CNC Machine – Part 5: First Test

This weekend I finished wiring up the CNC machine and was able to get a first test going. The limit switches aren't hooked up yet - I was getting some noise on those lines (they are unshielded, pretty long, and run right near the stepper motor cables), and was getting a lot of "false positive" limit alarms. So I've got to be extra careful until they are fixed - but I couldn't resist trying to make something. Right now I'm really working in 2D - I'm just using the same software workflow I use for the laser engraver. But next weekend I hope to start messing around with some other CAD/CAM software to try something more substantial!
