PCB milling tutorial?

Post by leisure cove » Sun Oct 26, 2014 12:45 am

Hello! I was hoping someone might be able recommend a tutorial for milling PCBs on the Shapeoko-- a sort of "Dummies Guide" for people totally new to the process. I've been having a tough time finding one, and figured I'd ask here.

I'm using Eagle 7 to design the boards, but seem to be missing a step somewhere along the line when it comes to getting from Points A (design) to B (milling). If someone could recommend a walkthrough I'd greatly appreciate it! Thanks!!

Try this --> http://blog.inventables.com/2014/02/cir ... oko-2.html

There is no video but it was done using Eagle to .dxf to Adobe Illustrator to .svg to Makercam.

What problem are you having? I also design my PCB in Eagle and mill on my Shapeoko.

Scott- I'm confused as to the exporting process from Eagle. I've tried exporting a .dxf from Eagle and opening it in Illustrator (to save it as an .svg), but the design gets resized (the pads are huge) in Illustrator which makes me think I'm making a mistake somewhere along the way.

Would you mind sharing your process with me? Thanks!!

I use an Eagle script called pcb-gcode.ulp which will generate several gcode files you can use with the shapeoko. The script generates a top and bottom files for etch, mill, text and drill. You can get the script here: http://pcbgcode.org/list.php?12
The script from last April works fine with Eagle v7. You just install the script on your computer, and from Eagle you go File > Run ULP... , then navigate to pcb-gcode-setup.ulp.
You'll see a dialog box where you have to configure a bunch of stuff like tool diameter, feed rates and so on. Be sure to read the user's guide:

You should read Scott's thread where he was walking through this early in his PCB experiments. There is some fantastic info in there.

THANKS! A huge help. I will download pcb-gcode and get started. Much appreciated!

And thank you for the link to Scott's thread as well!

Mach 3 is commercial software — you should contact the company regarding licensing issues.

I believe LinuxCNC is a free alternative — back up your system, get a second Hard Drive, or boot from a thumb drive or CD and try that?

I know this thread is old, but I just came across it during my search for PCB milling experiences. Anyway, I wanted to share another thread that is fairly well presented over on the Carbide3D forum: Great results milling PCBs from Eagle with the Nomad. Since the Nomad used the Carbide Motion software, I felt it was pertinent to this discussion.
