So this setup for the BeagleBone Black runs LinuxCNC and a small web server, to control it you login via Ethernet?
Interesting setup, that. I do that quite often with HP laser printers and I've remotely updated and operated Portmasters hundreds of miles away. For the control peripheral board (whatever their cutsey name is for the BeagleBone series) I'd say skip rebuilding the parallel port wheel and design one to directly control as many stepper or servo driver/amplifiers as possible. To offer options on the number of axes, design one board then just don't fully populate it for versions with less than the maximum. That's what the big computer component vendors have done for a long time, especially for OEMs like Dell and HP where you'll often see empty spots for slots and connectors and chips the company ticked a delete box on the order. It'd save a bunch on design and production costs, and sufficiently motivated people could add more components and update firmware if they have a need for another axis. I put together a 1Ghz PIII last night for what'll be my first CNC homebrew machine. Got a much beefier one that will most likely go with a CandCNC Dragon-Cut kit on a large plasma table. After those, this BBB system looks like it could be cheaper, smaller and easier to use, especially for "lights out" unattended operation. ------------------------------------------------------------------------------ Try New Relic Now & We'll Send You this Cool Shirt New Relic is the only SaaS-based application performance monitoring service that delivers powerful full stack analytics.
