[Pete’s] invented a product called an AIR Patch Cable designed to interface with an airplane’s intercom, and is looking to manufacture and assemble them himself — unfortunately, the circuit boards are tiny, and SMD components aren’t exactly the easiest to install. So he decided to build a pick and place machine to do it for him!
It’s not finished yet, but [Pete] has reached a major milestone — he’s finished the base CNC machine aspect of it. He opted for a kit build for the major mechanical components, the Shapeoko 2 — its a solid design and if you decided to make something from scratch it’d probably cost much more and take a lot longer.
From there he began selecting his electronics individually. He’s chosen the Big Easy Driver by Sparkfun to control his stepper motors, which supports a maximum size of NEMA 17 steppers, so he bought five of those too. To control it all, he’s using LinuxCNC which is an excellent choice — and if you’re not crazy about Linux, you can actually download Ubuntu 10.04 with LinuxCNC pre-installed for you to make it super easy — you’ll just need an old dedicated PC to use.
Once everything was setup, he wrote a quick program to control his future pick and place machine — he strapped a pen onto the Z-axis and it scratched out its first word: “Gangsta”. Cause you know, G-Code. Right? Yeah. Anyway, we’re quite excited to see how this progresses.
