One of the things I need to do while working towards motion control projects is to practice some of the fundamentals.  I’ve worked with many of the concepts and mechanisms professionally, but more from the support end.  I haven’t touched the stuff for a few years now, and want to learn things at a more fundamental level.  In order to do this my plan is to pull motors and mechanisms from recycled equipment (printers, scanners, etc.) and set up a few labs for myself along the way.  Perhaps I’ll try to salvage some of the electronics as well with some good old-fashioned circuit bending.  I should be able to at least reuse motor drivers that are found, but for now I’m going to rely on inexpensive motor driver kits to allow myself more freedom to experiment.

I started playing with EMC on a simple home-build concept mill I built about 9 years ago and it’s been shelved for most of the time since.  I really enjoyed the experience of getting that to work and have followed several other software/hardware projects online since including EMC2 and the RepRap/Makerbot crowd with great enthusiasm.  A couple years ago I was even able to apply what I’d learned to a job running some small CNC machines for a manufacturer in Aurora Ontario.
