So I got excited with this laser project and I figured I had everything, the uno, cnc shield, A4988 drivers and I figured I could scavenge some DVD drives so I did. The original video is this:


I got to the part where I would build that power control board he makes for the relay but when I tried looking at the files I found out they're missing.

So I looked for others and found out there aren't many Uno cnc-shield projects. I found 2 other nano projects:



And when I search in Google I get a few from the same dude of the original video but in each instance the file links are broken.

Can anyone recommend a good one elsewhere?

OK I've made progress:

Hardware
I've got motors wired to female headers and those pesky jumper caps or plugs (3xAxis). I'm sure I have a 12v power source for the shield and the laser is on its way and I'm sure I can rustle up a power source for it.

Software
I've downloaded grbl 1.1 and "uploaded" it to my uno and tested a g-command resulting in OK OK.

From what I understand I need to "flash" or upload the hex file to the Uno. I'm guessing the hex file is the image file.

So I'm following this instruction here for Mac:

So I either use the command line or the HexUploader app, right?

OK guys I've got it working from gcode sender on mac. So far I've only tried moving y+ and x+ button by button. I'm psyched!

I just have a question...is it normal my DVD drive motors, when activated, move fine but make noises like an arcade game as they move?!

I'm running them off the cnc shield with a 12V/2A power adapter.
