Hi,
I am a bit late here but he does not mention how to adjust the voltage reference for the A4988 and that is one of the most imortant steps in order you do nhot feed too much current into your motors ...
Yeah. I had to find someone else who explains this. And it was in an Asian country, and dude didn't speak english.
So that video with the math, and another to show how to do it, without the CNC shield.
You will need the following: Ardunino (duuh), breadboard, multimeter, alligator clips, test leads, experimental leads.
Calculator if you are bad with math (like me).
You feed the driver 5V (and GND), from the Arduino, short the Reset and Sleep pin.
Now you need some extra leads - connect one to the other ground coming from the Arduino, and the other directly to the mutlimeters red wire (Hot/Positive lead).
-That's the one that gets connected to a screwdriver.
Power it all up, measure DC voltage.
The math - do it depending on what stepper motor you have.
Will get one from work, Moons stepping motor, 24V, 200 steps (or was it 400?!).
These are a bit old, we do have real drivers at work - but they cost a lot, and they have a powersource designed for them.
Also, talking about electronics, does anyone here know PLC?
Getting one of them older Siemens "Easy" PLC boxes, 48 volt in, can change whatever output you want..
And hey, get one of the IoT shields, control the CNC shield from distance!
Also I noticed When I change the Z driver for the driver that was installed in Y, it sounds. Is there a way that this driver can damaged?
What is the Vref for the A4988 drivers and this motors? I'm was trying to run this motors with the same setup (Arduino Uno, CNC shield) and have no success.
hi im using the same stteper motor with a gcode but i have truble changing and controling the speed , it would be great to use some of your help tks .
can you please do the wiring of limit switches and also what to change in code /setting to make them work
appriciated
Hi, Thanks for your fruitful tutorial. Actually, my both stepper motors rotate in the only clockwise direction. While I have anti direction too but motor rotates only in 1 direction.
Такая же ерунда. Нашли как это исправить?
As you do the driver trimpot setting, I made the setting with 0.04 but the motors do not work, thank you.
Congratulations on the video.
Up to how much vtg we can give to the grbl?
Is it necessary to use arduino UNO type for every machine?
Is it possible to send gcode of any 3d printer to arduino using grbl shield..?
Thank U very much u solved my problem
How to add servo motor (sg90) to this setup?
Hi I have the same kit but I don't now how much should I calibrate the drivers for this motors 28BJ-48 I can't find any video on here can you help me?
Any difference for using only two stepper motors ?
Thank goodness...
i just started gathering the parts for a cnc and this video was helpful.
But i got 6 wired stepper motors....can u help me out with this.
There a 2 center tap wires and the rest 4 are the wires of the ends of both the coils. By checking the resistance between all combinations of wires, the highest resistance(
how can I calibrate my 28byj-48 engine to the a4988 driver because it heats up a lot
🙏🙏🙏Thanks,, Long time I'm looking this kind of tutorial. Just Sub.👍
hi there! I have a problem I hope u can help me. Why can't I upload the hex file to the xloader?tnx
Can we use the same setup for 3d printer!?
Looks good but it's very limited. Not everyone will want a mini CNC or plotter. What about trying to get a servo z axis with a Uno and Grbl shield. That would enable us to move up to a larger setup.
Does they 6 pins are need to be short in sets of 2-2
Good video i want to build this but you hover over the screen that fast move around i dont know what you are pressing. Could you do one just on the download and adding and saving image please then how to send it to arduino please. Many thanks Kevin
Is there any idea to use 4th axis
how to use with grbl
very nicely explained
nice video .keep the good work.
Can i use a 1.7v 0.85a stepper motor in this
28BYJ-48 5V what is the rated current needed for the driver.
Can I use a dc 755 motor as a spindle while using 24by-j48 stepper motors as XYZ axles?
No, I think, because the motor have low rotation (Compared to a spindle or a Dremel) and the steppers don't have much force so you need soooo low velocities or a thin and more brittle material to cut
Could be a very helpful video (except for the music) if you could PLEASE SLOW DOWN so we can learn from you. I can't follow along because you move too fast.
Hi i have problem here.What the power adapter used for?does it use to supply the stepper motor?
if i use power adapter 12v 2A and at the same time i use stepper motor 1.7A(max current),does it will cause damage to my motor due to excess current?and will it affect the motor driver a4988?
No, that current rating is how much it can output, but the real current will be determined by how much does you circuit demands, and that you should calibrate with the potentiometer in the small driver on the shield
So I just did this setup. Same motors and boards. It works. One issue though. I was just jogging the axis in grbl controller and I've noticed that the motors jog randomly in different directions. For example I'll press to jog the z axis in one direction and the motor rotates clockwise. I press again, it turns in the opposite direction. Any idea why?
Нашли причину?
Can the CNC shield be powered by 12v 1.5a
I'm using NEMA 23 Stepper Motor. Can I Drive it using same method as mentioned in video?
probably yeah
why we have to rearrange the wires to connect to cnc shield?????
plz answer this
I think must to use 2 so motor in serial connect....
An error was detected while sending 'M6T2': error: Unsupported command. Streaming has been paused ??? why ? Pls give answers
Hello good Morning.
congratulations for the project how can i assemble one step by step.
how to start the engine on arduino uno generico I bought the engines these ai in the video but I can't get them to respond right away they keep turning with crackling crackles if you can help me I would be grateful.
Yeah, well uploader forgot to mention - you need to actually setup the drivers for whatever stepper motor you tend to use.
What's the Vref in driver?
Can u use 12v 1.5ab
Can i use 12v 800ma as a power supply
where'd you get grbl code to upload to the Arduino??? pls reply
makercam ya no existe ¿algún otro lugar donde conseguir archivos .nc?
very good video but I have a query, what are the values in: step / mm axis (X, Y; Z), (step pulse, usec), (default feed, mm / min), (step idle delay, msec), (acceleration, mm / sec ^ 2). for me personally I did not work with that engines I have 10 of that and I have thrown them for the same I do not work step by step but I adjust them, only I work the nema 17, and the other do not work the link GRBL Controller , X-loader to review, greetings
In case somebody will also be interested in it, I can share my own experience. I've got my 28BYJ-48 12V motor working stable and predictable (as much as it is possible) with the following settings: 1/4 microstepping, travel resolution 1024 step/mm, maximum rate 300 mm/min (this is the key point!)
Could you please tell me more about all of what you did after all the wiring, I COULD NOT FOLLOW YOU ON THE SCREEN. PLEASE help.Thanks
Can we configurate it for 3D printer
Yes, but use the DRV8825 instead - more reliable.
Looking for something more advanced? Find the TMC2100 driver then, it can go at 1/256 microsteps, on the output of 1/16. Making it extremely quit driver.
It uses interpolation. It's "brother" the 2130, is even more advanced - SPI connection on top!
I think you can build a reliable 3D printer, CNC milling/lathe machine or even a laser cutter.
Back to topic, don't forget to get the TL-Smoother, so it moves more smoother (thus you actually want a better stepper motor driver!).
But.. Printhat is what you are looking for. Still, yes - we should be able to make a simple 3D printer with this.
Which kind of PSU did you use? I tried with mi CPU PSU 12 volts, with an external 12 Volts 1 amp PSu, even adjusting the right value of the VRef for a Nema17, and Nothing Happens, well it happens, when I press the Y buttons, only Y motor sound but without moving. When I press the X buttons, the X motor sounds, but without moving, and the X and Y seems to change values on the GCode Sender. and when I press the Z buttons, nothing happens.
The A4988 driver has a trim potentiometer on the end that sets the amount of current for the motor. You probably need to adjust this to a higher current to make the motors move.
Thanks for this video
Did you also rearrange the wires to blue>yellow>pink>orage, all my Motors have blue>pink>yellow>orange>red arrangement!
The color of the wires can vary from one manufacturer to another or even from one batch to another with the same manufacturer. You need to use an ohm meter to find which wires connect together.
Hola con una alimentación externa de 5v los motores no se mueven.?
Yes, the motors are rated to 5v but the drivers doesn't work with this voltage
Hi, what voltage do you use for the drivers? 0.5v?
0.10v
What is the software that work by this ardoino
This motors are not usable for cnc machine because of huge backlash. Also, a4988 drivers current limiting is not working because sense
resistors are too small(should be 1-2Ohms so it can be adjusted to provide 160mA current needed for choosen motors) and more this drivers can melt themselves because of that if you will power it with higher voltage
hello, how do i make a 3d printer with this project, could you make a video making one?
Hello, i got arduino uno, cnc shield and one drive. Your power supply for the stepper is 12v with
0.5 amp. I got one 12v and 2.5 amps... will i burn the board if i plug in this charger ??
TYVM
No! Until you got some short circuit, or similar!😊
Yes, It should be 1amp or MORE. The board will only use what it needs.
What about spindle motor connection in expansion board....????
The motors are rated for 5 volts but you are using a 12v supply on the breakout board, how is this possible without frying the motor? Can I use a 7.25v rated motor?
Mines get very hot. I hope not fried seems working still.But the tutorial is perfect for me who has no idea at coding but just printing 3D.I even add my old PS3 controller with Antimicro software ! If you know the solution for keeping motors safe , I would be happy to modify mine! I have the same setup.
Those steper motor are unipolar how to convert in bipolar please help me
Notice, if running a 24v stepper motor, ensure to have a cooling fan attached nearby.
You will need it.
Also, if you get with the pre-attached heatsinks, remove them, remove excess "pads", and use thermal glue!
I'll see if I have time to upload something to Sketchup, where you can copy a build of a working "base" station for the arduino+CNC shield.
I like how you shwed
Gods work
update your softwares pls :-( . your tutorial is the best so far for me but cannot download your softwares
thank you for every thing
Needed to know how to modify 5wires to 4wires! ✌
Same here
Maybe this could help someone else
th-cam.com/video/FLJGCZslOcM/w-d-xo.html
The 5V motor has been retrofitted to be equivalent to 10V.
Therefore, using 12V power supply will not overheat？？
Thank sir
hello sir everything is perfect work but y axis is not work and a4988 driver is demag and a4988 driver 5 time change. pizzzzzz problem solving why this problem plizzzz help me
Do you use heatsink on your drivers, if not, this may be the cause. If yes, then try limiting the current (you might be using power supply that can deliver current more than 500mA)
You are using 12V in the CNC shield and the 28BYJ-48 Stepper motor are 5V. Isn't it going to overheat the stepper motors?
I have NEMA 17 5V itd gonna be ok, or i must change to 12V ? Or can I use Low Voltage DRV 8824 ( drv works 2,4-10V) with CNC SHIELD?
How calculate that it?
If i use 12v 2amp led strip adapter to cnc sheild is it safe...?
2 amps power supply doesnt mean anything unless your circuit is flawed, or if its a constant current supply.
how can i make thise code as loop
Hello sir how do you buy that unit
Why my y axis motor doesn't reverse in universa code sender?
bhai esko mobile me use na8 kar skte kya agr kar sakte h to video bna kar uplode kar dijiye
I am giving 12v to cnc shield, but when measured with multimeter it shows 1v only. Why this happens like this?.
Please help me.
1 volt where?
I have same stepper but it has 6 wire how to modify it with 4 wire??? Pls give answers quickly...
6 wires means unipolar stepper motor (most probably)!
By checking the resistance value between them you will get each 3 wires are connected together! Then 1 of each 3 wires will have similar resistance value between the other two and this resistance value should be the smallest resistance in the stepper motor! Eliminate that wire or just ignore that wire!
Doing this for both 3 wire team you will have 4 wire on count and that's the bipolar stepper motor modification
we have to remove that resistor also dude
какое напряжение на драйвере А4988
hi. What happen with volts of motors? You have 12v but motors consumes 5v
They got hot and strong
Can we use 12v 2Amp for cnc shield??
Dude, you definitely need to get familiar with Ohm's Law: U = I R. Rewriting this leads to the expression I = U / R. U is the voltage, in your case 12 Volts. R is the resistivity of the circuit. That's fixed, it does not change. Therefore, the current I is NOT determined by the power supply - unless you change the voltage, of course... Bottom line: if a circuit works with 12 V, 0.5 A, then it will also work with 12 V, 2 A (or 5A, or 100 A, or ...). Do it the other way round, then you are in trouble: a circuit that needs 12 V, 2 A and is supplied with a power source of 12 V, 0.5 A will not work. Either the fuse in the power supply blows, or, in case there is no fuse, the power supply wil start smoking and smelling... Eventually you will blow up the power source.
@@f.schoonbeek7626 my motors are heating,what may be the reason please help
i used 12volt ,0.7A adapter
Sir 0.5 ampere not available what about 1 ampere. And I said 28bjy 48 motor 5 volt and adapter 12 volt will not cause any problem.
What is the use of that red wire
the motors move very slowly for me, what could be wrong?
SIR: Is there any way you could help me with grbl, I have xloader, I can find nobody to help me out, I have it built but can not follow along with your video. I am slow, I would like any one to help me out if possible. I HAVE ADDA. Thank You
How to modified steper motor 5 wires to 4 wires
Nice
Hey i want to make a cnc number printing plotter machine, problem is that, when i want to print a number using stepper motors then i upload my Gerber file when it works, but when i want to change my printing number then again go to pc, and chnage the Gerber file then upload, my work is not so great, i just want to print some numbers using stepper motors. so Arundio IDE have any library to without using Gerber i change my number from keypad and display.
This is my collage project, please TH-cam help me,
sir
can you give me cnc code 3 axsis
think you
is it work with mach3 ?
Nope if U wanna make this with MACH3 U must buy extension for MACH 3 ( for example on aliexpress) then use stepper drivers( like on this movie) and should be works...
Can I control l293d from grbl software?
No
can i use arduino mega too with GRBL shield ?
Vaibhav Kotnala no
of course you can
no. you will destroy the bootloader
The arduino mega has a different pinout and won't work with the simple GRBL shield. It isn't difficult to make the Mega work, but finding the information on doing so is.
It will work for dc motor?
No
my motors are heating,what may be the reason please help
How did u fix your problem? I have some problem, too
@@MehmetSaidYilmaz I gave 5V 2amp instead of 12v 2amp
I said this to no other but you. You are just awesome man. You are the best. You videos, the way you taught others how to build things ..man that makes it a lot easier although I am new to this thing. You got talent on how to make other understand easily unlike others who also taught. Even a beginning can understand your tutorial videos. I greatly appreciate it man. I say again, you are THE best! Clearing my doubt real quick while I am here with the Pro. Can I use the same parts and arrangements for a bigger and stronger motors that can cut steel? CNC machine for steel? Can I?
hi Where is your program cod for Ardoinu?
Don't follow these videos when they plug in those drivers. The orientation will blow out your board and your Arduino and your driver/s. I give thumbs down to those who do not explain the orientation of the driver installation.
👍
Nowadays makecam don't work anymore, a good alternative for it is carbide creator which is free and intuitive
I need the cood please
it must to modify the stepper motor
plz tell
@@ahmedali1463 yes ,it will not run with the 5 wires the borad only support bipolar steppers wich has only 4 wires
Sir link erorr. Can you give me other link. Please
Tell me the total cost of project
I DID THE CONVERSION FROM UNIPOLAR TO BIPOLAR BUT MY STEPPER MOTORS ARE OVERHEATING ANYONE KNOWS WHY?
Do u solve tthe problem? Because now ı am getting same proble
