I wanted to let you know I built this machine and it works really well.
I 3d printed parts that I designed after looking at how you built yours.
I had to reinforce the parts that held the motors a bit as the shaft was not at 90 degrees
because of belt tension. I ran it in half step mode which helped a lot because
my table is only 100 mm x 100 mm. I am really happy with those motors as they work better than
expected. Thanks, you provided everything that was needed.
I had a problem of ordering pcbs ,now because of your help it is easy for me to make pcb
I would suggest using basically any other stepper motor though. 28BYJ-48 contain a large number of plastic gears that result in tiny inaccuracies that build up over time. That's likely what's causing the slight inaccuracies in the circles. But really nice build!
the project is simply awesome and extremely easy to understand. thanks for sharing this project
Thanks. Very elegant and cheap. A detail: the backlash, we can see it on the corners. To eliminate it it's quite easy: one can suspend a light weight to the axis with a wrapped string. You have now a perfect and precise device. Thanks.
Thank you for presenting such an excellent video. The audio of your voice was a low in volume but an amazing thorough video.

Thank you sir bahut details me sari baar bàta di
Thanks man, this has been hugely helpful for the plotter I'm building
This one is soo good please try to replace those 3d parts with another one as everyone won't have 3D printers.And make the video more in detail..
Thank you..
All your CNC videos are very good keep going..👍
How much Power to input into the CNC Shield
How did u connect the drawing surface plate with the belt? Also how did u connect the Z axis pen to the tower pro servo? Please share some pictures.
olá mundo! estava precisando fazer algumas placas de uso pessoal e encontrei esses problemas também, mas resolvi quando usei a versão 0.48 do Inkscape, aqui funcionou tudo certo, eu usei os mesmos motores do vídeo e ficou show, só para fazer placas. parabéns pelo vídeo me ajudou muito.
valeu Herlon tava me quebrando aqui agora deu carto
Boaaaaa!!!!!!!!!
O meu está dando erro na hora de gerar o gcode no inkscape, será pela versão do programa?
@@jasoncosta3805sim sim, use a versão que o nosso amigo falou ali que vai funcionar
Hi.I have a problem with inskape.when I choose MI inskape extension It's not working.please help me
If I use a stepper motor instead of a servo for z axis what changes should I do in the plotter program?
I believe you can remove the jumpers or leave just one to have half step, those motors already has a large gear box inside, you dont need microstepping here, then you may get higher speeds as the GRBL has a clock limitation in the pulses per second for the motor step.
The arduino cnc shield plus the stepper drivers are for bipolar steppers. The 28BYJ48 is a unipolar stepper. I presume it was modified to bipolar for this project.
One can use unmodified motors with e.g. a ULN2003 driver if one uses a modified grbl file
Thank you for uploading the files to print, but I have a doubt the file of the platform is not the same as the video platform is flat in the video itself and the file has some modifications please explain me please
I love this! Excellent job, thank you.
Super video and idea. And why start point of circle have different position with end point circle? Mech. or SW problem ?
how can i control the angle of servo for pen up and down ?
Sir can you please say me how you have connected the y belt to the drawing base
I have done it successfully, I also want to draw a printed circuit but how can I determine the coordinates because the printed circuit is very small?
I build cnc plotter too and it is like I see in your demo and not draw object accurately. What causing it?
Awesome Project :)
For those having trouble with the servo. Make sure #include servo.h is included in the grbl.h file in the Arduino -> libraries -> MIGRBL folder. That's the problem I ran into. What was happening was the servo was turning to the max, stopping because there's a tab on an inside gear that limits it to 180 degrees. I clipped off that tab, put the servo back together, included servo.h in grbl.h and it worked.
Gwebo Celestron thanks for the suggestion
I have problems with the servo. GBRL does not want to work with the M3 command, no matter what I enter for the M3, it always moves on and begins to exist.
Manually I can not move it when I give the M5 command and release it.
Gbrl I have tried several versions of none working. When I added servo.h to gbrl.h, the arduino reports an error. Im asking for help.
I am using separate drivers for steppers instead of the shield .So ca you tell to which arduino pin should I connect the servo motor?
Very nice tutorial thank you.Can you share the hardware part the motor pins ? because ı couldnt move the y axis motor.
How did you connect the servo to pen holder
good question !
I just built one. X and Y work great. Can't get the servo to work. Squeals but doesn't move. Bought two - same with both. Maybe need to use 12v supply? I'm using 9v 1 amp. Frame is great. Print a Thing printed it for me. They did a great job and fast. Two improvements should be made. 1) Pen holder should be larger to hold an etch pen and should be made to be flush with front of Z assembly. 2) The rails holding the X axis stepper motor is flimsy. Should be thicker. Already snapped one side putting this together.
How did it turn out?
Hi, Thanks for your fruitful tutorial. Actually, my both motors rotate in the only clockwise direction. While I have anti direction too but motor rotates only in 1 direction.
Very helpful videos to me ... thanks for give us such kind of videos
can i use pulley with teeth instead of idle pulley?
This is going to be my future project
Can we use the same calibration procedure and software with a L293D motor shield....
Hello. My cnc's x axis is not working. All connections are fine but it doesn't move even though stepper motor is vibrating and rotating. I have made from 3D printed parts provided.
Carry on bro am also working on this projet
Did you made it?
Simplesmente impecável. Parabéns pelo empenho.

I made all by instructuion in the video and in web-site. But my servo motor rotate 360 all time. How to will make correct?
Thanks for sharing this project. Great !
why i cannot make file gcode. could someone help me?
it appears on the screen attributeError: "module" object has no attribute ' unittouu'
Hello, could you solve the problem? I also installed the inkscape extension and I get the same error, is there any other library to download? or how could you solve it? Greetings and thanks .. I await a response
@@gonzalobaez16
download the older version of inkscape else it wont work.
My pen is not moving in dvd mini pen plotter. What I have to do. Pmw pin in v3 shield can be change or not.
DEAR MR INNOVATIVE, CAN YOU PLS TELL ME WHY YOU USE 28 BYJ 48 MOTORS? CAN I USE BIPOLAR STEPPER INSTEAD?
Is it possible to create a gcode to draw diagrams on a PCB without a stroke, so that it would trot with one line?
Hi buddy I would like to know: distance between X axis clamps and y axis clamps so as how long are the axis rails.whats is the lenght of the timing belts too.THanks
is this marker pen especially for that or can we use any one
7:12, what was the A_0001.gcode file you chosed? It was just suddenly you picked without any explanation.
hi.
i like this project. i hope you are fine and also your projects be successful!!
thank you so much.
Thank you very much
Thank you my friend for this great demo it was really helpful.
Explanation is really awesome bro keep it up
my servo doesn't works. i've installed ink 4.7 and works well but i don't know how th serve is activated. when you done the pen support did you set any parameters? how the arduino can control the rotation angle?
nice video
use inkscape to generate the gcode and then upload the gcode to benbox. make sure you've burned the benbox hex file into the Arduino.
HI .Awsome project .Can i use Ramps 1.4 ? its GRBL compatibl with Ramps 1.4 .I try with Marlin firmware and looks fine expect Z axis. Thanks
Can you make new version use step motor for z axis, thank for this video
Can this same software be used to make a larger plotter , about 1 meter 1 meter square, successfully?
Hello I got an issue: the GRBL has a undefined feddrate error and the x and y rails have an abnormal behavior.
Can it draw complex diagrams perfectly
Awesome project. Can you please show me the link of the pulleys and the cnc belt you have used? Thank you.
Rigers Alvora I used these: www.amazon.com/dp/B075YN647Y/ref=sspa_dk_detail_0?psc=1
why use 1.6A and 14.4 W to connect it to the shield cnc v3?
Can i do this project using L293d motor driver IC,instead of gbrl.....?
Mérci pour votre aide 🎉
I am trying your methods. But, in my GRBL controller return "buffer is small" what this means?
Hey dude!, have altered the stepper motor, well, have you converted to bipolar motor, how this works?, regards
Молодец! Good work! What felt-tip pen did draw?
How did you design the 3d printed parts to hold the motors?
I made this my x and y axis are working but z axis servo is not working. Plz help
What voltage should be set for the motors on the drivers?
Did you have to modify the stepper motors at all? I thought the pololu drivers only worked on bipolar steppers, but the 28byj-48 is a unipolar motor.
Look for vids on converting these motors to bipolar.
how did you connect the pen and servo? please explain it.
nice work, thank you for sharing this video.
is this support 1000mm X 2000mm work area?
ruclips.net/video/aU3eqMynz-I/видео.html
what kind of your spring ? Pls tell me
try running them in 1/4 step mode or half step mode to get faster speeds.
800 steps/mm is way overkill for this build, it practically can do 20 steps and the pen won't budge from the lossenes of the axis and the pressure on the paper will just keep it in place.
i also found out that stepper drivers usually loose accuracy when driven with steps smaller than 1/4-1/8.
Hello.
I made plotter based on MIGRBL firmware.
It works, but I foung 2 minor issues with firmware.
1. I tried to use lasergrbl software to process images to g-code, but if I triy to connect lasergrbl to the controller it connects and disconnects immidiately.
Comparing with another cnc machine running unmodified grbl firmware (ver 1.1f) thi machine communicates with laser grbl perfectly.
2. Issue with grblcontrol program - I am using to send gcode to the plotter.
It communicates with MIGRBL, but Joge keys do not work. Anything else seems working.
Also with other machine it works without problems.
I tried to modify MIGRBL to report at power up the same version as working one, but id didn't help. I checked with terminal, that initial string was identical includding end of string (crlf crlf), but it must be something else.
Could be the problem that I uploaded code I compiled with Arduino isted of upload hex directly?
I did every thing same as you did but servo motor not working at all
please help!!!just some question!
-MIGBRL upload is the same of original GBRL or it is modificated for the servo?
-Can you upload a sample gcode file ,so we can try it and understand if we have problem with the hardware or problem to create the gcode file?it is ok the same that you use in the video.
-my motor don't change the direction...have you same idea?
-if i insert more than 30 mm/min in the feed rate motor don't move...just noise...i have your same hardware. thankyou a lot...bye Marco
Mr servo is moving only down position pls reply what should i do ??.
Dear bro. I have error: no data from COM port. When connect to arduino unk r3.
So can you help me. Thanks
how sir do i make the project field size between the cnc fields. for example we want a printout of 1 meter x1meter. to enter the how-to sir

hello can you help me ,i have axis problem ,the maximum limit of my Y axis is 58mm ,i enabled soft limit , i start to move Y axis from 0 , but it move only -58 , alarm comes when I tried to move on positive direction ,how to solve this ,i also invert axis direction but i won't work if soft limit is enabled,it work only when soft limit is disabled
awesome project and i can easily run it..
Thank you
Hello Sir,i watch your project and make it same but the issue come after put gcode into grbl , it show invalid I'd 28 and drawing made negative axis
Please help to resolve this issue

Can we make a 3d printer with this motherboard
Hi Mr Innovative, Is it possible to draw on a bigger space, for example for A3 size?
Yes you can .just adjust the length of the rails and modify the code with respect to it .But using bigger stepper motor is preferable.
Hi, excellent job man, I have one question, what will be the vref value of A4988 driver?
HELLO! Prasenjit Sadhu the Vrfe is not always the same, it strongly depends in wich motor you have, most of the nema 17 stepper motors use a 0.61 or 0.65, this may be a little bit different if you have a 1.2 A nema 17, for does you could use a 0.91 Vref also you can calibrate them testing the temperature, if they start to get hot in a short period of time, you could reduce The VREF starting from 0.95 and going down .15 or .2 units.
@@cemf4330 thanks a lot,
Hi, can i change the work area size to 500x500 mm ??
one question,my motor has got five connectors,how i can conect it.
How i can find the plastic holders which you had used for the motors and pen to hold
you need to 3d print it
Where can we got that 3d part that you use is there a sale product on that 3d parts
