CNC v3.2.1 - electronics using DC motors and rotary encoders 

I just love the way this machine is used to make upgrades for itself.

I needed this lesson for a long time to help me with my encoder stepper build. Thank You for your dedication.

Your skill is in making the complex things very simple to understand you also speak English to a high standard i am a big fan and regularly come back to these videos for references it's also entertaining

Awesome, hats off to you! Very well explained as always, thanks for all the info!

Thanks a lot for you tutorials, i got really a lot of informations, maybe the best cnc-related channel on youtube.

Nice work!!! You have already implemented and tested what I have had in mind for years. DC motors plus optical encoders!

Very useful video. I learned something in the first minute that I didn't know even though I have a degree in electronics. Thanks for the practical way to determine appropriate current limit for DC motor and controller.

Man, this is just awesome. Great work, love these videos.

thanks for the video. your content is great and very high quality!

I love your Frankenstein CNC router.

You are a genius! A marvelous job dear friend!! Appreciations and Admiration from Indai!!

Great work, mate! I like these videos.

Awesome work :)

I really enjoy your videos

No words . You are legent

Very good concept

Awesome! Very nice. Thanks

I Miss this video so much.

super cool and super awesome!

I have to make an observation about the DC motors. DC motors produce EMF that opposes the applied voltage when they start to run faster. This reduces the current and consecutively the torque at higher speed. So this limits the speed of the machine while the motors are actually run far below their thermal limit. If you end up deciding that the motor can handle 1.6A of continuous current, you can use L298s with some sort of current limiting device and you can set the current limiter at 1.6A. Then you can use much higher voltage on the motor. By applying more voltage, some of it counters the EMF and still there is enough to keep the motor current at nominal value. The rest of the voltage is blocked by the current limiting device so the motor is always below its thermal limit.

Brother thanks I was thinking to use this system to make a CNC embroidery machine in which z axis will rotate the sewing machine spindle

excelente!!!

wheels + elastics wow. this is 4th world level engineering.

Great!

Can i use a controller 4 axis for cnc? Or just work with arduino?

this is upgrade for encoders and complicate for me😉

thumbs up from me!

Hi! I am wondering: instead of cutting aluminum encoder disk maybe you can print it on transparent foil on laser or jet printer? The teeth of the disc are black and gaps are transparent. Than glue it on the acrylic gear, divide the sensor to halves and mount them on both sides so the sensor "is looking" through the gear and sensor disc... Just to mention it :-). It is, maybe, easier to make... But again, one big thank for your effort! The videos are so good that I decided to translate one by one of all your videos.

FICOU LEGAL .. AMIGO ONDE É O FECHO O PROGRAMA ARDUINO PARA ESSE PROGRTO... MORO NO BRASIL IT WAS COOL .. FRIEND WHERE THE ARDUINO PROGRAM IS CLOSED FOR THIS PROGRTO... I LIVE IN BRAZIL

What you think about dc plus encoder or step motor? What is better?

Can I use linear encoder instead of rotary? to manufacture the cnc. thanks

Brother doesn't the z axis move automatically according to the design or it has to be moved manually

Hi Norbert. I want build 2 axis hot wire CNC. How i can delete Z axis in program? And second question- i use arduino nano and on fast motor speed a have many lost steps. How many steps per second i can receive without lost steps?

en donde hago correr tu codigo? en linux?? o en el ide de arduino?? otra pregunta, podria fabricar ese h brige de 43 amperes casero ? o seria seria mejor comprarlo??

good afternoon, thanks for sharing, I'd like to ask you a question: how do you run the software that controls the machine?

Hi, any reason you went for dc motors over steppers, which can also be found in old printers? Could you not use steppers? Great video.

Wow- again!

Hello! Thank you for detailed describe your project. But I can't run control program in windows. Do you have compatible control program for windows?

Thanks for this video, I want to ask you about the software( program) you used ?

What is the name of the software you are using to draw the wiring diagram? And thanks for the great video

Have you considered painting those plexiglas gears, and using them with the optical sensors directly?

If you put the optical sensors at different positions around the sensor wheels, wouldn't that allow you to use much smaller gaps and with that much smaller sensor wheels?

hello, can you give me some recommendations to build CNC? I can pay for consultation of course. Please answer

I installed ubuntu, i opened the terminal, i called the directory cnc_v3_2 but still do not do anything, i do not know how to compile the source with: gcc commands-CNC.c -lm -o commands-CNC

Something to note is that shielded CAT5 and CAT6 is very uncommon in North America; you only really find it in industrial settings with long cable runs and a lot of electrical noise.

which software are u using here?

I am planning to build a reprap 3d printer using arduino which I believe is similar mechanism with cnc, but most instruction on websites using stepper motors. Is it possible using a diy servo like yours in 3d printer? Can you tell me what software should I use? My reason change stepper with servo is cheaper. I like your videos btw.

Which software are you using to program arduino

Hi I have a 600kg milling machine with manual knobs that is old and have alot of backlash. I thought to add a chainwheels on axis and make holder for old drills and connect them with chain so can move machine on joystick and faster when necessary. Now when I saw your video I thought maybe is possible to use printer encoder tape with sensor so arduino knows it exact position in 0.1mm accuracy and then upload code to arduino to make it a CNC machine.. Do you think thats possible?

Problem finished software work UGS Ir grbl not suport wayang

Dear Sir. What type of file can be read, plotted? Files with what extension? Thanks for your attention.

the motors are steppers?

Damn it, Paypal Japan is shit and does not simply work for donations. "I'll be back" to donate after I got my credit card. You are the best on youtube. And I like your "I'll be back" ending. Thanks for your videos!

Sir i have error' with your command-CNC.c source. But just fine when i add sleep(0.8) on sendport() function. Will you update next version of command-CNC.c? What are necessary of MAX_arduino_buffersize?

good morning, I would like to thank you for sharing your knowledge and for the contribution to the electronic development also congratulate him for his very impressive project. At the same time I would like to know if you can help me with my project idea: I want to use your firmware of your project CNC_ v3_2_1 and overwrite it with GRBL to use it with GRBLGRU V3.23 software. thank you I would appreciate your acesoria.

Isn't there any software which is suitable to windows?

very nice project , plz make a video on software and codeing related video, I need help

The project i was looking for. ))) I downloaded zip CNC V3.2 and in connection diagram it's not so clear how optical encoders connected to arduino... I am going to use Arduino Mega adk, 180 watts dc motors with chinese encoders and 43 amp BTS 7960 drivers... At list i want to try... What is the speed limitation for now and what programm is more compatable with your code to control the machine? Thank you for your project! I will try to follow it. )

can you share with us the code used for this wonderfull machine? please ^^

the software of controller please

buen dia amigo excelente video quisiera hacerle una pregunta este principio se puede aplicar a las impresoras 3d

Why didnt you use grbl ? Bu the way excellent cnc and software!

it is really good work. i want to work more on stepper motor. Can you give me arduino codes of this project.

HALLO, es ist sehr interessant. Haben Sie weitere Informationen?

realy cool machine but i already built grbl machine

Hello, does the software need to calculate acceleration ? or not ? because there already encoder to prevent miss step. I want to make this awesome CNC too, and able to use my software github/ryannining/karyacnc on it.
