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." ☺️
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)
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.
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...
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.
+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): ruclips.net/video/p1PwYa4Fdqc/видео.html
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).
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

+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).
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?

Kirk Nelson I am not the first tinkerer that has done that mod, there are many videos on RUclips 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!
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
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 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().
+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
+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.
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.
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
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
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?
+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.
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.
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.
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.

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.

Your a bad man,lol.
sir, I am so noob at this, can you help me, I can't make the program work...I think I followed your instructions It wont run the program..please help
If you had followed all instructions correctly, it would run, thus you must tell me at which step you struggled.
Noobs must learn to read and understand error messages or at least hand those error messages to an expert ;-)
Screenshots or pictures of your circuit or machine can also help to find what is going wrong.
Read how to get in contact with me on my pages:
