Your one works like a charm and AccelStepper.h lib seems amazing. Even accelerating and decelerating motor, but first it DOES what I expected. I tried to use more common Stepper.h lib before, but had some issues with stepping and counting revolutions. It was blinking wild on ULN board diodes, humming motor, but not rotating. Your one brought me in the right direction. Thank you!

HOW, do you have a microcontroller on the side

Also without gbrl, is there an option to send g codes from pc to control the 4th axis also.

29:35 How are you using 3 CNC shields together.

Hello bro, can I ask if GRBL can be used to send real-time data from sensor or camera? I want to do apply camera vision to detect object to be picked by my pick-n-place gantry

Can you make your text editor and the text a bigger view?

Thanks for this great content and I like your teaching! where is the video to learn how to use openCV to track the green ball? I only see 12 video in this playlist? Could you also post that video please. Thank you!

I shot you an email if youd be interested in working on something. Let me know!

i cant get the code

Why do I need 2 cnc shields? Can’t I use one

Moron describes how he likes packaging for first 5 min

Can you share the code pls? :)

I don't know a single thing about coding but I still watched the video... Very well made thank you 😮❤

I'm working with Arduino MEGA + L293D connecting two servos to L293D Servo_1 (pin 10) Servo_2 w(pin 9) control via FlySky using VRA(servo1) & VRB(servo2) similar setup horizontal & vertical movement. Both servos move via VRA, VRB fine but constant jittering. I disconnected one servo from L293D and the jittering stop on the connected servo. Any suggestions would be greatly appreciated. Thanks for sharing video (at some point will get to using Raspberry Pi 5) always enjoy your content. Cheers mate!

crazy bro you save my life, i wish success for you

How to connect using arduino mega. I am not getting the signal pin connection only .

Where to download the STL files? 🎉 I am ver interessted! Thank you..regards from Berlin

i got an error WARNING: Communication failure, is the MFRC522 properly connected? Scan PICC to see UID, SAK, type, and data blocks... and im not sure how to repair it

amazing video

can i run multiple projects like taking pictures , object detection and facial recognition using the esp32 cam?

Hey I am still getting the "Globally Unichip Corp." on my USB ive tried to reimage and try again but it has not worked :/, any one having the same problem?

it worker for the first time , then didnt , i reset the arduino card , reuploaded the code , but nothing worked , any solutions ?

How did you make the camera case? Is it 3d printed by you or it is abailable online?

Great video+explanation+presentation! Thank you for sharing! Well done mate - NEW SUB 🙏🏻

Hi, I have 4 DRV8825 plus the shield, I am trying to hook up 4 stepper motors to a flysky rc transmitter and receiver but am having a hard time and I can't find any video on how to do it, do I need any additional parts either then the DRV8825 and shield to do so ?

Hi I am using nema17 stepper motor and DRV8825 to drive it but my motor driver is getting heated up even though my stepper rotates. Is there any reason for this happening?

no me silvio glacias

bless

pasa codigo papu

Thanks for video, essential but effective. The video is not fluid at all, is this because of the type of the camera? Is the camera accessible from a PC trough the LAN?

Can you explain what you did with the 12v converter? Do you have a model number for it?

I bought 2 of drv8825. I can adjust current on one of them using screwdriver. But the other one has vref value fluctuate. It keeps showing random value and then back to 0. Does it mean it's broken?

Could you tell how you put together the diagrams? Use some type of software or website

First, thanks for the series. RaspPi5 content is scarce and few are worthwhile. Second, I followed all the vids and finally got the ball tracker working (I'm sort of new w this). By pausing at the right places and using logic/code from the series, it worked! I'm a happy camper. I wonder if you can point me on where I can find answers, Google isn't helpful on these Q's? 1. There's jitter, actually more like stuttering, while tracking. Any ideas to remedy this? 2. Not sure if this is b/c of #1 but, if you move the ball somewhat quickly, the servos stop tracking. The camera actually keeps tracking but, it's as if it can't send the signal fast enough to the servos. 3. Any idea how you can speed up the servos (SG90)? Thanks again!

which website you used for making the circuit

How come, I can't get any voltage on the potentiometer on five DRV8825 I bought from China? Should I consider it bad and buy another one like from your link?

i tried to trace your examples page without any success.

Is GBRL same as Universal G-Code Sender? I just beginner.

This is great, I have made my machine for few works. I get error messages during idling. I 'd be happy if I am instructed on how to clear. Thanks .

Wrong, you should have picked Messi, the GOAT. 🙂

no core dump partition found esp32 cam can you explain that

can you explain no core dump

I don’t understand why the 220ohm resistor is needed there between button and GND1. If there is no connection, you don’t need resistor right? Why put an extra wire between GND1 and button there? Appreciate for any help.

With no current limiting in series with the LED and transistor, you should destroy the LED and/or transistor. What is the voltage drop across the LED, what is the voltage drop across the transistor and what is the total current through the transistor. While this may have worked for the components you used, it could be useless for random component choice. At what point of the conduction curve is the transistor?

Great video, thank you!!

Super useful. Thanks! (this video deserves way more attention...)

Can you share the code pls? :)

you cool

Sir can you do a copper with fan cause that's what I have and I'm new to tech so I am wondering what the degrees are on this raspberry pi 5 with copper heat sinks and a fan cause I might save up and get it

I'm a newbie and confused... I'm trying to control a single stepper motor using the CNC v3 Shield and a Mega. I'm interested in looking into GRBL in the future but trying to learn a little sketch code for now. I'm using the Stepper.h library which contains the line... Stepper myStepper(steps, 8, 9, 10, 11);. Using the CNC shield, I believe pin 8 is (hardwired) as the Enable pin. Plus doesn't my bipolar motor only require 2 pins (XStep and XDir)? I'm not sure how to mod the Stepper command to make this work. Any help out there in youtube land?
