Getting Error compiling for board arduino uno

petejd · February 13, 2022, 5:31pm

Hi. I am totally new to using a cnc machine. I have built the cnc machine but I have no idea how to get the arduino to upload to the board correctly. I have added the GRBL folder to the library. I just get this this error each time. I have followed a number of videos but still having a problem. Any help would be great, thanks

you should give WAY more information about your setup...

Also this is the wrong category to post. I moved your post to a better place

Hi, As I said I am totally new to this so not sure what info I need to share ? thanks

Hi @petejd. I'm going to ask you to post some additional information that might help us to identify the problem.

Please do this:

When you encounter an error, you'll see a button on the right side of the orange bar in the Arduino IDE: Copy error messages. Click that button.
Open a forum reply here by clicking the Reply button.
Click the </> icon on the post composer toolbar.
This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
Press Ctrl+V.
This will paste the compilation output into the code block.
Move the cursor outside of the code block markup before you add any additional text to your reply.
Click the Reply button to post the output.

Read the forum guidelines to see how to get the most from this forum.

Please include the entire error message. It is easy to do. There is a button (lower right of the IDE window) called "copy error message". Copy the error and paste into a post in code tags. Paraphrasing the error message leaves out important information.

What is it You try to load into the Arduno board? Did You tell which Arduino?
You need a GRBL interpreter.
In my pc, now on the phone, I have grbl.h. I just compile and download it.
Note the driver board needs to grbl compatible. I ude a protooner board as driver.

If you have not improperly edited the configuration file, then this seems to be commonly caused by not installing the grbl files correctly, or having more than one copy of the files and the IDE is taking some of the files from the wrong copy.

What version of grbl are you uploading? Where did you get it?

If you have homing enabled, you must tell grbl the order of homing the axes. That is done with the the homing cycle or cycles. There must be at least one cycle defined. The config.h file contains information on setting up the homing cycle(s). Uncomment the defines for the order that you want or edit the file to create your own.

Here is how the homing cycles are defined for my 3 axis machine. Z homes first, then X, then Y.

 #define HOMING_CYCLE_0 (1<<Z_AXIS)   // REQUIRED: First move Z to clear workspace.
 #define HOMING_CYCLE_1 (1<<X_AXIS)  // OPTIONAL: Then move X,Y at the same time.
 #define HOMING_CYCLE_2 (1<<Y_AXIS)  // OPTIONAL: Uncomment and add axes mask to enable

You can make it so that Z homes first, then X and Y home at the same time.

 #define HOMING_CYCLE_0 (1<<Z_AXIS)
 #define HOMING_CYCLE_1 ((1<<X_AXIS)|(1<<Y_AXIS))

It uploads for me.

So you downloaded GitHub - gnea/grbl: An open source, embedded, high performance g-code-parser and CNC milling controller written in optimized C that will run on a straight Arduino as a .zip file using the green "Code v" button and selecting "Download ZIP"?

And you unpacked the "grbl-master.zip" file?

And you copied the 'grbl' folder (from the expanded grbl-master folder) into the 'libraries' folder of your sketchbook folder?

And you re-started the Arduino IDE to install the library?

And you selected File-> Examples-> grbl-> grblUpload?

And you selected Tools-> Board:-> Arduino AVR Boards-> Arduino Uno?

And you connected your Arduino Uno?

And you selected the right serial port under Tools-> Port: ?

And you clicked on the Upload button (a circular button with an arrow pointing to the right) at the top of the sketch window?

Then what happened?

Think I got it sorted now thanks
