Hi. I have created an issue on the GRBL repository. https://github.com/grbl/grbl/issues/656 It does look like its an firmware issue cause 0.8 does not do it.

When connecting to the board, I receive “YYYYYYYYYYYYYYerror: Expected command letter” what’s up?

Inkscape is good for drawing images. It also has plug-in’s that can convert the drawings into G-Code. The G-Code files can then be sent to a GCode interpreter like GRBL or MACH3.

I’m starting to build my own CNC machine, and I’m trying to get a software that I can draw and another one that I can do that GCode automatic. Can you help me. I have a TB6660 controller. And 3 axis. Thanks

No changes needed to the GRBL software. Just use X and Y commands. 😉

A newbie here, I want to run 2axis X&Y with a laser. What changes to the code, if any would need to be made? Would I comment out any reference to Z?

Have made the board so it can be done, but most people just use the extra axis to copy X/Y/Z. Have not seen firmware that takes advantage of the 4th axis yet.

Is anyone got ready compiled GRBL Arduino for 4 axis like Marlin as this GRBL is keep coming up with error on compilng.

It works perfectly fine. Just make sure to select the correct Nano. 😉

Hello! Is anybody try this library on Arduino Nano?

Hi Peter,

Yes that is an option but you can have a look at Ramps as that already supports it.

The newest version says:
Supported hardware:
Arduino Duemilanove
Arduino Uno
Arduino Mega 2560 (Limited Testing)

So if I start playing on the 2560 and include LiquidCrystal and SD – that might still be an option?

Hi Diego,

Is LabVIEW adding an return character after each line? I know I had similar issue with the Arduino IDE’s serial window.

Hi. This can be done with a Raspberry pi… This link is a great example of this : http://www.instructables.com/id/Raspberry-Pi-Alamode-CNC-Controller/

Thanks, Bertus. I could send some g-codes through Arduino serial port.
I have another doubt. I would like to send some g-codes using LabVIEW IDE.
I’ve connected Arduino with GRBL firmware on my computer and I communicate it with LabVIEW. However, I write some g-codes through LabVIEW and it’s possible to see the Arduino RX light on, but I cannot move the CNC stepper motors. I think the LabVIEW program is doing everything well, but the GRBL firmware is not able to read the code that I write in LabVIEW.
I do not know if you can help me! I’m just believing I can have an answer.
Well, thanks for your replies.

hello liked this project.
worked very well.
how to trigger the Arduino remotely.
example, a software to send the code g via tcp / ip and could use another device to receive this code (via tcp / ip) . and sends to arduino via serial.
you think works.
I thank you.

The Arduino IDE Serial Window can be used but you will have to toggle the setting for when a return character is sent or not. Example “?” does not need a return(“Enter”) char at the end but “G0X100” does. The Arduino IDE Serial window has a little drop down box in the bottom corner to set when it will add the return character or not.
