely than in the videos I have found and this is an introduction to my next video. I am currently creating a larger plotter made of simple tools and materials available in a DIY store. Stay tuned!
thanks, I'll be looking for to it :)
So good!
Great! Awesome! Fantastic!
+gi-won Gong Thanks!
Особенно развеселило самое технологичное место - чёрная ниточка))))
+Обычный необычный Thanks!
that's nice, Man !
am gonna do it! I have just got 1st cd mechanics from old pc.
+steve lp Unfortunatels not all CD drives have a stepper motor. Good luck for finding a second one!
great sir you are genious
He Men, is Joselito inventor, congratulation
How would you have such a crazy idea ? Keep it up :D
+irlrp
My latest crazy idea:
th-cam.com/video/IPClUTfKB-o/w-d-xo.html
...more of them are still in my brain...
Love ur idea creative
wheres the love button !!! awesome work !!!
+Brett Pillemer Thanks! There is no love, but a "Donate" button on my project page:
www.homofaciens.de/technics-machines-plotter-cdrom_en_navion.htm
magnificent!
Nathan GUO ...no, it's not a large machine ;)
Awesome! Are you controlling the plotter limits through code? Or do you have some sort of sensor indicating travel limits?
+Paul Sullivan If there were end switches, I had shown them in the video. Those tiny stepper motors cant cause damage if they exceed the limits. The software scales the images to the maximal move length of the motors (220 steps).
hello very cool project, nice tutorial ! just one question: can i use the L293D ? thank you
+rafik lmd Find ot what current your motors draw at 5V and have a look at the datasheet of the L293D and you have the answer.
That is very clever.
Thanks! I wasn't the first tinkerer using old optical drives that way. I simply changed the mechanics in such a way that you can draw on any plain surface and used a Raspberry Pi to control the plotter.
canggihh,, inspiratif.
Humam Fikri ...strange language.
genial!
I tore down a bunch of old hard drives to scrap out, but I kept the stepper motors. This helps me know how to find the coils. But does anyone have any idea how to get the ones out that are molded in the drive housing? Will I just have to break the housing?
I respect people like you who make things out of nothing ....
I wish we can communicate and have you as friend ... by the way are you german
+frenso shaker Yes, I'm from Germany. We are actually communicating, aren't we?
HomoFaciens sort of .... am glad to know persons like you ... thank you
wow it was great
it's a miracle !!!
+Nam Nguyễn Đăng No, just a tiny machine!
yeah but it is interesting haha :3
Hello HomoFaciens. I try to achieve this project. Sadly, I soldered solid wires to the tiny foil of the stepper motor, so the foil stepper motor got off it's place and I now have a look at the internals. I'm aware that, as you said on your website, "Don't remove the foil at the pins, because you will very likely also rip the copper wires off the pins by what the motor gets inevitably destroyed!" but I wish to make it work again. Since I have access to the coils maybe I could solder wires and use these to control the motor or all hope is lost ? How would I proceed ? Thanks a lot in advance.
Well, if you find the 4 "ends" of the coils and solder wires to the H bridges it will work, but those coils are wound with very thin wires...
I can only see one or two wires. I guess i'll have to do it all again :( thanks for ur advice still. BTW shipping fee are expensive and shipping time is long here, and we don't have makerspaces or other dumpsters services where you can ask for broken things. I guess I'll have to ask my friends for broken cd:dvd readers
cool !
Your dead-bug h-bridge gets a thumbs up on it's own, lol. ;-)
great!!!!!!!
Молодец!
+Обычный необычный Спасибо!
excellent ;o)
Is the "green" PCB is step motor driver? It seems that the steps is too big. Need more precise driver with 1/125 or 1/250 microsteps.
And which software you use to control the machine?
The driver is a L298N double H bridge with no microstepping support. This machine is just for fun, thus the rough resolution doesn't matter to me.
hi i have the same pc, how can a install lubuntu? I did a thousand tests but I did not succeed...wonderful project
You won't get a lubuntu distro for this special ARM processor. All I could find was a basic Debian install that is no longer supported.
Amazing work !
Could you please tell me wath the computer is ? I would like to find one like this ;-)
Aymeric Ratinaud It's a noname device with a WM8650 chipset that normally runs Andriod. It was very hard to bring Linux on it, thus I don't recommend buying such a "laptop". Search for a reasonably priced laptop that runs Linux.
HomoFaciens haha ok ! thank for your response and advice
Genius
Hastala vista, baby! I'll be back!
+JaPeKePaJaKe ...meanwhile I have been back multiple times. My latest video is about CNC v2.1:
th-cam.com/video/tAusnFPgOcA/w-d-xo.html
nice
How can I use an Arduino board instead of a Raspberry pi to do the same as above? Do you have the Arduino code for it?
Write your Arduino software. I haven't done so, because it runs nicely with my Raspberry Pi.
I will teach how to do coding in a coming series about "Physical Computing" on my pages - stay tuned!
Can you please tell me, how did you made the platform? I mean 2 motors together? I used nut bolts, but they kept spinning. How to stop spinning? I used glass glue. But they works less.
Have a look at my project page to see details of the construction and the used software:
homofaciens.de/technics-machines-plotter-cdrom_en.htm
super
wow sweet
anyone know what software can generate gcode to print in horizontal lines, like at 5:39,
i need my plotter to have a unidirectional drive on the y .
Hey one more question, is it possible to use a DC motor for the one that holds the pen or not? Thanks in advance.
It's a DC motor that drives a servo...
You'll need either an H bridge to turn the motor into both directions or you can e.g. pull the pen up by the energized motor and let is fall down through gravity after cutting the motor energy.
How did you made the pen holder? If you attached that using a screw, why doesn't it moves right and left?
It's glued on the laser head of the carriage. You can get the build instruction on my project page:
homofaciens.de/technics-machines-plotter-cdrom_en.htm
hi there, very good tutorial but will any L298N H-bridge work? i really want to build one, with correct parts!
+aran everitt I guess any board with a L298N chip will work, as the stepper motors of the optical drives consume just 500mA and the L298N chip is for a continuous current of 2A.
thanks man, just ordered the drives for dirt cheap. I hope they contain steppers haha. on the other end of things, if I can use CAD software to model the thing I want to output, I could even mount a dremel tool so it can engrave or cut out!
regards
Aran
The software I have written needs scalable vector graphics with all paths turned into polygons. The weak steppers of the optical drives won't overcome the side load during engraving work. Have a look at my CNC v0.6 which is under construction:
www.homofaciens.de/technics-machines-cnc-v0-6_en_navion.htm
thanks man :)
+HomoFaciens I'm glad you pointed that out, as I had the same thought as aran! your videos are great for showing what can be achieved using relatively simple techniques and mechanisms.
where can i download this software used on the build? i want to use this on my Nano or UNO via Windows 8.1 links will be great!
Frank Lopez Have a look at the project page:
www.homofaciens.de/technics-machines-plotter-cdrom_en_navion.htm;
...and replace Windows by Linux ;)
When using an Arduino you will have to make major changes in the software code that is written in C.
Terminator talking down how to build a plotter :)|))
...Fritz you speak very good Germinglish
+Jurgen Dorries Thanks, Tommy!
I'll be back...with a Steppa Motah!
Heath RPi ...or with a terminating robot if you don't stop kidding around with the master cyborg...
Great job! Is the code available?
Thanks! Did you have a look at my website as I tell you in the video? The link is also below the video, but here again just for you:
homofaciens.de/technics-machines-plotter-cdrom_en.htm
@@HomoFaciens Thanks! and Happy New Year. I have built a 10:1 encoder and the simple code I'm using counts fast and accurately. However, I have timing problems when I combine the code with other tasks, like controling the motor or with button debouncing functions which use delay().
Instead of delay use a loop that reads the encoder state. like this:
for(int i = 0; i < 10; i++){
read encoder stuff();
}
respect
Moustafa hamoudi Thanks!
Thanks
+Shashika Gayan You're welcome!

... your home built H bridge even makes you seem like a robot.
+flyingtoretilas I have build more H briges:
th-cam.com/video/SsB_ezlict4/w-d-xo.html
What about using a laser from a dvd drive instead of a pen to cut cardboard using your device? What are your thoughts?
cheers colin vk2jcc
+Colin Christie This is a machine for beginners and beginners should not play with lasers.
What kind of H-bridge did you use? I mean what serial number so i can find the same and buy it :).
+Mats Pettersson L298N boards (commonly available). Have a look at the project page for more details:
www.homofaciens.de/technics-machines-plotter-cdrom_en_navion.htm
+HomoFaciens Thanks!
Can you please tell me what servo you used? What model?
Simply look for a "micro servo". Mine wasn't an expensive one. It's with plasic gears and works fine.
Einfach schlau!.
Cus band ...und das Video gibt's auch auf Deutsch: th-cam.com/video/UqOYlB8f48k/w-d-xo.html
where can i buy bridges? please some link :D
+steve lp Simply google for L298 bridges and you'll find countless devices to buy.
That draws better than me.
+Fatmeatball ...and much better than me ;)
can you do or recommend a Linux tutorial? I know there is a lot out there but would like to hear it from someone like you. :)
+gigicaly Thanks, but I have (currently) no intentions to make a Linux tutorial. There are many good ones in the web. The one you find best depends on the Linux distribution you are running. Ubuntu has a large community with tutorials, HowTo's and fora.
Just curious - what is the manufacturer/type of laptop at 4:16?
It's a cheap chinese plastics laptop with WM8650 chipset and no manufacturer label ;)
Yes, the software "support" for those laptops did not exist...
...gladly I found a (non perfect but working) Debian image on SlateDroid. The Lander camera in my www.RoboSpatium.de still works with that laptop.
how do you run the program on the pi ? can they run C files ?
Have a look at the project page to get answers:
www.homofaciens.de/technics-machines-plotter-cdrom_en_navion.htm
I can't find sellers for a 10 watt laser diode to cut acrylic sheet of 5mm thickness to circles , want to use this CD cnc mechanism to cut acrylic
If you can't find sellers of a 10W laser diode, it's better not to risk an eye. These devices are very dangerous!
There are fake diodes on eBay etc of 10mw faking it as 10 W diodes, at my place idiots run workshops using laser cutters but they take production orders , earlier I used to take the acrylic sheet to lathe machinist
8001maya
You should not by 10W laser diodes from sources that don't grant the properties or where you don't get your money back if the device you get is scrap. Always buy from shops located in your home country.
hi, another question, my rpi h bridge is marked with A1-A, A1-B, B1-A, B1-B. do i connect both the A's to pin 13, 15 and both B's to pin 21, 23? thanks.
Aran
+aran everitt Have a close look at the datasheet of your bridge, or simply try to connect them that way and see what happens. If A1-A... are the INPUT pins of your H bridge, there is no danger to harm your Raspberry, but it could be fatal if A1-A are the OUTPUT pins!
thanks again, one final question... right lets say i connect the right pins to the right connections etc do i power the raspberry pi with the micro usb and NEED to connect the +line from the battery aswell or should i NOT connect both battery and micro usb to the pi at the same time. thanks :)
Regards
Aran
+aran everitt Don't connect both to a power source. If you connect the Pi to a USB power supply, you should NOT connect pin 2 to +5v coming from the battery (via the 5V regulator of course).
ahh thanks man. i have built it now. all i need to do is test it :). so connect the motor modules to 5-6v battery and the RPi to a micro usb but NOT connected - only connect ground from the battery and moduls to the GPIO right? thanks
+aran everitt Yes. Just be aware that 6V are slightly above the rating of the stepper motors which is 5V. You could insert one or two diodes in forward direction to lower the 6V of the battery.
oooh, this guy
