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 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!
Thank you for presenting such an excellent video. The audio of your voice was a low in volume but an amazing thorough video. Owen Vinall from Down Under Australia.
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.
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..👍
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.
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 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
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.
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.
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
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
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. 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.
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
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.
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
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.
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?
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

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.
If I use a stepper motor instead of a servo for z axis what changes should I do in the plotter program?
I build cnc plotter too and it is like I see in your demo and not draw object accurately. What causing it?
