Emergency Stop ButtonI’m continuing to work on the 3rd installment of the EMC2 and Servo tutorial, but I realized that I hadn’t seen any great treatments out there for simple e-stop implementations with EMC2 or otherwise in the hobby CNC realms. This is the solution I’ll be using as part of the tutorial apparatus.

Safety systems aren’t sexy and so from what I’ve seen in the community those who know what they’re doing quietly implement them on their own systems but then the rest of the hobbyists and newbies may not even be aware of the need for such things and in the rush to get a machine running and doing the sexy stuff leave themselves open to more risk than is strictly necessary.

Well I’d planned on spending the evening snapping pics and scratching out the next part in the inkjet and servo lab series, but when I pulled my trusty Olympus SP-350 out of the backpack, I discovered it made some odd grinding noises, extended and retracted the lens a couple times eventually displaying “Zoom Error” on the screen. ARGH!!!

Musings on the usefulness of inkjet printers for a variety of applications.  So ok, I’m not the only one who’s been thinking about this, but here I hope to actually do something about it!

Anders is playing with EMC2 and RepRap functionality as well.  I’ve experimented with some of his temperature control ideas already, but need to work at the PID tuning a lot more.

PyroElectro has a bunch of tutorials for all kinds of fun stuff like this basic DIY servo/encoder setup.
