This was a great video, very well laid out. I have one huge suggestion, almost a request. Add 2 axis stepper control with Grbl and one servo for pen up/down for those that are looking to build a plotter. There are literally zero videos out there explaining how this works or how to do it and the way you did this video would be perfect for that. Please consider doing this, I can almost guarantee that video will get a massive amount of views and it’ll help a ton of people. Thanks for the video 🍻

[@JoeGoesXtreme]

This is a great video. When the probing command is sent to the arduino it moves the z axis and waits until the moment when a connection occurs between pin A5 of the arduino to GND. These pins (A4 and A5 are also used by the arduino for I2C communications).

[@julias-shed]

Really comprehensive overview found that interesting 😀

[@diyengineers]

Thanks! 😃

[@JustinTyme1966]

OUTSTANDING, thank you very much!!!

[@qman2279]

Very informative. Thanks for taking the time to explain G-code and go thru the software setup. Feel like I can build my own cnc machine now. 👍

[@diyengineers]

Awesome. Thanks for watching!

[@andreinah343]

This is super helpful. Thanks!

[@diyengineers]

Glad you liked it. Thanks for watching!

[@noweare1]

Just what I was looking for, thank you.

[@diyengineers]

Glad I could help!

[@mattgbarr]

Awesome video, thanks!

[@diyengineers]

Hi! Thanks for watching. Let me know if you have any other Arduino project ideas that you would like me to make videos on. Thanks!😃

[@donaldweeks7089]

THE BEST I HAVE WATCH .

[@vocaldeviation]

Incredibly helpful. Thanks very much.

[@lusher00]

Thanks for the video. You earned thumbs up and a subscription. Just my 2 cents but you could probably eliminate the phrase "go ahead" from your vocabulary.

[@Caelin338LM]

You're the best bro, thank you so much

[@diyengineers]

Glad you found it helpful. Thanks for watching!

[@JustinTyme1966]

I ran into an issue, after I downloaded the zip, I followed your steps verbatim but when I open grblmaster I see the examples folder but thats all, nothing else is in the folder. Any ideas as to why this might happen?

[@danieles4820]

same issue here

[@coa7966]

Did you solve it

[@mattgbarr]

@@coa7966 I got it to work by: 1) Downloading the extracting the ZIP file. 2) Finding the folder called "grbl" inside "grbl-master". 3) Copying this folder into the folder where my Arduino libraries are located. 4) Restarting the IDE. I hope that these steps help!

[@tesg9551]

Very nice explanation. Thnx

[@diyengineers]

Thanks for watching!

[@consolenichecsn6930]

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

[@fahzo3603]

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

[@HaseebAdnan0]

Hi bro, can you do this on ramps

[@mr.olsen.]

Thank you for the video 👍

[@diyengineers]

You're welcome! Thanks for watching.

[@macklandtube]

when you add library and select grbl why if it is looking for a .zip file do we pick a non-zip file. My setup never allows me to pick the grbl folder. So I pick the actual zip file and that errors

[@Superstocker669]

[@mrmillmill]

Incredible video! Is there any reason related to the circuitry that you chose to build the machine with the dimensions that it has? Would the machine be just fine if it was say four times the size and do you have any tips for a larger build and what is required to handle a higher power spindle or can a higher power spindle simply be interchanged without any other circuitry changes?

[@diyengineers]

I built the frame that size for a specific application. For the video I removed the specific mechanism and focused on the CNC GRBL basics. Had I just made it larger, it would have worked just fine. I would take the spindle output of the CNC Shield and feed it to a motor controller appropriately sized for what you are trying to power up (basically use the CNC as the digital signal to control the spindle's motor driver). Obviously power up the spindle motor controller based on its own set of requirements. Additionally, note that the linear bearings, shafts, etc, need to be sized appropriately, meaning all those have a max recommended load, so don't exceed those.

[@khoirulaluminiumstyle]

I have a problem with "Specified folder/zip file does not contain a valid library "

[@MarkRap]

Same here. found a solution I guess. Just unzip the 'grbl-master' folder, copy 'grbl' folder into your arduino IDE libraries folder and restart IDE

[@BillyLeeWilson]

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?

[@wardvervoort997]

Hi i have a question, i plugged my steppers exactly in like you did on the cnc shield but when i only want to move X, the Y also moves and this the other way around the same, when i move Y, X also moves along, how can i fix this?

[@zumri4474]

hi, how about the command after the program finishes repeating back to the beginning, thank you

[@czowiekznikad2062]

Hi, thanks for explanation. I have a question, I'm using v1.1 grbl and I did the same changes as you in config.h, however, UGS still sees Z axis and when I try to home, Z axis is moving while it shouldn't. Do you have any idea why is it like that?

[@MecMod_Homeshop]

Hi, very nice, please what about the servo? Will be very interesting and complete if you complete this series whit the servo GRBL and Arduino and code set-up.

[@ryforg]

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

[@Jim_One-wl4ke]

Very helpful indeed. Possible to do 6axis with 2 CNC modules? Thanks for your sharing ❤

how to control power of the laser on grbl

[@ronniepaul]

when i try to include the library it just keeps opening empty folders...

[@zebragrrl]

take that nested "grbl" directory, and zip it up into its own zip file, then you can import that using the step above. this seems to be a recent change to Arduino IDE that the import tool doesnt do folders anymore.

[@ronniepaul]

@@zebragrrl i found the solution on my other channel.. kzbin.info/www/bejne/j6jdaZ2koZmghZY

Thank you.

[@reaper060670]

thanks fr explaining it really clearly for newbies like myself .. Very much appreciated man.. I'm attempting to rebuild my 1st attempt at a CNC home build but it wasn't working the way I had hoped. I bought the CNC shield with the 4 small steppers but I also have a kit of tb6600's with the nema 17's and nema 23's. I wanted to ask if it's ok to use the tb6600's with the Arduino? I'm a complete newbie to this whole electronics game but I want to build this CNC machine. It's only using 2020, 2060, 2080 extruded Aluminium but I'm hoping it's going to work fine for my 1st proper attempt. I'm going to use belts and pulleys for my 1st real go at this. Even though I know it's better to use Ball screws for better performance with the Linear rails but right now I have what I have and I ant to use the belts for now. Eventually I will buy the Proper ball screws and other parts to build a better CNC machine but for now the belts will hopefully work for now. I might need to use stronger belts in the future when I go bigger with the extruded Aluminium but for now I'm using what I have. When it comes time to rebuild it I will keep the parts for a bigger Laser

when i click grbl-master then grbl theres more stuff popping up instead of just ending

[@stevenfernandes1748]

Hey man! I loved the video! I've been dreaming up an idea to work on out of my garage by creating a dispensing cartesian machine. I've gone over your blog and this video, but I need some help with the basics of mechanical assembly. Do you have a video of your mechanical build? If not, would you have like 30mins to do a Zoom or Teams call for some pointers? I would really appreciate it! I am in a pickle right having been laid off a few days ago and I'm really wanting to put some energy into this plan this week.

[@BruhBruh-ki8xr]

Hello Awesome video I learned a lot !! Could you explain a little more about your use of two cnc shields and how you make the two communicate I can't find anything online about it.

[@tesg9551]

Do you have a project on using the A-axis? Would it be possible to add a 4th axis to a desktop (3018 type) CNC router? I could not find any example project on this.

[@aaddmmiinn]

I loaded the grbl library into the IDE, but loading the sketch into the Arduino gives me: fatal error: avr/io.h: No such file or directory #include

I would send gcode from a smartphone to an old CNC Fanuc Sigma VC1000 that has an old rs232 serial 25 pin. After that I would monitoring this machine (maybe sending it some command to the serial and the machine could answer me about start, stop, allar, type alarm, but I don't know if it possible, maybe yes). Could you help me in this little project? Thanks.

[@DennisMurphey]

Very well done and informative, my parts are on the way for a simple 3 axis Mini Mill This will help me out a lot. But I wanted to use Fusion 360 to get Geometry that then goes to G Code. In 3D Print we have a Slicer, Is there a Slicer function for this DIY setup? Dennis

[@UzunKamis]

09:19 How did you rename it as *grbl XY only?* Will it work if I only rename the folder *grbl* before adding into *Arduino?*

[@aamirsamis]

Hi, I'm new to GRBL. When I extract the grbl-master, the resulting folder does contain a folder by the name of 'grbl' but it is not a zip folder and so is not recognized by the Arduino IDE 'add zip library'. Please, any comments that may help me. PS. I used the link provided by you.

[@DownhillAllTheWay]

Did you overcome this? I have exactly the same problem.

[@jushiprai9212]

Need the video thank you sir.

[@SantaDragon]

If I click "open" with IDE 2.x then it does nothing else as open the folder in the file browser instead importing it. What can I do? Do I have to install the 12V on the CNC shield that the stepper could work or is just to test the USB power enough to rotate the motors?

[@tobiasbrunner8634]

Im havin the same problem with including the file, have you found any solutions yet?

[@SantaDragon]

@@tobiasbrunner8634 Installing programs Arduino IDE and UGS; import library GRBL 5:50 to Arduino IDE; plug in your Arduino board and check that you choose the right USB port in Arduino IDE; then open grbl sketch by File > Examples > grbl > grblUpload; upload it to your board; close Arduino IDE and then open UGS; then follow 11:45 ... that workflow worked for me.

[@tesg9551]

Thanks for all you are doing. I am confused about the second Arduino running custom code. The Arduino running grbl is connected to the computer. The second one, with the shield is not. Have you uploaded a custom code to the second Arduino to operate the dispenser motor? Would you please explain this and may be share the custom code? May be, I am missing something. Thanks much.

[@noweare1]

I think he meant if you want to have a arduino control stepper motors WITHOUT using GRBL you can still use the shield without have to connect to a PC with Universial Gcode sender. And in that case you write your own arudino program using the pinouts that the shield uses.

[@universalsankuks2333]

Make vidio on tool path,and 8 hole on pcd

[@tesg9551]

I really liked your explanation. Good job. Can this setup for your custom dispenser be applied to a CNC Lathe? I think we can assign the X to the carriage, Y to the Cross-slide and the extruder to the spindle. Apart from the hardware, what differences would there be in the programming? Thanks

[@diyengineers]

Yes, it could be applied to a CNC. You would connect the CNC spindle output to the appropriate motor controller.

[@diyengineers]

Thanks for watching!

[@MKA667]

Very interesting video! I'm curious to know how your "non Z axis" works. I made a CNC machine myself, many years ago (using a couple of 16F84), with a Z axis that could only go up and down to some predefined positions. It used two moving elements: a motor-controlled guide, and the spindle carrier itself. The guide could only grab the spindle carrier from its bottom to rise it, or go down to release it. When the guide was lowered to the defined position, the spindle carrier was allowed to freely go down until it reached the guide again (there was a sensor detecting it). I used this approach because one of the main purposes of that machine was drilling holes, and also because it was very rudimental. The spindle carrier was spring loaded, and I could adjust the force of the tool on the material by manually adjusting the spring... very rudimental, I know

[@kevincartwright4028]

Hey what ate you powering the shield with? Is 12v 5A OK then limit outputs at each driver?

[@diyengineers]

The A4988 is rated to operate between 8V-35V and can deliver up to 1 Amp without heat sink (or 2 Amps with proper cooling). The CNC shield allows you to run the A4899 to their designed levels,. 5 Amps might be enough depending on how many motors you are running and what the current load is at a given time.

[@mfe1462]

6:06 When I try to attach the zip file, it just opens the file farther, rather than attaching it. If it matters, I have windows 11

[@DownhillAllTheWay]

I have the same problem.

[@HansAcx]

Problems moving X-Y axes of the 2D plotter. When I press the X+ or X- axis on the jog controller, the plotter moves at an angle, the same goes for the Y+ and Y-. When I press the slanted arrows it does move horizontally or vertically. The system works in reverse. How can I change that?

[@PandaZ-kh3ml]

i got same Problems moving too, when i click up(Y+) become Up and right (Y+ X+), did you solve your problem?

[@straighouttheshed]

can i run 2 servos independently and 2 stepper motors using GRBL and the same CNC shield?

[@diyengineers]

I don't think so. The Arduino itself will be running GRBL, so you won't be able to run a standalone Arduino code at the same time.
