Hi guys. My friend is building cnc router and we want to check how steppers work. We're gonna use Arduino Mega and I could not find right firmware , tried to upload GRBL-mega on Arduino Ide, but I guess I couldn't find the right zip.file. I downloaded grbl-mega(zip-file) and did everything as I've seen in tutorial, but when I try to choose folder (grbl) to upload in libraries,it shows empty. So, I wonder , if any of you know suitable firmware for arduino Mega to control cnc machine or which version of GRBL can be used . I'm really begginer in this stuff and any help will be appreciated. thanks in advance <3
All Yuo need is grbl.h. I ran it on an UNO so it sould be possible on a MEGA. Compile the grbl.h and load it into the controller.
Download the sources as a .zip file using the green "Code v" button and selecting "Download ZIP"
Unpack the "grbl-Mega-edge.zip" file.
Copy the 'grbl' folder (from the expanded 'grbl-Mega-edge' folder) into the 'libraries' folder of your sketchbook folder.
Select Tools -> Manage Libraries... to re-scan the libraries folder.
Close the Library Manager dialog.
Select File -> Examples -> grbl -> grblUpload.
Upload that 'example' to your Arduino Mega and that should install grbl-Mega.
Thanks a lot. It worked. But now I have a problem with ugs , it says controller doesn't work with this version of GRBl
